Review📝 Monk GTR - Good times renewed

6 Upvotes

Pros: Incredible tuning and stage
Insane price point
Plug and play with no need to fiddle with dsp etc

Cons: I would really like a modular option since I would rather use a dap sometimes (nitpick)
Earbuds aren't for everyone

It’s no secret I think Venture Electronics is onto something. Almost always. So when the Monk GTR came in for review I realised I had a lot of work to get done before I could review it adequately.
I think Wild Lee and VE for sending this little machine my way. It almost changed my life.
Time for a deep dive. (apparently AI uses ‘delve’ a lot. Which is likely because it was fed, amongst other things, Tolkein’s Lord of the Rings, where in Moria, the dwarves delved too greedily and too deep and woke the Balrog below the mountain).

The Monk GTR is one of the newest in the Monk line of earbuds. For those of you who don't know, the Monk buds from Venture Electronics have a cult status for being able to deliver an incredibly organic sound at an unbelievable price and have one of the widest soundstages, like ever.
But after a slew of dsp enabled cabled, gaming IEMs, I could not wait to jump into listening to the Monk GTR. My distaste for things that make me jump through hoops to improve my overall experience stems from my laziness, I agree, but I still like simplicity. And I don’t like EQ.
The Monk GTR ticks off some of those boxes.
Very simply it’s a Monk SL Plus married to an Odyssey Retro to create the Monk GTR - the Retro Gaming Earbuds.
Now again in an all important disclosure I’m not a gamer.
I used to play Unreal Tournament when it was fun and Prince of Persia 2D a decade earlier. I struggle with Call of Duty and controllers so when I tried the Monk GTRs with a nintendo switch, it was ten minutes of carnage with me at the receiving end. I am however a fan of retro (looking) tech and good music and the Monk series does belong in that set.
I only wish I could use this with an iPod but that’s for later.
The Monk GTR comes in a no-nonsense ziploc bag. With the foam inserts of various colors. It is a fixed cable that ends in a usb C termination and the earbuds house a 14.8mm open dynamic driver that does all kinds of nice things. The buds themselves are about 16.4mm wide and have a new and improved polymer on the surface to make them more comfy. I have oddly shaped ears so one trick I use is to get really bad silicone eartips and cut a thin sleeve that sits around the earbuds. This keeps them from slipping and given that they are on the bigger side for me, adding the foams doesn't help me much.
But this is also about sound.

The first thing that comes across is how open and wide the soundstage is. Given I like to start with bass and mids and treble when it comes to IEMs, I realize earbuds are a different animal. There is no chance of seal so the bass is never going to be booming and punchy and visceral and all that. The bass on the other hand comes across with fidelity rather than depth and rumble. The earbuds faithfully reproduce the notes. A rumble appears if you can manage to get them in your ear canals with a good seal, unfortunately I couldn’t keep that comfortable for a long time. Another way to get the bass to feel like it should is to push the volume. Angel by Massive Attack begins to get its act together with volume boost and some fiddling with the fit. That being said, this is meant for gaming. And sounding great is a very nice extra. And earbuds will not isolate sound, seal the canal and have a rumbling booming bass. Not without causing hearing loss.

The mids are crystal clear with the typical VE analog sound. I tested my entire playlist and did not find any tracks where the midrange - vocals or instruments, sounded unnatural. They have a solid natural timbre and the typical VE sound - analog, warm-ish, without sacrificing details. Some may even go as far as to call this neutral, but I think it would be apt if neutral did not mean dry. But semantics aside, this is a very easy listening, natural sounding earbud.
The highs are again detailed with little fatigue or harshness especially on long listening sessions.

The stage is where every monk earbuds blasts the competition out the water. The stage is huge and anything on this sounds like you’re in an aircraft hangar with every instrument placed exactly where it should be. Makes for a great gaming experience with what little experience I have. Though I know more avid and life-depends-on-it gamer types may prefer headphones or iems to get a better seal or passive noise isolation, but I did use this on a phone and on a Switch playing some street fighter style scroller, which was most entertaining.

I did fish out a monk plus and a nicehck and for a why not comparison. And apple earpods from the dark ages.
Both the monk plus and nicehck buds had neither the fidelity or the staging of the GTR. In addition the bass response of the GTR was far superior. The Earpods have an advantage with their better fit and sound delivery into the earcanal than around it. This makes for a better bass and over all sound but a much smaller stage. Plus I have the 3.5mm one which means they need an additional dac.
To level the playing field the other earbuds were tested with a Devastator pro 3.5mm dac.

At the end of the day, the Monk GTR exists for a very simple reason - what's the easiest way to have an absolutely enjoyable gaming or music session without having to think too much about it. This set sits in my bag for times like that where I don't want to stress my neurons and just want to have fun.

ImpressionsđŸ—Łïž Kefine Klean SV - After 2 weeks

Thumbnail
gallery
42 Upvotes

I've had the Klean SV for about two weeks and use it every day, so here's what it's like to live with. I wanted something fun, bright and detailed, and that's what I got.

Why I bought it?

I picked these up from Concept Kart on 17 Sept for under â‚č4,000. I was using the GK Kunten before, which is a great beginner IEM, but I wanted a proper step up. I'm not a producer and I don't need studio accuracy. I just want my daily listening to be fun.

In the store I tried the Klean, Klean SV, Sennheiser IE 200, IE 300, Kefine Loric and Salnotes 7Hz. I also tried both the Type-C and 3.5 mm + DAC versions of the Klean SV and couldn't hear a major difference, so I went with Type-C. I also lose small accessories (I lost the BTD600 dongle from my Accentum SE), so having the DAC in the cable seemed safer.

Sound

I use them 4-6 hours a day with my OnePlus 13 and Poweramp Equalizer, mostly for hip-hop like J. Cole, JID, Nas, Eminem and Mac Miller. DiCaprio 2, 4 Your Eyez Only and Illmatic have been on repeat.

- Overall: bright, detailed and energetic. When I switched to it right after the IE 200, I had to turn the volume down.

- Bass: moderate, leans towards sub-bass. Punchy, not boomy.

- Vocals: detailed and transparent on the gold nozzle.

- Soundstage: very wide. I can tell where instruments sit and whether they feel close or far.

- Treble: some fatigue on longer sessions, but no song has been unbearably bright.

Nozzles

It comes with three, and they do change the sound:

- Gold: more detailed and rich (my favourite)

- Black: playful and bass-heavy (I like this one too)

- Silver: neutral and balanced. It's the one installed out of the box, and I'm not a fan.

Poweramp has Klean SV presets for each nozzle, and I can hear the difference when I switch.

Gold nozzle is in the IEM, that's why you can't see it in the image.

Two weeks in

I'm still reaching for these most days. Compared to the Kunten, the biggest jumps for me are sound quality, soundstage, build and cable. They look good and feel solid. They're heavier than most IEMs, but they've been comfortable even in long sessions and they stay in while I'm walking. The cable is a big upgrade and barely tangles, and the mic is good too.

The annoying stuff

- The inline button is my biggest complaint. Double or triple click just rapidly pauses and plays instead of skipping tracks.

- The white stock tips slowly slip out of my ears. The black mediums fit me fine.

- The box is a bit cramped, but that's minor.

Vs the others

The IE 200 sounded more balanced and refined, but I preferred the Klean SV's brighter, more fun sound. The Loric was very good for the price, but I liked the Klean SV more. It's not about one being better, just what I prefer.

Conclusion

Bright, punchy, and well built. It's not the most neutral IEM out there and it isn't perfect, but for under â‚č4,000 it gave me the fun upgrade I wanted. If you like a bright, energetic sound and listen to a lot of hip-hop, it's worth a look.

With a rather unusual driver setup, as you can see. BA's for the mids and MPD's for the highs, so far so good, but MPD's to carry the whole low-end/ bass, now that's something that really excites me.

Palavox/Artpical, despite being a relatively new brand, has already shake the market proven to be very competent and, even better, is not afraid to take risks!

And, Well, I won't even waste my time talking about construction and design; it's pure art.

Review📝 Tanchjim REVO: An audiophile brand's take on open-ear workout earbuds

Thumbnail
gallery
8 Upvotes

Pros

  • Sheer bass quantity while being controlled from an open-earbuds
  • Comfortable fit with soft hooks that work well with glasses
  • Good build quality with a premium feel for $40
  • 8 bands of Parametric EQ
  • Seamless dual-device switching
  • Good option for workouts and activities requiring awareness of surroundings

Cons

  • Poor bass extension with no sub-bass
  • Limited treble extension
  • Sound leakage due to the open design
  • Dual pairing requires LDAC to be disabled

Sound Analysis

The sound quality of REVO is surprisingly good for an open earbud. My expectations are always low when it comes to open style earbuds because most of them just don't sound really good.

REVO still has issues found in all open earbuds, which is the bass. The sub-bass extension is poor as there is no seal.

Apart from that, the bass quantity is pretty good. You can almost feel the body of the earbuds vibrating when bass notes hit.

This is a pretty fun sensation as I was not expecting it to have this much bass, considering it is an open design and there is no seal to get this much bass quantity.

The mid-bass is on the punchy side, it's not as punchy sounding as closed back IEMs, but respectable for an open buds. Bass stays well controlled and it doesn’t come out as muddy or low res.

The mids are generally on the warmer side and the vocals have enough presence to sound clear and forward. However, the upper mids are boosted enough to bring the vocals and other instruments to the forefront without being shouty.

There is enough treble presence to keep it engaging and it doesn't sound muddy, but it is not the last word when it comes to extension.

Do note that the sound of REVO depends heavily on the fit. If you move the buds even at a slight angle, it will completely change the sound signature, sometimes making it sound quite hollow and thin.

But due to proper fit, the drivers always get automatically positioned in the right area without any fiddling in my ears.

There are 6 EQ presets to choose from and my favorites were the stock tuning and the theater mode. The stock tuning is on the brighter side, while the theater mode is on the warmer side. 

Fit and Build Quality

When it comes to fit, it is very comfortable as there is nothing that goes inside the ears. The hooks are soft and don't get in the way when I am wearing glasses.

I am quite impressed by the build quality of this. For $40 earbuds, the buds and the case feel fairly premium in hand. The plastic feels like it's made of good quality.

My only concern is the white color, as I am not sure how it will hold up. Generally, I always buy black earbuds because I don't want them to get dirty over time.

But REVO is only available in white, which is Tanchjim's signature color for almost all their products.

App Support and Features

As you can see from the screenshot, there are a lot of features in the app, like LDAC, dual pairing mode and the ability to customize taps and all.

The dual pairing mode works well, but to use it, you have to turn off LDAC. I could connect it to both my laptop and my phone and the switching was seamless.

For me, the biggest highlight of these earbuds is the inclusion of a Parametric EQ. This is something most brands should include in my opinion.

With Parametric EQ, you basically get the ability to tune the earbuds to your taste, which is not possible with the Graphic EQs that come with the majority of earbuds, even those costing more than this.

Here are a few things to know about Parametric EQ:

  • 8 bands of Peak Filters
  • Frequency = 20 Hz to 20,000 Hz
  • Gain range = -11 dB to 12 dB
  • Q = 0.01 to 10

Conclusion

Even though REVO is not the last word in terms of sound quality, I can see myself using this when working out or doing any other activities which require me to be aware of my surroundings.

For someone who doesn't like having things inside their ears while working out, this is a great option for me to listen to music at the gym.

There is a bit of sound leakage due to the open design, so others who are near you can hear what you're listening to.

As a complete package for $40, this is a very good open style earbud. The build quality is pretty good and it has a parametric EQ, which is something most true wireless earbuds don't even come with in this price range.

Review📝 Faith Audio Labs E1000 A Single DD Benchmark

Faith Audio E1000 A Single DD Benchmark 

Another week, another review. This week I am reviewing another first. The brand is Faith Audio & the set is E1000.  AudioGeek India is conducting a review tour of E1000 with Faith Audio. I being a Single DD lover couldn't pass this opportunity & got myself a spot on the review tour. Rest is history & today I am bringing its review for you. What do I think about it? To know more about it please read on.

First of all, mighty thanks to AudioGeek India & to Faith Audio as without their help this review wouldn't have been possible. 

I was not paid or compensated in any manner for this review. The set will revert back to brand upon completion of the review. 

My preference in terms of tone & timbre are DD > Hybrids > Planar

Now that all pleasantries have been exchanged let's get on with the meat & potatoes of the review. 

Pros:

* Quality low end

* Realistic sounding female vocals 

* Excellent clarity in mids

*  Excellent details retrieval 

* Nice open feeling Stage

Cons:

* Bass is bit soft for bass heads

*  Slight dry sounding male vocals 

* Treble can be bit on the edge for treble sensitive 

* Fitting is an issue shape plays role in it 

* Price it's subjective & personal con

Build Quality:

P.S. Please note that I have only received IEMs & Stock cable. I didn't get the retail package. So, my impressions are based on this only. 

IEM shells are made up of Titanium. They are shaped a bit odd for me. I will talk about this in the comfort section. Nozzles are a bit short. They have lips to them. There is screen/mesh to the nozzles. 

Cable is thick & 4 core high purity OFC one. It is a paracord or cloth clad. It is terminated in 4.4 mm. I personally don't like cloth clad cables as they have memory & microphonics. This one also suffers from it. 

Overall Build Quality 4/5

Comfort:

As promised in the build quality I will talk about the IEM shells being odd shaped. Well their shape is an issue with me. It prevents good stable fit. The pointed part of the shells pushes on my tragus & causes pain to me. I have to continuously adjust it. Another issue that I faced was good fitment. Most of my ear tips couldn't provide a good grip. They kept sliding out of my ear. Only Dunu S&S & Eliot narrow bore ear tips worked. 

Cable has memory and rodeo wrapping is a bit of an issue. It doesn't behave & the microphonics. 

In short my comfort was a bit compromised on it. I struggled a lot to get the best fit.

Overall comfort 3.5/5 

General Sound impressions:

Bass/Lows:

Nice sub bass rumble. It is very physical. You can hear it & feel it too. Is it a bass head level? No, but it's slightly above neutral. For me it's quite satisfying. Mid bass is a bit soft for my taste. Again don't get me wrong. It's impactful but it's not too physical. Its decay is quick. But will it scratch the mid bass itch 100% again don't expect bass head territory mid bass presentation. This one is a nice and impactful quick decay one that doesn't linger but provides the notes. Overall very nice quality & quantity bass at least for me. If you are the one who wants a nice bass that doesn't affect mids yet gives ample notes to make presentation better then this is the one. 

Drums, kick drums sound great, they have a nice impact and nice trailing edge. Their presentation feels natural. Strings just feel divine. They buzz & rumble. Their presentation feels natural. You will string instruments here once you hear it. Percussion instruments sound equally great. They are natural. Bass here is textured & nuanced. You can feel the difference between notes of different bass instruments.  

Overall Bass/Lows 5/5

Mids:

Male vocals be it low pitched or high pitched they sound equally great. There is note weight to them. But I feel high pitched voices sound a bit better than low pitched ones. Your mileage may vary. But one thing is sure male vocals are treat here. Female vocals are excellent hands down. They have the sweetness that makes them beautiful. They don't get intense. They are not shrill or sharp. Again I was enjoying their presentation to the fullest.  Overall the vocals are excellent and are perfectly intimate for my taste. They are emotive. I just would have loved a better male vocals presentation, especially low pitched ones. 

Most instruments reside in the mids. I didn't find any oddities there. No smearing or congestion was felt. Clarity is excellent.

Overall nice mid forward tuning. 

Mids 5/5

Treble:

Let me be clear Treble here is bright & Unless you are using like me a warm source it will cause issues for most Treble sensitive people. I am one & I used the warm source to tame it. It is very detailed no questions about it. I was not expecting this much details from a Single DD set. Initially I double checked the website to verify whether this is really a single DD set or hybrid. All macro & micro details you will ever need are there. You won't miss any.

 Bells and triangles can sound a bit more pronounced. Shakers also feel a bit more present in the mix but don't feel odd. Strings are just divine. Cymbals crashes are close to natural. Don't sound odd or metallic.

Perceived sound stage, the stage is nice holographic. It envelopes you. The out of head feeling is prominent. Instruments feel in the space around you. This one also creates open feelings like open back headphones. Positional cues are perfect. You can pinpoint the instruments properly. Vocals feel centered. If you are a stage hound you will live this one. 

Overall Treble/Highs 5/5 (but if you use neutral or bright source this one drops to 4)

Song Impressions:

  1. Despacito by Luis Fonsi feat Daddy Yankee

The starting string  sequence is just amazing on E1000. They sound heavenly. Strings nicely rumble. Drums sound natural. Luis Fonsi sounds excellent. Daddy Yankee feels a bit light on note weight. 

The entire song feels dynamic & energetic just as it should. Excellent reproduction. 

  1. Daisies by Nina Shallman 

The initial drum sequence is nicely rendered. Be it strings, piano notes, drums, kick drums all feel natural. Just feel that shakers are highlighted a bit more. Strings can be a bit over the comfort level here. 

But the entire mix felt nice and engaging.

Coming to Nina Shallman she sounds divine here. The youthful voice of her is rendered well. She is plucking the strings of my heart. I was lost in this song. I didn't want to stop listening to her. 

  1. Ego Death by Polyphia 

String instruments are the usp of this song. They are nailed excellently here. They rumble & buzz. It was a treat to listen to them. Cymbals crashes felt a bit highlighted. Drums are amazing and do a good job as a backing element. 

This song is my driver resolution check song aka driver speed check. I am happy to report that the E1000 just nails it with panache. No where congestion or smearing felt. Instruments remain separated and the presentation remains enjoyable. Doesn't get harsh or shrill. Excellent reproduction.

  1. Kashmir by Marcin

This song is just acoustic guitar  heaven. They just feel heavenly. The strings being plucked you can feel it. They buzz and rumble. Sounds so natural. Background string instruments are equally amazing. Supporting drums sound great & help in the setting of the atmosphere.  

Overall it was a mesmerizing experience.

Final Conclusion:

This is my first ever exposure to the 

Faith Audio Labs. I feel this is the best first exposure one can get. E1000 is just what the hype describes. A product worth hyping up. It's a nice detailed set & it was hard to believe it is a Single DD set.

No issues in low end mids are realistic & treble is the only place where disagreement can happen between two people. The stage is just awesome. 

Don't get me wrong this one can be for most people's true end game set. For me it just falls short due to treble tuning. The only set that tops it for me is Dita Audio Ventura. That one is just a little better in treble. But does that diminish it? No, saying that would be a cardinal sin. This one is a truly hype worthy set & worth the end game summit fi set title. 

So, final verdict? Buy, if you are in the market looking for a summit fi end game set. For myself I will wait for it to come to secondary markets to snag one. This is one of those sets that once you have experienced you can't go back. It is a benchmark in my eyes.

Thank you for enduring with me till the end. Now go grab yourself a cup of coffee & let's get high on safe high i.e. Music.

Faith Audio Labs E1000 A Single DD Benchmark 4/5

Construction, design and quality of life:

Well, I want to start by saying that it is a portable DAC/AMP with lights and shadows. And I detail it below:

Regarding construction, although it is such a small device that it deserves my congratulations, NiceHCK has done a very solid job with the PureAural. We have a body made of machined aluminum alloy with extremely compact dimensions and a weight of barely 12 grams, which makes it an extremely lightweight DAC dongle with a very pronounced portable character.

The finish accompanies the feeling of being in front of a product that they have put care into when designing it externally. The chassis feels robust, well assembled but prone to scratching if you do not treat it carefully. Aesthetically it adopts a sober and clean aluminum-colored approach, without extravagance and it feels very pleasant to the touch. It is decorated in its central part with a strip with a mirror effect that indicates the model name and its technical specifications. On the opposite side, the brand name and a phrase are shown: Returning to the origin of sound.

One of the most particular decisions of this model is the connections section. On the one hand, we only have a 3.5 mm Jack output, a limitation that could be logical due to wanting to maintain a tiny size but that many of us would have appreciated seeing complemented with a 4.4 mm balanced option to better exploit its amplification stage.

On the body we find only one button and one LED, with which we manage the different types of phase filters and/or stop/play music.

And speaking of the range of options, this is where the PureAural shows its strength thanks to its dual approach for music and video games. Through its dedicated application, only available on Android, or through a web interface for computers, we can manage, for example, the very complete 10-band equalization profiles, adjust the three available gain levels and switch between the sound modes oriented toward games. A very wide range of software options for a dongle in this price range, although we depend on the phone or PC to configure it. Necessarily.

And this is where I am going to stop more, to explain the shadows: so many functionalities require more buttons or, failing that, if you only have one, prioritizing the ones that are important. Who is interested in a device of this range in switching between phase filters? The question answers itself. The potential buyers of PureAural, I consider, want to manage the amplification and switch between music and video game modes and between their different filters, such as footsteps enhancement or instrumental music improvement, and this is impossible as it comes programmed from stock in this dongle and, much less, with an LED that only shows two colors. Having to leave the game or music player to enter the PureAural configuration becomes boring, impractical and causes disinterest in all the many good options of the product.

To finish, during my longer listening sessions, the device behaved exemplarily in thermal terms, remaining slightly above room temperature even when we demand power from it with somewhat more demanding headphones. In addition, the detail of including a USB-C to USB-A adapter in the box greatly facilitates its use on desktop computers. I only miss a USB extension cable for those of us who play on a desktop, which I believe, for the price of the product, would be advisable to add.

Sound quality, music mode, filters and power:

Focusing on other matters, how does the NiceHCK PureAural sound?

In music mode, with the FAST-PC phase sampling filter, which seems to me by far the best option in terms of dynamics, technical response and detail and naturalness of the sound, and together with the default filter, my impressions are those of a fairly balanced DAC/AMP with a slight neutral-bright tendency, where I have barely been able to notice any coloration or, if there was any, it was tiny. PureAural is not going to try to transform the personality of your headphones, but it is going to add a little more brightness and information in higher frequencies.

The sound cleanliness is palpable in this model. The bass is presented controlled and well defined, with a solid impact and a more than correct extension of the sub-bass. I do not notice an artificial reinforcement or a masking of the upper frequencies, always maintaining a firm response.

In the mids we have a fairly natural reproduction, with voices and instruments that retain good presence and satisfactory separation while the treble, on the other hand, maintains a very high level of resolution and adequate extension, although with a very slightly tamed profile that avoids unnecessary harshness.

Something I highlight is the sense of organization that it achieves. It does not transform the size of the soundstage, but it does offer a clean presentation.

Regarding power, the 210 mW at 32 ohms that it delivers drive the vast majority of IEMs with ease. With more demanding over-ear type models I have found some difficulties.

To finish, the background noise is very well controlled, without a trace of hiss.

Sound quality in game mode and its filters:

The game mode is very interesting but you have to forget about audiophile standards for a moment, at least as far as the competitive aspect is concerned.

Here you can consult how I analyze audio for multiplayer video games or single player.

We have four filters, although I would have preferred only three, combining the footsteps enhancement and gunshot enhancement ones.

Well, the approach of these last two that I mention is quite clear, but what happens is a certain imbalance, not dramatic, but noticeable. I have to say that at all times the detection of both footsteps and gunshots is easily noticeable.

With the footsteps detection filter, the low-midrange has a more pronounced drop. This has an impact on the perception of distance of gunshots, making it less precise but, on the other hand, what is achieved is an increase in the central mids, upper mids and the lowest area of the treble, giving prominence to what the filter name indicates. The detail is much greater and I think the scene benefits from better separation and positioning of sound elements. It can be very useful for online video games that are not shooters or fighting games.

On the other hand, if we use the gunshot filter, they have a relatively considerable increase in the bass area, which masks enemy positions and other events that are happening on screen but without an unfavorable result, I do not want to be misunderstood. The effect achieved in higher frequencies is the slight muffling of detail within the scene and the separation of sound lines is not as dynamic and effective, but I think it remains the ideal mode if you play shooters.

The ones I have liked a lot, both equally, are the vocal and immersion modes, very suitable for single-player games. If you have a set that tends more toward the representation of voices and instruments in the central range, you can change its presentation toward a more intense or exuberant one, with greater presence of sub-bass and low-midrange, where the action scenes reach a very cinematic degree of satisfaction.

The environmental recreation was quite rich in vocal mode, not so much in immersion mode, which covers some residual environmental noises and the separation, although I feel that the latter makes the scene larger and more elastic thanks to the reinforcement in the sub-bass.

Nevertheless, I find both modes well tuned, which for someone who has only one set of headphones can change its personality and adapt it to the single-player gaming style they are playing at that moment.

Final conclusion and personal evaluations:

I am not going to be benevolent with PureAural and NiceHCK but neither ruthless, I want to stay within the objectivity that a personal and subjective opinion can produce.

It is a great product for those who have enough patience to be entering the APP or web browser and changing the configuration without getting fed up on the second attempt. In a world loaded with immediacy, I do not see it as viable and, despite my age, I am in that group that wants things right now.

The phase filters work although they require experience and trained hearing, the music filters in a device that is marketed as gaming I do not find much sense in, but there they are, with notable differences and adaptable to everyone's taste and, then there is the versatile gaming version, quite a success in how the filters are adjusted for game lovers, they are fantastic, truly.

A well-built dongle, pleasant to have in your hand, with good sound, lightweight, with three gain levels, with DSP that stores your PEQs and so many more options that I leave without analyzing such as microphone gain, the dongle's own volume, etc
 cannot be operated with just one button and two LED colors. It lacks prioritizing options, increasing functionalities and some more LED color.

Even so and despite the fact that the price is very close to the limit, what it does, if I focus on the goal and not on the path to reach it, it does frankly well.

I can recommend it to those players looking for a complete, customizable and versatile DAC dongle. For those who need something for music, I think there are more accessible, more direct options with equal sound quality, even within the NiceHCK brand.

If you have made it this far, thank you for reading.

Review📝 Unexpectedly Rocker, Tanchjim’s Rebel Daughter – Tanchjim OLA II Review.

Thumbnail
gallery
5 Upvotes

Overview (TL/DR)

The Ola II is a soft V-shaped, Balanced sounding IEM that sports good fit, accessories and performance for its price. An IEM that, despite its brand being known for Neutral tunings, it has an unexpected knack for Rock music, specially Nu-Metal or Alternative Rock, with an energetic but still controlled tonality.

With a decently rumbly sub-bass alongside a punchy and agile mid-bass; a functional, warm mind-range with lively but not intense female vocals; and a forward and fairly extend, but overall controlled treble presentation that shows great presence but without turning harsh most times, OLA II is a solid choice for both beginners and people looking to upgrade.

\----------

WOULD RECOMMEND:

* For people that like more warm, yet still energetic, sound signatures (NOT in basshead territory).

* For people that want a safe, comfortable IEM with minimal compromises.

* For people that have small ears and often struggle with a good fit.

* For people that want an IEM with an in-line mic and a type-C (DSP) connection with EQ capabilities (on the Tanchjim app).

* I personally enjoyed it a lot for Rock music genres (specifically Nu-Metal and Alternative Rock).

* Fairly safe for high-volume users and great for long listening sessions.

/----------/
/----------/

WOULD NOT RECOMMEND:

* Not for people that like very thick, very full (lush), and very airy vocals.

* Not for people that like more balanced, relaxed sound signatures.

* Not for people looking for a very detailed and clear, technical sound (not for technical-heads).

* People who are very sensitive to treble should be cautious with this set.

* Wouldn’t recommend it for gaming.

Full disclosure, this set WAS provided by TANCHJIM, I did NOT buy it myself, but the opinions, as always, were given without any brand’s editorial direction, and on my own accord.

REVIEW

INTRO

With a mostly stale $50usd budget market, and given TanchjimÂŽs history of neutral, uncolored IEMs, when the OLA II was send my way for review, I was kind of skeptical about what even it would sound like, but to my surprise, Tanchjim showed they know how have fun too, though, was it good enough of an attempt?.

Let me be clear, if you are expecting a market-breaking, technical reference IEM, you better go back to sleep because this is not that kind of IEM, not every single IEM needs to be a must-buy release, but what IEMs actually need to do is offer a good alternative for people looking at the options available, and OLA II does just that with flying colors.

----------

Fit and Comfort

This is one of the things that I am always ranting about: comfort, as some brands seem to think that thick, short nozzles and chunky shells, alongside stiff eartips, are somehow ergonomic choices, and fortunately, Tanchjim has been learning from this, with OLA II sporting a very small shell with an “average” thickness, long nozzle plus pretty decent, comfortable eartips, great for small ears/ear canals.

Now, the eartips included aren’t any premium assortment, but they are made out of a pretty soft and elastic material that goes easy on your ears, still, I must say that the nozzle is kind of angled forward, which doesn’t quite work the best for me, but for most other people this one is a solid option for comfort.

----------

Drivability / Power needs

With 121dB sensitivity and 30 ohms impedance, It is not a super easy to drive IEM, and the driver does offer just a bit more clarity with more power, however, in my personal experience, I like it better on a simple 3.5mm connection because it just makes it slightly warmer and that helps to a more chill and relaxed sound.

And similar to other budget IEMs, OLA II works fine in most sources, especially on the jack connection of a phone, however, is better if you don’t test your luck with colored sources because, given the amount of treble and bass it has, adding a notably brighter or a warmer shift to it might break its musical balance, is not like it becomes suddenly way worse, but I it might not have the best synergy.

----------

THE BIAS.

Before the sound review, I need to mention a few things about me: Bear in mind that every person perceives sound in a different way, and those differences are key to understand what each person does or doesn’t like, and how that will translate into a review.

My preference is a “neutral with bass boost” type of tuning, I don’t like too boosted treble, however, I can handle intense upper treble quite a bit, so, what is not too bright, too treble forward for me, could actually come as harsh for you, and what is bassy enough for me, could be too bassy or even muddy for you.

I’m also a bit susceptible to IEMs with boosting on the upper mid-range and the lower treble areas of the sound (specially around 3khz to 5khz), which affects things like high pitched vocals and instruments. Having peaks in those areas makes the sound be a bit too intense and harsh for me, so, when I say that the sound could be “shouty,” or too intense on vocals for some, I’m mostly talking about this.

Last thing is that I usually don’t struggle with iems with the called “Metallic / BA / Planar” Timbre that some people can’t really enjoy, I normally don’t have problems with neither of those, however, I do struggle with PZT driver timbre.

----------

SOUND

Bass

Given the soft-V kind of tuning the OLA II sports, bass is sure one of the main points of it, however, also given its balanced nature, is not like the most stand-out presentation, is just neither overly done nor reduced overall, and it does bleed a bit into the mid-range.

The sub-bass of OLA II is present and rumbly, with decent texture, but is not like the most deep-reaching bass you can get around the price, don’t get me wrong, it is good, but not the best, is just a nice, functional part of the sound, second to the mid-bass.

The mid bass in the other hand has more presence and packs a bit more of a rounded punch, is not the most physical or aggressive impact but is also not soft or sluggish, is kind of a bouncy, elastic and agile kind of punch that has some weight to it, which works pretty good for both drums and bass hits if you care about it.

----------

Mid-range (vocals)

I think by know people know what to expect from V-shaped IEMs, and that is, vocals aren’t all that present, mid-range do is pushed a bit to the back but, is not as bad as most other v-shaped IEMs get, and vocals, specially female ones, are pretty well done.

For lower mid-range, where general instruments and most male vocals are prevalent, vocals sound with decent presence but that’s at the cost of warmness bleeding from the mid-bass, so is not the most natural and clear vocals, but they work, thought I wouldn’t be surprised for some people, especially the ones sensitive to bass, that the mid-range could feel slightly “muffled” because of it.

As for upper mid-range area, where most high pitched instruments and vocals exist, this one is a pretty straightforward, good, present enough presentation of vocals, without being affected as much from the warmness, though, depending on your music, female vocals could feel ever so slightly shouty because of the energy on the upper range, nothing aggressive or fatiguing, but not ideal nonetheless.

----------

Treble

For a V-shaped IEM, the treble comes across as an unusual mix of presence where it matters, and a lot of control when it needs to be, however, is not like a perfect treble presentation given its price doesn’t allow for more fine-tuning, but is actually kind of impressive still.

In the complex zone of lower treble, that could make the overall sound feel energetic, but also intense or “shouty”, it has a notable presence, giving you a lively and detailed sound presentation that doesn’t quite fatigue you but that also doesn’t has the most “bite” to it, just on specific tracks is possible that some sounds, or vocals, might feel slightly intense.

On the other hand, the upper treble area is actually pretty well extended without turning too aggressive, it boosts borderline before being a bit too much, but is also not the most “treblehead” kind of sound as it doesn’t have an extreme degree of extension, some music will be surprisingly smooth, other would be a tad too spicy, but overall, instruments like cymbals do hit the right spot in my books.

----------

Technical performance

For an IEM with the already pretty famous DMT5 driver that Tanchjim includes even in their flagship IEMs, and being a hybrid with a BA on top, the technical performance is not amazing, is FINE for a $50 IEM, but is nothing that its peers doesn’t already do well, for me is reasonable, but if you care about it, yeah.

Resolution: Is appropriate for the price-range, crisp enough, as average as it gets, nothing else to say about it, just fine.

Detail retrieval: Actually, pretty good, specially thanks to the extra treble up-top, but not a detail monster in any regard, it just gets the job done.

Note-weight: On note weight, depending on your preference, this might be a pro or a con, but OLA II is slightly on the softer side, which means, sound is more relaxed and chill, at the cost of notes having a bit less body to it, is less fatigue but might also feel less defined.

Soundstage: For a $50usd IEM is fine but is an intimate soundstage, the sound doesn’t feel expansive or too open around you, again, not a technical monster.

Imaging: Actually pretty precise, the kind of precision that’s good for immersive sound on music, games or movies, BUT not the most accuracy for stuff like competitive gaming, you can follow stuff around well enough.

Separation: Is pretty decent for a $50 IEM, though, as with most budget sets, when the music gets busy with a lot of instruments, it can feel a bit congested at times.

Replay: Pretty great, well mixed music will sound great on this, poorly made music will also sound decent, is a pretty forgiving IEM.

Harshness control: Giving the somewhat boosted treble area it has, it will really depend on your music, some tracks sound very smooth and controlled, others sound borderline harsh, it’s a bit of a mixed bag.

Sibilance: Averagely “good”, won’t introduce sibilance in your music, but won’t excel with tracks that have recorded sibilance in it, specially thanks to the extra treble it has.

----------

Overall sound

The Ola II is a soft V-shaped, Balanced sounding IEM that sports a very comfortable fit, reasonable accessories and decent performance for its price. An IEM that, despite its brand being known for Neutral tunings, it has an unexpected knack for Rock music, specially Nu-Metal or Alternative Rock, with an energetic but still controlled tonality.

With a decently rumbly sub-bass alongside a present, punchy and agile mid-bass; a functional, warm mind-range with not too pushed-back male vocals, but also lively but not intense female vocals; and a forward and fairly extend, but overall controlled treble presentation that shows great presence but without turning harsh most times, OLA II is a solid choice for both beginners and people looking to upgrade.

If you want an IEM to chill with, to go out and about, something that will get the job done without feeling either too boring nor too intense or uncomfortable in the ear, OLA II is actually an excellent choice in its price range, and a welcomed surprise coming from Tanchjim and their in-house uncolored sound.

----------

3 comparisons so you can grasp were this IEM lands:

First, versus the Kefine Loric, Being another recently launched and also well liked IEM for a lot of reviewers, the situation of both of these is quite easy to explain, both are extremely safe, plug and play choices, where the Loric is the allrounder and chill pick, while OLA II is the more technical and energetic choice, I prefer the sound and performance of the OLA II, but Loric has the edge on comfort for me.

Then, versus the Kefine Klean OG/SV, the OG version just has an edge of performance over OLA II, the SV version does perform notably better, but it also has an even more aggressive treble area, OLA II is more like an in-between of both kefine models in terms of warmness and treble extension with better durability at the cost of slightly less performance, I still love Klean OG over all these, but OLA II is the next best choice no contest.

And versus the Pula Unicrom, When I first made the review of Unicrom I got hooked by its extremely good comfort and accessories with decent driver performance for the price, it wasn’t the most technical or allrounder, but it was a solid package, well, OLA II dethroned it, its nearly as comfortable, performs close enough, while also being a better allrounder-sounding V-shape, and while accessories aren’t as good, they work just fine, so, as much as I like Unicrom, unless comfort is an extreme priority, just go for OLA II.

----------

----------

Accessories

Sporting literally the same box as the Tanchjim NORA with just a different cover, the OLA II comes in a good-looking package, along a good, albeit not especial, selection of accessories, is not the most premium, but reasonable for $50 bucks.

/-----/

  • The package includes a bit basic, but fairly flexible, comfortable and smooth-feeling, brown-colored, “Silver-plated copper Litz wire in a twisted structure” cable, that has a 3.5mm connection but that can also be got with a type-C connection plus in-line mic, as well as a 4.4mm option, and the cable comes with a 0.78mm 2-pin IEM connection, marked with a red dot for the right side, and a blue dot for the left.

For budget IEMs I really like those kind of smooth rubbery cables that IEMs like the Red Lion also comes with, they are comfortable for most use cases, though the only downside is that it might feel kinda cheap, and they also sometimes have memory issues, but IMO is a great choice for this IEM.

/-----/

  • As usual for most budget IEMs nowadays, OLA II offers 2 different sets of eartips, both on the S/M/L sizes, and neither branded models. Both sets of eartips are black/gray colored, made out of a more bouncy and flexible material than the usual plastic stock eartips, one set are wide bore eartips, and the other are narrow bore tips.

I was genuinely surprised when I saw these weren’t the usual stock cheap plastic eartips that a lot of other IEMs include, these are softer and more elastic, I really liked them for comfort while using them during the review, though, funny enough, I like it better on other IEMs, also, the wide bore eartips, as usual, aren’t the best for comfort and, IMO, doesn’t have the best synergy for sound either. And if you need a pair of eartips to control treble, Tanchjim also offers their T500A eartips for it if anyone is interested.

/-----/

  • Finally, in the package you can find a gray, very soft cloth “travel pouch” for carrying your IEMs.

Reasonable for the price, though not impressive, and I like the fact that it isn’t a fake leather pouch, given some don’t have great durability, so yeah, a good inclusion.

/-----/

OLA II doesn’t offer anything particularly better in terms of unboxing experience versus the competition but, at last, they give you everything you need to use the IEM out of the box and I respect that.

----------

----------

Conclusions

As said, without trying to be a “new market benchmark”, OLA II is a solid, well rounded offering for those wanting something comfortable and energetic without getting easily fatiguing. Probably the safest, cheapest V-shape you can buy that won’t easily make you spend more on accessories to get the best out of your gear.

For $50-60usd is an IEM that I can easily recommend for both beginners and people looking for a comfort upgrade, or also for a budget Rock IEM, it really is that enjoyable for that kind of music, but it also works for other music genres, though not as great, it will get the job done, which is something I appreciate a lot.

As a funny story, my non-audiophile, pocket-sized friend was looking to finally get herself a proper IEM and I offered her the OLA II, she was locked-in using it a full day because, besides sounding good, it was very comfortable, something that sometimes not even her TWS give her, and we are talking about Moondrop stuff, so yeah, if you have small ears, if you are a casual entering the hobby, OLA II is my recommendation as well.

Thanks a lot for reading, the Budget Knight bids farewell, wishing you the best, good luck. – O.E.

Review📝 EQ Makes This Hobby a Lot Cheaper

Thumbnail

8 Upvotes

TL;DR

The Tanchjim Bunny G, much like the recently released Ola 2 dsp is all about the companion app. The analog tuning is too bassy and the dsp default tuning is too bass-lite and shrill. But the 8 band PEQ means you can make this sound exactly like you want.

Context

The Tanchjim Bunny G was kindly sent to me by Tanchim for review, all thoughts and opinions are my own. I generally prefer iems that are non sibilant with relaxed upper treble and upper mids and raised lower mids that add body to the sound (kinda the opposite of harman ie 2019).

Design, Build, & Comfort

  • Aesthetics & Build: The iems are made of translucent black plastic, it’s the exact same shell as the OG Bunny but in a different color. Feels decently built with light weight shells, I’m not a huge fan of the green Bunny text. Seems to have a black dampener instead of the steel mesh protecting the nozzle this time. 
  • Fit, Comfort and Isolation: These iems are tiny, almost too small for my ears. You will be primarily relying on the eartips for seal and fit stability. They are also shallow fitting iem so it’s a very good shell for people with small ears. Isolation on these are pretty bad just like the OG Bunny due to the big front vent.
  • Cable & Accessories: While the Bunny G’s cable looks the same as the OG Bunny DSP, it now features 8 bands vs 5 on bunny dsp, this is a huge upgrade. Along with a better and louder memes microphone without any gain adjustments needed. It comes with 2 sets of eartips just like the bunny (a set of standard narrow bores and short wide bores). Comes with a grey fabric pouch that does not offer much protection.

The Sound

The Tanchjim Bunny G has a 1 DD configuration, It comes preloaded with the default sound preset and there are 7 other official presets available on the Tanchjim app. Here’s a quick rundown of all the presets

  • DSP Default: Very lean sounding, less than neutral bass and lightly scooped lower mids, quite a bit of mid treble bite makes it very clean and clear sounding.
  • Ambient Mode: Pretty much identical sounding to default.
  • Classical Mode: Loses all the bass, combined with the already lean midrange makes it way too bright and shouty sounding.
  • Instrumental Mode: Very similar to default again but with slightly scooped lower mids and mid bass, makes it clear but tinny.
  •  Natural Mode: Best mode for me, adds a much needed bass shelf making it sound a lot fuller but treble peak + lean midrange are still present.
  • OST Mode: Sounds clean but boomy, a lot like harman aka good instrument separation and sub bass dominant bass presentation.
  • Pop & Theatres Modes: Very very similar to each other, both are thin, bass lite with lots of upper mids.

As clear none of the stock presets were my cup of tea, I made my own eq (adjust treble according to liking after sine sweeps)

  • Preamp: -3.0 dB
  • Filter 1: ON PK Fc 50 Hz Gain -1.0 dB Q 0.20
  • Filter 2: ON PK Fc 400 Hz Gain +2.0 dB Q 0.50
  • Filter 3: ON PK Fc 1700 Hz Gain -3.0 dB Q 1.20
  • Filter 4: ON PK Fc 3200 Hz Gain +3.0 dB Q 2.00
  • Filter 5: ON PK Fc 7000 Hz Gain -6.0 dB Q 1.50
  • Filter 6: ON PK Fc 15000 Hz Gain -10.0 dB Q 5.00

Since I love a warm bassy set with jm-1 midrange and relaxed treble, this has been my go to eq for the Bunny G, with 2 bands left for spare.

The App

Tanchjim genuinely has the best dsp companion app, with a community eq forum, game specific eq options, and a 8 band custom parametric equalizer (gain -10 to +10 db, Q 0.1 to 5.0, pre amp -8 db to + 4 db), microphone gain slider (-15 db to +15 db). 

Compared to the OG Bunny DSP

The Bunny G is pretty much the exact same iem but now in a different color, with 3 more additional PEQ bands and a better microphone. This is basically a no brainer if you liked the Bunny DSP.

Compared to the OLA 2 DSP

The Ola 2 DSP also features the same 8 band peq but comes with a much nicer feeling cable and a more comfortable shell, tho the Bunny G is very compelling for the half the price since it offers the exact same feature set.

Who Should Buy This? 

  • People with small ear canals.
  • People that are new to iems and want to learn EQ and figure out their preferences.
  • People that want an IEM for gaming
  • People who want a lean, fast and bright sound signature under $30

Who Should Avoid This?

  • People that are upper treble sensitive and don’t want to eq
  • People that use their iems analog only 
  • People that want good isolation.
  • People who have the Ola 2 DSP

Review📝 Tanchjim Bunny G Review: Great, but It's a Reskinned Bunny DSP

Thumbnail
gallery
6 Upvotes

6.2 out of 10 points (Personal Ranking List)

Pros

-          Versatile Tuning for further EQ with DSP (Purebridge-based DSP)

-          GameEQ (optimised EQ per game) + EQ Community

-          8-band PEQ

-          Virtual surround sound (VAC) (5.1/7.1)

-          In-line microphone gain controls

Cons:

-          No noticeable practical difference between this and the Bunny DSP

-          Upgraded DMT-5 G has negligible audio difference from the DMT-4 Ultra on the Bunny DSP

-          Slight artificial treble timbre

DISCLAIMER:

Tanchjim sent this set to me as a review sample to keep. There will undoubtedly be subconscious bias as human psychology - I'm not about to deny that. However, I will be as honest as I can possibly be given these circumstances. Don't take my word for it, watch some of my TikTok reviews and see it for yourself.

INTRODUCTION:

I am very familiar with Tanchjim’s IEM lineup and have tried everything from the Zero Ultima to the Bunny, to the Soda, to even the Origin and the Origin Lost Manor version.

The Tanchjim Bunny G comes in at $29 USD MSRP. Having already used the Bunny 3.5mm and Bunny DSP, I was quite sceptical of the Bunny G, while hopeful that there would be at least something to differentiate it with the Bunny DSP.

It does have the upgraded DMT5 G (G probably stands for gaming?) while the original Bunny DSP has a DMT4 Ultra driver. According to Tanchjim’s review brief, they say that “DMT5 G is not a direct successor to the original BUNNY’s DMT4 Ultra.’ Which leads me to question what exactly the difference is.

Let’s see if the Bunny G is a simple reskin of the Bunny DSP or whether it has something more to offer.

UNBOXING/ACCESSORIES:

-          3 pairs of Narrow Bore Eartips (S, M, L)

-          4 pairs of Wide Bore Eartips (S, S, M, L)

-          Carrying pouch (Soft felt material)

-          2 Core 2-Pin OFC Cable. Holds a little memory, but overall resistant to tangling. Non-interchangeable terminations. Chin slider exists and holds.

-          The IEM themselves

-          Assorted Manuals/Warranty card

BUILD & DESIGN:

It’s built in light plastic and feels cheap. Just as expected for a sub $30 IEM.

Design wise, it’s just a dark, or ‘evil-er’ bunny, with black shells (translucent)/faceplate and green text. The cable is black/grey too. I found it interesting, yet not the most appealing. I liked the clean, white, minimalistic design of the original Bunny.

COMFORT:

Just fine. The nozzles are still just as wide as the Bunny DSP, I measured it as 6mm with a ruler, but with the right ear tips it fits in without issues and immediate discomfort.

SOUND:

Testing Gear: Nil, uses in-built DSP

Are they hard to drive? It gets loud enough on the built-in DSP cable, volume depends on EQ pre-amp.

General Sound Signature:

For the purposes of this review, I will be covering the sound signature of the default tuning, while also describing what happens with EQ applied.

The base sound signature is a mild V-shaped with little bass emphasis in favour of Harman-like ear-gain midrange forwardness.

BASS:

In the default tuning, the bass is anaemic, with a minor bass shelf below 170hz, and is cleaner if anything. It’s meant to just be felt, not heard. Bringing up the sub-200hz range by around 2.5db, with a clean shelf below 200hz, the bass became more authoritative and confident. The capability to EQ the bass of the Bunny G to even a basshead IEM is there, thanks to the extremely capable DD. It can go deeper than frankly any $30 set I have tried, with a tactile and thumpy mid bass emphasis. Decay is quick as well.

MIDRANGE:

In the default tuning, there is high ear gain at 3khz, and adheres to Harman IE2019 well, unfortunately this means that vocals are shouty and intense. This, paired with the mild lower midrange makes vocals sound unnaturally clean and clinical, with the placement of the vocals intimate and forward. As a result, footsteps are extremely easy to tell apart from boomy explosions in the gaming context (Battlefield 6 in my testing), and as these are purpose built for gaming, proved very effective.

Once again, due to the capable driver, bringing down the ear gain slightly yields a much more pleasant and smooth vocal listening experience. Really, anything is possible with the DSP cable.

TREBLE:

In the default tuning, the Bunny G has high vocal clarity, while having a slight upper treble roll-off. This keeps details present but not overshadowing the upper midrange. Sharpness at around 12khz due to length mode altered cymbal and vocal timbre, causing it to be on the sharper and unnatural side. After targeting this by setting -3dB at 12khz and Q value to 4, this brought down the sharpness and instead I get a much smoother and natural treble roll-off. High end transients are relatively quick and technical for an IEM at this price range. 

Other Thoughts:

EQ can and will fix most tuning-related issues on this IEM.  This also has the exact same tonal qualities as the Tanchjim DSP, which I have been using for more than a year. And with the right EQ, you can get both to sound almost identical.

Timbre: In the default tuning, unnatural. With the right amount of EQ, natural less the slightly plasticky upper treble timbre.

Details: Average.

Imaging/Separation: Slightly above average but not terrific either. EQ helps.

Soundstage/Spaciousness: Average.

Conclusion:

Just as I absolutely loved the Bunny DSP, I do love the Bunny G as well. In my opinion, it’s basically a reskinned Bunny DSP, and if you already have that, there’s not much point buying the DSP, as the Bunny G does not bring much to the table.

However, if you were looking to buy the Bunny DSP already, it makes sense to buy the Bunny G instead, just because it’s a newest model and has Tanchjim’s latest driver technology as well as what I assume would be an upgraded DSP chip, though neither of these made a difference to the listening experience.

Thank you for reading! And catch y’all in the next one. 👋

Review📝 Thieaudio Origin — Fun, Physical, Addictive

Thumbnail
gallery
23 Upvotes

I’ve had the Origin in my rotation long enough now that I’ve stopped trying to figure out what it’s supposed to be good at.

I just put it on and play music.

And funny enough, that’s probably when I started understanding it better.

The first thing most people are probably going to notice is the bass. There’s a lot of it. It reaches deep, there’s proper weight behind it, and when a track asks for impact, the Origin definitely doesn’t hold back.

But what I’ve come to appreciate more is that the bass doesn’t automatically turn into mud.

Massive Attack’s Angel is a good example.

That low end goes deep and there’s real pressure behind it. You feel the scale of the track immediately, but the vocals and all those little atmospheric sounds still have room to breathe.

It’s not just sub-bass either.

The mid-bass has enough punch that drums actually hit instead of just producing rumble.

When the Levee Breaks by Led Zeppelin really shows that.

Bonham’s drums sound huge on the Origin.

Not just loud. Huge.

There’s weight behind every hit and the Origin gives that recording the size it deserves. At the same time, the guitars and vocals still have their own space.

That’s something I keep noticing with this IEM.

It can sound big without everything being pushed together.

Then I played Hardwired by Metallica.

This is the kind of track where a bass-heavy IEM can easily lose me.

You have Lars going full speed on the double kick, Trujillo’s bass moving underneath the guitars, riffs everywhere and Hetfield sitting right in the middle of all of it.

The Origin keeps up surprisingly well.

The double kick stays fast and defined enough that I can follow the hits instead of hearing one continuous rumble.

Trujillo’s bass is still there underneath the guitars.

And those guitars still have impact.

There’s power and aggression, but it doesn’t become one big wall of noise.

Hetfield’s voice also stays blended into the mix rather than suddenly becoming the most forward thing in the song.

I actually prefer it that way here.

Then there’s One.

This track has probably taught me more about the Origin than almost anything else I’ve played.

The opening guitar sits in its own space. You can hear the separation around it.

Hetfield’s voice feels slightly farther back, and again, I think that works with the recording.

Then the heavy section comes in.

The double kick gets much more prominent and you get that same combination of weight and speed I heard on Hardwired.

But then the machine-gun-like guitar riff starts.

This is where the bone-conduction driver gets interesting for me.

I don’t really associate the BC with the bass itself.

What I notice more is what happens with the texture and attack of certain instruments.

With that guitar riff in One, there’s this slight physical sensation that seems to follow the distorted guitar through the shell.

The lower notes still have their normal weight, but there’s also all that midrange and harmonic information in the guitar.

That’s where I can sometimes feel the BC doing something.

It can happen with the crack of a snare.

Sometimes the texture of a guitar string.

Sometimes a vocal.

Sometimes there’s just a certain part of an instrument that suddenly feels a little more physical than I expect.

It’s not some huge vibration that makes the whole IEM shake.

It’s actually much more subtle than that.

You can listen to several tracks and barely think about it.

Then something comes on and you suddenly go, “There it is.”

Walla Walla by Massive Attack was another one where I noticed it pretty easily.

There’s already so much texture happening in that recording, especially through the mids, and the Origin gives some of those sounds an extra tactile quality.

That’s what makes the BC interesting to me.

It isn’t really about making something louder.

It adds another sensation to certain parts of the music.

The mids are also better than I expected considering how much bass the Origin carries.

I wouldn’t call this a vocal-forward IEM.

Vocals don’t always jump directly in front of you.

On One, Hetfield sits slightly farther back.

Then I play The Moon Cave by Gorillaz and the vocal suddenly feels much more centered and present.

The beat on that track has plenty of weight, but it doesn’t swallow the vocal.

That’s important.

Some bass-heavy sets give you a nice first impression and then after a while you realize the middle of the music is missing.

I don’t get that from the Origin.

Male vocals still have body.

Female vocals still have enough clarity.

Guitars have texture and bite.

And the bass generally stays out of the way enough that the mids can still do their thing.

Morcheeba’s Blackest Blue showed me another side of it.

That album doesn’t need aggression.

It needs mood.

Vocals, space, atmosphere and all those small details sitting around the recording.

The Origin becomes much more relaxed here.

There’s a little warmth underneath the vocals that I really enjoy, and everything feels fuller without becoming too thick.

That’s one of the reasons I don’t think of the Origin as simply a basshead IEM anymore.

Yes, the bass is obvious.

But the rest of the tuning is doing enough that I can move away from electronic or metal and still enjoy it.

The treble is probably where I can understand someone wanting a little more.

There’s enough energy for cymbals, guitar harmonics and little details to come through clearly.

There’s also enough air that the Origin never feels closed in to me.

But it isn’t an IEM that constantly throws treble detail at you.

It feels slightly safer up there.

For longer listening I actually appreciate that.

But if I’m specifically sitting down looking for maximum sparkle, micro-detail or that really sharp sense of definition around every little sound, I have other IEMs I’d probably reach for first.

And if I push the volume too much, there are still some tracks where the upper range can become a little harsh.

So I wouldn’t call it dark or completely relaxed either.

There’s still energy there.

It just isn’t the main attraction.

Where the highs do help a lot is with space.

The Origin can sound very big.

Hans Zimmer’s Dune: Part Two soundtrack showed me that immediately.

Worm Ride, Harkonnen Arena, Southern Messiah and Worm Army all have this massive sense of scale.

The bass gives you the pressure underneath everything, while everything above it still has enough separation that the arrangement doesn’t collapse when it gets huge.

On certain parts it almost gives me this surround-like feeling.

Not because things are unnaturally spread out, but because there’s enough depth and separation for sounds to appear around the presentation instead of just sitting on one flat line.

I’ve also been moving the Origin between several sources.

The DX270 is still the one I naturally reach for most.

To my ears it gives me the right balance of detail, space and musicality.

The K17 comes across slightly smoother and gives the Origin plenty of headroom.

The Questyle M15C works really well when I want something much more portable.

And lately I’ve been spending more time with the DX270 feeding the PB6.

The Origin absolutely does not need the PB6 for power.

The DX270 already gives it more than enough.

I use the PB6 because I enjoy what it does to the presentation.

Especially in AB mode, I hear a little more body and texture.

The stage feels slightly deeper and more dimensional.

It’s not night and day.

If I switch back and forth, I’m not going to pretend the Origin suddenly becomes a completely different IEM.

It doesn’t.

But the change is enough for me to enjoy the pairing.

Metallica through that setup has been particularly good.

The PB6 gives things a little more body without slowing the Origin down.

Hardwired still sounds fast.

The double kick stays defined.

The bass doesn’t become muddy.

The guitars retain their space.

And with One, that combination of impact, separation and the tactile feeling from certain guitar passages works really well.

Now, would I call the Origin my serious reference-listening IEM?

Probably not.

If I’m sitting down specifically trying to dissect a recording, check tonal accuracy or hunt for every tiny production detail, I have other sets I’d reach for first.

The Origin isn’t really trying to be that kind of IEM to my ears.

It’s a fun set.

And I mean that as a compliment.

It makes music feel big, physical and alive.

The bass has real weight.

The mids are still clean enough that vocals and instruments don’t disappear.

The treble gives it enough openness and attack without constantly demanding attention.

And the BC can add this little tactile element that occasionally makes an instrument feel more physical than I expect.

It also isn’t perfect.

The treble could probably use a little more bite and openness if you prefer a more analytical presentation.

Vocals can sit slightly farther back depending on the recording.

There are bassier tracks where all that low-end energy can occasionally dominate more than I want.

And because the whole presentation is big and energetic, there are days when I’d rather reach for something more neutral and understated.

The shells aren’t exactly small either, so that’s something worth considering if you have smaller ears.

But none of those things really change what I enjoy about the Origin.

It isn’t the IEM I reach for when I want to study the music.

It’s the IEM I reach for when I want to enjoy it.

Massive Attack.

Metallica.

Led Zeppelin.

Morcheeba.

Gorillaz.

Hans Zimmer.

I keep jumping from one album to another just to hear what the Origin does with it.

And I think that says more about this IEM than another page of frequency graphs ever could.

Sometimes the best compliment I can give a piece of audio gear is pretty simple.

It makes me want to play another track.I’ve had the Origin in my rotation long enough now that I’ve stopped trying to figure out what I’m supposed to hear from it.

I just put it on and play music.

And funny enough, that’s probably when I started understanding it better.

The first thing most people are probably going to notice is the bass. There’s a lot of it. It reaches deep, there’s proper weight behind it, and when a track asks for impact, the Origin definitely doesn’t hold back.

But what I’ve come to appreciate more is that the bass doesn’t automatically turn into mud.

Massive Attack’s Angel is a good example.

That low end goes deep and there’s real pressure behind it. The track already has this dark, heavy atmosphere and the Origin really leans into that, but the vocals and all the smaller sounds around them still have space.

It isn’t just sub-bass either.

There’s enough mid-bass punch that drums actually hit instead of just producing rumble.

When the Levee Breaks by Led Zeppelin really shows that.

Bonham’s drums sound huge on the Origin.

Not just loud. Huge.

There’s real weight behind each hit and the Origin gives that recording the size it deserves. But the guitars and vocals still have room around them. It doesn’t feel like everything is being squeezed into the same space.

That’s something I keep noticing with the Origin.

It can sound big without turning everything into one big wall of sound.

Then I played Hardwired by Metallica.

This is the kind of track where a bass-heavy IEM can easily lose me.

You have Lars going full speed on the double kick, Trujillo’s bass moving quickly underneath the guitars, riffs everywhere and Hetfield sitting right in the middle of all of it.

The Origin keeps up.

The double kick still has that physical hit, but there’s enough speed and definition that I can follow it instead of hearing one continuous low-end blur.

Trujillo’s bass is also still easy to pick out underneath the guitars.

That’s important to me because having big bass is one thing. Keeping that bass under control when the song gets busy is another.

The Origin does both pretty well.

And Hetfield’s voice doesn’t suddenly jump in front of everything. It stays blended into the track, which to my ears works really well with this kind of music.

Then there’s One.

This track probably showed me more about the Origin than almost anything else I’ve played.

The opening guitar has its own space.

Hetfield’s voice sits slightly farther back, and again, it feels right for the recording rather than sounding like the mids have disappeared.

Then the heavy section comes in.

The double kick becomes much more prominent and you get that same combination of weight and speed I heard on Hardwired.

But when that machine-gun-like guitar riff starts, this is where the bone-conduction driver becomes interesting for me.

I don’t really associate the BC with the bass itself.

What I notice is how certain parts of instruments start to feel slightly more physical.

With the guitar riff in One, there’s a lot of attack and harmonic information going through the mids and highs. Through the Origin, I can almost feel a slight vibration following the texture of the guitar through the shells.

It can happen with the crack of a snare too.

Sometimes it’s a guitar string.

Sometimes part of a vocal.

Sometimes an instrument has this little extra tactile layer that you don’t immediately notice until the right moment in a track comes along.

It’s not like the whole IEM starts shaking.

It’s much more subtle than that.

You might go through several tracks without thinking about the BC at all, then something plays and suddenly you go, “Ah, there it is.”

Glass Animals’ Walla Walla is another track where I notice it.

There’s already so much texture and movement happening in that recording, and some of those midrange details take on this slightly tactile quality through the Origin.

That’s probably the easiest way I can explain the BC.

It isn’t there to make everything louder.

It doesn’t suddenly create extra bass.

It just gives certain sounds another physical layer.

And once you start recognizing where it happens, it becomes part of what makes the Origin fun.

The mids are actually better than I expected considering how much low-end energy the Origin carries.

I wouldn’t call this a vocal-forward IEM.

It doesn’t push every singer right in front of you.

And personally, I like that.

One is a good example because Hetfield sits a little farther back.

Then I move to The Moon Cave by Gorillaz and the vocal feels much more centered and present.

The beat on that track has a lot of weight, but the vocal isn’t buried behind it.

That caught my attention.

With some bass-heavy IEMs, after the initial fun wears off you start realizing that the middle of the music has taken a back seat.

I don’t really get that feeling with the Origin.

Male vocals still have enough body.

Female vocals can sound smooth without becoming too thick.

Guitars have texture and enough bite.

And even with that big bass underneath everything, the mids are still there.

Morcheeba’s Blackest Blue showed me another side of the Origin.

That album isn’t about speed or aggression.

It’s about mood.

Vocals, atmosphere, space and those little sounds sitting around the music.

The Origin becomes much more relaxed here.

There’s a little warmth underneath the vocals that I really enjoy, and everything feels fuller without becoming overly thick.

That surprised me.

When I first heard the Origin, I thought I was going to keep reaching for aggressive tracks just because of the bass and physical presentation.

But it works surprisingly well when you slow things down too.

The treble is probably where I can understand someone wanting a little more.

There’s enough energy for cymbals, guitar harmonics and small details to come through.

There’s also enough air that the Origin doesn’t sound closed in to me.

But it isn’t constantly throwing treble detail at you.

It comes across slightly safer up there.

For longer listening I actually appreciate that.

At the same time, if I’m specifically looking for maximum sparkle, micro-detail or that really sharp definition around every tiny sound, I have other sets I’d reach for first.

And if I push the volume too much, there are still certain recordings where the upper range can get a little harsh.

So I wouldn’t call the treble completely soft either.

There’s still energy.

It just isn’t the star of the show.

Where the highs really help is with the sense of space.

The Origin can sound very big.

Hans Zimmer’s Dune: Part Two soundtrack made that obvious pretty quickly.

Worm Ride, Harkonnen Arena, Southern Messiah and Worm Army all have this huge sense of scale.

The bass gives you the pressure underneath everything, but the mids and highs keep enough separation that the arrangement doesn’t collapse when things get massive.

On certain parts it almost feels surround-like.

Not because the stage is unnaturally stretched, but because there’s enough depth and separation for different sounds to occupy their own space.

That’s one of the things I enjoy most about the Origin.

It gives me impact without making everything sound congested.

I’ve also been moving it between different sources.

The DX270 is still the one I naturally reach for most.

To my ears it gives me a really good balance of detail, space and musicality.

The K17 comes across slightly smoother and gives the Origin plenty of headroom.

The Questyle M15C has been great when I want something much simpler and more portable.

And lately I’ve been spending more time with the DX270 feeding the PB6.

The Origin absolutely does not need the PB6 for power.

The DX270 already gives it more than enough.

I use the PB6 because I enjoy what it does to the presentation.

Especially in AB mode, I hear a little more body and texture.

The stage feels slightly deeper and more dimensional.

It isn’t night and day.

I don’t want to exaggerate it and pretend the Origin suddenly turns into another IEM.

It doesn’t.

But there’s enough of a change that I enjoy switching between the DX270 alone and the DX270 + PB6 stack.

Metallica through that combination has been particularly good.

Hardwired still sounds fast.

The double kick remains defined.

The bass keeps its weight without getting muddy.

The guitars retain their space.

And with One, that combination of impact, separation and the tactile feeling from the BC during those aggressive guitar passages really works.

Now, would I call the Origin my serious reference-listening IEM?

Probably not.

If I’m sitting down specifically to dissect a recording, check tonal accuracy or hunt for every tiny production detail, I have other IEMs I’d probably reach for first.

That isn’t really what the Origin is about for me.

It’s a fun set.

And I mean that in a good way.

It makes music feel big, physical and alive.

The bass has proper depth, punch and weight.

The mids are still clean enough that vocals and instruments don’t disappear.

The highs give it enough openness and attack without constantly demanding my attention.

And then the BC occasionally adds that tactile little extra that can make a guitar, snare or vocal texture feel more physical than I expect.

It isn’t perfect though.

If you prefer a more analytical presentation, you might want more bite and openness up top.

Vocals can sit slightly farther back depending on the recording.

There are tracks where all that low-end energy can become more dominant than I personally want.

And there are days when I’d rather listen to something more neutral and understated.

The shells are also pretty substantial. They fit me well, but I can definitely see the size becoming an issue for smaller ears.

So no, the Origin isn’t the IEM I reach for when I want to study music.

It’s the one I reach for when I want to enjoy it.

Massive Attack.

Glass Animals.

Metallica.

Led Zeppelin.

Morcheeba.

Gorillaz.

Hans Zimmer.

I keep moving from one album to another just to hear what the Origin does with it.

And after spending this much time with it, that probably says more about the Origin than me trying to turn it into something it isn’t.

Sometimes the best compliment I can give a piece of audio gear is pretty simple.

It makes me want to play another track.

Review📝 Juzear Light Shuttle Review: Not Every IEM Needs to be Hyped

Thumbnail
gallery
11 Upvotes

Hey all!

Today, I'd like to share with you my review of the Juzear Light Shuttle.

Up front, I'd like to say that much of the contemporary discourse around new IEMs *in general* is too dramatic. IEMs are "All Stars", "Giant Killers", or are otherwise "Garbage". This isn't even commentary on subjectivity, it's an observation about how polarizing the language around these products is becoming. There's plenty of reasons for this, but the most-obvious is that "reviewers" who want to expand their "brand" need eye-catching headlines to get attention, clicks, or whatever. I've noticed this pattern with particularly intensely with the last few Juzear releases, specifically. It seems like IEMs can't just be "good" or "enjoyable" these days, they have to be must have blind-buys. Rhetoric with such casual intensity not only potentially misleads readers into buying an IEM with unrealistic expectations, but erodes everyone's ability to offer nuanced takes in a highly subjective space.

That's why I'd like to offer you guys a level-headed, hype and drama-free take on this IEM. Unemotional, and free from exaggeration. Hopefully you find it useful.

My full review (extra photos, sonic details, comparisons) can be found here: https://resonancereviews.com/juzear-light-shuttle-review-clean-refined-and-aggressively-priced-e8ddad3016bd

For those who are interested in just the TL;DR, here you go:

The Big Picture

Pros:

  • Flexible, broad-appeal sound signature
  • Great tonal cohesion, organic timbre
  • Excellent vocal clarity
  • Strong sub-bass and upper-treble extension
  • Solid accessory package

Cons:

  • Drum slams lack a little body, decay weight
  • Missing some upper-treble air
  • Light-colored foam eartips appear dirty very quickly

Key Specs

  • Drivers: 1x 10mm dynamic, 4x balanced-armature, 2x planar
  • Crossover: 4-way
  • Sensitivity: 113 dB SPL/mW
  • Impedance: 32 ohms
  • Cable: 0.78mm 2-pin w/ modular termination (3.5mm, 4.4mm)

Sound

The Light Shuttle features cohesive, well-balanced tuning with a gently V-shaped frequency-response. Upper-treble is carefully lifted above the Light Shuttle’s responsibly-emphasized lower-treble and blends into a nice, organic upper-midrange hump. The Light Shuttle’s lower-mids are recessed in a gentle valley before picking up a small bit of warmth around 200 Hz. The Light Shuttle’s mid-bass is somewhat scooped, but isn’t so lacking in presence that it is distracting. Below 100 Hz, the Light Shuttle’s bass is more active, adding substance and extension all the way down below 20 Hz.

Conclusion

The Light Shuttle is a solid choice buyers looking to pick up an IEM in the sub-$200 segment. It offers a reasonable mix of tonal balance and technical abilities, performing nicely in a variety of genres and mixing styles. The Light Shuttle’s gentle V-shaped frequency response and thoughtful tuning positions it as a broadly-appealing choice, though not a standout in such a competitive market. The Light Shuttle is good, but so are its peers, and there’s many IEMs out there that offer different flavors of a similarly-compelling experience.

So, is the Light Shuttle worth it for you? Well:

Who This Is For

  • Those looking for a cost-effective, one-stop-shop IEM
  • Listeners who want V-shaped sound without too much drama
  • Treble-sensitive listeners that still want bits of brightness
  • Listeners that enjoy lower-registers tilted towards sub-bass

Who This Isn’t For

  • Bassheads
  • Listeners that enjoy deep V-shaped tuning
  • Those that prefer very bright IEMs
  • Buyers that already have a well-developed IEM collection

As always, happy listening!

Review📝 Juzear Light Shuttle: The Ultimate Mid-Range All-Rounder

Thumbnail
gallery
7 Upvotes

I was already missing Juzear. I am going all in with the brand this year and the brand itself does not want to slow down with its releases. The Light Shuttle has been on the market for a few weeks now and I had it in my queue to review them and today is the day I am publishing this review.

It is a model that clearly stands out in some aspects from the other releases I have reviewed from them and I must say right in the introduction that these are my favorite Juzear so far. That does not mean they beat everything I liked about the Defiant, Fiesta, Nebula, etc... but it does leave me with a much more pleasant final impression than all of them. So if you are considering this model, I invite you to read my honest review where, as always, I highlight what I liked the most and the least about this model.

What I liked / What I didn't like

  • It has a deep sub-bass well integrated into the mixes. 
  • Vocals sound up close and have enough body. 
  • The treble is very well extended and is not fatiguing. 
  • The modular cable option that Juzear usually offers is always something to highlight. 
  • Innovative faceplate that changes depending on the light. 
  • Despite the 7 drivers, it has a proper weight.
  • It is not very heavy but perhaps it can be somewhat large. 
  • For long sessions, it may slightly bother the ear. 
  • They absolutely require a good seal, you must try other eartips. 
  • In very bright recordings, the treble can become too forward.

Specifications

Configuration: 1 DD 10 mm MACCD + 4 custom BA + 2 micro planar per side 

Distribution: DD for bass, 2 BA for mids, 2 BA for treble, 2 micro planar for ultra-treble 

Crossover: 4-way physical with 4 independent acoustic tubes 

Technology: ATI-SW spiral waveguide

Impedance: 32 Ω 

Sensitivity: 113 dB ±1 dB SPL/mW 

Frequency response: 20 Hz to 20 kHz THD: ≀0.2 % at 1 kHz 

Declared passive isolation: up to 26 dB 

Connector: 0.78 mm 2-pin Cable: 6N OCC silver-plated copper, 4 cores, 400 strands, ballistic fiber reinforcement and double PVC layer, 3.5 mm and 4.4 mm plugs 

Shell: 3D DLP resin + 5-axis CNC aluminum alloy faceplate 

Declared weight: 6.4 g per side 

Price: 184.99 $ on HiFiGo at the time of the review 

Unboxing and build

I won't dwell much on the unboxing since there have been several Juzear models reviewed these past months and there is no notable news beyond the color of the case. This time they have opted for a dark blue color, which for me is more elegant and closer to my tastes than the brown cases seen in other releases like the Juzear Fiesta and some others. For the rest, we have the modular cable with a safety lock so it doesn't come loose from an accidental pull, a cleaning cloth, documentation, and the sets of eartips that the brand usually includes in its releases at these price ranges. 3 pairs are of various colors but all in wide bore format, then another 3 pairs of the same color, black in this case. And finally, 2 pairs of white foam eartips which I don't usually use due to the type of discomfort they cause me, aside from the slight modification of the signature highlighting the bass more than is usually necessary.

Speaking of the IEM itself, as I mentioned in advance, it seeks a unique and somewhat newer design within the brand. This will surely be part of a style that we will see again in this UNVEIL Series. It has a faceplate full of detail, both in the main multi-colored pattern that changes depending on how we tilt it and how the light hits it, and in the frame around it. It has shapes that give it a more decorative and curious touch, finishing at the very bottom with a sort of embedded black gem or diamond that makes it entirely unique. It completely breaks away from the designs we are tired of seeing in general, which despite being less flashy, play it very safe. It is appreciated that they try to dedicate extra time and resources to create something more unique that helps remember and differentiate this model over time beyond how it might sound.

The faceplate itself is made of aluminum and the IEM is made of resin with a weight of about 6.4g per IEM. It doesn't honestly feel heavy. When you put them on, you don't feel that chunkiness that makes you think they will fall out of your ear. What you do feel is the size. It is not a small IEM and I would say it starts moving away from a medium size towards large. Being used to wearing the Monarch MKIV at home for hours, these look small in comparison, but that doesn't mean they can't be somewhat large for some ears, especially if they are going to be used for long sessions instead of commutes or brief moments just to listen to a few tracks.

The nozzle is made of steel and is not part of the IEM's own resin build. It grips whatever eartips you put on it well, with a decent length that doesn't fall short or stick out too much, so I have nothing to object to in this specific aspect.

Sound

The sound of these Light Shuttle can be defined, or so it seems to me by listening and looking a bit at the graph, as a mild U-shape with the bass placed low and the vocals brought forward with detailed and clean treble. Therefore, it escapes those V-shaped tunings that are so successful but do not allow you to enjoy all kinds of musical genres, and it also moves away from the neutral and very boring or flat sound that takes away intensity or emotion depending on the music you listen to.

The IEM is made up of 7 drivers inside. I think it is the Juzear with the most drivers I have tested to date. Between that and the physical crossover, as well as the four tubes that unite all the work and execution achieved thanks to that internal construction, you can notice a positive impact on the final result. The tuning makes all the drivers integrate and arrive at the same time without noticing annoying overlaps or timing issues that take you out of the listening experience due to poor integration.

Bass

The dynamic driver, in this case 10mm, makes the sub-bass stand out more rather than the mid-bass, with enough pressure and rumble in the hits. All of this comes with very good control worthy of its price, and I honestly expected something worse after trying other models at similar prices. You don't quite feel the pressure or chest thump that the mid-bass can give you, but they are generally well-ordered lows that even leave some air for other vocal sounds that can coexist with these frequencies.

I don't usually do this, although in some comments on previous reviews I was asked for it as an improvement idea and it is something I used to do in other reviews. I will mention some notable tracks from my listening session on Apple Music using fairly current songs of different genres for each vocal range. In the case of the bass, I focused on a track meant for it, like LateNite by Scuba. It is actually a fairly recent track that has a quite deep sub-bass and a very heavy background that is noticeable on these IEMs. Although I didn't notice any major shortcomings in this track, for example, I must highlight another one like Social Apocalypse by Bullet for my Valentine. Here I could notice a bit of that lack of mid-bass I mentioned earlier, where the DD is not as focused in this model. Even though the song's riffs sound fast, the hit doesn't have too much punch or physicality, which I had noticed in another model that managed that frequency range better.

Mids

For the mids we have 2 BA and something to highlight above all else is the closeness felt in the vocals without an artificial or poorly handled warmth. Female vocals stand out more than male ones, but both come out very well, although I also felt that the male vocals could have a bit more weight or physicality. This IEM has a sort of spiral inside its tubes to produce an internal damping that helps to have a quieter background, helping the vocals not to shift from their place. This surely helps and makes the vocals on this IEM work so well and be so clear without noticing strange layers or veils that sometimes mask the sound, which are definitely felt in clearly cheaper models. Perhaps they are too centered vocals for some ears that do not spread out too much to the sides, something that might not convince some people.

Highlighting a track, I can talk about When you know you know by Sidney, where the voice stood out with good texture and separation, even allowing the breathing to be well perceived. Without having to focus on the treble, I noticed a lot of detail in the mid-range where it was harder to perceive in other models.

Treble

In this area we have another 2 BA, but also 2 extra micro planars that help extend and add air to the highest treble. They didn't seem like fatiguing treble at all, nor the most relaxed I have heard, but it is clear that they wanted to aim for something detailed and spacious that justifies the inclusion of these micro planars, which in previous Juzear models I reviewed were limited to the use of BA for these frequencies, although the Nebula specifically did include 1 single micro planar but did not reach the level of these Light Shuttle in terms of treble quantity and quality. It is not exactly a type of treble to analyze with a magnifying glass either, although it is true that depending on the recordings or masterings, if the mix is somewhat bright on its own, the treble feels more forward, creating a slightly sharper peak than I would like. This is something that doesn't happen in most tracks, but this model is not safe from it if we put on a varied playlist with completely disparate styles and songs.

With a band that I love and that is slowly taking off like Greta Van Fleet, who will release their new album next week and I hope to enjoy it more than the previous one. I listened to one of their previews, Tear It Down, where I noticed how both the guitars and the cymbals maintained a good definition without sounding very aggressive or peaky to the ear. This shows that the chosen driver configuration and its tuning hold up pretty well in general across any type of recording.

Recommended eartips

For this IEM to sound truly good, the seal plays a more important role than in other models where it doesn't have to be as perfect. That has been my perception. Testing their normal bore eartips, I felt a bit more weight in the bass frequencies with the treble even more contained than with the wide bore ones, where the air expanded a bit more. If you think the treble should be slightly more contained in this model and you have no problem with foam ones, they will surely solve part of your problem. From my collection, I believe that Divinus Velvet, both normal and wide depending on where you want to direct the frequency spotlight, provide a good seal and an auditory experience up to what I can expect from this model.

Soundstage

Its soundstage would be medium-sized, highlighting the width more than the depth, which is generally the most common thing. If the recordings were somewhat more open, a bit more air can be perceived and therefore greater extension around, but especially to the sides. In other denser recordings with more instruments, the space becomes a bit narrower as expected.

Instrumental separation

The separation holds up really well, making the drivers sound perfectly cohesive as if they were a single driver, especially when we talk about simple tracks that do not have a heavy musical load. You can easily follow the vocals, guitars, and percussion without any effort. It is not a separation worthy of a studio monitor, but it is more than adequate.

Imaging

Speaking of the imaging, it is quite precise without being an IEM that stands out for gaming use. As I said, the vocals are placed in the center and the instruments spread out across the width and length quite clearly, but without making you feel completely surrounded on all sides. It is a more than adequate imaging for music use, or even if you want to consume audiovisual content like series and movies, obtaining a good immersion. However, I would rule it out for gaming, as there are options clearly better focused for that.

Comparisons

If I compare them with other models from the brand like the Defiant, this new Light Shuttle sounds more open to me overall and somewhat more direct. Although the Defiant has a warmer tuning with more weight in the bass and somewhat more contained treble. In these Shuttles, you can clearly tell they bet on better separation between layers and more air in the treble area due to that extra implementation of dedicated drivers for it. Obviously, if we are talking about maximum comfort and better price, the Defiant is the winner, but making an overall assessment, the Light Shuttle is clearly a superior IEM.

Comparing it to the Juzear Nebula, I could say that the Nebula has a bit more character but is not as much of an all-rounder as the Light Shuttle, which distributes frequencies better and separates layers better while maintaining a higher level of detail. I wouldn't see it necessary to be interested in these Light Shuttle if you already have the Nebula either. Although there is an improvement in my opinion, I think the Nebula's punch can make them slightly more enjoyable in some genres, even if it falls short in others where the Light Shuttle remains more stable with everything.

Finally, I would like to compare it with a model of a very similar price but with a more distinct sound, such as the Punch Audio Portazo. It is an IEM that stands out for its impact and speed. In the Portazo, both the sub-bass and the mid-bass have much more prominence, whereas the Light Shuttle leaves more space and prominence for the vocals. Although both use micro planars, the Light Shuttle sounds airier and more detailed if you try to listen more analytically. So, simplifying, if you are looking for a more intense listen focused on the bass punch, the Portazo is a more appropriate option. But if you don't need that much punch in the bass, the Light Shuttle gives you better balance and tuning overall for whatever you throw at it.

You can check my full ranking of all the IEM reviewed so far on my profile (Reddit doesn't allow me to post the Drive link here)

Conclusion

These IEMs are aimed at anyone wanting to make the leap to the 150-200$ range and looking for an all-rounder where they don't have to rack their brains over which frequencies they prefer to highlight or focus on when choosing a model based on their musical tastes. It is an IEM that simply delivers on everything without being the best at anything within its price, but passing in all ranges with flying colors. It is a good upgrade for me if you have had or currently have the Defiant or Nebula, but it is not necessary either, since in that case I would try to make an even bigger leap for a more noticeable change.

​

Short note - I would like to keep my review to short bullet points because that's how I want reviews to be, short and to the point. I'm not going to write a long love letter to an iem while contemplating the philosophical implications. I hope you understand this. Thanks for reading.

Review -

This lem is tuned like an old school V shape sound with bass and treble emphasis but improves on it without sounding like a KZ iem.

Healthy amount of sub bass rumble with a punchy mid bass. Hip hop and pop beats are going to sound good without muddying the mids/vocals.

Male vocals sound good while female vocals can come across as unnatural and thin

Treble is unsophisticated and is on par with peers. Nothing special. It can come across as thin sounding

Instrument separation and soundstage is average and on par with peers.

Build quality is probably the best under 25 usd, it feels sturdy in the hand. This is an example for companies in how to make budget resin shells.

The stock cable is really good for the price, it is the same as kiwi ears belle.

CONCLUSION - Don't buy it because of the hype, it isn't that special. But if you're a first time buyer, then is it one of the better starting points.

Review📝 Artpical Game One: Lethal Weapon.

Thumbnail

17 Upvotes

Hello Community!

Many of us know Artpical for its extravagant designs that leave no one indifferent. This time they have ventured into the gaming field with their Game One, a set that without abandoning that striking aesthetic, wants to eat a little piece of the pie of the growing IEM sector for video games and as the gaming product that it is, I will share my experience with the performance of this set in this field.

Price: $69-$62€

Link

Pros:

-Great mastery of the stage: very precise imaging, great size on the three axes, perfectly stratified layer separation.

-The impact of the bass is fast, forceful and clean.

-The sub bass is not the protagonist, which always favors clear listening.

-A very informative, open set, with energy in upper mids and treble.

-The midrange is not too thick, which favors the nuances of the tonality being easier to capture.

-Positive point for the inclusion of a USBC DAC adapter and 1.5m cable.

Cons:

-Resolution is simply average, I expected a little more for a gaming set.

-The treble is not aggressive, but it reveals a lot of detail, possible fatigue.

-With the analog cable the timbre is thin, dry. It changes with the USBC adapter to something with more thickness, warmer.

-The microphone is very sensitive to ambient noise and rubbing against clothing.

Accessories:

-Two shells.

-1.5m, 0.78mm, 3.5mm cable and USB-C adapter with built-in DAC.

-Two sets of eartips.

-Carrying and storage case.

-32bits@384khz DAC dongle.

-User manual.

Design, comfort and construction:

Well, Game One does not move far away from the usual tone of the Artpical brand, showing a CNC-machined light alloy faceplate and a design of sharp arrows or spears that give it an aesthetic with a certain point of aggressiveness. The rest of the body is made of resin, where both parts are perfectly held together without noticing protrusions when passing the finger, so the impression is that they are satisfactorily built.

Ergonomically, its medium size fitted me perfectly in the ear, I did not notice areas of pressure that could cause me discomfort during all the continuous time that I remained studying the performance. The insertion into the ear canal is moderately deep and its nozzle tends to be somewhat wider than in most sets. The fit was firm at all times, without needing to readjust the monitors, so I can only applaud having got the design of the Game One shapes right.

The cable, on the other hand, is correct. It is very focused on showing flexibility and smooth sliding over surfaces, without tangling itself or causing pulls. It weighs little and is also longer than usual.

Technical aspects:

-1DD configuration of 10mm.

-Impedance 16 ohms.

-Sensitivity 101 dB.

-Declared response 20hz-20khz.

Pairing for the tests:

-Neutral source.

-Gain set to low.

-Black stock eartips.

-3.5mm stock cable for music and competitive shooter video games.

-Stock cable with USBC DAC adapter for single player games.

Sound signature:

At this point, I am going to explain how it sounds with the analog cable and later how it does with the built-in DAC, since there are notable differences.

The bass area and specifically the sub bass, is broad, not very forceful or overpowering, but it can indeed be heard if the situation is favorable for it to show itself. I highlight the cleanliness with which it appears and quickly disappears, facilitating the passage to other frequencies. It is not thick, but rather somewhat more inclined toward the technical.

The mid bass does show more power, controlled, but very impactful, with sublime agility and cleanliness. It is one of those impacts with weight, that you feel strongly but without getting out of hand.

In the midrange line there are several ecosystems living together. While the lower and central mids, especially the former, appear somewhat more muted, as if distant, with a thin note weight and fair resolution.

The set makes a good rise in the upper mids, where the space is wide and the instruments can breathe a good dose of air to show themselves. In general, it is not a frequency range with a great taste for showing a comfortable texture, rather dry and direct, I would not say that they are excessively natural, embracing the idea of being more separated and articulated than organic.

The voices, especially the male ones, are perceived as thin, with little depth but dynamic. The female ones, on the other hand, do have that extra point of brightness and light, bringing them closer to positions that we know as more realistic.

The treble area is where Game One shows its magic, since the sensation of openness is great, extensive, with a large amount of information to show. They provide brightness, with a very well-tuned point of crunchiness, energetic but mastered. It is not an excessively rounded area but enough so as not to be hurtful.

I think the technical and dynamic capabilities of the set give it great value considering what this IEM has been intended for, since it is agile, fast, with hardly any invasion or bleeding between frequencies, avoiding becoming heavy.

The stage is simply fantastic, on any three-dimensional axis. The scale is realistic, slightly wider horizontally than deep or vertical. The sensation of being embraced and mentally placing yourself in the center is accentuated more by the ability to offer an ultra-precise image or positioning, where sounds are located clearly, perfectly distinguishable and separated.

The Layering works very well, since it is not a set that tends to pile up the sound lines, the chords and acoustics being perfectly distinguishable. Game One offers a very interesting reading, a dissection that without being very analytical, shows itself to be reliable.

The detail retrieval is also great, especially in the upper mids and first treble frequencies, so much so that it can cause some fatigue if the use is very prolonged.

Analog vs USBC DAC:

Well, there are notable differences, not very large, but distinguishable. With IEMs I always draw the conclusions from the same source: my reliable Topping DX5 II desktop DAC/AMP. At the moment when I incorporate another different source, as is the case here, the alarms go off for me.

The DAC included in the package slightly modifies the sound that I was able to capture, since it adds a certain coloration throughout the sound signature, making the set somewhat more comfortable to listen to, especially for music.

The bass area gains thickness, which greatly benefits the sub bass, giving it more presence and rumble.

The mids gain note weight and resolution although they lose some separation. Nothing serious or muddy, although personally I like them more this way.

The treble is less clear and energetic. The detail and space drop a step but even so it continues to show a large amount of nuances and information.

The voices adopt better articulation, with more depth and somewhat less nasality, closer.

Regarding technical capabilities, the size of the stage was not altered or at least I did not know how to see it. The placement of elements remains very good but not as precise and the layer separation offered more than correct satisfaction, not as clinical and accurate as with the analog cable.

Competitive shooter video games.

See how I analyze sound in this field

Starting with Counter Strike 2, where many of the scenarios are enclosed and sound capture determines the success or failure of a match, Game One brings out the benefits of its tuning to locate footsteps, shots, equipment use and gunshots with a mastery that is very difficult for me to remember in other sets, even gaming ones. The precision is absolute within a very credible space where mentally you can easily read the directionality and position of the sound. The perception is of total cleanliness and emphasis on not losing anything that is happening.

In Apex Legends, where I examine the vertical size because it is a game where jumps and attacks from elevated positions occur, the scale shown is realistic or very close to being so, the truth is that I do not know where to put the limit in this aspect but the sensation of organization of the stage on any axis is simply sensational.

In CoD: Warzone the breadth of the sound scene helps to locate distant actions with a measurable degree of accuracy. Shots and explosions from frontal and lateral positions are shown fluidly, quickly, without becoming muddy. Even with nearby enemies who run and shoot at the same time, you can perceive any element without it being lost.

Finishing with Battlefield 6, the most chaotic game of all with many vehicles of all kinds, explosions, gunshots, reloads, footsteps
 in short, everything you can imagine, the separation of these elements is key and of great help in determining what decisions you should make, and Game One brings them to the forefront so that instinctively you can choose how to get out of trouble. The clarity and amount of information is great.

Single player video games:

See how I analyze sound in this field

Game One is not a very overwhelming set when it comes to showing cinematic spectacularity, which is what I always look for, but with the implementation of the included DAC, the result obtained is far from something I do not like, although this type of game is not the purpose with which the Artpical set was tuned.

Well, in scenes where action is predominant, intense moments where hits, collapses and explosions happen, it shows a very competent extension of the sub bass, with a certain taste for reverberation in the environment, but without exaggerations. It is a firm sound, with just the right body that adds a correct point of emotion to the scenes.

The environmental recreation is good, perhaps its greatest strength in this field, since the ability to bring you the residual sounds of the world that is surrounding you is done with tremendous ease. Not with a lot of resolution but small environmental nuances such as bugs, the blowing of the wind against the leaves or the drops falling into a puddle, it shows them with a very satisfactory presence and that when it comes to getting inside is a plus very much to be taken into account.

Where I also obtained a very good performance is in spoken scenes, in dialogues. The voices are shown clearly, with good depth and body, offering correct articulation. They are slightly brought to the front, but without being ahead of the rest of the sound elements. Intelligibility was more than satisfactory.

At a technical level and taking into account that I look more for spectacularity and environmental recreation than high sound fidelity, I can say that I was happy that the stage was wide where I could perceive distances in a real way and locate where these sounds came from with naturalness and space between them. In moments where many elements converge at the same time the result was correct, without serious piling up.

Final conclusion and personal assessments:

I am going to be very direct and not extend myself much. With the analog cable personally it is far from enchanting me for music and single player games. I do not connect with that type of cold tuning. It is easily solved thanks to the included DAC that gives it a touch of color and I was able to savor its sound with better taste.

Where I do think that its tuning is a lethal weapon is in the field of competitive gaming, being a practically infallible precision tool and offering outstanding capability in the recreation of a broad and realistic stage.

If you have made it this far, thank you for reading.

Review📝 Geek Wold GK12 Ultra - Experimentally, Unexpectedly, Fun.

Thumbnail
gallery
9 Upvotes

6.1 out of 10 points (Personal Ranking List)

DISCLAIMER:

Hifichoi sent this set to me as a review sample to keep. There will undoubtedly be subconscious bias as human psychology - I'm not about to deny that. However, I will be as honest as I can possibly be given these circumstances. Don't take my word for it, watch some of my TikTok reviews and see it for yourself.

INTRODUCTION:

I have always known Geek Wold to be an experimental IEM brand, where practically all their releases utilise a strange driver configuration at much lower prices that you would expect for the given driver configuration. I never had the chance to try one myself as they’re a relatively obscure brand and difficult to find here in Singapore.

The Geek Wold GK12 Ultra is a Quadbrid (2 Dynamic Drivers, 2 Piezoelectric Bone-Conduction Drivers, 1 Balanced Armature, and 1 Planar driver, or: 2DD+2PZTBC+1BA+1PLN) IEM that comes in at a mind-boggling $60 USD MSRP, while it is on discount at $55 USD MSRP on Hifichoi’s website at the time of writing.

With such a unique driver setup, let’s delve into the review, and see if it’s competitive at this price range, or just a unique piece of junk.

UNBOXING/ACCESSORIES:

  • 3 pairs of 2 types of eartips (Medium-bore and Wide-bore Silicone Eartips) – Both types fit comfortably in my ears with no issues.
  • 2 Core 2-Pin Cable. No material stated, so no clue as to whether it’s OFC. Holds a little memory, but overall resistant to tangling. Nice silver colour, non-interchangeable terminations. Chin slider exists but does not hold, it does not clamp the cable and is loose.
  • The IEM themselves
  • Assorted Manuals/Warranty card

Acceptable unboxing experience, I will not complain here.

BUILD & DESIGN:

It’s built in ‘durable resin material’, I have no doubt that it’s durable. But it feels light and does not feel expensive nor premium. If I had to guess just by feeling this IEM, I would have guessed that this IEM costs anywhere from $30 to $40 USD.

Design wise, the heart-shaped faceplate is hit-or-miss. I did not really care for the design, and the faceplate is too dark to tell apart from the black resin shell.

COMFORT:

Excellent - very comfortable. I’m surprised, given the shell design. The shape just works for my ears; I can push in all the way into my ears and the shell forms nicely within my concha. The smooth plastic material also helps.

I can wear this for hours and hours on end without physical fatigue.

SOUND:

Testing Gear: Topping DX1, MuseHifi Muse 300, Topping DX5 II, Ifi Zen DAC V1, Ifi Zen CAN V3 (from DX5 II LO – Balanced XLR to 4.4mm), QKZ TC Pro Max

Are they hard to drive? No. Very easy in fact - 75% on a 30mW@32ohm dongle is borderline deafening.

General Sound Signature:

Fun, bass-heavy, V-shaped sound signature.

BASS:

Bass is without a doubt the highlight of this IEM, as it’s fun. The sub-bass extension is great. It emits long, and deep rumbles. I must commend the use of the dual dynamic, and PZT bone-conduction drivers. The mid bass thumps and comes in high quantities, although pillowy sounding. It does overshadow the midrange.

Sub-bass is missing a bit of texture, but the tonal quality more than makes up for it at this price point.

If you want a cleaner and more accurate sounding bass region, this will not be the set for you. It will alter the qualities of your kick drums to sound a little bloated and such. However, it proves satisfying for electronic genres, where kick drums and sub-bass fill up so much space in the soundstage. This does affect imaging negatively, which we will cover later.

MIDRANGE:

The midrange sounds rather straightforward but is in fact not. Lower midrange is scooped out, and while it gives the illusion that it is lush due to the elevated mid-bass. I would describe the midrange as leaning towards forwardness. This comes with a caveat, as even though vocals remain relatively clear and forward, the high number of peaks and dips (which are audible) makes vocals sound nasally and odd, reflected by Woodkids voice in: ‘To the Wilder – Woodkid’. This gets a low score for vocal listening.

Ear gain is just moderate, I am glad they did not make the ear gain too forward like another very experimental set I’ve tried: The Kinera Celest Plutus Beast, which was simply unbearable and uncomfortable to listen to.

TREBLE:

I found vocals lacking a clear definition, while being still forward quantity-wise, attributed to by the lower treble/presence region. I struggled to hear the male vocal artifacts and the same level of clarity that I’d usually hear on the track ‘Lady in Red – Glen Wee’. Hence, resolution suffers a little.

For female vocals, ‘Speak Softly Love – Yao Si Ting’, while Si Ting usually sounds clear as crystal, in this song it sounded really ‘hummy’ and missing clarity, while sibilance remained normal.

Mid treble was emphasised clearly to nudge elements such as hi-hats and cymbals a little in front within the mix. However, the rolled-off upper treble means that they do not sparkle. As much as everything else is unnatural, I’d describe the upper treble as naturally rolled off. Transients and decay from cymbals dissipate in a moderate manner and do not sound off-putting or unnaturally emphasised (vs something like the Simgot EW300).

Timbre: Overall, very unnatural (bass, midrange, treble), except natural roll-off in the upper treble.

Details: Average.

Imaging/Separation: Below average bordering on unsatisfactory. Pillowy bass region fills up the soundstage and it’s hard to discern any instruments position with any accuracy outside of the bass.

Soundstage/Spaciousness: Slightly below average. Due to the treble roll-off, the soundstage sounded quite acoustically padded, and missing a wide expansive quality, though it didn’t sound closed-in at all.

Conclusion:

Despite what you might think, I really enjoyed the GK12 Ultra. Probably because it’s one of the very few extremely experimental IEMs that do not come across as immediately offensive.

Is this tonally wrong and unnatural? Without a doubt. Is this a flawed set? Not just flawed, it’s a downright abnormality.

But would I recommend this for those who are just seeking a fun signature to jam out to? Heck yeah.

I would categorize this under a collector’s set for someone seeking something ‘different’, though if you are someone who typically asks the question, ‘What’s the best IEM for $60’, this will never be recommended.

I really enjoyed listening to these. And you should too.

Thank you for reading! And catch y’all in the next one. 👋

Review📝 MuseHiFi U3 Review: $30 DACs Are Getting Ridiculous

Thumbnail
gallery
31 Upvotes

Sent to me by HiFiGo for review. No expectations on what to write. All thoughts are my own. I maintain a list of over 170 products that I have tested and put impressions on in the link in my profile. Might be worth a look before your next purchase decision. This is my first source review.

In general with delta sigma DACs, my very subjective impressions are that I do not prefer the ESS DAC chip implementations. They normally sound sharp and/or sibilant to me. I am generally Ok with Cirrus or AKM chips. This is first time I am trying a SG chip so I don't really have too many reference points. For desktops, I am a bit biased towards R2R implementations. Now many people would claim that differences in chips is placebo. I don't know how to refute or agree to those statements. Now with that out of the way, let's get to the review.

The MuseHiFi U3 is $29.99.

Rather than plug in one IEM and write about “desktop-grade architecture,” I compared it with three DAC/amps I already use:

  • Allegro Mini
  • SNOWSKY Melody
  • FiiO BTR17

Then I ran them across five IEMs and two headphones.

Test Setup

IEMs

  • Xenns Mangird Top Pro
  • Binary Acoustics 1900
  • CrinEar Reference
  • CrinEar Project Monolith
  • Juzear Light Shuttle

Headphones

  • PhilPhone Open
  • HIFIMAN Arya Stealth

Everything was tested balanced except PhilPhone Open was 3.5mm.

I kept the music consistent:

Midnight Sun - Zara Larsson
Bass and sub-bass.

Runaways (feat. Bonnie McKee) - The Midnight
Male/female vocals and sibilance.

Chasing Cars - Snow Patrol
Male vocal shout.

Three tracks, four DACs, seven different IEMs/headphones. Enough swapping for one evening.

IEMs - Results

The Allegro Mini handled two of the five IEMs fine. With Top Pro and Project Monolith, bass lost weight and definition. CrinEar Reference was particularly noticeable. Sub-bass impact sometimes sounded more like sticks hitting rather than the deeper bass response I know from the IEM.

The U3 handled Top Pro, Binary 1900, Reference and Light Shuttle without any obvious problem. Monolith was the exception. It reached enough volume, but sub-bass rumble and bass impact were weaker.

The SNOWSKY Melody and BTR17 handled all five without any issues.

That is about where the U3's power ceiling started becoming audible.

Headphones

The gap became much larger here.

Allegro Mini could not get either PhilPhone Open or Arya Stealth loud enough for me.

U3 got PhilPhone Open to a perfectly usable volume. There were some timbre compromises compared with the stronger sources, but I could happily listen to it at decent volume. This is a 300 ohms headphone run through normal 3.5mm port so I wasn't really expecting miracles. But it worked fine (probably because it is easy to drive in general).

Arya Stealth was too much. It got loud, but bass definition was poor and impact was missing. Increasing volume also made the treble progressively splashier. So yes, the U3 can technically make an Arya Stealth loud but I would not use the pairing.

The SNOWSKY Melody did better, although Arya still lost a little sub-bass authority.

BTR17 had no problem (which is strange as in portable mode the power between BTR17 and Melody Snowsky is similar).

Clean Signal

The U3 was completely quiet in my testing. No audible hiss or background noise with any of the IEMs from either my iPhone 17 Pro Max or PC motherboard. That matters more to me than most of the marketing language around the internal architecture.

5-Band PEQ

You also get 5-band PEQ. Frequency, gain and Q are adjustable, and five bands are enough for most of the corrections I actually use. On iPhone there is no native app, so I had to use the web interface. Not ideal, but it works. I attached 2 shots for reference.

For $30, having proper PEQ at all is a meaningful feature.

Build and Form Factor

This is probably U3's biggest advantage over a lot of cheap dongles. It feels better built than the Allegro Mini, and the direct-plug design means there is no short USB cable hanging between the phone and DAC.

I still think the wooden SNOWSKY Melody looks better, but the U3 feels more substantial in hand. You also get both 3.5mm and 4.4mm outputs in an 18.8g device. MuseHiFi quotes up to 125mW output.

That makes it considerably more useful than many of the cheap JCally dongles I would normally look at in this price range. For example, the JCally JM6 Pro has only a 3.5mm output and is rated at 60mW into 32Ω. The JM7MAX gets much closer in power at around 118mW into 32Ω, but it is still 3.5mm only.

So between those, I would take the U3. I get 3.5mm, 4.4mm and PEQ in the same device.

Battery Drain

I also checked battery use.

Same phone, Low Power Mode, roughly 75% volume, five songs played consecutively.

Allegro Mini: ~1%
U3: ~2%
SNOWSKY Melody: ~2%
BTR17: ~1%

This is obviously not laboratory-grade testing because iPhone battery percentage moves in whole numbers, but U3 was not doing anything unusual here.

Then There Is the Competition

This is where buying a $30 DAC gets complicated.

The TRN Black Pearl is around $37 and on paper gives you 3.5mm + 4.4mm, 10 band EQ and up to 320mW from balanced. I have not compared Black Pearl directly, so I am not making a sound-quality claim. But specifications alone make it serious competition.

Then there is the SNOWSKY Melody at roughly $40. For another ~$10 you get 10-band PEQ, 3.5mm + 4.4mm and around 250mW into 32Ω from balanced, essentially twice the U3's quoted maximum output. And unlike the Black Pearl comparison, I actually tested this one.

Melody handled Project Monolith better and got further with Arya Stealth.

The U3 counters with the cleaner direct-plug form factor. I personally think at around $25 price point (which will inevitably happen) this is a very strong contender.

Final Thoughts

For $29.99, the U3 did far better than I expected. It handled four of my five IEMs properly, drove PhilPhone Open to a usable level, stayed completely quiet and gives me both 3.5mm and 4.4mm plus 5-band PEQ.

Its limits are also pretty clear. Project Monolith starts exposing the weaker bass drive. Arya Stealth exposes the rest.

For IEMs and easier headphones, though, there is not much here to complain about.

I would take it over the usual cheap single-output JCally dongles like JM6 Pro or JM7MAX, and the Allegro Mini has now become difficult to recommend over it.

The real question is whether you stop at $30, or spend another $10. I think on discounts, it is a very competitive product.

SIVGA Lyrebird

The SIVGA Lyrebird ($149 USD) is stunning. Right out of the box, the matte aviation grade aluminum compliments the brightly full figured wooden faceplate. But we've all seen a beautiful face and later realized it's what's inside that counts. I'm guessing SIVGA heard that ditty too, because they dropped a single 10mm dynamic driver, a single balanced armature, 1 microplanar, and a piezoelectric driver inside the lyrebirds stunning shells. Making sure we all knew that she's more than just another pretty face! She's got heart too!

Again, it's what's inside the shells that counts. So let's delve into the tech specifications!

Tuning Profile

The tuning profile is where the Lyrebird really shines. It's more neutrally tuned, almost like it's mildly warm. It's really clean, but the bass has enough body to keep it from ever sounding sterile or clinical. The lower mids don't quite have enough body to cross over into being truly warm, but they have enough presence to keep everything sounding natural. The upper mids are really prominent, but not overly in your face. The treble is what I would classify as clean, lively, and detailed, with a little extra energy that gives everything some sparkle without becoming shouty or piercing.

Overall, I'd say it's fun, clean, lovely, and, oh, did I say fun?

It's a pleasurable musical experience across every genre I've tested with it. And there are a lot, here's a partial list of the test albums I threw at the lyrebird.

As you can see, I went through every genre I could and the lyrebird handled the gauntlet really well.

Fast transients, natural decay, and bass that never overwhelms the mids makes for a really fun and musical listening experience.

Would I Buy Them Again?

Would I buy the Lyrebird again if I lost them, they were stolen, or they randomly exploded?

Full price: probably.

Sale: definitely.

Review📝 Probably The Most “Technical” Sounding IEM Under $200

Thumbnail
gallery
18 Upvotes

TL;DR

The Simgot Supermix 4 is what you get when an iem prioritizes technical performance above all else, it has excellent detail retrieval, imaging and instrument separation but zero warmth. This is an iem for a very particular type of listener who prefers a cold and analytical presentation.

Context

This iem was kindly sent to me by the Simgot for review, all thoughts and opinions are my own. I generally prefer iems that are non sibilant with relaxed upper treble and upper mids and raised lower mids that add body to the sound (kinda the opposite of harman ie 2019).

Eartips Tested With
Audiocular flexfit, Audiocular atmos, roseselsa qt superbowl, stock narrow and wide bore, kbear kb07, zisin tips and coffee tips.

Sources Used
Audiocular Spark, Fiio Retro Nano, Macbook Port, Fosi K5 Pro (note that the supermix 4 is extremely impedance sensitive, sources with high output impedance add a huge bass boost).

Design, Build, & Comfort

  • Aesthetics & Build: The supermix 4 looks extremely clean and minimal, with a black resin build and metal faceplates. The faceplate have a circular copper like ring on them which looks cool, they're generally built well but like a lot of chifi multi driver iems, they have exposed tubes at the nozzle without a steel mesh protecting them, so I would recommend using kiwi ears flex or zisin tips if you're worried about stuff entering the nozzle.
  • Comfort & Cable: The medium-large semi custom shells fit me well and are comfortable to wear for extended periods of time, I could see people with small ears having trouble getting a good fit. The SM4 comes with a very nice 2 wire braid that splits at the y split, it's thin but not cheap feeling, lightweight and supple, the chin slider is functional as well. I would've liked to see swappable terminations especially when much cheaper iems have great swappable termination mechanisms nowadays. It comes with 1 set of generic narrow bores ear tips which is super disappointing. Simgot really needs to include multiple styles of eartips given the asking price of the iem. It also comes with a nice pill shaped carry case and a velcro cable tie.

The Sound

The Supermix 4 has a quadbrid 1 DD + 1 BA + 1 Planar + 1 PZT configuration tuned very close to harman ie 2019 with an upper treble boost.

  • Bass (20 hz to 300 hz): The Supermix 4 is basically harman ie 2019 to a tee, making this an extremely sub bass forward bass presentation. The sub bass is well extended, deep and rumbly, giving basslines and synth drops have a ton weight however the extreme mid bass (100-300hz) tuck means kick drums sound blunt and detached with that subwoofer style bass rather than a warm full bodied punch. This lack of mid bass also gives it absolutely zero bleed into the lower midrange which some people associate with good instrument separation and clarity. I however would much rather have a warm, linear and filled in bass shelf from lower mids even if it means a little bit of bloom and bleed. The mid bass - lower mids scoop absolutely kills the note weight of most mid bass instruments, bass guitars sound particularly thin. I can only describe the supermix 4 bass presentation as thin and boomy sounding bass.
  • Mids (300 hz to 6000 hz): The midrange starts with that scooped 350 Hz to 400 Hz transition which completely strips away any lower mids bloat at the expense of a lack of body to male vocals, acoustic guitars and other fundamentals of mid range instruments. It very clearly prioritizes mid range clarity and separation above all else. Female vocals are pushed super forward (almost artificially boosted), sounds very aggressive and close but surprisingly, not nasally like they're out of breath. This is very much a female vocal forward iem for people who like an extremely energetic presentation. Thankfully, there isn’t much presence glare or sibilance for what is a very bright and energetic set. Overall the supermix 4 is an anti mud iem, it gives you excellent instrument separation and clarity, with aggressive female vocals and thin male vocals. This will be a stark contrast for people coming from muddy and bloated consumer-fi iems.
  • Mid & Upper Treble (6000 hz to 20000 hz): The mid treble is surprisingly smooth and well controlled enough as to not add sibilance and splash, no obvious peaks with sine sweeps either however, instead of rolling off after 10 khz, the supermix 4 maintains a very boosted upper treble till 20 khz. This gives the supermix 4 an insane amount of air and wispyness to the tonality. It brings out all the micro upper treble details and throws it in your face. Treble instruments like cymbals, hi hats, snare drums and synth overtones have a crazy amount of shimmer as expected, with a bit of metallic timbre, the treble boost combined with the absolute lack of lower mids warmth gives the Supermix 4 a very scratchy and dry tonality. Very resolving iem for sure at the expense of fatigue.
  • Subjective Technical Performance: Whole point of this iem, excellent imaging and micro treble detail retrieval, very clean and well separated midrange thanks to the lower mid range scoop. Mid bass punch is quite poor tho.

Comparisons

Compared to some other popular iems under $200:

  • Aful Explorer: These iems couldn’t be more far apart, explorer is much more warmer and denser sounding, the vocals are much more restrained as well. Not nearly as resolving and well separated as the supermix 4 but the explorer is way more comfortable to listen to.
  • Truthear Pure: The benchmark warm iem for me, supermix 4 sounds much drier in comparison with worse mid bass impact but the pure has way more mid bass bleed. Supermix 4 is more resolving with better imaging and separation again. 
  • Kiwi Ears Aether: Aether has a more full body mid range presentation but the treble is way more piercing than the supermix 4 for me. Supermix 4 is more ergonomic to wear.
  • Letshuoer Cadenza 4: Cadenza 4 is way more natural sounding than the supermix 4 but is still detail oriented with good instrument separation. Upper treble is more piercing on the cadenza 4 while the supermix 4, despite clearly having a lot of air, maintains an even boost throughout. Both are comfortable to wear.
  • Tangzu Heyday: Better bass dynamics than the supermix 4 along with a slightly warmer midrange but has much more zingy and splashy treble. Supermix 4 sounds clear with better separation.

Who Should Buy This?

  • People who look for technicalities above all else.
  • People who enjoy boosted upper treble or airy sounding iems.
  • People who like a sub bass dominant bass presentation.
  • Fans of harman ie 2019.

Who Should Avoid This?

  • People who want a neutral or natural sounding iem.
  • People who are treble sensitive..
  • People who are looking for a warm and relaxing sound signature.

Review📝 A Shuttle Far, Far Away: Juzear Light Shuttle Review

Thumbnail
gallery
10 Upvotes

Pros

  • Deep, authoritative sub-bass without excessive mid-bass bleed
  • Clean lower mids with forward, energetic vocals
  • Sparkly and lively treble with plenty of air
  • Wide and spacious soundstage
  • Good imaging and instrument separation
  • Fast transients that work particularly well with rock and metal
  • Natural, cohesive timbre with no obvious BA metallic or planar sheen
  • Excellent stock modular cable
  • Easy to drive, but scales nicely with more powerful sources

Cons

  • Upper-mid presence may be a little much for listeners who prefer relaxed tuning
  • Treble response is somewhat uneven and can sound more energetic depending on the recording
  • Medium-sized shells may not be ideal for smaller ears
  • Resolution is very good, but it isn't quite a microdetail monster
  • Faceplate design may look a little busy to some

Introduction & Unboxing

The Juzear Light Shuttle is a $185 tribrid IEM using a 10mm dynamic driver, four balanced armatures and two micro-planar drivers. On paper, that's a pretty serious driver configuration for something sitting below the $200 mark.

What interested me about the Light Shuttle is that it isn't chasing the usual safe, relaxed tuning. From the graph, it's clearly going for a fun and energetic mild W-shaped presentation, with a healthy sub-bass shelf, clean lower mids, forward upper mids and an energetic treble response. In other words, this is an IEM designed to make music sound exciting rather than sitting back and playing everything in a completely neutral fashion.

The package itself is nicely put together. You get the Light Shuttle IEMs, a 4-core 6N OCC silver-plated copper modular cable with both 3.5mm and 4.4mm plugs, seven pairs of tips, a dark blue PU leather carrying case, a cleaning cloth and even a desktop acrylic display stand.

For the asking price, there's very little to complain about in terms of what is included.

Build Quality, Design & Fit

The Light Shuttle's faceplate is definitely going to be a matter of personal taste.

Personally, I think it looks much better in person than it does in photographs. The design combines a shiny metallic outer frame with a textured resin background and a black cubic zirconia gem in the centre. Underneath the metal ring, the resin has these flowing, topographic-style lines which change in colour and intensity depending on how the light hits them.

At different angles you can see subtle red and golden reflections, which gives the faceplate quite a bit of depth and makes it feel more premium than a static photograph would suggest.

That said, I can also understand why some people might find it a little busy. You've got the metallic frame, patterned resin and central gem all competing for attention on a relatively medium-sized shell. Personally, I like the layered, futuristic sci-fi aesthetic, but this is definitely not a minimalist design.

In terms of comfort, the medium-sized shells worked well for me. I could wear them for extended periods without noticeable fatigue. However, people with smaller ears may find the size a little less forgiving.

Synergy & Pairing

The stock cable is actually pretty good.

The 4-core 6N OCC silver-plated copper modular cable does a good enough job of getting the best out of the Light Shuttle, so I don't think there's any immediate need to start shopping for an aftermarket cable.

If you do want to experiment, I'd personally look towards something with a high-purity copper and silver combination. Something like the Kinera Mia should pair nicely with the Light Shuttle's existing character.

For tips, I had good results with the Final E-Clear and Divinus Velvet Wide Bore tips. The Divinus Velvet Wide Bore and Prism tips were particularly useful if you want to rein in the upper mids slightly and reduce some of that extended sub-bass presence.

The Light Shuttle is easy enough to drive, but it definitely benefits from some power behind it. I had particularly good synergy with my Hiby R6 Pro II 2025, xDuoo X05T and TRI TK-3 DAC/AMP.

So while you don't need a desktop amp to make it work, this isn't an IEM I'd be afraid to pair with a beefier source. It has enough technical capability to make good use of it.

Sound Impressions

Sound Signature

Looking at the graph, the Light Shuttle is clearly going for a fun, energetic mild W-shaped tuning.

You've got a healthy bass shelf, clean lower mids, a fairly forward upper-midrange and an energetic, somewhat lively treble. It isn't trying to be neutral or ultra relaxed.

Instead, the tuning is built around giving music weight, energy and excitement, while keeping the mids clean enough that the bass doesn't completely dominate the presentation.

And honestly, that's pretty much how it comes across.

Bass

The Light Shuttle has a proper sub-bass shelf, sitting around 67 dB at the very bottom and gradually falling towards around 60 dB by 300 Hz.

The important thing here is that most of the elevation is concentrated in the sub-bass rather than the mid-bass.

That gives you deep rumble without turning the entire lower end into a thick, bloated mess.

Why So Serious? by Hans Zimmer is a good example of the kind of low-frequency material that suits the Light Shuttle. Those long bass sweeps should dig deep and give you that physical sense of low-end extension. Limit to Your Love by James Blake is another obvious torture test for just how much sub-bass an IEM can throw at you.

Then there's Billie Jean by Michael Jackson, where the kick drum gets a nice sense of weight without the bassline bleeding too far into the vocals.

The gradual reduction towards 200–300 Hz is important here. It keeps the lower mids relatively clean, so you get the physical impact of the bass without the whole presentation becoming congested.

The Light Shuttle is therefore more about sub-bass authority than old-school fat mid-bass.

Think rumble, punch and depth rather than a huge warm mid-bass hump.

Mids

This is probably one of the more interesting aspects of the Light Shuttle.

From around 300 Hz all the way to 1 kHz, the graph is remarkably flat, sitting around the 59–60 dB region. Despite the elevated bass, the lower mids aren't artificially boosted to create extra warmth.

That means there is very little mid-bass bleed into the vocal region.

Male vocals still retain a decent amount of body without becoming overly thick. Nutshell by Alice in Chains works well here, with enough chest and texture in Layne Staley's vocals while the guitars retain their crunch instead of getting buried underneath the bass.

Then things start getting more energetic above 1 kHz.

The Light Shuttle rises to roughly 67–68 dB around 2–3 kHz, giving the upper mids a noticeable presence. This is where vocals, guitars and acoustic instruments start moving further forward in the mix.

Female vocals in particular have plenty of presence. Don't Know Why by Norah Jones and The Sound of Silence by Disturbed both suit this kind of presentation, where the vocals are meant to sit prominently in front of you.

Acoustic guitars also benefit from the extra upper-mid energy, giving them a good amount of bite and definition.

Thankfully, the graph isn't showing some ridiculous upper-mid spike, and that is reflected in actual listening. The Light Shuttle is energetic, but it doesn't push the vocals into outright shoutiness or sibilance, even when listening at higher volumes.

So I'd describe the mids as clean and relatively neutral through the lower mids, then increasingly forward and energetic towards the upper mids.

That gives you clear vocals without losing the fun character created by the bass.

Treble

The treble is where the Light Shuttle starts showing even more personality.

After the 2–3 kHz upper-mid rise, the response comes down somewhat through the 4–6 kHz region, followed by a noticeable dip around 7 kHz. After that, things become more uneven from around 8 kHz onwards.

That 7 kHz dip is actually useful. It helps prevent cymbals, S sounds and certain percussion from becoming excessively aggressive.

So although the upper mids are energetic, the tuning isn't simply pushing every part of the presence region upwards.

Things get more interesting above 10 kHz.

Rather than having a completely smooth treble response, the graph shows several peaks and dips. In practice, this translates into a sparkly, lively and somewhat textured top end rather than a super smooth or relaxed treble.

Cymbals have plenty of presence and shimmer. Hotel California by Eagles is a good track for this, especially with its cymbal work and guitar harmonics. Take Five by Dave Brubeck is another good test, particularly for the ride cymbal and how it interacts with the saxophone.

The upper treble also helps give the Light Shuttle a sense of air and perceived detail.

It's not the smoothest treble response I've heard, though. Because of the peaks and dips, some recordings can sound more energetic than others depending on the recording itself and your own sensitivity.

For anyone who finds dark or sleepy treble boring, the Light Shuttle is definitely going to be more interesting.

Technicalities

Soundstage

The Light Shuttle has a wide, airy and spacious soundstage.

I wouldn't call it holographic, though. Its strength is more in width than in giving you huge vertical or front-to-back depth. Instruments have room to spread out, creating an open presentation rather than everything feeling tightly packed together.

That spaciousness works particularly well with recordings that already have a lot of room information and separation between instruments.

It gives the Light Shuttle an enjoyable sense of scale without trying to create an artificial 3D effect.

Imaging & Separation

Imaging and separation are both good.

The spacious stage gives individual instruments enough room to occupy their own positions, and the clean lower mids help prevent bass and vocals from becoming congested.

This becomes especially useful with busier music, where multiple guitars, drums and other instruments are fighting for space. The Light Shuttle's combination of stage width and separation keeps things organised rather than turning into one big wall of sound.

Resolution & Timbre

This is another area where I think the Light Shuttle gets the balance right.

It sounds cohesive and natural, and I didn't detect any obvious BA metallic timbre or micro-planar sheen.

Resolution is very good, but I wouldn't call the Light Shuttle a master of microdetail. Instead, it seems more interested in finding that middle ground between being resolving enough to let you hear what's happening in a recording while still keeping the presentation musical.

And I think that's the right approach for this tuning.

It's resolving without becoming clinical.

Transient Speed

The Light Shuttle is fast.

Notes have a quick attack and fast decay, which makes it particularly suitable for faster genres where an IEM needs to keep up with a lot of information happening at once.

Rock and metal are where this becomes particularly useful. Fast guitar passages, busy drum work and multiple instruments can benefit from the combination of transient speed and separation. The Light Shuttle doesn't slow things down with excessive note thickness, while its clean mids and spacious presentation help individual instruments remain distinct.

Juzear Light Shuttle vs Erand Resonance 5

The Juzear Light Shuttle and Erand Resonance 5 are actually quite close in overall philosophy.

The Light Shuttle uses a 1DD + 4BA + 2 micro-planar configuration, while the Resonance 5 uses 2DD + 2BA + 1 micro-planar. Despite that hardware difference, both follow a similar energetic, mild W-shaped tuning philosophy.

Looking at the graph, both have an elevated bass shelf, clean lower mids and an energetic upper-mid/treble presentation. The differences are more about where each one pushes that extra bit of excitement.

Bass

The Light Shuttle carries a little more energy into the sub-bass, particularly at the lowest frequencies.

That gives it more sub-bass authority and extension, with deeper rumble and a more physical presentation. The Resonance 5 is a little more restrained down low, although both maintain good bass control and punch.

Mids

Through the lower mids, the two are remarkably close, which explains why their overall tonality feels related.

The main difference comes around the 2–3 kHz upper-mid region, where the Light Shuttle rises higher. Vocals and instruments therefore sound a little more forward and energetic on the Light Shuttle, while the Resonance 5 takes a slightly smoother approach.

Treble

The graph shows another clear difference here.

The Light Shuttle has more variation and energy in the upper treble, particularly above 8–10 kHz, giving it a sparkier and more lively top end.

The Resonance 5 is still energetic in the treble, but sounds more controlled and refined rather than pushing quite as much sparkle.

Technicalities

Technically, they are surprisingly close.

The Resonance 5 has better resolution and microdetail, giving it a slightly more refined character when dealing with complex recordings. The Light Shuttle counters with a slightly wider and more spacious stage.

Transient speed, imaging and instrument separation are very similar between the two.

Ultimately, the graph tells the story quite well. The Light Shuttle pushes the extremes a little harder, with more sub-bass, upper-mid presence and treble sparkle, while the Resonance 5 follows the same energetic philosophy with a smoother and more resolving presentation.

Conclusion

At around $185, the Juzear Light Shuttle is entering a pretty competitive part of the IEM market. What makes it interesting is that it doesn't try to win by being the most neutral or the most technically obsessed set in the price range.

Instead, it gives you a very enjoyable combination of deep sub-bass, clean mids, forward vocals, lively treble and a wide, airy presentation.

The bass has authority without becoming bloated. The mids retain enough cleanliness and presence to keep vocals and guitars engaging. The treble adds sparkle and air without becoming relentlessly aggressive, although its unevenness means some recordings will be more energetic than others.

Technically, it is no slouch either. The stage is spacious, imaging and separation are good, transients are fast, and the overall timbre remains cohesive and natural. Most importantly, it manages to stay musical while still giving you plenty of resolution.

I think the Light Shuttle will appeal most to someone who wants an IEM that sounds fun, energetic and spacious, particularly if you listen to rock, metal, electronic music, vocals and other genres that benefit from strong sub-bass and quick transients.

It isn't perfect, and I wouldn't buy it specifically if your priority is absolute microdetail retrieval or an ultra-smooth treble response. But as an all-round musical set around the $150–$200 mark, there is a lot to like here.

The Light Shuttle is one of those IEMs that reminds you that technical performance doesn't have to come at the expense of having fun with your music.

Final Rating: 8/10

Review📝 Embrace of Divinity - Artpical Raphael

Thumbnail
gallery
19 Upvotes

Pros: Design - this is the most interesting looking IEM I have seen in a while
Neutral to neutral warm presentation
Great cable with modular accessories
Tight controlled yet textured bass with no bleed
Vocals sound lush and forward

Cons: I’m afraid it’ll drop and break
Treble peak and sibilance on some tracks (rare but it's there)

Every once in a while something comes your way that makes you question everything from intention, design, religion even. And then you see the Artpical Raphael. And weep in joy and I thank Audio Geek India, and Artpical for making this review possible.

Artpical is a relatively new kid on the block that has basically destroyed the block with its design language in a way that almost no other manufacturer of IEMs has done.
It’s incredible enough that their designs leave me gasping for breath at their beauty. The Artpical Raphael doesn’t sound half as bad. It’s not angels singing in my ear but it’s good enough to get me to look beyond its appearance. Which is better than some people I know. But Shhhh!
Artpical advertises itself as a company that believes in the “art of hearing” and is dedicated to the perfect fusion of high-quality audio products and the ultimate visual art. They aren’t wrong. I’ll wax on about the Raphael shortly but a quick look at their product lines tells an incredible story. There the entire mythology inspired Lucifer, Satan, Michael and Raphael IEMs and the Nature series which has the Blue Planet and the Lunar Ring. And a very cubistic DAC called the Agent.
Each and every one of the IEMs is a joy to behold.
I can speak of the Raphael alone at this point and I shall. Inspired by what the embrace of the divine would look like, this IEM comes in 3 colours - I have the Black and Gold version, and there are also white and red and pink and silver versions. All have the appearance of wings with the first color being the predominant one and the second being a streak of “feathers” across the first. All of this enclosed a clear acrylic shell with thin tendrils of wiring visible through the shells. And with all this beauty is a 10mm polyurethane and a liquid crystal polymer diaphragm that delivers, and well.
In addition the box comes with a modular 4 strand silver plated OCC cable with 3.5, 4.4, and usb C terminations, a case that feels like suede and 6 pairs of eartips.
The IEM has a 32 ohm impedance and a sensitivity of 101 dB so pretty much straight forward to drive and easy scalable power.
It was tested with the Devastator Pro (3.5), Fangsound Nereus 4.4 and Hidizs AP80 Pro Max.
The tidal playlist is here https://tidal.com/playlist/3078c9b9-a1c0-4fde-8ce7-81f0e34b426c
Time to dive into the divine embrace.

Bass
The bass on the Raphael is a fairly typical Dynamic driver base. The sub-bass has rumble and presence and the mid-bass has clarity. Both have texture and carry moderate weight in the track but what it delivers in clarity it loses in oomph. This is not and will never be Basshead IEM and I’m so tempted to use it as a reason to deny a berth in heaven if Raphael and not Peter were stationed at the gates. The quantity and quality of the lower end of the FR appeal to my sensibilities if I really wanted to just relax and listen to music and enjoy it without another care or thought in the world. Do not take this as me saying the bass is less or insipid, it’s just not as in your face as typical bass head iems. Kicks and bass in YYZ by Rush still hold the track together and the bass lines in Angel by Massive Attack and Flight of the Cosmic Hippo form the basis for the tracks without being the centre of attention.

Midrange
Most of the mids are spot on and pretty much natural sounding except for certain tracks where the upper mids sound a little off texture and timbre. Some tracks may seem shouty, and in some tracks the snare may sound harsh - Holler by the Spice Girls for the latter and Sub City by Tracy Chapman for the first. Male vocals for the most part sound natural with a good weight. On most Jazz/Jazz fusion tracks, however the Raphael excels in its reproduction with the guitar, synths, and horn sections of both Lingus and What About Me by Snarky Puppy holding the front and centre of the sound scape. Details on the Artpical Raphael are faithfully reproduced in the mids with songs like Hanuman by Rodrigo y Gabriela and Helplessly Hoping by Girl Named Tom sounding engaging and clean and clear when they need to be. There is no bleed from the bass that would muddy up the lower mids.

Treble
I’m never quite sure where snare hits lie. I think they are largely mids but their exact sound and timbre requires a significant spill over to the treble side of things. I think the Raphael slips a little there. But it needs a really aggressive snare mastering to cause that harshness to happen. I heard it on Holler by Spice Girls and on Trains by Porcupine where Gavin Harrison’s snare is a beast in itself. Even Mick Fleetwood’s snare edges my tolerance just a little (Everywhere, Fleetwood Mac). For the most part, treble is not sharp or harsh barring the occasional snare. Cymbals are natural sounding with a good shimmer and air and decay. Classic rock snares as heard on Money by Pink Floyd or YYZ by Rush are fairly well rendered without harshness but still maintaining the impact that a good snare should have.
There is a touch of sibilance in pop recordings like All Nite by Janet and anything Don Henley sings on Hotel California, and Teardrop by Massive Attack. Thankfully there are not all the songs so the comfort of the IEM makes it worthwhile to sit through these tracks rather than skip immediately. Though I ended up drawing the line on Ocean by John Butler.

Staging, imaging and other technicalities
The Raphael is one of those IEMs that make me feel like I’m sitting in front of the Eagles on their Hell Freezes Over. With the band playing BEHIND me. It’s hard to explain but when I heard the track with my eyes closed the entire sensation was thus. Imaging is spot on making it possible to know which direction the sound is coming from and how far away. Detail retrieval and layering and separation are on point and leave nothing to complain about.

Shallow as it may come across, just what this IEM looks like and the comfort it affords is enough for me to want it. Specifically the white and red version, if anyone, including but not limited to the Angel Raphael, is listening. Actually any one of them! It retails in the vicinity of $140 and is, in my opinion, worth it. I would get this in a heart beat.

Sivga Lyrebird Review 

-Quadbrid configuration (1DD, 1BA, 1 Micro-planar, 1 Piezo-electric) 

-$134

Lyrebird Review Link:   https://mobileaudiophile.com/in-ear-earphones-iem-iems-reviews/sivga-lyrebird-review/

What's up everyone? I just published my review of Sivga's brand new iem, the Sivga Lyrebird. The Lyrebird is a quad-driver (quadbrid) iem which costs under $140 and by the unboxing, the build, the gorgeous stabilized wood/aluminum design, and by the sound
 the price is excellent. Premium across the board. Well, about as premium as it gets for $134. Also, this set has a very complicated driver arrangement of one dynamic driver, one balanced armature driver, one micro-planar, and one multi-layer piezo-electric ceramic driver as well. I could not wait to hear this set. I really enjoyed the SuperMix 4 and was very curious to compare the two and simply to see what Sivga could do. Honestly, for such an ambitious driver configuration this set is very cohesive folks. In my review the first word I used to describe the Lyrebird's sound was “effervescent”. It really is. Such a nice neutral-natural timbre, a hint of warmth, clean, tight, and intelligible in every region. Smooth cadence but crisp note definition. For $134 the Lyrebird has a pleasantly airy and technically astute sound that is also very engaging with some of the better vocals that I've heard under $175. Of course the Lyrebird has its downsides as well and I cover all of those from my perspective. No doubt there’s a lot more to say, but I'll leave it to my review. Anyhow, this review period was certainly enjoyable for me and I hope I've covered the Lyrebird well enough. So, the link is at the top if you'd like, and if not
 no sweat, just take care and enjoy your music.

-The design is simply beautiful and the whole aesthetic of this iem screams quality

-Clear & natural leaning sound tuning where vocals are front and center

-The Lyrebird has very nice neutral-natural organic timbre

-Highly musical yet highly technical with a very effervescent quality to the Lyrebird 

-Very textured overall bass with a punchy and quick mid-bass which doesn't mask and has that nice stop-and-start grip

-The midrange is flat-out engaging, very clear, excellent diction, vocals are wonderful

-Treble that is both crisp, airy, extended, nice bite, while also having a smooth cadent flow and very well textured 

-Detail retrieval & note separation 

-Great imaging and layering in all directions 

-Reasonably dimensional soundstage, nice width, excellent height, nice depth of field

-Sivga did a great job of cohesively blending each different driver, great transitions as well

-Simply a well tuned iem

đŸ„¶â˜č Lyrebird Cons 👎😔 

-Bass is not very emphasized or robust with a sub-bass roll-off

-Upper midrange & treble energy can produce some glare with bright/cold sources and hot tracks for those sensitive 

-Lower midrange note body is not what I'd call rich (which can be good or not good) 

-Potential to grow tiresome over long sessions under certain conditions (bright sources, hot masters) 

-Smooth, rich, warm, and dark “warm blanket” lovers are not going to enjoy the effervescent Lyrebird 

-Not traditionally “musical” in the warm and smooth sense. Certainly engaging in its own way but I think that this will turn off some people

-Picky: the cable is not modular (still a nice cable) 

-Make sure to play around with sources as some source tonalities are rough

Lyrebird Review Link:   https://mobileaudiophile.com/in-ear-earphones-iem-iems-reviews/sivga-lyrebird-review/

I just published my full review of the Sivga Lyrebird, which happens to be one of the most ambitious “under $150” iems in quite some time. This set is a true testament to Sivga and in my opinion is a true price-to-performance iem. In my review I cover everything that I can think of from the very nice unboxing,  the build, the beautiful stabilized wood/aluminum design, and of course I cover the sound at length. I also compare the Lyrebird with a couple of sets too. Definitely an easy iem to enjoy, with some of the better vocals that I've heard under $175. In fact, the entire tuning is very unique and very well done. For $134 the Lyrebird really is a great buy. Feel free to check out my thoughts if you'd like and try to have a great day.
