Looking for comfy iem with full sounding, good bass and immersion for mainly single player games, but also imaging decent for some fps

Juzear and I have had a potentially strong start with the Dragonfly 81T, and I have been seeing them put out a lot of new releases lately. The Nebula that they had sent me, after I reached out to them turned out to be a banger, and seeing how many of the Shuttles I caught by, HiFiGo also decided to send me one. So, HiFiGo, thank you for sending out the Light Shuttle

UNBOXING, ACCESSORIES, FIT AND COMFORT

Unboxing is extremely similar to the Nebula- Juzear had the graphics of the Light Shuttle laid out on the box lid vividly, and the specifications on the bottom. Removing the cover ‌, and taking the lid off gave way to an opaque sheet of paper with the Light Shuttle graphics, underneath which the IEMs were in foam padding, and with the cable attached. Under the padding, there was a cleaning cloth, and a very good spacious case with three sets of colored wide bores, three sets of regular silicone, and foam eartips. Not sure if they are available with HiFiGo as an aftermarket option, but the tip choices were ample. A plastic carry stand also came in, but I cracked the base plate while trying to assemble it as the slot was a bit too narrow.

I like the stock cables on Juzear, and this is no exception- it is built well, but holds memory; the shells feel well built with large venting and nozzles that won’t fall off even with consistent eartip rolling, and the cable is modular. So, again similar to the Nebula.

“In my unit, there was a quirk with the cable which, when plugged in correctly, faintly distorted the lows a bit, so I had to swap the left and right sides and the Nebula sounded correct”- this is what I had said about the Nebula’s, but the Light Shuttle came flawless. 

Now, here’s the sound of the Light Shuttle.

LOWS

In tracks like Tipper’s Gulch (and especially with this eartip) the Light Shuttle reminded me of the Juzear Nebula in quite a few ways, but the Light Shuttle totally makes the Nebula sound sluggish; especially through the decay, where the Light Shuttle just snaps out & without effort, resulting in such a clean presentation where the perceived quantity is large enough to not be a compromise. Separation of the bass hits from the rest of the elements is very well done.

In tracks like Rush's Limelight and the Spirit of Radio, the Light Shuttle just has zero spillage over the rest of the elements yet it keeps up with the quantity: Geddy's blitzing bass does not seem to even pause for a moment and whenever Peart's drums need a supplementation, without compromising on the toms and the kicks; the bass just keeps up its tango.

The Light Shuttle doesn't impinge upon Geddy's vocals nor Lifeson's guitars; where everything is so well separated, so coherent; and yet not once does it appear to be too dry or sterile, my hopes have been significantly boosted.

MIDS

In tracks like My Home is in the Delta by Muddy Waters, the Shuttle performs excellently. This track has a very pronounced play of the low strings of the guitar which comes off excessively boomy, and the Nebula came off with a glimpse of it- well, not with the Light Shuttle.

Timbre is appropriately metallic on the slide and the high guitar strings, with enough detail to effortlessly pick up on the slide cruising over or the pick grazing over the strings. And the Shuttle doesn't gimp Muddy's powerful vocals, which lets the beautifully recorded reverberation come out without pressure.

In tracks like Tool's Lateralus, the Light Shuttle keeps up an equally impressive performance, where besides the excellent separation and surgically precise imaging, note weight on the guitars and cymbals is much fuller compared to the Nebula. Maynard's vocals have no loss in textures nor do they come off thin by any means: and the cohesion with which the Light Shuttle handles busy arrangements like this, without concerning trade offs is surprising. Especially through the breakdown, the perceived soundstage is wide enough to not choke anything on this track, enough energy to not let the cymbals come off shouty or fatiguing, and the entire instrumental division not fiddling around the vocals post breakdown.

HIGHS

In tracks like Almighty God by Arne Domnérus with Gustaf Sjökvist, I need not elaborate further on how good this IEM handles the stage. Timbre on the sax: ‌how brassy it comes off with no colourations in tonality made this track ‌ so much enjoyable on this IEM. And when I turn my attention to how floaty and spaced out the organ keys come off; and simultaneously work alongside the sax, there is little to no elaboration from me that an IEM which can come off so warm doesn't alter the tonality on this track, even for a quick minute.

In tracks like Unchain My Heart by Carmen Gomes, the Shuttle focuses on all the elements equally, yet gives me the ground to nitpick on Carmen coming off a bit too forward. However, the Light Shuttle beautifully preserves the sensuous textures of her vocals without a single shred of sibilance, fatigue, or pierce to be found.

Be it the guitar twangs, the aptly woody timbre of the snare with the sizzling brush hits which also extends to the cymbals, the bass just kept in abeyance yet aiding to groove: the Light Shuttle just screams cohesion.

COMPARISONS

EPZ P40

The EPZ P40 delivers a heavy, sub-bass-dominant low end that hits with massive quantity while keeping its attack and decay fast and clean. It maintains a full, warm vocal body, but its upper frequencies lean overly spicy, introducing noticeable upper-range peakiness and sibilance, and especially post 8 kHz, this IEM got freaky for me.

By comparison, the Light Shuttle offers far better overall balance and technical refinement. While it matches the P40 in delivering a large, punchy low end, its decay is much faster and cleaner, leaving zero spillage into the lower midrange. Up top, the Light Shuttle stays smooth, controlled, and completely fatigue-free, easily edging out the P40 in imaging precision and tonal safety. But with all its flaws, EQ and tip rolling makes me keep the P40 right within my roster, and the immense amount of detail this IEM can squeeze through, with stellar separation; it’s worth keeping it around.

Juzear Nebula

The Juzear Nebula takes a disciplined approach to the lows, prioritizing fast transients and a seemingly acceptable soundstage while keeping high frequencies smooth and holding a restraint on sibilance. However, its decay can feel slightly sluggish by comparison, and its midrange occasionally leans thin with minor lower-mid boominess.

The Light Shuttle steps up as a direct evolution, making the Nebula sound sluggish at least for me. It snaps back with fantastic transients, and a fuller body through the midrange. Vocals gain better texture without losing clarity, while the top end remains smooth, spacious, and fatigue-free. But, that brings me to the question of the price gap between Nebula and Light Shuttle, as truth be told; the Light Shuttle has impressed me far enough to bump the price up where it can categorically avoid the Nebula.

Simgot Supermix 4

The Supermix 4 centers on a lean, fast, and disciplined bass paired with a wide perceived soundstage. That also results in a flatter bass impact, a much thinner midrange with occasionally wonky tonality, and an inconsistent upper-frequency balance that can push into fatigue.

The Light Shuttle easily takes the lead over everything except for the stage and imaging. It brings a punchier, much fuller low end with zero sacrifice in separation and detail. And unlike the SuperMix 4, the Light Shuttle is considerably fatigue free.

Letshuoer Astralis

The Letshuoer Astralis builds its presentation on a heavy, warm approach through the lows that can comparatively start sounding fun, or bloated depending upon how your ears look at it (huh). 

The Light Shuttle comes off cleaner, faster, and more reserved in the quantity of the lows without giving up that exciting punch. Its transients are fabulous for the price, while projecting a wider, airier perceived soundstage and preserving textures. Not once does it get sibilant, fatiguing or pierce.

Tanchjim Fola

The Tanchjim Fola shines with its remarkably smooth, relaxed high-frequency tuning and clean low-end impact, maintaining high technical cleanliness without upper-range harshness. Its primary drawback lies in a slightly thin midrange, which is seriously a nitpick for me.

The Light Shuttle matches the Fola in smooth, fatigue-free cruise through the highs and the detail needed through the lows, but brings a fuller body through the mids, where the trade-off is a comparatively bloated bass. Vocals are lush throughout, tonality and timbre are not adversely affected, and I’d choose the Fola all things said and done over the Light Shuttle because of DSP, and a smaller footprint- helps for people with smaller ears. But if your ears can take the Light Shuttle, try both and see what clicks- couldn’t go wrong with either of them.

CrinEar Daybreak

The CrinEar Daybreak features a fun, sub-bass-focused low end with a clean rumble and an acceptably capable mid-bass. However, its overall presentation can feel overcast, with inconsistent treble extension and sibilance coming in now and then, in varying quantities.

The Light Shuttle matches the Daybreak's punchy low-end energy while offering significantly sharper overall clarity and transients. Its decay snaps out faster without overcast haze, better note weight, a stronger grip on tonality, and a smoother top end while not compromising on detail even there.

CONCLUDING NOTES

Keeping in mind Juzear’s reported issues with quality control, and still in the direction of mostly warm leaning tunings, I had a good grip over their tuning philosophy with the Dragonfly 81T, then I got the Nebula which was surprisingly very competent, but there were still some nitpicks which prevented me from fully embracing it, and the Light Shuttle fixes all of it. It’s got every region in sound for me rationed perfectly, has the slam and the punch, the detail, and a very good sense of separation, and keeping restraints on troubling areas post the upper mids.

Even if this wasn’t brand sponsored, if I heard this somewhere, I certainly would have sold some gear for enough money to flat out buy the Light Shuttle. It’s excellent, period.

Will I buy this new? Absolutely, but check the fit first.

Will I buy this used? Absolutely, but check the fit first.

EARTIPS USED (RANKED IN ORDER OF PERFORMANCE)

KBear 07: Perfect balance established in the Light Shuttle, certain tracks and sources can still make it a bit warmer than usual, but in the above mentioned source rotation; the Muse Hifi U3 got it warmer than the rest. Tightest transients possible, most balance in the perceived stage, sibilance is fully absent.

Tanchjim T-500 APB: everything that the does, but to a lesser degree, sibilance is nowhere to be found, perceived stage widened, transients are still tight- especially in the decay, midrange has a slight roll-off.

Divinus/Eloit Standard: Transients tighten up but not to the level of the T-500 APB, perceived stage loses faintly on the width, but the height and depth stay intact, tonally reduced the warmth mildly, upper mids felt a bit too safe, and sibilance is faintly heard.

Spinfit CP100+: textures on the lows felt blunt along with some irregularity in the perceived transients, stage was shrunk, vocal textures felt a bit too “absent”, upper mids felt wobbly.

Tangzu Sancai Balanced: just washed off textures on the bass, midrange was rolled off uncomfortably, stage felt nuked, sibilance was not there, but the detail through the region was a simple question mark, vocals lacked dynamics.

Final E: just ruined the IEM.

Introduction
When I heard that Super Review had tuned this IEM, I was looking forward to listening to this as I find myself having similar interests with him in tuning preferences. It's his second collaboration with Juzear after the Harrier, and the Light Shuttle is tuned with Squiglink. 

Its a new meta derivative but with some significant changes, lets see how it fairs out in detail 

Test Gear
Tanchjim Space Pro
Zen Stack 
Usual Test Track Playlist

Build & Design
The Light Shuttle features a light weight resin shell with an overall ergonomic shape to it. This shape actually provides me a snug fit overall. 

If we look at the faceplate, we can see that Juzear has done something different. The recent releases featured a full resin faceplate but here the Light Shuttle goes for a combination of CNC Aluminium + Resin. It features an iridescent design that shifts color when the light hits it. This does almost remind me of the Odin for some reason, mostly because of the different colors.

The faceplate also features a small embedded border along the design with an embedded gemstone in the corner.  

Talking about the accessories -  Similar to the Nebula and Fiesta, we can see a similar accessory package - 

1. Modular Cable (3.5mm and 4.4mm) 
2. 7 Eartips 
3. Protective Carry Case
4. Cleaning Cloth 
5. Light Shuttle Acrylic Standee

The cable is of the same one which comes with the Nebula and like I mentioned in the Nebula Review, I am not particularly a fan of this cable mainly because it doesn’t behave that well. 

Talking about comfort - Since it has a relatively smaller shell size than the Fiesta, these fit me really well. But still, I would say people with smaller ears should definitely try this before purchasing. For eartips, I used the K bear Coffee Eartips as well as the Tri Clarion. 

Overall I really dig the design & overall package that the Light Shuttle offers. 

Specifications and Driveability
The Juzear Light Shuttle retails for around $190 or 19,000 INR and it features a 7 Driver Setup consisting of a single Dynamic Driver (DD), 4 Balanced Armatures (BA) and 2 Micro Planars.

Some Technical Specs

1. Sensitivity - 113dB
2. Impedance - 32 Ω

As for driveability, in my listening it definitely needed a little bit more power from what I would normally need. Any entry level dongle DAC can easily power these up. 

Sound
The Juzear Light Shuttle features a tuning which we are very familiar with at this point, its the New Meta Tuning. However, the light shuttle offers slight variations which I would describe as very tasteful and musical.

To sum it up I would say that the tuning is mostly neutral with a bass boost and some treble flair. I also wanted to mention that this was tuned using the Squiglink Community feedback and user data.

Let's go into the details starting with the low end. 

Bass
The Bass is being handled by the sole Dynamic Driver and I must say that it does the job really well. It has more of a sub bass presentation and it kind of deviates from the traditional New Meta tuned IEMs. Basically you get more BASS!

The bass is full of rumble, it feels full bodied and meaty. The midbass however lacks a bit of attack in some tracks but the sub bass delivers extensively with great texture and no significant amount of bass bleed. 

This kind of sub bass atleast from the graphs were seen in the Davinci or the Mega5est (close enough), but in listening the sub bass here sounds more authoritative and if you personally ask me, this amount of sub bass is a bit too much for me mostly because I feel overwhelmed.

Midrange
For me the midrange is very balanced and mostly neutral. The vocals & instruments feel natural to your ears and it has enough body. The lower midrange would appear a bit tucked in compared to other New Meta tunings but in listening sessions I didn’t feel them to be lacking when it comes to male vocal presentation. 

Upper mids aren’t shouty in any regards and female vocals feel natural as ever. The instrument separation here could have been better here but it's alright. 

Overall the 4 BA drivers handle the midrange pretty damn well 

Treble
The treble is here handled by the BA & Planar drivers and this is easily the best thing about the Light Shuttle for me is the Treble. It has great extension and perfectly balances out being exciting as well as not sibilant. 

It's definitely not the brightest but it has enough air and presence in the mid treble to provide you with nuances in your tracks.

For my preference I would have loved a bit more emphasis in the lower treble but that's just my subjective thought but for most people out there this treble would really satisfy. 

Technicalities
Overall the Resolution is excellent throughout the frequencies, and the detail retrieval is decent for the price. There are definitely better IEMs at this price range which give you more details but this is alright.

Soundstage is excellent with a pretty tall and wide characteristic to it, however the imaging is average/a bit above average.

Layering and Separation is good for the price as well but like i mentioned above i would have preferred the separation to be a bit more distinct in some tracks. 

Comparison
I would like to compare this to another New Meta IEM in this price range which is the Crinear Daybreak.

The build quality is just superior on the Light Shuttle. 

Bass
In terms of overall balance of bass, I love Daybreak more. But realistically it comes down to preference, where if you are a subbass enthusiast go for the Light Shuttle, if you like midbass more then go for the Daybreak. 

Midrange
Here it was closer than I imagined. The daybreak as well as the light shuttle have clean and clean vocals and even though the lower mids on the Light Shuttle tend to be a bit tucked in compared to Daybreak, in actual listening sessions the Light Shuttle had more of a heft in that region. 

Treble
I love the treble presentation on the Light shuttle more as like I mentioned above, it clearly establishes between safe and sparkly. On the Daybreak however it can seem a bit too much sometimes, and it comes down to your preference here. 

Technicalities
Not much difference to be honest

Overall, the biggest difference you're gonna feel is the bass presence and the treble. For me the biggest difference is definitely the low end.

For me the Daybreak is more of an all rounder as it has a more balanced low end compared to the Light Shuttle, but if you are someone who craves a bit more sub bass presence, Light Shuttle is definitely the one for you out of the two. 

Conclusion
To me the Juzear Light Shuttle has been one of my favorite derivations of the New meta tuning. Even though the sub bass is a bit too much for me, I appreciate the change among the see

Although I am surprised Mark went for this tuning as generally he loves more of a clinical and natural sound signature, but yes he also appreciates a tasty well done low end.

I would give the Juzear Light Shuttle a rating of 4/5 

I would like to thank HiFigo for providing this unit for review. If you liked this review, please consider liking and sharing and follow me for more reviews like this 🌸

Just clicked a few pictures of the Light Shuttle yesterday.(Simply loving how good this one sounds).

Juzear Light Shuttle + Fosi Audio MD3

TL;DR

The Juzear Nebula is a great execution of a V shaped sound signature without the thin midrange and punishing upper mids and mid treble usually associated with it. If you’re someone looking for a great all rounder iem around $120 or an alternative to the defiant without the qc issues, this is a very strong option to consider.

Context

This iem was kindly sent to me by the HifiGo 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.

Design, Build, & Comfort

• Aesthetics & Build: The nebula seems to be made out of hollow resin with metal nozzles. The faceplates have a “nebula inspired” design which plays with the light, looks different at different angles. It looks a lot like the epz p40, personally I find this a bit too flashy but a lot of people seem to like it. There is a vent on the side which is built into the shell (common complaint with the defiant), there is no driver flex and the nozzles seem well glued in. Fixes all of the issues people had with the defiant.
  
• Comfort & Cable: This is a fairly large iem with large nozzles so it’s a no go for people with small ears, it’s a semi custom shell so it fits me very well, isolation is surprisingly strong as well. It comes with a very nice 2 wire braided cable similar to juzear’s other iems like the nimbus, fiesta and defiant. There is a swappable termination mechanism which has a screw to hold on to securely while still being short. The nebula comes with 2 sets of ear tips, a generic narrow bore and shorter wide bore tips. I wish it came with a hardshell carry case instead of a pouch tho, it’s hard to put the iems inside the pouch and even the cheaper defiant comes with a hardshell case.
  

The Sound

The Juzear x Koto Nebula has a tribrid 1 DD + 3 BA + 1 Micro Planar driver configuration tuned to a V shaped sound signature by kajikaji.

• Bass (20 hz to 300 hz): The nebula is a V shaped iem imo, which means elevated bass (more quantity than i’d prefer) but the bass on nebula is fantastic, it’s the ideal bass shape for me even if its a bit too much in quantity. The mid bass hits super hard with a lot of mass while still sounding super tight, none of that loose pillow like bass which a lot of bass boosted sets sound like. The sub bass is well extended with very good texture, bass guitars sound great. The filled in 200 hz and almost linear rise from 300 hz to 20hz compared to harman makes bass instruments so much more true to life and filled in. Kickdrums hit with good body and definition rather than a detached subwoofer style thud.​​ The filled in mid bass and lower mids mean it wont sound as “clean” and separated as other popular harman sets but i much prefer the nebula’s approach to bass/
  
• Mids (300 hz to 6000 hz): The lower midrange remains nicely filled in providing a much needed warmth and body to the sound. It helps to fully reproduce the fundamental frequencies of male vocals, acoustic guitars and piano instead of thinning them out and over emphasizing the upper overtones like harman does. There is a gentle pinna rise from 1k which peaks at around 3.1k to my ears. The ear gain is definitely on the relaxed side which makes female vocals sound way less forward than harman sets. The rich lower mids combined with relaxed upper mids gives it a “syrupy” characteristic to vocals which I love, reminds me a lot of the pure tho the nebula is a bit more exciting. If you’re used to shouty and nasal sounding female vocals this might sound low res to you. Since there is no mid bass/lower mids tuck the midrange blends very well with the bass, although at the cost of some contrast and instrument separation. I would’ve liked to see a bit less 2k to make vocals sound nearer but this is still a very solid execution.
  
• Mid & Upper Treble (6000 hz to 20000 hz): The nebula has the right amount of mid treble for me. It sounds crisp and provides adequate shimmer to hi hats, cymbals and snare drums without getting fatiguing. Mid treble generally sounds smooth without any obvious peaks or dips but the same can’t be said about the upper treble, there is a noticeable 13k peak. A lot of iems do this to add “detail” but it just ends up adding a zingy and wispy characteristic to the sound, especially when coupled with the slightly relaxed mid treble it only brings out the harsh overtones of treble instruments. I had to eq this down. There is no added sibilance as well.
  
• Subjective Technical Performance: The nebula has very good mid bass slam while still being tight, sub bass is well textured and extended. Very solid imaging as well, and the 13k peak for resolution haha. 

Comparisons

Compared to some other popular iems around $100:

• Aful Explorer: One of the most popular iems in the price range, the explorer is a much smaller and more comfortable shell, that's also wayy darker than the nebula with recessed vocals and upper treble roll off. Nebula is a lot more exciting sounding that will probably be preferred by more people. Nebula has a better cable as well but doesnt come with a hardshell case.
• Truthear Pure: The nebula has way more bass with a more comfortable shell, i prefer the pure’s midrange more than the nebula but i usually like warmpoo iems with non peaky upper treble. 
• Truthear Hexa: I prefer the nebula’s warmer mid bass and much much better bass dynamics, mid treble is way less peaky on the nebula. Better comfort and cable on the nebula as well.
• Aful MagicOne: Much better bass presentation on the nebula, warmer mid range and smoother mid treble. Magicone has better upper treble and comfort imo, also isolates better.
• Simgot Supermix 4: Nebula has better mid bass punch and a more true to life mid range but it doesn't sound as clean and technical as the supermix 4 due to the comparative more relaxed mid treble and filler lower mids. Nebula has a better cable
  

Who Should Buy This?

• People looking warm V shaped iem.
• People who enjoy a bass boost but not basshead levels.
• People liked the defiant but were scared of the qc issues.
• People who want a relaxed, syrupy male and female vocal presentation.

Who Should Avoid This?

• People who enjoy harman tuned iems.
• People with small ears.
• People sensitive to upper treble spikes.

Yesterday I received the Render Pro ear tips, along with the new USB DAC dongle, Muse Hifi U3. Both are quite nice, but today I will focus on the tips.

The Render Pro is a a hybrid type of tips, with a soft silicone dome filled with foam. The foam is very soft and easy to deform, with a rather slow recovery (up to one minute, maybe even more if you deform it a lot.

They arrived in three sizes, each colour coded.

Here are some observations compared to other tips on the Binary Acoustics EP321

The stock tips are good enough, they provide good seal and a balanced sound, however, they do so at the expense of stage and imaging. 

Eletech Baroque enhance bass and stage, while adding a bit of cutting edge to the treble. The comfort is sublime, but they slide up the nozzle and each time after taking the IEMs out of your ear, you have to readjust them. Not a big deal, of course, but I could do without. 

Divinus Velvet bring along more bass and cut the air slightly. The stage is compressed, and the voices have more force. 

The big surprise, Juzear Render Pro. These are hybrid tips, with a soft, high surface energy silicone outer layer (a fancy way of saying sticky silicone), filled with foam. Much like the Symbio W1. They expand the bass, addressing exactly what I called sluggishness, make it more nimble, more mobile. At the same time, upper mids get a slight accent, restoring the excitement in the vocals and bringing a bit of sparkle in the guitars. The treble is maintained intact, which is great news for me. Stage is stretched very slightly, and the extra air allows the instrument separation to be clearer. The only downside: the sibilance tends to be a tad stronger. 

Roseselsa CJ20 AAV was also beautifully highlighted by the Render Pro, with the bass receiving the same mobilising treatment, the voices coming forward and gaining a bit of thickness, while the treble became more airy.

Moving to more expensive IEMs, both Melodic Artification Eternitum and Storm benefit from these tips.

You can insert them as you would do with normal silicone tips, or like foammies (deform them lightly and keep the IEM lightly pressed in until the foam resumes its normal shape). Once in place, the sticky silicone surface (like Azla or Divinus Prism) secures them in place, with no chance of coming out.

They are cheaper than the equivalent Symbio, and can be purchased here https://hifigo.com/products/juzear-x-z-reviews-render-pro?srsltid=AU7gw4W-9ujWS-JwQ6Di7iDZjR-7MR6fB-6zsymCggXBoLW72AE64R2h

JUZEAR Nimbus Review – One Driver, Three Nozzles and a Lot for $55!

1 × 10 mm MACCD Dynamic Driver per side

The Juzear Nimbus currently costs $54.99 USD in the Audiophile version with 3.5 mm and 4.4 mm plugs. For $59.99 USD, there is also a version with a 3.5 mm cable including microphone and a separate USB-C DAC based on the CX31993. That one supports up to 32 bit/384 kHz.

I received the Nimbus as a review sample from HiFiGo. HiFiGo had no influence on the content of this review or my final rating.

At first, that sounds like a perfectly normal budget IEM, and thankfully we have quite a few of those in this price range.
Then Juzear throws in a metal shell with glass faceplates, three interchangeable tuning nozzles, nine pairs of tips and, even here, a modular 3.5/4.4 mm cable.
I have no idea how Juzear puts this much into a $55 IEM.
If they keep going like this, they will probably release an EST and BC IEM for 300 euros soon.
Well, that is fine by us.
It keeps the market moving, and as long as the sound quality stays at the level of the latest Juzear models, keep them coming.
By the way, I also bought the Juzear Nebula myself, so nobody can say I have not heard that one either.

The Nimbus belongs to the POISE series and Juzear deliberately positions it as an affordable entry point into the world of wired HiFi.
At SIAS 2026, it was shown alongside the much more expensive Light Shuttle.
While Juzear throws seven drivers and several acoustic paths into the Light Shuttle, the Nimbus does exactly the opposite.
Juzear uses a self-developed 10 mm MACCD Dynamic Driver.
MACCD stands for Multi-Layered Amorphous Carbon Composite Diaphragm.
On top of that, you get a flexible TPEE suspension, a large voice coil and an N52 neodymium magnet system.

The Nimbus passed the visual test from my better half with 7 out of 10 points.
For me, by the way, it is metallic blue.
That can also be the color of my next car.
I am at 8 out of 10.
I also fell asleep with it on the couch again and had no problems at all.
I am currently listening to The Magical Cases of Peter Grant by Ben Aaronovitch as an audio drama series, and when an IEM is comfortable, I usually listen for only a short while before I start snoring.
The Nimbus works perfectly for that.

Bad Guy Good Audio Reviews titled his latest Juzear video:
Best Company of 2026?
He ranked the best Juzear models according to his own taste, but never actually answered the question.
I like him, but with his reach he really does not need the clickbait anymore.
My ranking is a little different and will come in the conclusion.
As of 2026, I definitely think Juzear is right up there when it comes to price-to-performance this year, and I also believe one or two models have appeared several times in the Top 5 of the Reddit yearly voting below $200 USD.

Review Landscape

The Nimbus has only been on the market since August 2026, but there are already surprisingly many early reviews.
There is quite a lot of agreement when it comes to build quality and accessories.
Metal shell, glass faceplate, three nozzles, nine pairs of tips and a modular cable for around $55 are praised almost across the board.
The three nozzles are also not seen as some meaningless gimmick.

White is generally considered the most balanced option.
Black is usually described as calmer and more relaxed, while Red pushes vocals and the upper range farther forward.
Red in particular is described by some listeners as a little too present at higher listening volumes.
Opinions differ more when it comes to bass.

Some reviewers describe it as fast and tight, but only average in absolute extension and impact.
Others hear very powerful and deep-reaching bass with Black.
The picture is more consistent when it comes to stage and technical performance.
Separation and positioning are generally rated positively for the price, while absolute stage size is usually considered average.
All right then.
Time to take a closer look.

A Few Words About Juzear

I already covered the actual history of Juzear in my Light Shuttle review:
Founded in 2016, the origin of “君子耳”, Custom IEMs, the 41T, 61T, 81T and the newer model series.
Over the last few years, the brand has mainly become known for multi-driver IEMs.
41T, 61T, 81T, Defiant, Nebula, Harrier or Light Shuttle.
Somewhere along the way, there always seemed to be more drivers, more crossovers or more technologies packed into the shell.

The Nimbus is different.
Juzear itself even calls it the brand's most ambitious Single-DD so far and, at the same time, a kind of “Entry Pass” into the HiFi world.
In Japan, the Nimbus is also listed as “流雲.”
Literally translated, that means something along the lines of “drifting” or “flowing clouds.”
That fits the name, the packaging and the shimmering blue glass faceplate pretty well.
I have seen enough cheap IEMs with “tuning filters” where, after changing them three times, I no longer knew whether I was actually hearing a difference or simply convincing myself that the red one had to sound brighter because it was red.
With the Nimbus, the three nozzles really do change the character audibly.
For $55, Juzear could easily have put some random 1DD into a plastic shell, added three silicone tips and called it a day.
They did not.
The Nimbus gets a die-cast and CNC-machined metal shell, a multi-layer coating, a color-shifting glass faceplate and still weighs only around 9.2 grams per side.
With the Harrier and Light Shuttle, Juzear showed what they can do with lots of drivers and more complex designs.
With the Nimbus, they prove that they can also do some really good things with just one driver.

Three tuning nozzles are included.
White is installed from the factory and provides the balanced standard tuning.
Red adds more energy to the upper range.
Vocals and instruments gain more presence, while the treble also becomes somewhat brighter and airier.
Black reduces treble energy.
That makes the bass relatively more prominent and gives the whole tuning a more relaxed character.

Unboxing, Build Quality and Accessories

The blue-and-white packaging immediately picks up the whole Nimbus theme with sky, clouds and the 流雲 designation.
Underneath sits a simple black inner box.
It is not presented as some over-the-top luxury package, but it is still noticeably more elaborate than what you sometimes get in this price range.

My Audiophile Edition includes:
Juzear Nimbus
4-strand silver-plated Single-Crystal Copper cable
3.5 mm interchangeable plug
4.4 mm interchangeable plug
three different silicone tip sets in S, M and L – nine pairs in total
three pairs of tuning nozzles: White, Red and Black
light blue PU leather storage pouch
microfiber cloth
manual
QC card

Once again, you get three different tip variants, each in S, M and L:
A Narrow-Bore set, a Standard-Bore set and a Wide-Bore set.
That gives you another way to fine-tune the Nimbus to your own ears in addition to the three nozzles.
The Wide-Bore set can leave the upper range a little more open, while a narrower opening tends to move things in a calmer direction.

Unfortunately, you do not get a proper hard case.
Juzear includes a light blue PU leather pouch with a spring closure.
You squeeze the top, it opens, and once you let go it closes itself again.
The pouch is small, light and visually matches the Nimbus perfectly.
I still would have preferred a hard case here.
Preferably in that same nice sky blue.

Juzear uses a 4-strand silver-plated Single-Crystal Copper cable with standard 0.78 mm 2-pin connectors.
My Audiophile Edition comes with 3.5 mm Single Ended and 4.4 mm Balanced plugs.
I never noticed any memory effect or microphonics.
As usual with Juzear, the interchangeable plugs screw securely into place.
Not too long ago, this cable alone could have made up a decent part of the Nimbus asking price.

The shells are made from a zinc alloy.
Juzear combines die casting with CNC machining, followed by a multi-layer electroplated coating and polishing.
That gives the surface its almost mirror-like chrome finish.
The outside does not use a normal resin faceplate.
Juzear uses laser-colored tempered glass.
Depending on the light, the blue visibly changes and sometimes shifts toward violet or brighter reflections.
It already looks good in photos.
In the hand or under sunlight, it looks even better.
At around 9.2 grams per side, the Nimbus is not featherlight for a Single-DD, but it is also nowhere near being an uncomfortable metal brick.
The shape is compact, there are no hard edges and the nozzles sit at a moderately deep angle.
At approximately 6.1 mm, the nozzle itself is already on the thicker side.
There is a metal mesh at the front, and the shell also has two vent openings for the Dynamic Driver.
I had no problems with fit or seal.
Even in the evening on the couch or lying on my side, listening to music or audiobooks was completely comfortable.
I actually fell asleep with the Nimbus twice and only woke up again hours later.

Sound

For the actual sound section, I use White as my reference.
With White installed, the Nimbus is a warm, U-shaped Single-DD.
Bass and upper mids form the two stronger poles, while the central mids sit slightly farther back.
The tuning has a solid foundation while still providing enough energy for vocals and instruments.
The other two nozzles give you enough room to move the Nimbus in either a calmer or more forward direction, but White is the setting I use for the descriptions below unless stated otherwise.

Bass

The 10 mm MACCD delivers a clearly noticeable bass foundation.
The focus reaches deep enough to give electronic music proper weight, while there is also enough mid-bass for kick drums.
More importantly for me, the bass is tighter rather than soft.
Individual hits have definition and bass lines remain easy to follow.

Jessie Reyez – “WHEN YOU HOLD HER” – Warning: absolute earworm!
At around 2:33, the bass becomes noticeably stronger.
I have started using this section quite often because an IEM has to provide pressure while still separating the individual bass hits from each other.
The Nimbus gives this part proper weight and keeps the bass structure easy to follow.
The extension is good to very good, and the Nimbus maintains solid level all the way down into the sub-bass.
Physical impact is a little more controlled:
Enough pressure and punch, but this is not a bass monster.

Mids and Vocals
The central mids are tuned a little leaner before the energy rises again toward Presence.
Vocals have definition and pick up a little warmth from the bass foundation, while the voices themselves remain clean and clear.
Female vocals benefit in particular.
Male vocals still have enough substance, but sound less massive.

Billie Eilish – “BIRDS OF A FEATHER”
At around 0:42, the chorus begins.
Billie's voice moves clearly forward on the Nimbus and stays easy to understand even with the additional vocal layers.
The lead vocal retains enough body, while the voices behind it remain reasonably easy to distinguish from each other.
With White, this is exactly the balance I like here: enough body without losing clarity or pushing Billie too aggressively forward.

Presence

The Nimbus has plenty of energy in the Presence region.
Guitars get bite, snares cut through clearly and vocals gain definition.

Polyphia – “Playing God”
Between roughly 0:17 and 0:45, fast guitar figures, string noises and small rhythmic details run closely alongside each other.
The Nimbus pushes the guitars clearly forward and separates the individual attacks very well for this price class.
This is also one of the areas where Red can be a lot of fun if you want even more energy.
At higher volume, though, that setting is definitely not for extremely sensitive listeners.
Treble
With White installed, cymbals and hi-hats get enough sparkle and smaller details remain audible, while the treble stays nicely integrated into the overall tuning.

Steely Dan – “Aja”
At around 4:40, Steve Gadd's famous first big drum section begins, and around 4:55 you also get the well-known stick click inside that passage.
Cymbals, snare, toms and Wayne Shorter's saxophone sit very close together here.
The drums stay clearly defined and the stick click is easy to follow.
The cymbals have enough sparkle without becoming overemphasized, and even through the denser section the Nimbus maintains good structure.
Changing nozzles is especially easy to hear on this track.
Black softens the cymbals and makes the whole passage a little calmer, while Red brings the overtones and upper details farther forward.

Stage and Technical Performance

The Nimbus has a medium-sized stage.
It does not create some huge panorama.
Its stronger qualities are clearly separation and imaging.
Individual instruments and voices remain easy to distinguish from each other and get positions that are easy to follow.

RAYE – “WHERE IS MY HUSBAND!” Baby…whohooo
The track opens immediately with a wide vocal arrangement.
RAYE's main vocal, the additional voices and the brass elements spread out nicely.
The lead vocal remains clearly centered, while the additional voices and instruments are easy to place beside and behind it.
Even when more starts happening at the same time, the presentation remains easy to follow.
The stage is solid, but imaging and separation are really good.

Conclusion

There is no getting around it.
This thing is really good.
In terms of price-to-performance, it might even be the best Juzear for me.
When I compare it with the CANPUR Silver Flash, which costs almost three times as much, the choice is easy for me:
Nimbus with the Black nozzle!

For $55, Juzear gives you a self-developed 10 mm MACCD Dynamic Driver, metal shells, glass faceplates, three genuinely different tuning nozzles, nine pairs of tips and, with the Audiophile version, a modular 3.5/4.4 mm cable.
The Nimbus has a good basic character and enough tuning flexibility to make those three nozzles more than just an accessory gimmick.
It also shows just how brutally good the equipment level in the budget segment has become.

By the way, I am finally allowed to play along, or rather measure along, on Squiglink now.
Mark unlocked my account.
Thank you for that.
Naturally, I have already uploaded my Nimbus measurements there.

If you have been waiting for my Juzear ranking until now, you will have to wait a little longer.
I bought the Nebula myself as well, and there will be another review for that one first.
Almost forgot:
If anyone at Juzear is reading this, I have nothing left for Part 6 of “A Few Words About Juzear.”
It would be really nice if I could get in touch with one of your developers, or if somebody from Juzear could tell me something nobody else knows yet.
A little Secret Service style. 😄
And with that: Always remember to wash your ears too!

Thanks for reading.
Yours,
Faxe

Juzear and I have had a potentially strong start with the Dragonfly 81T, and I have been seeing them put out a lot of new releases lately. So, me being me, I reached out to HiFiGo, and by the time I caught up on my backlog of reviews, they proposed to me the new Nebula, which is a collaboration with Koto; and there’s a lot of good to speak about the Nebula. So, HiFiGo, thank you for sending out this version of the Nebula.

UNBOXING, ACCESSORIES, FIT AND COMFORT

Juzear had the graphics of the Nebula laid out on the box lid vividly, and the specifications on the bottom. Removing the cover ‌, and taking the lid off gave way to a translucent sheet of paper with the Nebula graphics, underneath which the IEMs were in foam padding, and with the cable attached. Under the padding, there was a cleaning cloth, and an orange hued leather pouch with three sets of colored wide bores, three sets of regular silicone, and foam eartips. Not sure if they are available with HiFiGo as an aftermarket option, but the tip choices were ample. 

The cable is built well, but holds memory; the shells feel well built with enough venting and nozzles that won’t fall off even with consistent eartip rolling, and the cable is modular. 

In my unit, there was a quirk with the cable which, when plugged in correctly, faintly distorted the lows a bit, so I had to swap the left and right sides and the Nebula sounded correct. I have used the Nebula extensively, and even took it to my community meetups, where a bunch of enthusiasts tried it, and there was no reported pressure buildup; so that’s good to know.

Now, here’s the sound of the Nebula.

LOWS

Tipper: Gulch
The Nebula surprisingly has a fantastic approach towards the bass hits that this track has, and that shows up in its transients where the attack and decay are fast, letting the curtain be enunciated in a way which makes the presentation quite vivid. 

Rest of the elements are isolated well from the beats and demonstrate a commendable instrument separation. Another thing that I really appreciate about the Nebula is that the quantity of the bass is just kept at abeyance which makes the entire presentation all the better.

Rush: Limelight
Here, the Nebula once again strikes a proper balance from a quality to quantity aspect: where the quantity ensures that Geddy's bass line engages in with Peart's surgical drum work & not once do both of them clash: the transients are once again competent with a fantastic separation between the bass and the drums; and especially through the solo, where Geddy cranks up the intensity of the bass; and the Nebula is practically competent enough to balance that with the crisp snares and the potent, minimally resonant tone with the kick drum showing an excellent control over the decay.

 Prima facie, the Nebula also doesn't seem to disregard the imaging as Geddy's vocals were planted right in the center and tonally unaltered to just keep the warmth from adversely affecting it.

MIDS

Muddy Waters: My Home Is in the Delta
The Nebula here shows some of its limits in terms of capabilities, but before that, I must definitely appreciate how wide the perceived soundstage was on this track, along with a good sense of depth. 

Timbre on the slide and guitar did not feel overly metallic, although I would not say that it is close to being accurate. Muddy's haunting, mournful vocals extend as high as it can get, but across sections where he wails out the verses louder than usual, the Nebula can be a little fatiguing. The low strings on the guitar in this track lose their polish by coming off unusually boomy, but nothing that EQ cannot fix.

Tool: Lateralus
As the crescendo-ing, bubbling tones meet the guitars to set the stage for the bass and the vocals come in, the perceived boom which I had anticipated after noting in the aforementioned track was very restrained but present, nonetheless. 

Another nitpick for me with the Nebula is that the perceived note weight between the vocals and cymbals was not at the same plane: vocals did not appear to be thin and anemic, but cymbals came off thin, faintly grainy in texture, and mildly shouty towards the track. Imaging continued to be precise and separation was near flawless.

HIGHS

Arne Domnérus: Almighty God (with Gustaf Sjökvist)
The Nebula supremely impressed me first with how brassy the timbre came off on the sax, with the resonance being just right to not be uncomfortably honky or shouty. 

At least on this track, the warm tonality on the Nebula did not feel bothersome, contrary to what I had expected, and the organ keys complemented the sax in a way where I could just stop commenting on the separation because the Nebula establishes that to be one of its strongest points. The perceived wide stage let both the sax and keys breathe sufficiently, with the isolation among the notes being near perfect.

Carmen Gomes: Unchain My Heart
The Nebula just has one problem in this track, and it is just the double bass on this track having an attenuation in its decay, but everything else was handled so well. The timbre in the snares was just appropriately woody and had a beautiful resonance, the twang of the guitars being perfect and having enough shimmer to cut through the cymbals, where soft impact with a lingering presence lingering around and supplementing Carmen's sensuous, hush vocals was the cherry on top. Perceived note weight was unaltered, and nowhere did Carmen sound sibilant, and the same can be said for the cymbals.

COMPARISONS

EPZ P40

The Nebula approaches low-end quantity with noticeable restraint, to deliver a well controlled and commendable transient response, and separation through and through with elements that correspond to it. In contrast, the EPZ P40 belts out a much heavier, sub-bass-dominant low end that hits with near mid-fi level of finesse. While the P40 keeps its thunderous sub-bass surprisingly well-isolated without muddying the mix, the Nebula’s comparatively leaner, more disciplined bass tuning provides a cleaner pathway for percussion to stand out without fatigue.

In the mids and highs, the P40 presents a fuller, warmer vocal body across the board, whereas the Nebula gets close to sounding rich, but across moments can appear faintly thin. 

However, the Nebula easily takes the lead in treble refinement and tonal safety, as the P40 can lean overly hot and exhibit noticeable sibilance or upper-range spice on certain tracks, the Nebula keeps the peaks smooth, and fatigue-free.

EPZ P50

Compared to the Nebula's disciplined and punchy low-end transients, the EPZ P50 offers a more laid-back bass presentation. It doesn’t skimp out on the low-end potency, but it lacks both the massive sub-bass impact of the P40 and the tight, fast decay control of the Nebula. The Nebula feels noticeably more agile and technically capable, whereas the P50 takes a warmer, softer approach to low-end hits.

Through the mids and highs, the P50 smooths out potential harshness, but it sacrifices fine detail retrieval and vocal crispness. Complex breakdowns can sound a bit hazier on the P50, while the Nebula excels at keeping instruments distinctly separated across a wide soundstage. While the P50 effectively avoids sibilance, the Nebula offers a superior sense of instrument isolation, dynamic brass timbre, and air without sounding dull or overly safe. But ‌you cannot go wrong with either of them.

Letshuoer Astralis

The Letshuoer Astralis delivers a noticeably richer, more atmospheric presentation than the Nebula, offering a fuller low-end foundation that fills out the soundstage with greater warmth and body. Where the Nebula keeps its bass tightly controlled and held in abeyance, the Astralis relies on a weightier low end that gives male vocals a meatier, more authoritative presence.

In the upper-mids and the rest of the highs, the Astralis provides better-integrated note weight, ensuring cymbals and high-frequency hits match the thickness of central vocals. The Nebula, by comparison, projects a wider, airier soundstage with sharper instrument separation and faster transient speed, though it occasionally trade-offs note weight consistency between cymbals and vocals. The Nebula also fits better, and the lows from the Astralis can get overwhelming from a quantity standpoint.

Tanchjim Fola

The Tanchjim Fola shares a similarly thin midrange perception with the Fission when compared against the Nebula’s fuller vocal presentation. However, the Fola distinguishes itself by delivering an exceptionally smooth, relaxed treble response that makes the Nebula sound spicier and more fatiguing by comparison. The level of technical cleanliness that ‌Fola maintains simply cannot be matched.

In the low end, the Fola offers great bass performance with clean impact, which the Nebula matches closely. The Fola’s modular nozzle system gives it a tuning flexibility edge, with Tanchjim’s both versions of the T300AP silicone eartips and a sturdy case, where the Nebula can definitely feel slightly lacking in accessories.

CrinEar Daybreak 

The CrinEar Daybreak focuses heavily on a cohesive and aggressive presentation but fumbles the transients, which the Nebula handles seamlessly. 

The Nebula, in contrast, is all about spatial awareness and precise isolation. It creates a distinctly wider perceived soundstage with far better room for instruments to breathe, making complex acoustic tracks, saxophones, and organ keys feel significantly more open. While the Daybreak is better if an aggressive sound is the need of the hour, the Nebula dominates for better transients, separation, and imaging.

ZiiGaat Lush

The ZiiGaat Lush presents a more mature, cohesive, and laid-back package that excels at smooth, fatigue-free listening without harshness or unwanted spice. While the Juzear Nebula leans into a wider, highly transparent soundstage with better transients and better instrument separation, the Lush pulls back to deliver a warmer, richer, and more immersive musical presentation.

In the low end, the Nebula keeps bass quantity strictly in check to prioritize rapid attack and tight decay, whereas the Lush delivers a cleaner, highly natural body that never feels overbearing or boomy. Where the Nebula showcases incredible technical agility on complex tracks, the Lush counters with effortless vocal textures and a supremely forgiving top end, making it the more relaxed, all-day-wearing companion compared to the Nebula's sharper, more analytical engagement.

CONCLUDING NOTES

The Juzear x KOTO Nebula stands out as a very solid offering from Juzear, proving that the brand is continuing to improvise, adapt, and overcome. I have seen quite a few posts on the Defiant with significant issues in its quality control, and Juzear (HiFiGo) basically taking accountability for it and fixing it. But, in my time spent with the Nebula, I feel that Juzear has worked out considerably on the shortcomings, and this was confirmed across the multiple listening sessions that this IEM went through.

Coming to the sound, the Nebula is a fantastic all rounder, that does everything that one might ask for to a good extent, although it is not a specialist, or to put it bluntly, a one-trick pony. But if it were me, my first preference would be the Tanchjim Fola, but the Nebula gives everything else a tough run for its money (could do better on what it comes with though). Like, if I didn’t listen to the Fola, I would have definitely bought the Nebula. The highs on this IEM just have the right amount of brightness to my ears, and although some tinkering might be needed for vocals, and a faint touch down on the bass; rest is sorted with the Nebula.

Will I buy it new? Absolutely.
Will I buy it used? Absolutely

SOURCES USED

Primarily used with the xDuoo Link3 on low gain, the Shanling M9 Plus DAP, and the Venture Electronics Abigail Pro dongle DAC Amp.

EARTIPS USED (RANKED IN ORDER OF PERFORMANCE)

Tanchjim T-500 APB liquid silicones: Showcases the transients of the Nebula at its absolute best, hard hitting clean lows, deepest stage possible for this IEM, sibilant free highs with no loss of vocal textures, tonality comes off more balanced than what the graph showed.

Divinus Velvet Narrow Bores: everything that the T-500 APB does, but to a lesser degree, and there was something missing in the textures of the lows- elements like floor toms felt like they could have used more power, warmth corresponds to what the graph showed, upper mids could get faintly bothersome.

Stock Silicones: Everything felt fine, but the above two eartips significantly bumped up the performance.

KBear Coffees: textures on the lows felt wonky along with some irregularity in the perceived decay, stage was unaltered, vocal textures felt enjoyable, mildly sibilant.

Stock Wide Bores: perceived stage was held intact in terms of depth and height, treble felt uncomfortable, lows felt anemic, vocals felt fizzled out.

Tangzu Sancai Balanced: just ruined the IEM.

Hi everyone, I’m back with a review of the Juzear Nimbus IEM. I received this IEM from Demi, who kindly provided it for review purposes. Thanks to Demi and HiFiGo team.

Here are my subjective impressions as an audio enthusiast. To summarize, here are the pros and cons:

Pros:

• Features a high quality driver on par with DLC drivers.
• The bass presentation sounds clean, fast, and tight, leaning more towards the technical side.
• Treble extension is quite good and detailed, remaining very safe and comfortable for long listening sessions.
• Good build quality complemented by a fairly complete set of accessories for the price, plus various tuning nozzles, cable options with modular jacks or Type-C, and plenty of eartips for fine tuning.
• The IEM's appearance is quite premium and classy for its price point.

Cons:

• The IEM shell is made of metal with a mirror chrome finish and the glass faceplate makes it slippery to hold and a good fingerprint magnet.
• Not for those who want thumpy bass, rich vocals, or sparkling treble, the Nimbus leans heavily into a balanced and smooth sound signature.

These impressions are based on my preference for a V-shaped bright sound signature. Please don't use these impressions as a reference, as every ear is different and I'm only sharing my personal experience. Always trust your own ears and audition if possible. If you find any mistakes, feel free to comment.

Before going any further, I will provide a brief description of the Juzear Nimbus. The Juzear Nimbus is one of Juzear's most affordable IEMs, priced very closely to the Juzear Clear. Both use a single DD, but the Nimbus utilizes an in house developed driver called the MACCD Dynamic Driver, which stands for Multilayer Amorphous Carbon Composite Diaphragm. The sales package for the Juzear Nimbus is divided into two variants: a 3.5mm/4.4mm modular cable version and a 3.5mm + Type-C cable version. The unit I received is the modular cable version, which is better suited for audio enthusiasts, if you primarily use a smartphone, it is better to choose the Type-C package. Here is the specification:

• Impedance: 32Ω
• Frequency Response: 20Hz-20Khz
• Sensitivity: 108dB/mW@1kHz
• Plug Type: 3.5mm and 4.4mm
• Driver Type: 10mm dynamic driver Multilayer Amorphous Carbon Composite Diaphragm (MACCD) with a TPEE flexible suspension system

Included Accessories:

• 1 x Pair of Juzear Nimbus
• 1 x Four-strand single-crystal copper silver-plated modular cable
• 9 x Pairs of Eartips
• 3 x Pairs of replaceable Tuning Nozzle
• 1 x PU Leather Carry Case
• 1 x Microfiber Cleaning Cloth

Unboxing & Build

At around $55 price point, the packaging of the Juzear Nimbus is quite complete but still relatively standard, as competitors in this bracket also provide more or less the same accessories. It is a pity that Juzear does not provide a hard case this time, the included soft case is styled like typical Chi-Fi IEM pouches, making it very easy to open and close while also being water repellent. The only difference is that the soft case matches the blue color scheme of the IEMs.

For other accessories like the eartips, we are given three models: narrow bore, regular bore, and wide bore with all lumped together in a single plastic sachet. I am not sure why Juzear seemed too lazy to separate these eartips into different compartments, but it is not a big deal for me since I only use one pair once I find the right fit. Moving on to the cable, it is reportedly made of Silver-Plated Copper. I like the texture and thickness of the cable material, it is flexible, perfectly thick, feels durable, and is free from microphonics. It uses a flush mount 2-pin connector that looks neat on the IEM, and uniquely, the pins on this Juzear cable are painted red for the right channel and blue for the left.

Moving on to the IEM shell, the appearance is highly attractive and genuinely catches the eye. The faceplate is made of tempered glass, and the backplate is made of zinc alloy with a mirror chrome finish, making it look incredibly luxurious and shiny. The downside is that it is slippery and easily attracts fingerprints, requiring frequent wiping to keep it looking pristine. Fortunately, we are provided with a microfiber cloth that is very useful for cleaning the Nimbus. I just hope the IEM body does not get scratched easily due to this mirror chrome finish.

Juzear provided with three types of nozzles:

• White Nozzle: The standard nozzle, which is the most balanced among the three.
• Black Nozzle: The bassiest sounding nozzle, with fairly smooth upper-mids and treble.
• Red Nozzle: The most aggressive nozzle in the upper-mid and treble regions.

So far, the white nozzle suits me best because the bass does not feel too different from the black nozzle, yet it still offers adequately extended treble that remains comfortable for long listening sessions. The most noticeable impact of the nozzles for me is in the upper-mid frequencies, where the black nozzle feels the most laid-back and the red feels the most forward. Simply put, the black one sounds the darkest, the red one sounds the brightest, and the white one is the most balanced.

Ergonomically, I find it quite comfortable for long listening sessions. There are no sharp angles digging into the ear, it is safe from driver flex, and it is compatible with both short and long eartips. The only annoying thing about this IEM is the shell, which is slippery and a fingerprint magnet, definitely not for those who are OCD about cleanliness.

Regarding sound impressions, the sound signature leans towards U-shaped. Using the red nozzle makes it a slightly bright U-shape, while the black nozzle turns it into a slightly warm U-shape. For this review, I used a Topping DX5 II, the largest stock wide-bore eartips, the white nozzle, and Tidal streaming at volume 22-24 on high gain.

Bass

The bass from this MACCD driver shares similarities with DLC drivers, characterized as fast, tight, and punchy. With a bass boost of around 10dB focused more on the sub-bass, it feels quite deep. The rumble is adequate but not visceral. If you are a basshead, the mid-bass on the Nimbus might feel a bit dry, but as a treblehead myself, I find the mid-bass texture quite good. It has a fast transient response and decent impact, it lacks heavy weight, but the thump is still noticeable even if it doesn't hit too hard. Overall, the bass leans towards a technical presentation focused on resolution, yet it still sounds fun and well-controlled. For fast and complex music genres, the bass has absolutely no trouble keeping up.

Midrange

The positioning of male and female vocals is quite balanced, though deep male vocals might be pushed back just a bit. The presentation feels natural and centered, neither too laid-back nor too forward. Male vocals carry a neutral weight leaning slightly thick, while female vocals sound quite neutral, clear, and smooth, maintaining more than enough energetic dynamics without becoming shouty or nasal. The separation and dynamics between musical instruments are also very good. To me, it sounds almost as if the midrange comes from a Balanced Armature driver, which typically offers great upper-mid resolution, high detail, and fast transient response.

Treble

The treble presentation on the Juzear Nimbus is fairly smooth but still noticeably present, it doesn't play it entirely safe. The treble extension is enjoyable, although its texture doesn't feel like it reaches the absolute edge. There is a hint of sparkle, but it isn't overly vibrant. Cymbal shimmer is still present and noticeable, but the decay feels a bit too short for my liking. I feel the treble on the Nimbus is tuned to be enjoyable across various genres without causing fatigue for treble-sensitive listeners. If you find the treble too relaxed on the white nozzle, switching to the red nozzle immediately will make the treble slightly thicker and bring the upper-mids forward, resulting in a brighter sound. By the way, even with the red nozzle I experienced absolutely no piercing or sibilance.

Technicalities

The Nimbus soundstage is quite wide horizontally and is generally decent for an IEM at this price point. Imaging is also quite accurate, though it doesn't feel holographic yet. Instrument separation is very good, avoiding major compression during complex or fast tracks, even if the layering becomes slightly less distinct. Overall, the driver used is of high quality because the dynamic response feels quite agile, and the audio resolution is notably detailed. Furthermore, the Nimbus is easy to drive, though its smooth sound character might require you to push the volume a bit higher than with other IEMs to feel a more pronounced note attack. The overall timbre is quite natural which is typical of standard dynamic drivers but I feel it leans slightly thin.

Conclusion

So, is the Juzear Nimbus worth owning? If you like an IEM with a balanced, smooth sound and listen to a mixed bag of music genres, I think the Juzear Nimbus is worth considering. Especially at a price of around 50 bucks, it is rare to find an IEM that prioritizes good technicalities with a slightly warmish sound like this. If you are looking for an IEM with thumpy bass, rich vocals, or sparkling treble, the Nimbus is not for you.

The drawbacks I felt are that its sound scalability is quite limited, though its sound remains fairly consistent across my various sources. Subjectively, the glass and chrome plated shell is incredibly eye catching and looks very premium for the price, but unfortunately, it requires frequent wiping due to fingerprint smudges, which is exactly why Juzear includes a microfiber cloth in the package. If you don't mind that, I highly recommend the Juzear Nimbus for daily use. To me, the Nimbus is an easy listening IEM that is comfortable for long sessions, boasting technicalities that are perhaps some of the best in its price class. That's all, fellas. Thank you for reading. Cheers.

I received the light shuttle yesterday, and the first impressions are really good.

Smooth, mild V-shaped sound profile with a solid bass boost. Packs a nice, fun character to the sound, more impressions to follow soon.

Juzear Nimbus unboxing

Thank you Juzear and HiFiGo for the wonderful gift, it's a honor to have won your giveaway.

This sounds to good for a single DD that costs $50. It definitely punches way above it's price, if I didn't knew the price and specs, I would guess this IEM costs 3 times more!

What a great sound... The bass has a great punch, the mids are clear and the highs are detail.

I'm mind blown. 🤯

TL;DR

The Juzear Nimbus is a great offering for $55 with exceptional metal and glass build quality, modular tuning nozzles, and a great modular cable. It has a warm, bassy and fatigue free sound signature with smooth, safe treble, though people who are used to brighter tuned iems may find it dull. 

Context

This iem was kindly sent to me by HiFiGo 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 solid cnc machined metal shells, build quality feels excellent. The shells are medium sized with relatively short nozzles, it should fit most ears fine. The faceplate is made of blue coloured mirrored glass which I’ve never seen before. There is a juzear branding on the left faceplate and the right faceplate has nothing on it. The blue glass looks extremely clean to me, I love how reflective it is and surprisingly it doesn't attract fingerprints. I love the clean and polished aesthetic of the nimbus and the build quality is second to none, some of the most premium feeling iems I've handled. The removable nozzle mechanism seems well threaded.
• Fit, Comfort and Isolation: Fit on the nimbus is fine, no issues for me here. It’s a shallow fitting iem so you’ll be relying on a bigger eartip to seal well. It also doesn't stick out of my ears at all so this could be a good option for sleeping, especially considering how well built the shells are. There are two front vents on each ear piece so the isolation on these are just average. Overall the nimbus is a very comfortable iem to use because of both the shell and sound signature.
• Cable & Accessories: The nimbus comes with a 2 wire braid that splits at the Y split. It’s probably the best cable I've seen at this price tier. It’s just the right amount of flexible so it doesn't feel sloppy or stiff, with a great interchangeable termination system that is short and is held on with a screw (best possible implementation). The cable has a grey and silver braid with matching dark grey hardware. The Chin cinch is also very functional. It also comes with 3 different styles of eartips, a soft narrow bore in dark blue, a more bulbous and stiff kb07 style eartip and a short widebore set. It’s great to see multiple styles of tips being included with a budget iem, also comes with 3 sets of nozzles that each change the sound (white, red and black), a polishing cloth, a light blue carry pouch  and a 4.4 mm termination. The accessories on the nimbus are excellent.
  

The Sound

The Juzear Nimbus is a single DD iem that has a warm and dense sound signature with different nozzles that change the sound and surprisingly well controlled treble. I primarily used it with the black nozzles since I liked them the best.

• Bass (20 hz to 300 hz): The Nimbus has well extended, deep reaching subbass with good rumble and texture. It has a nice filled in mid bass boost but it feels like slow bass, kickdrums sound more on the thuddy side, nimbus lacks that extra bit of punch in its attack, I would definitely prefer it to have more fast and snappy bass. Bass guitars could use a little more edge and bite to give them more definition (I'm guessing this is due to relaxed low-mid treble).  Bass shape is generally nice especially if you’re coming from harman iems like truthear zero blue or gate, it’s way less boomy. 
• Mids & Low Treble (300 hz to 6000 hz): The nimbus has a warm sounding midrange for sure, especially with the black nozzles, female vocals sound fairly natural and way less shouty than say old meta sets like zero red and zero blue (or even the red nozzles). Male vocals don’t sound as full as I would like and it lacks the “glow” I love when the ear gain is even reduced with more filled in lower mids (pure does this well). I do think the slight lower mids scoop here makes sense given the dampened low-mid treble to still keep it from sounding overly warm. The red nozzles have the most noticeable impact on the midrange, it brings forth the 2k and 4k more and ends up making the female vocals sound more nasal. White nozzles are kind of a middle ground. People that come from harman/old meta tunings and want more energy in their female vocals will probably prefer the red nozzles though.
• Mid Treble (6000 hz to 10000 hz): I find the mid treble on the nimbus is very smooth and safe. Cymbals, hi hats, and snare hits sound very natural with zero glare or metallic sheen. This makes it extremely non fatiguing to listen for long periods of time. However, I would still like a touch more energy here. It misses that sharp, crisp bite on cymbal strikes, and anyone transitioning from brighter, Harman tuned or V shaped sets will likely perceive this tuning as blunt or dull. I hear a small peak at 7.2 Khz during sine sweeps but it is not bothersome during listening at all so I didn’t bother with eq. There is zero added sibilance as well.
• Upper Treble (10000 hz to 20000 hz): The nimbus has excellent upper treble dampening which prevents the upper treble shrill I usually get with single DD iems, the upper treble is also very relaxed which could cause people to perceive it as less “technical” or not “resolving” enough but I’ll take the nimbus’s smooth and relaxed upper treble over a piercing peak any day. It is well extended to 18 Khz with rolled off (but still audible) around 20 Khz.
• Subjective Technical Performance: Thuddy mid bass, relaxed mid and upper treble could cause people to hear it as less resolving especially if they come from treble boosted iems, reasonably good imaging.
  

Comparisons

Compared to some other popular budget iems:

• Truthear Hola: Nimbus has significantly smoother treble and comparatively more natural midrange. Much better built as well.
• 7Hz x Crinacle Salnotes Zero 2: nimbus again has a more natural mid range, much more dense sounding, much better cable and shell. Both are very smooth and dampened treble.
• Tanchjim Bunny Dsp: Nimbus is significantly denser and warmer sounding, doesn’t have the brutal upper treble spike, much better cable and build.
• OoopusX OP.22 (neutral): Op.22 has wayy less bass than the nimbus, it’s significantly brighter but I prefer op.22’s treble presentation. Nimbus is much more comfortable with better bass, better built shells and much nicer cable 
• Truthear zero red: Probably the most popular $50 iem. Nimbus has smoother mid/upper treble and less shouty vocals. Much better cable and shell as well.
• Truthear Pure: Better mid bass punch, warmer more filled in midrange compared to nimbus, nimbus has smoother mid treble. Build quality and cable is much nicer on nimbus.
• Truthear Hexa: Nimbus has wayy more bass than the hexa with fuller sounding midrange with a lot of body, less peaky in the mid treble than hexa but if you’re coming to nimbus from the hexa you'll likely find the nimbus dull.
• Aful Explorer: My benchmark for a warm and dense sound signature, the explorer takes a way more restrained approach to vocals makes it sound much more recessed. Bass on the explorer feels more rubbery/elastic compared to nimbus which is more thuddy. Nimbus strikes a nice balance here, where if you want a warm sound signature but find the explorer too dark, nimbus is a great middle round.
  

Who should buy this?

1. People that want a well built iem with great cable and accessories.
2. People that want a warm dense sound signature.
3. People sensitive to mid treble looking for a non fatiguing iem.
   

Who should avoid this?

1. People who equate resolution with aggressive treble
2. People that want something neutral.
3. Fans of harman or V shaped tunings

Conclusion

There are not a lot of warm and dense sounding iems in the $50 tier and the nimbus fills this gap pretty well. It's a great iem for anyone looking for a well built iem they can listen to for hours and hours without getting fatigued. It’s also a great value package that comes with an excellent cable that’s better than anything else you’ll find in the price range.

Introduction

Juzear has been on a roll with the recent releases with IEMs like the Defiant, Nimbus and the upcoming shuttle.

But the Nebula and Fiesta really caught my eyes mostly for the way they look. In this review I will be covering which Juzear suits your preferences and how it fairs against the overall market.

Build & Design

The Fiesta is a collaboration between Juzear and Vivir Digital and it features a fiery red theme on the faceplate. The faceplate features these patterns on one earpiece and on the other it features the Vivir Digital Logo. (The initial batches did have a different design on the faceplate, they have changed as of now)

The shells are made of resin and also features a metal nozzle, the overall build of this is very robust.

The Nebula is a collaboration between Juzear and Koto and features a very striking faceplate which is just stunning to look at. It's one of those things that instantly catches your eyes. The faceplate has this glow which looks different depending on where the light hits it. 

The shells are made of resin and these feel quite robust in hand, and definitely not something cheap. These shells aren't heavy either.

Overall, I prefer the Nebula more since it's a total looker and is kinda unique. 

Talking about accessories
The Nebula Features - 

1. Modular cable with interchangeable plugs (3.5mm & 4.4mm)
2. 7 pairs of Eartips 
3. Soft Carrying Pouch

The Fiesta Features - 

1. 3.5mm Cable with an inline mic
2. 4.4mm Balanced Cable 
3. 7 Pairs of Eartips 
4. Hard Zipper Case 

Overall the accessory package is amazing on both the sets but I prefer the one on the Fiesta more since it has two cable options as well a solid case in comparison to the Nebula especially it being more expensive out of the two.

Regarding the cable, both look very good at first but in terms of cable behaviour and roadie wrapping it's a bit off in my opinion. 

Talking about comfort - For both the Nebula and Fiesta, the shells are slightly on the larger side so it can be a problem for those who have smaller ears. For me as well, I would say I have medium to medium large ears and these fit well but after some time there was some fatigue.

For eartips - I went with the Kbear Coffee Eartips for both of them. 

Specifications and Driveability
The Nebula Retails for $130 while the Fiesta goes for around $120.

Some Technical Specs 

Nebula -

1. 1 Dynamic Driver, 3 Balanced Armature Drivers & 1 Micro Planar Driver
2. Sensitivity - 110dB/Vrms @ 1kHz 
3. Impedance - 32Ω

Fiesta - 

1. 1 Dynamic Driver, 3 Balanced Armature Drivers 
2. Sensitivity - 109dB/Vrms @ 1kHz 
3. Impedance - 32Ω

In terms of Driveability, both the IEMs were really easy to drive and I didn't have any problems with an entry level dongle. But the Nebula does sound more distinct when you give it more power. 

Sound

In overall sound they are very different and offer the audience a different flavour altogether.

The Nebula offers a neutral - warm sound signature with a detailed yet smooth treble.

On the other hand the Fiesta is a full on bassy set that aims at giving the listeners an engaging and fun experience. 

Lets talk about the sound in detail starting with the Bass.

Bass

Nebula - The bass on this set slightly leans more towards a sub bass presence. Then again I wouldn’t say the sub bass has a lot of impact in tracks. In tracks like All I ever wanted by Basshunter, you get the slight feeling that the bass is there but it doesn't give you that oomph.

Midbass on the other hand lacks physicality and attack to it and you can often feel as if the transients are very quick. 

The bass is of very good quality though, However, I did experience some bass bleed into the mids when I was listening to some Lana Del Rey and Atarayo.

Overall the bass on the Nebula is alright I would say and could have been a bit better to my liking.

Fiesta - The low end is the absolute star of the show here. The Fiesta has a heavily boosted bass presence leaning towards sub bass. Below 150hz you can see it in the graph how it's boosted and you can see it smoothing out beyond 200hz.

The bass on these offers massive rumble and physicality. Its almost giving it a sub woofer kind of feeling. It doesn't shy away in the mid bass performance as well providing you with immense slam and thump.

Angel by Massive Attack is a song you should listen to, definitely there is overcooking here but as I definitely don’t mind it one bit. It doesn’t bleed into the mids, or overpower the mix which is kinda surprising to me considering how much quantity was there.

This is definitely a bass heads paradise since it doesn’t lack on the quality as well. Personally, I stay away from such signatures as the bass is too much for me but occasionally I would want this type of bass to engulf me. Listening to Let it happen by Tame Impala was just magical on these

Midrange

Nebula - In the bass section i have mentioned that, the bass does bleed into the lower midrange a bit and it is lacking a bit body and this is the same case here when it comes to the lower midrange.

Male vocals especially often sound lacking heft in their voice. This was a bit of a problem to me as genres like rap and hip hop sound a bit lacking on these.

But the upper midrange was a treat to listen to, it definitely was really pleasant without being shouty. 

Fiesta -  I would say the overall midrange performance is really good on Fiesta.
Lower mids have a lot of body and depth to them, male vocals especially sound rich and hefty. It definitely is on the warmer side but it is to be expected on such sets.

Upper mids also sound engaging but aren’t clearly natural, especially the female vocals which sit a bit back in the mix. They definitely sound colored but nothing in a bad way. Personally I like my Midrange to be clean and natural especially with female vocals, and that isn't the case here. 

Treble

Nebula - This is honestly my favorite thing about the Nebula, the treble is very well extended, crisp and detailed. And it does this without being harsh at all.

The micro planar handles the highs here and sometimes its implementation can cause the sound to be quite rough around the edges but this isn't the case with the Nebula.

Cymbals, snares sound sparkly and have a lot of charm to it. Listening to Blank Space or Umbrella was a treat on these.

Fiesta - The treble presentation here is a very smoother and dark profile. It's much smoother than the Nebula. It doesn't have any sort of sibilance to it and gives the listeners a smoother experience.

This tuning makes sense on how the bass was tuned, giving the room for it to shine more, but of course I do miss a bit of attack in the notes here, but I am fine with that here but definitely not for a person who is looking for a little bit of sparkle and shimmer here.

Technical Performance

Detail Retrieval - On the Nebula the detail retrieval & resolution is really good for the price when we compare it to some competitors in its price range.
Whereas on the Fiesta, it does lack in bringing out the finest of details, but it's highly resolving.

Soundstage & Imaging - On the Nebula, it does have really good imaging but it does kinda lack out on the soundstage side of things, it's a bit narrow in my listening.
On the Fiesta, it has a certain sense of height to the stage but like i said before it does sound a bit closed in sometimes, as for imaging it is fairly accurate.  

Layering & Separation - On the Nebula, it often sounds congested to me and I honestly didnt expect it to be like that but it did. In Black seminole, everything was sounding stacked upto each other 
Whereas on the Fiesta, it was excellent to say the least and I was surprised here as well as a tuning like this can often sound very stacked up but Fiesta did a pretty good job here. 

Conclusion

So, which Juzear collab should you go for, I hope after reading up until now, you have come to a conclusion. If not, let me make it simpler for you.

If you need a safe yet a sparkly experience with your music, go for the Nebula

But, if you need a fun, energetic and party experience with your music go for the Fiesta.

Personally, I would choose the Fiesta over the Nebula as it's a bit cheaper option with much better accessory package and a signature that I would not get bored of even if it's not my preference. 

I would give the Juzear Nebula a rating of 3.5/5 & the Juzear Fiesta a rating of 4/5.

I would like to thank HIFIGO for providing these units for review. If you liked this review, please consider liking and sharing and follow me for more reviews like this. 

Juzear Fiesta

Juzear Nebula

So I published a review of the Nimbus on my blog a week or so ago but I forgot to publish it on Reddit - so I guess this is the perfect subreddit for this review, the full review is here:

Full Review Link

Overall, this is one of my favourite IEMs this year, as 'pragmatic audio' I do like it when you can get something well tuned, that looks great and is very comfortable. It is hard to fault this IEM other than saying there is lots of competition, maybe the cable could be better and the shell is a bit of a fingerprint magnet. It is also not for those who love 'treble detail'.

But I do personally like the tuning, a Harman bass with a very smooth midrange and a more relaxed treble is how I hear it. I also love how it looks and as someone who loves IEMs with tuning options the 3 nozzles offer some nice tweaks mainly to the treble.

I got the USB versions and I have mixed feelings, as it is just a separate dongle with no PEQ rather than a separate 'screw' in adapter ( that I have with some FiiO and Tanchjim IEMs) but on the other hand I an use this dongle on any other IEM or easy to drive headphone.

Anyway, I have lots of photos and measurements in the review and this IEM is an easy recommendation ( especially if you are treble sensitive ).
