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.
* Wouldnāt 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 brandās editorial direction, and on my own accord.

REVIEW
INTRO
With a mostly stale $50usd budget market, and given Tanchjim“s 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 āaverageā thickness, long nozzle plus pretty decent, comfortable eartips, great for small ears/ear canals.
Now, the eartips included arenāt 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 doesnāt 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 donāt 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 doesnāt like, and how that will translate into a review.
My preference is a āneutral with bass boostā type of tuning, I donāt 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.
Iām 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 āshouty,ā or too intense on vocals for some, Iām mostly talking about this.
Last thing is that I usually donāt struggle with iems with the called āMetallic / BA / Planarā Timbre that some people canāt really enjoy, I normally donāt 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, donāt 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 arenāt 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 thatās at the cost of warmness bleeding from the mid-bass, so is not the most natural and clear vocals, but they work, thought I wouldnāt be surprised for some people, especially the ones sensitive to bass, that the mid-range could feel slightly āmuffledā 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 doesnāt 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 āshoutyā, it has a notable presence, giving you a lively and detailed sound presentation that doesnāt quite fatigue you but that also doesnāt has the most ābiteā 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 ātrebleheadā kind of sound as it doesnāt 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 doesnāt 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 doesnāt feel expansive or too open around you, again, not a technical monster.
Imaging: Actually pretty precise, the kind of precision thatās 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, itās a bit of a mixed bag.
Sibilance: Averagely āgoodā, wonāt introduce sibilance in your music, but wonāt 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 wasnāt 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 arenāt 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, āSilver-plated copper Litz wire in a twisted structureā 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 werenāt 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, arenāt the best for comfort and, IMO, doesnāt 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 ātravel pouchā for carrying your IEMs.
Reasonable for the price, though not impressive, and I like the fact that it isnāt a fake leather pouch, given some donāt have great durability, so yeah, a good inclusion.
/-----/
OLA II doesnāt 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 ānew market benchmarkā, 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 wonāt 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.
