hum, yes, the TANCHJIM OLA grow on me.
ill be the black sheep about those I guess.
simply put: technicalities are insanely good in sub-100$ price range.
There you go for my first impressions:
TONALITY: 7.8/10
TECHNICALITIES: 8.8/10
CONSTRUCTION-COMFORT: 7/10
SOUND BENEFIT: 8.5/10
OLA, a mature vivid sounding IEM with crazy technical performance, severe tonality and extreme clarity.
OLA, tuned by ASANO TANCH, tuner of the OXYGEN. (edit: seem like this assumption is BS....)
OLA, the polar opposite of Tanya. Anti-coloration, anti bass warmth and rumble, anti-thick timbre.
OLA, in my case, need brain burn in to be fully enjoyed, as well as finding the right ear tips to get a secure fit and open sound.
OLA-NALITY= Bright neutral with hint of extre mid bass punch, high level of transparency and sharp and textured treble.
TECHNIC-OLA-LITIES= Extremely good, fast snappy attack, excellent resolution and transparency with rich nuanced texture, imaging with rich layering and crisp positioning. Real mind blow here, i need to compare to HZsound Mirror but these might be in similar league, timbre seem to have more micro details in texture for ex and sound is a bit less flat and more holographic.
OLA TIMBRE= even if I praise it, it have a slight metallic edge to it sometime, it's a bit thin too and brightish-dryish, this is is a timbre to charm your ears it their to extract presence of every sound info.
BASS: This is were the sword hit, it will be hate-love affair, its just a hint boosted in mid bass so kick do have weight and energy, minimal, that permit to keep everything clean. Here the texture work better since it embrace bass roundness. Sub bass is there (once you got the right eartips) and produce minimal rumble, qui similar to HZsound Mirror in that regard, for ex, with track Moonlight from IAMDDB you can feel the sub bass density but it's articulation is a bit flat, still, it permit to be well separated from the punchy kick. This is what is phenomenal here, how the sub-kick and mids are perfectly articulated and separated. Its a versatile ''unfun'' bass, it do well with acoustic bass in jazz trio even if i would love a bit more resonance and body.
MIDS: Hum, crisp and transparent, light in weight, piano note are fastly rendered, clean and clear but lacking a bit in lead attack and resonance, 2 things that can interfer with clarity in busy track so here the OLA deal like a champ. We have more texture than density and warm. Female vocal are suprisingly full and well rounded though, very beautifull and fowards yet non sibilant or artificial. In fact, it might be the most natural part of sound rendering of OLA: a female vocal lover IEM.
TREBLE: Fast, energic, between dry and airy and very generous in micro-details even if it doesn't feel unbalanced or overly an analytical. Sometime it can go a bit hot (especially at high volume) so cymbals splash will sound a bit harsh and shouty. I would have love a bit more brilliance and sparkle, for ex the harpsichord of Pierre Hantai sound a bit dry and lacking in natural decay, but he play so ****ing fast that at least the OLA can keep up with it's performance, never mixing notes in a messy resonant way. But lack of note weight and sparkle make it hit or miss depending of harmonic range he play. So, a hint clinical too is the treble.
SOUNDSTAGE is deeper and taller than wider, and I highly suggest to use KZ STARLINES eartips to not make it overly intimate.
IMAGING is excellent as stated in technicalities section, since we have both transparency and crisp resolution, the mix of transparent sound layers and static instrument positioning is way above it's price range here.
CONCLUSION
Asano Tanch know how to tune reference sounding IEM with mature tonality, high level of resolution and near unseen technical performance for the price. This IEM will impress more the hardcore audiophile than does that search for colored and charming musicality with warm natural timbre or fun soundsig with extra bass. It's an IEM that can grow on you when you feel like going critical listening, it's not a boring one, in fact, it can be perhaps fatiguing for some treble sensitive people since its very energic and lively.
Anyhow, this is an audacious tuning choice from Tanchjim that might pay in the long run since their no other IEM with this very tonality wtv price range I try...
These OLA deserve respect, even if the musicality is unforgivably severe.
