Really wonder how is the bass on ZEX Pro, what is the amount of bass, specially sub bass and how bass compares to regular ZEX, ZSX, DQ6, Blon 03 and 01, also how is the soundstage and instrument separation, is it more neutral or V shape tune. Commercial graph looks weird, but KZs graphs never represents true sound and how it actual graphs. Hope by adding 30095 BA it did not bring this popular and unwanted KZ's metallic sibilance. I think it is a good thing thought that BA is at the top, behind other two drivers and not in the front or in the nozzle.
Love to see a GREAT first impression on a newly released model. Would also like to hear some comparisons. Was there anything that WOW you during the listening? Does the micro-detail stand out from the rest?
I'm holding it for now after another 2 IEMs + 3 cables ordered past week. You know, one KZ at a time.
Still very early on since I just got them, but will try to share some more impressions so far since the promo price is still active as of this post it seems.
Bass quantity to me seems maybe slightly lower than the NRA/ZEX in the mid bass region. especially in the BL03 which has a lot of it. But it's relatively tight sounding and well controlled to me. Nice enough thump when the track calls for it, and nice enough texture too. Soundstage is average to me, but to me, most IEMs are more or less in that category for me, and will always lose to earbuds.
Instrument separation and detail retrieval I think is above average for the price, and if you got it at the 22USD price, it's even more value for money in that regard I guess. The ZEX and NRA i felt already punch above their price for detail retrieval, and this is maybe a small step better I think. But still not going to beat more expensive sets though. (like i think my smabat proto 1.0 and ER4XR still has better technicalities) Haven't heard the DQ6 though, and gave away my ZSX long ago, so can't compare.
Tuning wise probably more of a mild V-shaped. Mids are still slightly behind the treble and bass to me. They are still a bit on the thinner side though. Male vocals seem a bit thinner than even the NRA probably since less mid bass, but upper mids have more presence and body to me, and overall, mids sounds better on the ZEX Pro for me. Compared to BL03, more or less same thing. More body overall, more forward. so prefer the ZEX Pro over those. Slight sibilance for certain vocals and tracks (like if I go look for it in tracks i know are more prone to sibilance it's there, but it's not too bad or unlistenable to me). Shouldn't be a problem for most. Pretty safe tuning overall that isn't shouty, too harsh, or fatiguing to listen to for me. To me, just the shift in the upper mids to a bit further back to 3kHz makes it better for me already. Don't hear that much of a metallic timbre though, but it's also not quite the most natural I've heard either? Slightly tizzy in the cymbals.
Overall... not so much of a WOW factor for me, but more like pleasantly surprised that the bass quality has been slightly improved and that the mids are nicer too, and fits my preference more. The treble region kinda still reminds me a bit of the NRA/ZEX, so feel like most of the changes could have just come from the DD driver used and by tweaking the frequency response a little. Maybe the BA driver is contributing a bit to that better mids, but my completely unscientific guess is that it's probably not doing all that much. But I'm not quite willing to tear it down and disconnect the BA driver or whatnot, and i got no way to measure the FR anyhow, lol, so I'll believe that it's the former for now.
at the promo price now on AliExpress, it's a pretty easy recommendation for me since there is so little I don't like about it. Inoffensive sound and tuning, technicalities that punches above its price bracket too. Like it more than the recent TKZW Wave, TRN TA2, CCA CA16 pro too. But if you're a bass head, or you already have something better, the ZEX Pro doesn't really do anything special in terms of sound. To me it's just a good value for money for the amount of performance it offers at this price point.
