wow so you got the new Z1 already! i thought they are still in pre order state? so how the Z1 compared to their wired IEM? Im interested like I said on KZ thread, they have more sub bass and thicker than overall TWS currently with their 10mm driver. How is the bass decay speed and texture? SQ is priority for me rather than other features
seems like my instinct were right, they have ZSX signature sound? of course with less separation and technicalities. How is the soundstage and imaging?
and that very fast, i thought they are still in pre order session? now Im interested.. ugh
Will just combine the Q from KZ thread too. haha. I got these from Linsoul a little earlier for review. Probably helps that shipping from China to Singapore is relatively fast. haha. It's one of my favourite sounding KZ to date, though admittedly I haven't really tested that many of their IEMs (only ZSN Pro, ZS10 Pro, ZSX, EDR2) aside from their wireless stuff (T1, S1, S2).
For me the tonality is what I like the most? Because it's a single DD, there is almost no steely treble at all. ZSX was better than the others, but still a tiny bit. Technicalities it loses out to ZSX of course. Sound signature i think it's close? I don't have the ZSX to compare anymore, but I have the same general impressions as I did with the ZSX, which is just how balance the bass, mids, treble are being presented. They are all present and forward sounding and doesn't overpower one another. Though on the ZSX i remember it was a little fatiguing for me and i ended up needing to tone down the 8-9KHz a little, and then it was fine for me. For the Z1, i don't have to do that. ZSN Pro is basically not even worth mentioning compared to the Z1 since the treble is just.. not great. Steely, sibilant, intense. haha. ZS10 Pro fares a little better, but still not a fan of the treble. Personally I value tonality a bit more than technicalities.
for the bass, it's nice actually. I was a little afraid looking at their graph that it would be overwhelming, but it's punchy and thumpy, and doesn't sound too bloated or boomy. I'm listening to caravan from whiplash soundtrack and it has a lot of fast and repeated bass drum beats, especially near the end of the track and it sounds pretty good to me. Sub bass is definitely one of the more substantial I've heard on a pair of TWS earbuds, and I think it's pretty well done too. The sub-bass quantity reminds me on the dual DD AKG earbuds that comes with the Note10, but I didn't particular enjoy that as much since I find the mid bass a little bloated.
Texture wise, it's relatively smooth sounding I guess? Though not to the point where it loses too much definition? I'm not particular good at listening for this and describing this aspect.

Soundstage and imaging i think is quite similar to the haylou gt1 plus? I'm listening to Norman Greenbaum's Spirit in the sky and toto's africa, and the way the instruments comes in one by one sounds pretty similar in terms of their positing. I feel like any difference that I hear might just be down to the Z1 having more bass.
Not sure if that's helpful, but i'm liking it more than I thought I would. Ever since i got the Gt1 plus that has been my go to TWS most of the time, but now it'll probably be the Z1.
edit: oh and i did a battery test from full to the first low battery warning and it's not pretty. 2 hrs and 10 mins of use at around 45-50% volume (this is the same loudness that I use normally when listening music with any audio gear I have, the volume percentage looks low only because of how ridiculously loud the Z1 is able to get. lol)
