This is unconfirmed if there is actually v2 or there was just QC issues which is quite common to KZ production.
Atm, all we know is that there are just black and colorful version which should sound same and have same components.
Nevertheless, too much hype around ZST and little objectivity imo. Few respected reviewers already gave their impressions and they don`t seem to be "very special" and still have some "faults". Will they fit for person subjective taste is another story.
I agree with this. It's not 100% certain if they changed anything, or if the first batch was off, or if the early reviewers simply didn't like the sound signature. If only Horton was still around...
Since B9Scrambler accurately described his black ZST the way I think about my colorful ZST, I personally assume that the current black and colorful versions should sound the same.
You don't even have them and you're giving negative reviews about them? That doesn't seem right. I'll take the countless numbers of excellent reports on here as evidence that the ZST's are excellent performers and it's not just me who says so.
I don't think CoiL was speaking bad about the ZST, and I also personally feel that the ZST is slightly overhyped right now. The faults that were mentioned aren't coming from CoiL, but from what he read in other reviews in this thread. It's also very true that whether or not the ZST is good depends on personal taste.
In saying that, a "fault" for someone might be a strength for another person. B9Scrambler listed "thin mid and upper registers" as a con in his mini-review. I personally hate high-mids (a lot of J-pop songs sound too piercing to me if the high-mids are boosted), so this actually becomes an advantage for me. If the ZST had some more low-mids and slightly less treble, it would be the perfect IEM for me, but a fellow guitarist tried them on yesterday and said that he preferred less low mids and more high mids (he owns a Shure SE425), so the electric guitars would be more present in the mix.
There isn't really any wrong or right, as sound signature is all preference-based. Because of this, if someone says IEM A >>> IEM B, it should always be taken with a grain of salt, as it does not apply to everyone. I genuinely prefer the ZST over the 12-BA UM Mason, but I can't just go around and say ZST > UM Mason.
