So I’ve spent a few days with the ZS10 Pro, and KZ did a really good job with these. I like it a lot.
These have almost an identical signature to the ZS7. In fact, my ZS10 Pro crossover circuit boards actually say “ZS7” on them! Also, my FR measurements are identical between the 2, with 1 exception: treble.
The ZS7 had a very safe and tame treble, which I believe KZ did because of the ZS6 backlash. However, the ZS7 are a bit too dialed down and distant for me. As much as I love the ZS7, I always wished it had some more treble energy. Well, the ZS10 Pro is just that.
The bass is very deep and punchy. Soundstage is good. I am going to see if it can opened up even further with modding, so stay tuned on that.
There’s a midrange peak at 2k and again at 4k, which give vocals a nice warmth and forwardness. Mids are more forward, which makes vocals come alive. Lead singers sound like they’re properly in front of the band, not the other way around.
Now, I know some people dislike those upper mid/lower treble bumps, but that’s a matter of personal preference. I for one prefer those upper mid/lower treble bumps.
So now into treble. There’s good clarity and air. Plenty of treble energy, but not sharp or aggressive. It’s just the perfect amount IMO.
Bang up job KZ!
So bottom line is if you totally hate the ZS7, then you won’t like the ZS10 Pro. It’s basically the same, plus extra treble. However, if you like the ZS7, but wished it had more treble, then you’ll definitely like these.
If you don’t own either, then I would go with how sensitive you are to treble. If you are ultra sensitive, then go with the ZS7. If you like treble and clarity, go with the ZS10 Pro.
You really can’t go wrong with either, unless you hate phones with upper mid/lower treble emphasis.
I liked the ZS10 Pro so much I bought a 2nd pair. I’ve been enjoying them more than the CCA C16, which says a lot. I’m still tip rolling and playing with the C16, so I reserve the right to change that opinion. But right now the ZS10 Pro has shot to the top of my favorite KZ IEM list.
Full disclosure, I am using both ZS7 and ZS10 Pro with Auvio tips, upgraded cables, and amp. I also relocated the ZS10 Pro crossover circuit board to the ‘side pocket’ of the shell, exactly like I did with the ZSN.
Anyways, YMMV.
