Hi ! Thanks for this review
I also read your review about the CCA C10 that I own, I was wondering if it was worth changing but I don't think so anymore.
I'll wait for the next KZ with 16 drivers to see if I change or not (I also have the AS10 and ZS7 but C10 are my favorite).

This is reasonable, because the C16 is not a big upgrade to the C10. You get more details, resolution and separation, but they're not 3 times as good, which justifies the price difference.
Besides, I also see the C10 slightly in front of the ZS7 and also in front of the AS10, which is a bit too dark/warm for me. There the BA10 is more refreshing.

But I assume that the AS16 does not differ much from the C16. I could imagine that the V-signature will be more pronounced at KZ, which will lead to more bass (like the AS10) and a small treble boost. I hope, however, that this won't make them too sharp again.

As10 is good, but yes a little too warm for me too, and also has a little soundstage compare to the C10. ZS7 is overall good but too bassy on some tracks, that's why I prefer the C10.

Can you help me to understand the proper polarity with the same combo (C16+**** 16 core)? From your photos I see that the blue dot on the cable facing up or "outside" part of the earpiece. I found anther review of the cable with completely opposite direction. I understand that with the wrong polarity the sound should be off, but I can't really feel the difference (probably because I've just received mine). Thanks for the review!
