Ø9.6mm Dynamic Driver
Bigger drivers don't translate to a better sound, as my experience with KZ ED4 has proven. You would expect a massive bass from these drivers, but you only get a standard one. The vocals and highs are so loud and harsh that it makes you want to take these earphones off and throw them away.
There's another issue which seem to be plaguing many KZ earphones: they use extremely weak glue. That plastic nozzle part broke off as soon as I tried to take the ear tip off and I had to glue it back myself with a more decent glue.
NOTE: These earphones' sound signature is suspiciously similar to KZ GR's sound signature. After comparing them, I can confidently state that they sound identical to me.

Comfort & Fit
I got a good seal with the pre-applied M-size tips. No problems at all. Still, the generic tips aren't the best at keeping the earphones inside.
Lows / Bass
The bass is pretty deep and precise, and even has some sub-bass, but it struggles with it, almost as if it's about to crack.
Mids / Vocals
Very audible sibilance in the vocals make the whole listening experience fatiguing.
Highs / Treble
Excessively harsh highs. They are so loud that listening to these earphones just for a few minutes can induce a headache.
