Very good sound, what I was looking for, the bass is the best I 've heard in headphones, I don't know if there's any better for the price but so far these are the best KZ I 've ever bought.

This was my product that came with the shortest delivery, only 14 days for my region es/Brazil. As usual the KZ always surprising with your headphones! About this model Zax, it really is a smaller When refers to the ear, is very comfortable, and smaller until the line ZST, but in depth when entering canal, it is a little bigger. On the issue of bass, medium, medium high and high in a flat position equalizer, it makes more evidence frequencies and high, ie with this he lets you listen to music very clearly. But like all keyboard like a bass more, will still continue to use my KZ AS10 as monitor for touch, because the bass are much more evident without the need to equalize. Anyway the model Zax is top notch, recommend the seller!

The headset reached my side in 20 days. I ordered it on September 29. Since China is a vacation from October 1-8, I think it's a little late. The headset has a quality structure. It gives much more detailed sound than the ZS 06 model. I experienced the headset with Hidizs AP80. The first impression of highs bright, mid neutral and bass balanced. I listened to flac and dsd format in Pop and electronic music. Stage and dissolution price is successful as performance. The device responds to eq adjustments in a very good way according to your audio taste. He satisfied me in general. A minus aspect is a grated structure on the outside, which misses a small amount of sound out of high noise. Kz's reference cable is the gold plated cable, and I will listen with that cable. I'll rewrite when I get to the cable and listen. I recommend those who want to.

Super sound!
