Sound OK, processing Good

Sound:
Test to Macbook'13 and iPhone 5s, each without equalizer with 320kbit MP3 quality.
The sound of the V8's nice bassy, ​​but the heights are somewhat swallowed.
Same result in rock, hip hop, electro tracks.
Even with volume changes the quality remains the same.

For comparison, I had the V10, which have better treble downs vote and thereby sound clearer.

Processing:
Makes a quite reliable impression. Cable can be like Headband exchange. Where the headband is probably difficult to destroy, because it can easily turn in all directions. The earpieces fit securely on the belt.

Cable keys:
Have works fine with the iPhone. Acquit also worked.
