Once I learned how to work the function button, everything was wonderful from there on

All functions are on one invisible button over the left earpiece, and is rather unusable

In wired mode, the center button disables noise cancelation and fades out the music

(no obtrusive buttons etc)

Sound!After the initial pair was returned due to a defective volume button the performance has been flawless.

The beats button feels cheap and seems easy to break, the bluetooth died on day 3 while I was using the headphones and now the bluetooth doesn't even turn on or indicate that it is working
