Very informative thread. Hope you don't mind me asking this a little off topic. I have a pair of Studio 2.0 which stopped working a few days after a bought them, I was already overseas and warranty has been a pain so not going down that route. Basically the ANC is not working, although I do hear the hissing sound coming out of the right ear.
I've opened them up fully several times but cant figure out whats wrong after checking all the connections carefully. I'm wondering if it could be a firmware issue? Have tried resetting them numerous times. I wonder if beats warranty tech's have usb software that would let me re flash the firmware on them or something =_=;
I should also mention that initially they would not turn on so that's why I opened them up, after pressing on all the wire connections I was able to get them to power on again, however after that noticed the ANC not working :/
