I still have mine (v. 1). I called support once about it. It can get into a mode where it needs to be rebooted. Overall, they work fine. Be sure to download the app and install the latest firmware update. Also, using the audio cable and charging cable at the same time results in annoying digital noise in the headphones. It may be a ground loop issue that can be broken by charging and listening with different relative ground sources (gnd of USB must be different than the audio gnd).
