Sometimes when listening to music or gaming I can hear the left channel getting softer and softer until it fades out completely. Sometimes unplugging it and plugging it back in works, but this is at best a 50/50 fix.   I checked a few things.   Plugged it into my speakers and this happens. Plugged it directly into the back of my PC and this happens. Tried them at work the same way and it happens there as well. Doesn't happen to my other headphones, either at work...
