So I got some really nice 5.1 headphones for Christmas (Turtle Beach Ear Force Charlie), but I think they may have already stopped working. The problem is, one of the speakers, the front right one to be exact, is extremely quiet. When I go to my audio manager and shift the balance all the way to the right and turn the volume up, the sound comes in, but there's a lot of static. Is this a problem with the headphones themselves, or could it just be a faulty cable?
