About a month ago the right cup just died on my Sennheiser PC-350s so I sent them back on warranty. They came back a few days ago with a note saying they tested just fine and there is nothing wrong with them, but there is something wrong with them. (I think)
Whenever I use them on my PC the sound eventually fades out then the right side just completely dies, unplugging them and plugging them back in may or may not fix this. After the right side has died on them I can try them on other devices; ipod, laptop ect and that right side will remain dead. However, if I plug them into my old television they spring to live immediately every time. The only thing I can think of is that TV has a pretty strong headphone amp but I have no idea about this sort of stuff.
Are these things faulty or could something be wrong with my PC that keeps killing the right side channel?
