My headphones are crap. One speaker works, but the other doesn't. wats more is theres only one wire that goes into the left speaker, and from there leads another wire to the right speaker. I don't understand why the right speaker isn't having problems when the left one is, and they're sharing the same line. There are also no breaks in the insulation and taken apart, all the wires/copper remain soldered, intact to the speaker. From time to time if I move my wire, sound returns, but if I move it to the same position after letting go, it won't work. So WTF is going on and how does me fix it?
