Has anyone tried these before? For some odd reason, the right earphone sometimes doesn't play any sound, and I have to bend the wire in a certain way in order for it to play anything. The left one works fine, but the right one's just dead. I have to either hold the wire, or tie it with something, which most of the time doesn't even stay together the way that'll get it to work (I have constantly keep rearranging how it's tied). Would anyone know how this can be fixed?
