Wire has been cut
My wire was cut, and I made it worse trying to fix it....with several failed attempts... was becoming despondent, but gave it one last try, and was successful. First, each little tiny wire has two internal wires, one green (ground) and one gold (hot). At first, the green one looked like some fiber or filler and I cut it, connected the gold wires and nothing happened. On further inspection, with magnifying loopes, I determined the green fiber was in fact green wire. There was also a lot of clear fiber, which is insulation? filler?... I don't know, but I cut it out, leaving only the wires. From the internet, I determined that the wires had a thin layer of plastic on them for insulation, which I burned off lightly with a lighter, connected the green together, soldered it, wrapped in electrical tape, then connected the gold together, soldered it, and taped again....and to my suprise it worked. I used twist ties, and epoxy to strenthen the area and was done, my headphones are working again.
