Dog chewed up my wires on headphones (same one who used to eat my homrwork). One ear still worked but when I strip wires and put together it does not repair it. I even cut the working ear but could not reattach and make it work. Wires are very fine and not certain but looks like one set of conductors on one side and two on other. Seems like must have two conductors to each ear. Some strands are very fine copper and other strand looks more like a fine non-conductor fider. How can I reconnect?
