How can I repair an enamel coated headphone wire? In other words, how can an enamel coated wire be reconnected; i.e. how is the enamel coating stripped off, and what can I use to recoat it so that it won't short?
Strip off the coating to expose bare metal where you would to slice (reconnect) new wires. Twist them or soldier them together. The wires will not short unless they come in contact with electricity-conducting materials, including human flesh. Hardware stores sells paint just for wires, but you don't have to go such extremes. Just put some tape it or cover it with any other non-conductive materials.
