[PLUG-TALK] Headset repair

[Rich Shepard]

My Yamaha CM500 headset limits sound to the left ear. The company is
replacing it under warranty and does not want the old one returned.

Has anyone futzed with fixing a headset? I've no idea how to disassemble it
(so it can be properly reassembled) to trace wires looking for the problem
and repairing it. It would be great to have a backup headset here if someone
would be interested in the challenge of making it work.
