I've got two pairs of Koss PortaPros, both of which have broken at the plug. Unfortunately, I went and tried to fix them myself instead of using the warranty I wasn't aware of. I can't solder something that lasts more than a week or two.
How on earth do I get the paint isolation cleanly off of the wires (of all the things to use for isolation)? I've been trying to burn it off using a lighter with less-than-satisfactory results. I also have shaky hands which make getting a reliable solder at the plug a pain. Would it be easier to get a nice big plug with well-spaced solder terminals or get some cable with a plug already attached?
I'm mad at myself for missing the warranty info...
Any help greatly appreciated.
