Unfortunately, it's really not very cost effective to repair these. It would probably end up costing as much as just replacing it.
Are you handy with a soldering iron? I could probably walk you through it.
Otherwise, I would shoot EtyRick an email explaining your situation. He might be able to help.
I can solder. Once things get tiny, I'm not great. I was thinking of doing this, however I don't know how I would make it look normal/cover it up, after the repair.
Shrink tube around the part of the resistors and a new male 3.5 mm plug should do the trick to make it visually kind of normal again after you've replaced/fixed the cable.
By the way, a "helping hands" soldering aid might be immensely helpful during the procedure.
