Welp it's time to break my headphones and maybe make them even better; here goes!

@mawr I don't have appropriately sized spare wire, so I'm using the wire from the cable. It's insulated with super thin epoxy or something, so I have to burn that off the tips, first.
@mawr next is the wiring of the headphone jack! Wiring up for a test first, then solder, then heat shrink tubing to seal it up all nice. ^^
@mawr No heatshrink on the individual wires? Insulation is good!
