LG Headset HBS style, earbud wires conductor failure

My LG headset has earbud wires that, due to use and flexing, the conductors within the insulation have broken on one side. I don't mind a little disassembly and soldering, but these wires are very flexible and very fine-gauge conductors. Anyone know where I can find a good source for these wires to try out a repair?
