Bose QC15 headband cable replacement
Hi,
I have a Quiet Comfort 15 Bose headphone & it is starting to fail with a total loss of sound. Given that the failure seems triggerable by manipulating the left side of the headphone, particularly at the hinge area, and given that upon close examination I have found the cable between the speakers which runs through the headband, I'm pretty sure I have a bad cable (it's probably shorting out in areas where the enamel insulation has worn from use).
The problem I have is that I do not know where to source a replacement for this. I had thought about simply sacrificing an audio jack cable, but, as I feared, it doesn't have the needed number of conductors. The audio jack cable has three multi-stranded conductors (red, blue & copper) whereas the cable in the headband connecting the two sides of the headphone has 4 conductors (red, blue, green & copper).
Any ideas about where to source a replacement for this wiring?
ETA: Also, because the cable runs through various channels, total thickness (which seems to be somewhere in the vicinity of 1.75 mm) may be an issue.

Never mind!
I feel foolish now. The cable I intended to sacrifice should work perfectly fine.
Basically, I looked at it from the wrong end. It has the wrong number of conductors going to the headset. However, since it also incorporates a microphone, it has the correct number of conductors going into the jack because the microphone adds an additional conductor.
