I got a great thrift store deal ($10) on a good pair of Sennheiser PXC-250 noise-canceling headphones. The only issue is that the headphone jack was damaged internally and one of the channels would cut out every so often and require wiggling to get going again. I figured I could easily rewire the phones...basically just slap a new radioshack plug on the end and make the connection with electrical tape and a quick solder job. I also figured I could dump the noise-canceling "wand" that I never use...so basically I planned to cut out the noise-canceling wand, shorten the overall cable length and connect a new jack to the shortened cable. What I found when opening up the noise-canceling wand is that the cable for each ear piece has within it four wires. The cord that goes from the music source/jack to the wand has the standard three wires, but once in the wand each channel gets 4 wires each. As you can see in the pic (sorry for the crappy web cam quality), each channel's cable has two copper wires and a blue and a red wire. To be clear: out of the wand there is a cable to the left ear and a cable to the right ear, and each of those cables contains four wires. Upon cutting into the cable, I found an inner plastic sheath that contained the red, blue and one of the copper wires, and the other copper wire wrapped around the plastic sheath.
What I'd like to know is, how do I wire this thing back up to a standard jack - which wire goes where? Thanks for any help you can provide!
