Hi, I have a Sennheiser PX-100 with a broken  3.5mm jack. Therefore I decided rather then buying a new pair of headphones, it would be cheaper to solder it to a new 3.5mm jack.
 
To cut the story short, after I stripped the black wire, I realised that instead of the usual 3, there are 4 wires inside. A Green, Red, Blue and Gold. Can somebody tell me which is ground/left channel/right channel? Thanks!

If you dissect the broken plug you should be able to determine where the wires went.
