hey shoryuken,
you could try checking www.ifixit.com and see if they have a repair manual for your model. if not, maybe try contacting the manufacturer directly and request a wiring schematic - but I'd make sure you're at least moderately comfortable with wiring / digital circuitry before you go digging. you might get lucky and find it's a quick fix.
and yeah if worst comes to worst, you could get a new pair. creative has the tactic sigma (multi platform wired) and the
tactic 3d omega headset (multi platform wireless), and I consider both fairly comfy, plus the build quality on the omega is respectable. i'm 6'2 and have dropped them on tiled floors multiple times and they still play fine. you should have no problem chucking them into the couch haha
i hope you're able to fix your headset man. best of luck
