I've had my RP21's for over a year now. I bought them used in the For Sale section on this site. Recently, I was unable to get any sound of the right channel, I tried different cables (it's detachable) but that didn't help. Is there away I can fix this myself or should I move on and get a new pair of 'phones?

Probably the wiring inside the cups are frayed. You'll need to open them and see

That happened to me as well, the wires inside the 'phones are very thin so every little jerk on the wire might tear it, all you have to do is just solder it back to place.
