Actually, i was trying to fix my pc's sound that actually worked if i moved the headphone plug on the pc, i did it with my headphones plugged in seeing if it worked, i was so pissed i tried it too hard and the thing broke.

Is it just standard 3,5mm Jack stereo? If yes, go to electronic shop and buy new plug. Cut the cable and attach it to the plug. It's not so hard to do,
Get a 3,5mm stereo jack. Cut the broken one off, and deisolate it. The problem is that the cable has a thin film on it which bewares it for short circuits. You have to melt it away, a shitty job because you can't see if its off. Then you have to braze it on your new jack. Getting a new one is much easier.
