My dog ran into my headphone wire while I had my headphones hooked up to the TV. Upon doing this, the pin on the end of the plug snapped off as it unplugged. After fishing out the pin from the headphone jack with tweezers, I tried to put it back together, but only sound comes out of the right ear. Is there any way I would be able to fix this without having to send it in?

If it helps, it's a pair of ATH-M50s I've had for a few months.

Thanks in advance!
