Ok folks, I recently won an Ebay auction I shouldn't have bid on. I was in a hurry, and not paying attention, and bid on a pair of DT770s that I later noticed were being sold "as-is". Well, one channel is dead. The obvious things like wiggling the cord don't help.
I have never owned a pair of Beyerdynamic headphones. Any suggestions as to anything I might try to salvage them?
