Got a replacement cable for the HD800. Left earcup, no sound. Can't remove the cable for the right earcup no matter how hard I try. How the hell does somebody screw up a cable THIS badly?! Demanding a refund and a new HD800 is going to be hard to do successfully. It's a freakin' cable, I don't see how I could screw up the installation - Plus, I've installed the stock cable multiple times without problems.
