Is it possible to repair wiring in right cup on HD668B? I believe the wiring is messed up in the right cup of my headphones (or atleast someone on these forums said so.) Is it possible to repair and if so how? I bought these on amazon. Is there a warranty? I am looking on the box and seeing nothing about returns or waranty. I have had them just over 2 months now. If nothing else which is better for battlefield 4 gaming, the AD700x or hd 558s? Thanks in advanced.
