Sounds like you blew out the sub-woofer in the headphones. You could replace them, or if you've only had them for a year (or less) you can use the warranty included and have them fix it. All you have to do is call them up and ship the headphones to them.

you may have blown a speaker. check the wires behind the speaker to see if there is a short(two or more bare wires that touch)

Same thing with me, got scared and thought they were broken, but all mine needed were battery replacements in the subwoofer part :) hope it works!!!

See my tip on replacing dodgy/cables and plugs on headphones.

i had that , it gets worse. the poor design of the amp location means the wires fray inside the portals of the amp case. eventualy they will al sever and you will loose sound altogether. i dont know what kind of warrenty your under but i stripped the wires and solderd them back together and to solve the problem of them fraying again, i duct taped the amp to the headphones.

I've had this problem too multiple times. Usually when it happens, the battery dies soon after, and once I replace the battery, the buzzing goes away. If you are having the same problem as me, try putting a fresh battery in :)

yea i have the exactly same problem exept on my left??? did u find a way to fix them? i open'd them up and all the four wires were welded to the appropriate port. i think its in the wiring.... :( this is just very sad stuff with such beautiful head phones
