Please, listen to the negative reviews! I've had these for 2 months and this has happened to both sides. I didn't sit on them, or even fall asleep wearing them, this is purely from taking them off and putting them on. And there's no warranty so I'm SOL. I understand what Drop is doing here, and how they keep prices low, but for their reputation they need to do a better job at product selection. These headphones shouldn't be for sale on this site. They are pieces of garbage. The sad thing is that I loved them before they broke. They sound great. The other sad thing is that before now I trusted this site completely. I don't anymore. Oh well.
