I didn't do **** to them. I tried each ear piece to see which one fit best. They never stopped working when I did that, and I never pulled on the wire EVER. Once I found the best one, I set the phones down to go do something else. Before I went to sleep last night I though about listening to some music on them. When I put them on the left earphone wouldn't work. This is such ********. It's pretty much the exact same thing that happened to the Seinnheiser CX300's that I had. I'm getting really ****ing pissed with these headphones not working. I haven't even had them for 1 day before the broke. At least with the Seinnheiser I had them for almost a month.
