Yesterday, I plugged in my M50 to my smartphone and played a few songs. Then I noticed some distortions. As I move the cables around, it makes weird static noises like some wires were loose. I then plugged it to my computer, same problem occurred. I tried shaking the headphones (heh) and it becomes normal again. And today, the right becomes unreasonably louder, bass is just too loud, and soundstaging is just so poor. Everything sounds like it comes from the center of the driver. And I'm sure my brother use it yesterday (since I found it at my living room today instead of inside the casing).

I've tested with many songs on my computers and also tried swapping channels. So I can confirm that the right driver is broken. What just happened? I accidentally dropped it once, but that was almost 2 months ago. I need advices please. Thank you in advance.
