So, I just got some beats studio 2 wired given to me by a customer. She was hella cool and I fixed her service. She was super stoked. She said the left ear doesn't work. I got them home and found out both speakers work. The left speaker is very faint. The right speaker is rockin'. I've taken apart the left speaker to isolate the trouble. It's not the foam padding. I also cleaned the headphone jack before I took it apart. No avail. Has anyone else taken these apart?
