I bought a pair of Beyerdynamic DT 770 Pro 80o's and along with it a Fiio E11 amplifier. Everything was going smooth until about an hour ago when I was playing around with a kick in Ableton and turn the volume up too high. Now, if any even remotely low frequency plays in the RIGHT phone, there is just fast paced ticking. The left phone is perfectly fine but the right one seems to be broken. What did I do?? And why didn't the left phone break at the same time?
