After reading a few threads about modding HD650's by taking out the foam that covers the driver housing, I decided to try it myself. I can't believe I didn't do this earlier... it really does make a difference. The highs are so much clearer now, it's amazing to realize that a piece of foam alters sound so much. I'm a Believer now!! Amen! 






Shouldn't be too hard I guess. Bahhh.
