Headphones

Just out of curiosity, what sort of headphones are you all using for recording/listening? I've used Sony MDR-7506s for a while now. I really like the sound of them for recording, listening to music, and listening to concert DVDs when I'm in the need for VOLUME and don't want to get an eviction notice! I've heard some people that prefer an absolute flat response say that they are a bit on the bright side, but I still like them.
