Put the beyerdynamic 770 and 880 on your shortlist too. They are simply superb.
I have them both! The 770s are very powerful in the lows and somewhat similar in sound to the Audio Technica ATM-50s, but with a broad dip in the midrange. If you're tracking with any of these two (singing), make sure to mute the bass track, since the powerful bass will throw the singer's pitch off (happens every session with every singer, in my experience).
I also have the AT-40FS which, with its much more polite bass, is better for singing. The sound is far less impressive, though...
The 880s are smooth and flattish, yet exciting to listen to. The smooth top end and comfortable fit makes it a breeze working with these for hours. Leaky, so no good for tracking with condenser mics. What I've noticed however is that the smooth top end, combined with the fact that Temporary Threshold Syndrom sets in pretty fast with headphones, makes me mixes far too bright, unless I'm careful!
