Thanks for the tip! I forgot to mention though, I'm mostly looking into closed cans because I'll be using these in a dorm and I don't want to bother my roommate, especially at night. Might even bring them to study in the library.
Although, I don't listen at obnoxious levels, so if there are open cans that don't leak obnoxiously, then I'd probably be interested. How much do the AD700s leak?
You'd best go with closed then. Even if you listen softly it will be noticeable in a place like a library. Its, probably enough to bother someone who is trying to fall asleep, but not something that would wake most people up.
You might want to look at the A700, closed version of the AD700. It supposed to have a nice soundstage for a cheap sealed 'phone, but I've never heard them myself.
