I'm looking for comfort and portability.
I also realize the DT770s require an amp, but not positive on which one? E11?

Hi Tristen,
 
The E11 will suffice for most situations.  I've said before that the DT770 actually needs a good amount of juice to really shine (even 80 ohm version), but that's only when you are really wanting to extract every last bit from those cans.  DT770's are not quite so expensive now and I feel that they are a good contender against the venerable M50's.  Suffice to say, I am quite a DT770 guy even though I now prefer the 880's and my DT 1350's.
