I've been looking for a new set of headphones and want something easy to drive, good sound and very comfortable. I've narrowed it down to the Bose AE2 or AIAIAI Tracks.
 
I've tried the Bose AE2 today and think they sound pretty good. Unfortunately I can't try the AIAIAI Tracks and I'm hoping someone can tell me how the sound compares between the two?

Oh yeah, other suggestions are welcome too. I'm looking for something easy to drive and not large like a studio headphone.
 
I also tried the Klipsch One headphones and liked the sound, but maybe a little too much bass, although they weren't as comfortable as the Bose. The Bowers & Wilkins P5's are extremely nice but expensive, and not sure about the comfort.
