With my little experience with the M80s other than at a friend's house, I can still ensure you that it will not even be close to as comfortable as the AD700s. If you enjoyed the AD700's airy sound, you most likely won't enjoy the M80 sound. At least that is my guess, because they are completely different signatures. M80 is closed, less soundstage, more bass and lower end emphasis and less high end sparkle.
