Not gonna try to persuade either way but I have the standard Clarity Aloft and, though expensive, is extremely comfortable for multiple leg days. I can't do the over-the-ear thing anymore. I know Bose, Lightspeed, etc make light headsets with little clamping but more than 4 legs in a day and my ears start getting irritated with the foam or whatever around the ear.

QC15s would be nice for commuting, though!
