RA200 Rugged Air Aviation Pilot Headset
I bought these for my Son and when my David and Clarks started messing up on me I started using them.  They work well so I bought a few more pairs. Most of my flights are within a couple hours so I can't speak to comfort on a true cross country flight but for all the local (1-2 hours) stuff I do they work just fine.  My son likes plugging his iPhone into them so that he can listen to music or hear his games when we fly.
