I've always had a problem finding headphones that fit comfortably, didn't leave my ears all hot, red, and sweaty, and that sounded decent.
I bought a pair of these the last time they were on Woot and they are perfect for me. I'm a bigger guy (6'4", size 7 3/4 hat) with proportionate ears that don't stick out. The memory foam on these (on the ear cups and the band) makes them super comfortable to wear, both on the ears and on the head. I haven't battle-tested them on a plane yet -- the ultimate proving ground -- but I imagine they would do fine, and would feel more comfortable for a long trip than other brands, or those damned ear buds.
No complaints from my coworker who shares my office, but then I also don't blast my music too awful loud.
I listen to primarily DnB, with the occasional tasteful dubstep, and a wide range of other stuff mixed in, and while they aren't the bassiest (it's a perfectly cromulent word), they are decent, and for $50, you can't go wrong.
I bought the black ones with the green cord, and I love 'em.
Pro tip: You can adjust the size by sliding the ear-cups up and down on the headband. I did not know this at first, and have since adjusted them to the perfect level.
