another thing to consider about comfort is the tightness of the headband vs headsize. usually you can adjust the tightness as well as the size via the sliding mechanism at both ends of the headphones. but some have a general "tightness," take this as an example:

i have a senn hd650. at the smallest setting, i can actually put it on my head snugly on top but the pressure on my head coming from the sides is very uncomfortable. i have to adjust 3 clicks at the sides so that the pressure is not that great. with my d5k, with the smallest setting, it's still not tight for my comfort. so i have to bend the headband towards each other a little bit to adjust it to my liking.
