They're alright. I'd say they're slightly better than the earbuds that usually ship with mp3 players, but certainly nothing to 'write home about'. For people with small ears (like me

), they're very uncomfortable, and after wearing them for a while my ears start to hurt. This was the same for me with the default 1st Gen ipod earbuds.
edit: those v-moda headphones look awesome! i might just order me some of those, as i've been looking for some sweet in-ear headphones for ~$100.
