so far at school i have seen the usual beats and ibuds, i have seen some "dynabass headphones" that sound like fart cannons. for the good, i have seen someone with a pair of m50s with the removable cable mod, because i modded it for him, and i have seen a person with v-moda crossfade lp. i have also seen some bowers and wilkins headphones, many pairs of random IEM's. also one of the chemistry teachers has a pair of sennheiser mid-fi over ear headphones, which he loves. i have also seen a few pairs of monoprice 8320's, but only because i sold them for $10, which i believe to be a fair price. and some sony on ear headphones
