I think he's wearing some variant of the Sennheiser HD25, although I can't tell much more than that. Can somebody else identify it further?
At my high school, there's a ton of Beats (Mostly Solos, Studios, and a few of the other models), and other various low-end gear, as expected. Today, however, I saw a guy who I believe was taking photos for our school magazine using the Sennheiser HD201 or some other low-end Sennheiser model during the photo shoot. I kept my distance, so I'm not 100% sure.
There's also this dude in my psychology class who occasionally has the Bowers and Wilkins P5 out since my teacher permits music during classwork. When I inquired about his phones, he not only proclaimed himself an audiophile, but recommended me his set, telling me the P5s were worth their price. I neglected to ask him if he knew head-fi, though. =(
