Headphone Match?

What would be an appropriate closed ear headphone match for a earmax pro tube headphone amp in thu sub $200 dollar range?
closed ear? I am not sure if you mean inside the ear or the usual on the ear types, but Grado phones have impressed me lately. Buy whatever model that your budget will allow and I don't think you can go wrong with them. Their phones may be less controversial than their cartridges, as they do not pick up hum!
I should clarify. On the ear type, not the phones you can hear from the outside once they are on. No noise phones.
