First of all these be very very high quality build headphone , thick plush leather , strong dense aluminum . they be over the ear head phone , and be very snug and comfortable . I have hear of people say they hurt , that be a total lie unless you have huge ear but my ear fit perfectly inside the cup . I would buy these again and again . they be the best dre headphone out there . they be $ -lrb- ... -rrb- with shipping , but I guess I have they now , lol . they be very expensive to what I really think they should be sell for but they be worth it if the Studios be $ -lrb- ... -rrb- . these be total show stopper and have a very clean sound . I have use but not purchase one over $ 1000 but they be for more of a recording purpose type of headphone . these be truly a great product but think they will require alot of juice to run off of a ipod . again these fit well on normal size ear .
