I've tried many different studio headphones and I have yet to find one that scores well in all the important categories, which to me are sound quality, comfort and durability.
The Audio Tecnica M40 and M-50's sound decent and are fairly comfortable, but the earcup material breaks down pretty fast. The industry standard Sony MDR-7506 headphones have the same issue, but sound really good.
AKG K240's (which many people swear by) sound dull and thuddy and are uncomfortable, but they are built very well.
So far, the best overall headphones I've had are my current Beyerdynanic DT-770 Pro's. They sound really good and accurate, very durable and comfortable and the earcups have a soft, velvet type of surface that I like. However, they are expensive. Not as expensive as those silly Beats units, but worth the money.
BTW, I assure you that those Beats units are made by one of the main manufacturers of headphones and just put Dr. Dre's name on it.
