Grado RS-2 Reference Series

Pros: Superb, almost perfect sound

Cons: Uncomfortable. Leak enough sound to bother others close by.

Summary: These have a marvelous natural sounding performance. I haven't heard a pair that's better. However, because the ear cups press down firmly on the pinna, they are only moderately comfortable when you slap them on, and acutely uncomfortable after 30 minutes of continuous wear. The outer ear becomes flushed, hot and a little painful from the pressure. These cans also leak enough sound to disturb anyone with fifteen feet from concentrating at their task. As great sounding as they are, if I'm shelling out half a grand, I'd look to more comfortable options such as the Sennheiser HD 650 or AKG K-701.
