A lot of people Like Sennheiser's who game because they are very comfortable for prolonged wear. Personally I think Grado's will give you a fuller sound, but Sennheiser's HD series is better for more neutral sounds, but if you're into high energy techno or trance (like me) then you'd appreciate the Grado's a little more. But they become uncomfortable at lan parties because they don't have the nice all-round the ear padding for comfort that the Sennheiser's do -- but since I'm a diehard fan of Grado Labs, I just deal with the red ear factor the next day because you can do whatever you want without worrying about the consequences and you'll probably end up better off than when you started.
