I'm looking for a pair of headphones that will suit all my needs.

They need to have strong bass for gaming.
They have to be comftorable!! and able to breathe so my ears don't sweat.
They also have to be able to "keep the sound in" for quite places, such as the library, or an airplane.
They have to be under $80.
They don't need an amp to sound good, something my rio volt can handle.
They need to be durable.

I have a Sound Blaster Audigy, and play games like Soldier of Fortune 2. The type of music I listen to is mostly rock: System of a Down, Korn, Red Hot Chili Peppers, Rancid, Godsmack, Disturbed, Korn, etc.

Is there such a pair of headphones?
I've heard the Sennheiser HD 497 ones are good, but do they meet all my qualifications.
Is it even possible to have a pair of headphones that breathe, yet keep the sound in?

I think that's it
