The Audio-Technica ATH-AD700 deliver huge sound at a very reasonably price. Not only do they have a soundstage that makes more expensive units jealous, but they also have two innovative "air wings" that gently support the phones on your head and provide hours of comfortable listening. The rigid magnesium frame and aluminum honeycomb casting make for lightweight durability, and the massive 53mm drivers bring the bass. Listen to what Good Gear Guide had to say about these cans:

To put it simply, we haven't heard anything as immersive as the AD700. The power and positioning of the individual instruments is mind boggling, surpassing pretty much everything we have seen in this price range (including the A900). Soundstage is paramount to a proper listening experience. If you can close your eyes and visualise the sound in the appropriate place it goes a long way towards creating that spine tingling feeling we strive for when listening to our favourite tunes. The massive soundstage is also perfect for positional audio. We'd venture that in terms of un-amplified headphones, it doesn't get much better for games than the AD700s.
