I disagree about not getting the HPX (or HPA2). They are considered the BEST gaming headset outside of the MMX300 (which is worth quadruple the price). They actually have a VERY good sound even for music. They do everything relatively well for gaming, including bass, clarity, and positioning. Even one of my audiophile friends has the HPX and prefers it over the AD700 and a crapload of other higher end headphones, which he tested with gaming.
I also disagree about bass not being important in gaming. Granted, it ISN'T important in competitive gaming, but for any other game that you're not fixated on your online rankings, bass adds to the immersion. A good headphone can sound as good as a home theater, when paired with virtual surround.
That's why I'd own two gaming headphones. One bass light for overall clarity and precision, and another for home theater like sound. Or choose something like the DT880 which is a good mixture of both.
The AD700 is a serious gaming headphone, but has absolutely no fun factor to them, outside of their outstanding soundstage and positioning. They are a dullfest when playing in a non-competitive setting, like a campaign or something.
