Isn't that a Logitech model?
Sennheiser HD558 (especially with the simple foam ring mod) beats it handily in every way, except it doesn't come with an integrated mic (which isn't an issue because a separate mic is like $3-$4). I also loved the soundstage and competitive nature of the AD700... unfortunately gaming headsets are more marketing gimmick than substance.
The G930 is also wireless. Sometimes convenience outweighs performance. I know I still wear mine from time to time, despite having options that are far, far, better. The sound quality isn't great, but it's far from awful.
