I got sennheiser pc160 and i'm happy with them for gaming. (certainly better than hd650)
Maybe they aren't as good as AD700 etc but i use ventrilo everyday so i really needed the mic, and the mic on the phones has really good quality.

sometime bigger soundstage makes you got the wrong judgement of other players position .

if you have a loud computer, the open headphones will be rubbish for gaming - closed at least isolate the fans and your friends

depends on the kind of gamer you are

closed and open phones exist and you should make the decision that's best for you

when i played CS open was by far better because playing at competitions meant i could hear strats from our caller without the delay of in-game voice comm

for solo games where this isn't a problem closed might be better, or if you have a noisy pc/surroundings the isolation of a closed phone might be more suitable

on the other hand i find that generally, but not always, open phones have better sound staging and positional audio than closed do

In regards to the A700 and AD700 I lean toward open for competitive multi-player. I might prefer the closed for everything else. Closed will make a grenade deafen you like it should. Open will let you hear what going on when you should be deaf.

Aside from the actually gaming I have chosen to use the open because I want to hear what is going on around me when I play. The closed will shut you off from the outside world. Of course that's what a lot of people like. I also feel the open are more comfortable. They let your ears breath where as the closed will get hot after a while.

I don't listen to many movies on my headphones but I would think the A700 would be a lot better than the AD700. However, I wouldn't enjoy enjoy wearing A700 for 2 hours strait especially in the summer.

So anyway I would say A700 is better choice unless you have a reason to use open.
