I LOVE the AD700 for gaming especially FPS, lots of soundstage, easy to drive, and super comfortable BUT no bass, very little. I have the original pink ones. I also have Q701 which was such a great neutral headset it was hard to upgrade from them. I knew I always wanted the HE400's but can never afford them, then I got the HE4XX FANTASTIC upgrade as I was wanting some bass with my soundstage. The AD700 is still the best with soundstage. The best all-rounder to me has to be the HE4XX, but you lose a bit of soundstage, but these cans are fantastic. Most comfortable AD700 easy, best details Q701. that's just me though
the HD58X I heard were also pretty amazing, I would go for those and save some money
