I find that most games from the Source Engine (Team Fortress 2, Counterstrike) benefits from closed back headphones. Which is great; because competitive games pair well with sound isolation. There are games from the Frostbite Engine (Battlefield/Crysis) that benefit from the extra audio hardware.
Then there are semi-competitive games like Call of Duty (ugh) that actually do well with the Q701's because they have fancy filters (like muffling sounds) to give the listener the perception sounds are coming from behind.
To each their own hardware and game I suppose. I'm sure someone has a different opinion than I do
