I am looking for headphones which have great soundstage for positional audio in FPS games. I would like to be able to locate opponents footsteps, distance of gunfire, etc. But I am a bit of a bass head so I would still like to have some decent bass. It will be nice for explosion to have weight and impact. In addition, I plan to get virtual surround sound using both Yamaha Silent Cinema on my RX-V673 AV receiver and Dolby Atmos App on Windows 10 and my on board motherboard audio. I understand that I would likely need open back headphones. I am looking at: Sennheiser HD 579: some reviews say its soundstage is inferior to other Sennheiser headphones. ATH-AD700X: I hear it has no bass response. I would appreciate any other recommendations.
