I currently have a Sennheiser Game Zero headset, but when using sonic radar 3 ingame it doesn't seem accurate when trying to locate foosteps. So my question is do I need a 7.1 headset in order to fully utilize Sonic Radar 3 to be able to locate all sounds as opposed to my normal stereo headset that I have currently. I'm thinking about buying the Logitech G633 as it is a 7.1 headset. Please let me know. Thank you.
