I love my Logitech G35. It was a MAJOR step up from my stereo headphones... Until very recently. When I noticed a few things with my headset. Do the Logitech G35's/G930's have real 7.1 audio? As in the number of channels/drivers needed to make it 7.1? Because there's this button on the side I slide up and down. And even if something is stereo it sorta. Spreads it out to mimic surround sound? I realize I probably have no idea what I'm talking about but basically what I'm trying to say is. I'm planning to purchase a new headset sooner or later this year, and I ABSOLUTELY LOVE this headset/the wireless version. But I am having doubts about the sound/inner workings of the headset.
