I have been testing and using the x7 for a week or so now. Got ti in early Dec but just got the time to try it out really. I have played with the settings a lot and I am having a hard time with it, in BF4 specifically. My onboard sound on my Asus Rampage IV Black is giving me better positional sound with my AKG 712 Pro's.
The game is set to Hi-Fi. The setting in the x7 is headphones, I tried the direct mode. I tried scout mode and SBX mode and turning surround up to 69% ;) I can barely hear foot steps even from my own team. But when I plug into the onboard sound I hear foot steps everywhere, directional foot steps etc. It is not near as good with the x7.
Suggestions and what settings are you guys using?
