No, I am not concerned at all about in game voice.
The one and only thing I am interested in is finding out whether the 1820, using the headphone out, will give me accurate indications of:
left/ right
up/ down
front/ back
I am guessing that music mixed in stereo can fill any of these "directions"...so I was hoping that sounds made by other players in the "3D" space of a "map" would be accurately reflected in my headphone cans
My SB live! gives me great directional reference via the stereo headphone out...I wondered whether the 1820 would do the same.
