I do not have my headphones yet, but actually had this very question and want to clarify. When plugged into my PC via usb, the headphones appear as different audio devices depending on which mode is selected? When I turn off 3d on the headphones does that essentially disconnect whatever device was there before and instead show a new device? Is there actually a way to change between 7.1 and 2 channel directly on the headphones? I guess the reason I am asking is because it sounds like from what you said it effectively disconnects the previous audio device when switching modes, so I would assume that for gaming I am going to have to ensure I have the correct mode selected on the headphones, then change the default device in windows. Or does the device essentially take over as default whenever its plugged in/changed?
I just want to make sure that I am getting ture 7.1 surround sound in my games, and I know a lot of them are very picky and set directly based on what the default audio device in windows is.
They register as three separate audio devices, yes. Each volume level is managed separately by Windows, so make sure to switch to each mode by holding down the microphone scroll wheel and reduce the volume on each input so you don't blow your ears out. You can set each one as the Default device and it will automatically select it when you switch between them, since one 'disconnects' before the other appears.
