The CAGE should ideally be connected to a PC via USB. The driver can be used via USB and thus also the 5.1/7.1 sound.
However, the CAGE can also be used as a headset on a game console or smartphone/tablet via jack plug. Here, the output is exclusively in stereo. The virtual surround sound can therefore not be used. The CAGE is also recognized via USB on some game consoles or can be connected directly to the controller via a jack. The output is also in stereo here.
