5.1-channel surround sound from any headphones is possible when input channels are processed using user-selectable head-related models. Natural sound is only achieved when the sound-scape is updated in real-time using information about the orientation of the listener's head. HeaDSPeaker does all this with the help of a patented head tracking technology.

The illusion of a home theatre in the headphones is further enhanced by generating a configurable amount of room reflections.
