They're not binaural. They use the normal method of modifying phase and volume based on the direction of the sound. Binaural stereo uses spatially varying impulse responses for the sound channels, which creates a full and realistic 3D environment, including front and rear directions. There's also a better sense of how close the sounds are. But in a sense, it just feels you are in there.
