Not only can you hear sounds in front, left, right, and behind you. You hear sounds ABOVE and BELOW you as well. You have to listen to it using headphones though or the effect is lost. Its a freaky sounding clip even though there is nothing about the sounds themselves.
It uses a recording technique called HRTF

The head-related transfer function HRTF, also called the anatomical transfer function ATF, describes how a given sound wave input (parameterized as frequency and source location) is filtered by the diffraction and reflection properties of the head, pinna, and torso, before the sound reaches the transduction machinery of the eardrum and inner ear (see auditory system). Biologically, the source-location-specific prefiltering effects of these external structures aid in the neural determination of source location, particularly the determination of source elevation.
