While other headphones offer simulated 5.1 surround sound through various tricks and technology, Razer includes eight discrete drivers, four found in each cup, that provide a true surround sound experience. The headset also supports a detachable noise canceling microphone for communicating with team mates, or more generic uses such as Skype.
Each of the cups contains four drivers; one bass/subwoofer, and three mid-high frequency drivers. The three mid-high drivers are used for the positional aspects with one acting as the front, mid, and rear respectively. Connecting the headphones is done through the Razer-specific HD-DAI (High Definition Dedicated Audio Interface). Most sound cards do not actually support this specific port, so Razer includes an adapter that is universally compatible. A module that clips onto your shirt acts as both the amplifier that drives the speakers, and volume control. Each of the channels can have their volume individually adjusted along with a master volume.
The 5.1 audio is fed into the headset through a 3.5mm jack. If you want to get audio from a device like an Xbox 360 or dedicated DVD player a Y-adapter can be used though that removes the surround sound capabilities. Surround sound is supported with a more complicated setup that involves adapting the output from a dedicated receiver for the 3.5mm jacks.
