techPowerUp posted a review on the Razer Barracuda HP-1

The Razer Barracuda HP-1 is a unique headset which offers true surround sound. A number of small speakers in the headphone are placed at different positions and are driven by a small amplifier included with the headphones. Now you can enjoy positional sound effects while using a headset. In our testing we found out that this makes quite a difference in games like Counter-Strike or Battlefield, where you can locate enemies based on the sounds they make.
