The DPX21 combines two of Turtle Beach's hottest products into one deluxe combo package. We took our battle-tested PX21 headset, designed for PS3, XBOX 360 and PC/Mac gaming, and partnered it with the Ear Force DSS to transform the PX21 into a full Dolby digital surround sound headset. The PX21/DSS combo pushes your PS3 and XBOX 360 gaming experience to a new level with the thrilling realism of Dolby 7.1 surround sound and crystal-clear communication over PlayStation Network or XBOX LIVE and saves you a bundle over the cost of buying the PX21 and DSS separately. The DPX21 gives you a competitive advantage by bringing out sound cues in the game that are difficult to hear with speakers such as the footsteps of an enemy sneaking up on you or the loading of a weapon at a distance. By combining online chat while immersing yourself in DSS-powered Dolby 7.1 channel surround sound, you can efficiently communicate with online players without being distracted from the game. With its exceptional audio quality, online communication and comfortable ergonomic design, the DPX21 can help you become a better player while making it a lot more fun to play your favourite video games!
