Hardware Pacers has posted a review on the Tritton AXPro

The Tritton AXPro is an amazing and complex set of precision gaming headphones. When purchasing the AXPro, a gamer is not only getting a set of headphones, but is getting an eight speaker Dolby Digital / Pro Logic entertainment system that fits on the head. This system produces True Dolby Digital 5.1 Surround Sound through the 8 individually controlled speakers. If that isn't enough, the system even comes with a Dolby Digital & Pro Logic Audio Controller. Amazing sound quality gives the user an experience that gives the feel of actually being immersed in the game. Two AC power packs to use a headset is somewhat cumbersome, but if a user has the available outlets, this system is a superb choice.
