[M] Mad Catz TRITTON AX 720 High Performance Audio System Review
 

The TRITTON AX 720 High Performance Audio System from Mad Catz is a great addition for people that own consoles and prefer listening to headphones but also PC; the system comes with an AMP/decoder box that features Dolby Digital 5.1 Dolby Headphone Technology, delivering surround sound to our ears even if the headphones are stereo.
