The AX 51 PRO is a mid-range gaming headset from Tritton. Unlike the entry-level AX 180, the 51 PRO processes 5.1-channel audio for a three-dimensional effect via 8 individual speakers. Designed primarily for PC gaming, it features a backlit inline audio controller allowing independent adjustment of each sound field. The microphone is rigid and detachable, allowing the AX 51 PRO to be used as high-end headphones for watching movies. Higher-end models add Dolby Digital support.
