5.1 dolby surround sound. Dual bluetooth capability for game and phone syncing. Wireless with rechargable internal battery. Optimized call of duty presets and voice programing. Top of the line of the Limited Edition Turtle Beach headsets to date. New in box has been opened to inspect, but all equipment is unused in original bags and packaging within the original box. Goes for $295 on ebay and other stores in this condition. Asking $200 o.b.o semi flexible on price. Also willing to allieviate some of the cost in trade if you have other video game/trading card collectables. thank you for looking
