Razer, the firm that brings us all those high-end gaming peripherals, has made its first foray into the Xbox market with a couple of add-ons. The Onza controller and Chimaera pro gaming headset will be available later this year.

The $50 Onza, with its swanky green trim, has Razer's Hyperesponse Technology, (blah blah fishcakes) adjustable tension analogue sticks and a multi-function button that you can program yourself to perform specific actions. Batteries not included, as they have power cords.

And then there's the Chimaera. Costing $130, it supports 5.1 channel surround sound system, and allows you to connect multiple Razer base stations via its Daisy-Chain cable system. [Techtree.com]
