The drivers of the Xbox Wireless Headset consists of 40mm neodymium magnets and paper composite diaphragm. Pretty standard for headphones these days. Though it comes with a lot of extra bells and whistles with emphasis on party chat. These include a game/chat balance dial in addition to the volume dial. The adjustable boom mic also lights up when it is turned on.
The Microsoft Xbox Wireless Headset is set to launch on 16 March, for a price of US$99.99 (~RM404). That being said, it will likely not be made official here, the same way the Xbox consoles are not brought in officially by the company.
