<P> The Xbox 360 controller is the primary controller for the Microsoft Xbox 360 video game console and was introduced at E3 2005 . The Xbox 360 controller comes in both wired and wireless versions . Original Xbox controllers are not compatible with the Xbox 360 . The wired and wireless versions are also compatible with Microsoft PC operating systems, such as Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10 . </P> <P> The wireless controllers run on either AA batteries or a rechargeable battery pack . The wired controllers may be connected to any of the USB ports on the console, or to an attached USB hub . </P> <P> The Xbox 360 controller has the same basic familiar button layout as the Controller S except that a few of the auxiliary buttons have been moved . The "back" and "start" buttons have been moved to a more central position on the face of the controller, and the "white" and "black" buttons have been removed and replaced with two new bumpers that are positioned over the analog triggers on the back of the controller . The controller has a 2.5 mm TRS connector on the front, allowing users to connect a headset for voice communication . It also features a proprietary serial connector (which is split into 2 parts on either side of the headset connector) for use with additional accessories, such as the chatpad . </P> <P> On August 31, 2010, Microsoft's Larry Hryb (a.k.a. Major Nelson) revealed a new design of the Xbox 360 controller which is set to replace the Wireless controller bundled with the Play & Charge Kit . Among small changes such as the shape of the analog stick tops and grey - colored face buttons, the new controller features an adjustable directional pad which can be changed between a disc type D - pad or a plus shaped D - pad . The control pad was released in North America exclusively with Play & Charge Kits on November 9, 2010 and was released in Europe during February 2011 . </P>
