Over the following years, the company began focusing primarily on its lines of PC and console gaming headsets, steering away from sound cards almost completely (it did release updated versions of the Audio Advantage USB sound cards in 2010). By 2007, Voyetra Turtle Beach had released several headset models including those that were wireless and those that had surround sound capability. Its models were initially designed specifically for the Xbox 360, PC, or Nintendo Wii. Turtle Beach released its first pair of headphones designed specifically for the PlayStation 3 (Ear Force P21) in 2009. In October 2010, Stripes Group acquired a majority position in Turtle Beach.
