Engadget - Turtle Beach may have acquired the MLG-endorsement crown that Astro Gaming used to solely hold for its headsets, but it's no matter as Astro has something else up its sleeve: the A50 wireless headset. Announced here at E3, the A50 is essentially the result of embedding the Mixamp 5.8's wireless chops into its flagship A40, finally sparing users of any pesky wiring and external beltpacks.
