The HyperX Cloud Alpha S keeps the best parts of the original, groundbreaking Cloud Alpha, but with additional enhancements and features. Cloud Alpha S features custom-tuned HyperX virtual 7.1 surround sound delivered through its advanced USB audio control box. Bass adjustment sliders have been added to the ear cups so you can fine-tune the bass level of your audio. You can adjust the audio volume, mic volume, mute the mic, and activate 7.1 and now even adjust the game audio/chat balance on the audio control box. The Cloud Alpha S still features the revolutionary dual-chamber driver system which reduces distortion and provides clearer sound, as well as the signature HyperX comfort afforded by the memory foam ear cushions and extra breathable leatherette. Virtual 7.1 surround sound effect output as a 2 channel stereo signal to be used with stereo headphones.
