ASUS and Sennheiser jointly developed the Xonar Xense soundcard-headset combo:
Working together with acclaimed Sennheiser acoustics professionals, ASUS has developed soundcard-headset combo Xonar Xense to revolutionize the way people hear gaming. While most PC gamers suffer from miniscule headphone output, Xonar Xense pumps out a monstrous 7Vrms power through a built-in headphone amp. This brings out every audio nuance in games, movies and music, optimizing sound positioning and audio dynamics.
Games come to life in startling 118dB sound clarity, supporting EAX, DirectSound, Dolby technology and many other standards. The GX 2.5 audio engine drives the ultimate aural experience, making every movement, whisper and gesture tangible as the Xonar range caters to gamers with Game Profile, a utility to maximize audio by genre.
