In 1490, Leonardo Da Vinci created the first sonar system.
This revolution in science was embraced and paid tribute to starting in 2007 with the ASUS Xonar.
Inspired by Da Vinci's quest for innovation and excellence, Xonar products have been developed with the same mindset:
to explore an uncharted world of sound and allow people everywhere the great audio experiences
they deserve via pure, uncompromising hi-fi.

Why Choose Xonar Audio Cards1?

With the continued growth of digital entertainment, PCs have become the heart of personal and home multimedia. To achieve the best experience, audio is just as important as video and computing power. Integrated audio on motherboards has to struggle with limited space, complicated board layouts and cost considerations, constraining the performance of headphones and speakers. In contrast, the improved audio quality and sound effects provided by dedicated audio cards allows you to discover previously unnoticed details in your favorite songs. It offers you precise audio intelligence for multiplayer gaming, and helps you immerse in true cinematic excitement on your living room screen.
As the world's leading audio card brand and PC hi-fi master, Xonar always caters to the needs of audiophiles, gamers, and movie enthusiasts in every situation.
