Super X-Fi

What's Super X-Fi?

Introducing the world's first external USB DAC and Amp sound card to house the Super X-Fi technology, Sound Blaster X3 redefines your movie experience on PC, Mac and even PlayStation 4.

Critically-acclaimed by respected journalists all over the world and garnering 15 CES “Best-of” awards in 2019, the Super X-Fi technology captures the listening experience of a high-end multi-speaker system set up, and recreates the same expansive experience — with the same original depth, detail, realism, and immersiveness — in your headphones. Not simply a 3D surround technology, the power of Super X-Fi lies in its capability to recreate natural, realistic audio holography that matches your hearing profile, to deliver to you a full theatrical experience.

Featured Questions

  1. What is Audio Balance?

    Audio Balance allows user to control and attenuate the output volume of 2 separate playback endpoints by turning the volume knob in a clockwise/anti-clockwise direction. The 2 playback endpoints on Sound Blaster X3 are Speakers and SPDIF Out respectively. Applying this concept, user can launch 2 different software with one output/playback its audio to “Speakers” and the other playback its audio to “SPDIF Out”.

    User can apply such configuration in various scenarios such as listening to music while chatting with friends on a VoIP software, you will want to listen to the music and reduce the chat volume when the conversation is not of interest to you; or watching a movie while listening to a podcast; or when playing a FPS game with team mates when the game audio over-powers your team mates' chat volume, you will want to reduce the game audio so that you can hear your team mates' chat clearer, or vise-versa.

  2. Why does the Super X-Fi feature automatically switches off when I turn on EQ?

    Super X-Fi is an audio technology that naturally recreates the sound stage of a high-end, multi speaker system. So, users can enjoy the maximum capability of Super X-Fi.

    When Super X-Fi is turned on, the EQ modes will be switched off. Similarly, when the EQ mode is switched on, Super X-Fi will be switched off.
