It allows you to experience audio as if it’s coming from outside the headphones, and the headphones seemingly disappear!

In addition, everybody hears sound differently in the real world, depending on the shape of one's ears and structure of the head. The SXFI App’s Super X-Fi technology further uses Artificial Intelligence to map the individual's ear shape and head profile, then utilizes a computationally complex algorithm to transform and custom tailor the audio to each individual, so that it sounds perfect to each and every one, and like what they hear in the real world.
