The prediction engine does not simply pick a match to your ear shape. It uses Artificial Intelligence algorithms to model how sound diffracts from all the folds and cavities in your ear shape. And we do that by extracting thousands of unique identifiers from your ear shape, which are as unique as your fingerprint. As you can imagine, this is not only computationally complex but very intensive, and that's why we harness the power of cloud computing to run millions of calculations - all to model what's unique about your ear and how it changes the sound. Your Personalized Spatial Audio profile emerges literally out of billions of possibilities. It is truly unique and personalized for you.
