It's appears to be binaural sound. This is not a new technology. When you listen to music, or sounds, that are recorded this way, through headphones, it gives "direction" to the sounds. They use a dummy head with microphones on the "ears".

Apparently, this is a "new age" (rhymes with "sewage", lol) company. The sounds that they record (and sell) are probably used to facilitate meditation.

Here's another company that is marketing products using binaural:
