Spatial audio:

The spatial audio of iOS 14 supports dynamic head tracking technology, which brings a cinematic experience to AirPods Pro. By applying directional audio filter and fine-tuning the frequency of binaural reception, spatial audio can virtually place sound in any direction of space, providing an immersive surround sound experience.

Using the gyroscopes and acceleration sensors of AirPods Pro and iPhone, spatial audio can track the movements of the user's head and equipment, compare the movement data, and then remap the sound field. Even if the user's head moves, the sound field can still be located at the user's equipment.
