Support for spatial audio in hardware from Apple is a novelty that has been available for some time to users who have AirPods Pro or AirPods Max headphones. To access it, you must also have an iPhone or iPad. This function allows you to play the sound in 3D surround mode. This type of sound is available in services such as Apple TV Plus, HBO Max or Disney Plus. Netflix also joins this list.
The latest Netflix update for iOS and iPadOS adds support for spatial audio. However, to use it, it is necessary to have the previously mentioned headphones - AirPods Pro or AirPods Max. To use surround sound, you also need to update iOS or iPadOS to 14 version.
