Apple has confirmed to T3 that this equipment, sadly, does not include AirPods Pro or AirPods Max. Both of Apple’s elite headphone models only use the Bluetooth AAC codec when connected to an iPhone, which means they can’t receive the full quality of the Apple Music ‘Lossless’ files, which will be encoded as ALAC (Apple Lossless Audio Codec) files.
The earphones will support Spatial Audio with Dolby Atmos for a surrounding 3D effect as will other models with an H1 or W1 chip. Those include AirPods, AirPods Pro, AirPods Max, BeatsX, Beats Solo3 Wireless, Beats Studio3, Powerbeats3 Wireless, Beats Flex, Powerbeats Pro, and Beats Solo Pro.
T3 says it has confirmed that Apple TV and HomePod will support Lossless; however, there are some reports saying HomePod does not. Listening to Hi-Res Lossless tracks will require hardware such as an external DAC.
