Filipe Espósito, writing for 9to5Mac:
To make things simple, here’s the hardware needed for each new Apple Music feature:
Lossless: a wired headphone (except for AirPods Max with Lightning/3.5mm cable)
Hi Res Lossless: a wired headphone connected to an external DAC
Spatial Audio: any AirPods or Beats model with Apple’s W1 or H1 chip (Apple says that users can manually enable this option for other headphones)
On a related note, Apple Music Lossless will not work with HomePod or HomePod mini. Spatial Audio will also be available on compatible Macs.
So, why are we hyping up lossless audio then? The Spatial Audio feature sounds neat. It’s already a trippy experience when watching a movie, so I can only imagine how immersive an audio track can be, especially one with live instruments. But, it’s a bit disappointing lossless formats won’t work with products like AirPods Max or the original HomePod.
