Most offerings (eg Apple Music) already has lossless audio for a while, as does Spotify, as it has been supported for the previous generation of AirPods Max already (ie this is not a new feature)
and wirelessly on the AirPods Pro 2.
Why they don’t support it wirelessly on the AirPods Max 2, which should be a superior product to the AirPods Pro 2, is beyond me.
