Apple has confirmed that none of the AirPods will be able to play lossless audio from Apple Music. Literally, none of them.

It is always interesting how Apple phrases things in its press releases. Everyone believed that AirPods will be able to stream lossless audio over Bluetooth from Apple Music, even though that is technically impossible due to the high bandwidth required and is something which Bluetooth cannot handle.
