AirPods Max with USB-C finally get lossless audio and wired playback.

Apple Newsroom:

Next month, a new software update will bring lossless audio and ultra-low latency audio to AirPods Max, delivering the ultimate listening experience and even greater performance for music production. With the included USB-C cable, users can enjoy the highest-quality audio across music, movies, and games, while music creators can experience significant enhancements to songwriting, beat making, production, and mixing.

Another key point Apple mentions in a footnote is their new USB-C to headphone jack cable which brings wired playback back to the AirPods Max. The lightning version of the AirPods Max had this advantage, and now the USB-C version gets the wired treatment:

USB-C to 3.5 mm audio cable will be available today for $39 (U.S.) from apple.com/store, in the Apple Store app, and through Apple Authorized Resellers. It can be used to connect AirPods Max to 3.5 mm audio sources, like the audio-out port on an airplane. Users can also connect their iOS or iPadOS device to 3.5 mm audio ports, like audio-in ports on car stereos or other speakers.
