That's claimed at many places, but this one claims the opposite: https://habr.com/en/post/456182/ https://habr.com/en/post/456182/, that everything gets (re-)compressed into AAC on the sending device before sending it to the Airpods, in order to mux other audio events. In principle, with end-to-end Apple hardware, they could send multiple streams and leave the muxing to the Airpods, but I don't think anyone has conclusively shown if this is actually done.

- marcan_42 6y agoIf there's one thing I've learned about technical claims about Apple hardware, it's that they are not to be believed unless they come straight from Apple in a precise and unambiguous statement, or from a reverse engineer/hacker who has looked at the code/protocols. The reality distortion field is just as strong as always when it comes to technical details too. People will make random things up to prove that Apple is different or (more) special.
