Among other possibilities, this could serve as evidence of future AirPods Pro with LE Audio support. Apple`s filing references a Bluetooth 5.3 host subsystem that is likely intended for future products.

In July, the Bluetooth SIG announced that it expects increased availability of products supporting LE Audio by the end of 2022.

It’s also unclear if Beats Studio Buds will add support for LE audio in a firmware update.
