AAC and Debian
Currently, in a default installation of Debian with the GNOME desktop,
Bluetooth headphones that require the AAC codec1 cannot be used.
As the Debian wiki outlines,
using the AAC codec over Bluetooth, while technically supported by
PipeWire, is explicitly disabled in Debian at this time.
This is because the fdk-aac
library needed to enable this support is currently
in the non-free
component of the repository, meaning that PipeWire, which
is in the main
component, cannot depend on it.

Such as, for example, any Apple AirPods, which only support AAC AFAICT. ↩
