> This means there is great opportunity for Linux users to control their Bluetooth headsets, which for example is quite nice in an office setting to toggle "hearthrough" when toggling volume "mute" on your machine.

Fun fact: There are at least two applications that reverse engineered AirPods' communication protocol for custom controls - AndroPods from 2020 [1] and LibrePods from 2024 [2].

But... mainstream Android has a bug open in their Bluetooth stack for well over a year now that prevents issuing the commands, meaning to actually use the app you need root rights [3].
