alsa didn't find it yet, probably because it's a HID. More research needed.

It's only seeing native Pi stuff. But that's an alsa thing, not a bluetooth
one. I knew this was a HID device but my phone didn't care, it just
connected to the audio sink in it. That's what I want the Pi to do
too, at least now. But according to the advertising these also have
microphones in them.

Cities are cages built to contain excess people and keep them from
cluttering up nature.
