What’s the status of audio on modern Bluetooth? The only decent mic+audio configuration I’ve ever experienced is AirPods on apple devices, anything else sounds terrible when the microphone is activated.

I found it to be a headache trying to get LE Audio to work on my Windows machine. It should provide good audio quality when the microphone is in use but:

- I have to have BLE v5.2 at least on my Windows device - It must have isosynchronous audio support (which I believe is an optional feature in the spec)

- The headset must have the same features too.

Then it is a question of which audio codecs are supported on those 2 devices. It's quite messy to be honest.

On Linux it is even worse: there is apparently no USB dongle that would support isochronous audio and recent enough BLE versions. Only some very limited selection of newer PCIe Wi-Fi cards.

Works on SteamOS out of the box and with all the features as far as I can tell.

That dongle has its own Bluetooth stack and is exposing a standard audio device via USB. Indeed that currently seems to be the only way, but then the stack need config input somehow, which in case of this one requires a proprietary Win/Mac Software.
