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 am unsure if it's possible, it's just a really bad location for a mic. It is somewhat inevitable to pickup background noise so I suspect you would need a lot of signal processing to filter and reconstruct a decent signal.

The form factor doesn't help either, the mics are tiny. Phones have the benefit of a bit more space and a much more practical location.

I think OP is talking about the compression and bit rate, not the placement of the mic.

When the mic is turned on, many headsets go from sounding good enough to sounding absolutely horrible. Something about switching from A2DP to HFP, and sharing the bandwidth between the incoming audio and outgoing audio.

AirPods are impacted much, much less, largely I think because the AAC-ELD codec is decent, and Apple OSes switch the audio from stereo to mono when the mic is on (which seems like a no-brainer IMO, but I guess not all operating systems do this).
