It is frustrating how opaque bluetooth is. A lot of regular folks would have no idea that getting a newer Mac would improve their airpods microphone quality.

For what it's worth I have found the NC 700's to have a much better microphone quality when in self voice mode. It's explained here: https://www.gearpatrol.com/tech/audio/a594565/bose-noise-can...

Improve? Mic, perhaps, but my range and connection reliability have gone down the toilet with a new Macbook air, compared to my pre-USB-c version. I can’t get more than 3’ from it without the audio cutting out. The same headphones can get 100’+ with my iPhone SE.

Yes the microphone was better. My Bluetooth 4.0 adapter still resulted in an 8kHz duplex connection to them though

It seems like your server can't handle the traffic.

In case anyone cares, the Jabra Evolve2 85s arrived today. They definitely sound worse for music listening but I'll keep them because the USB Bluetooth dongle fixes the 8kHz problem, they work wired over USB and they cut out the event noise in the house. YMMV.

Do you use the Fenvi bluetooth adaptor or an Bluetooth chip pulled from a genuine Mac? The fenvi adaptor in my experience is bad, it have high interference.

It's a good article, thank you for writing it!
