Similarly there’s a bug when starting the iOS simulator with certain permissions that does this to ALL Bluetooth headsets.

Go to the Hardware menu, Audio Input, and select "Built-in Microphone" as the input. Then input will never use your BT headphones.

I only skimmed the article but I didn't see Bluetooth profiles mentioned:

https://en.m.wikipedia.org/wiki/List_of_Bluetooth_profiles

It's likely switching from A2DP to HSP because the microphone is activated.

This is very common with Bluetooth headsets and it's what still makes me choose corded headsets to this day.

Newest Bluetooth reviews are supposed to have more bandwidth for high quality audio but I'm stuck with (not so) old speakers and car.

If you need wireless, it's better to go with one of those 2.4GHz receivers but they require a small USB adapter. Not really a solution for AirPods.

I will also repeat what has been said about twelve times thus far: Enabling microphone makes Bluetooth headsets turn into pure shit.

Guess what 5.0 finally allows as per spec? You can use any codec you want for telephony mode, including 44.1 stereo + 44.1 mono SBC.

Guess what Apple does not implement, and guess what every 5.0 headset I've seen so far also does not implement? Sigh. Bluetooth is 20 years old this year, and is still a fucking unmitigated trainwreck of unusabilty.

It's likely because the microphone/input channel is being activated - forcing the low-quality audio codec.

Yup, this seems to happen whenever AirPods convinces itself that it needs to use its microphone, which seems to necessitate degrading the audio quality.

I've had this happen with other Bluetooth headphones (Creative Aurvana Gold), my solution was to ctrl+click the volume icon in the menu bar and unset the headphones as Input device

I figured I’d ask this here: my AirPods have never been what I’d call “perfect”, and I’m trying to figure out whether these are fundamental issues with AirPods or if I have a bad pair. Is it normal for AirPods to ignore double taps on them 50% of the time (it’s worse if I try to use Siri, which almost never works, and better if I try to play/pause but still not great)? My AirPods also take up to thirty seconds to swi…

I also find them to be incredibly slow to connect to my iPhone — frequently necessitating going into system preferences->Bluetooth on the iPhone and clicking on the AirPods before the connection finally happens ... it’s a complete mystery to me whether they will be connected when I pull my phone out and put them on at any given time (seems worse with Xs than before - though Xs seems worse generally in all network con…

Im having kind of similiar issues. I foud out that if I last paired them to mac, they will not auto connect to iphone. But if iphone was last paired device, they will usually pair.

Also sound sonetimes go to super low volume and I have to reconnect to get volume up.

Indeed. And you ought to see the vomit the Bluetooth puts over the spectrum. "Noise resistance" my ass. It barely works even when in ideal situations (no wifi, no bt, no microwave ovens).

BT can die in a fire.

Interesting. On Windows 10, it shows a in/out "Headset (AirPods Hands-Free)" and an out only "Headphones (AirPods Audio)." So this transition would be very easy for the user to see. However, I've as yet been unable to get a straight answer on what profile the "Headphones" mode is actually using.

You may find value in this Mac app that disables the microphone input channel on AirPods as part of pairing them, which should in theory permanently resolve your issue: https://c-command.com/toothfairy/ (Note that I neither know how they’re doing it nor have I tried to reverse engineer it. Works well for me in non-VMWare scenarios!)

I have Toothfairy and it is amazing as a quicker way to connect my AirPods to my Mac, but I've tried that option for disabling input and it didn't seem to work for me unfortunately. Still absolutely worth the $3 for the other features though.
