Bluetooth 6.2 – more responsive, improves security, USB comms, and testing

Does this finally fix the shitty audio quality when using a wireless headset's microphone?

The trick I'm using (at least on laptops, cannot do this on phones AFAICT) is to change the input device to the laptop's own microphone to get my earphones to not use HFP (Hands Free Profile) and instead stay in a better quality codec (AAC, LDAC, AptX, SBC, whatever your devices agree upon).

Sound quality for my calls on both sides improved dramatically! Since I've discovered this, I tell all my colleagues in our zoom meetings to switch microphones and it's immediately better for everyone on the call (not just the user that was using HFP).

This is because if you use the hands free profile, it'll use a codec that encodes your voice in a terribly bad bitrate, and even worse, the sound you hear in the headphones is also using a terribly low bitrate.

They should finally fix HFP (Hands Free Profile) spec as it's literally impacting call quality for billions of people.

Edit: apparently LE audio is a thing, but device support is still terrible.

HFP has less latency though, doesn't it? And using the headset mic is probably better if the room is loud or has poor acoustics.
