The bluetooth antennas on your devices have sucked. I have no problems with my pixel 7 pro. Pairs quickly, play music from across the house, through walls and floors even. Previous phones of mine would lose connection to my bluetooth headphones if my.phone was on the wrong hip, obviously an antenna issue.

Until we can finally kill HSP/HFP, I'm never gonna be happy with Bluetooth. Using a headset mic shouldn't blast you back to the telephone era.

What’s hsp/hfp?

It's the Handset Protocol/Handsfree Protocol that was developed for simultaneous sending and receiving of voice data. They're the only protocols that support sending and receiving voice at the same time, and they do that by sending mono telephone quality audio and receiving mono telephone quality audio.

It's why most gaming headsets, even ones with Bluetooth, include a small RF dongle separately. Bluetooth is technically incapable of high-quality audio when recording.

I'm talking phones to cars (for hands-free and music), mice to desk and laptop, earbuds and headphones to both, keyboards to anything from computers to fire TVs, BT speakers, adapters for older receivers... They all suck. Multiple phones, devices and cars. (although the 2012 Chrysler was the worst so far, and the 2021 Subaru is better)

BT on my 2016 Subaru has been solid. Actually there’s some sort of bad connection in the data path so the BT is more reliable than the wired connection
