There is one thing on cell phone audio keeps bugging me for many years, it's the bluetooth connectivity. I used BT earphone since the feature phone era, mostly Nokia. The main problem back then was the earphone either connected to call or media, very hard to have both connected so that I can switch between call and media automatically. That problem had been fixed after few earphones/cell phone changes, but then another problem came in, it is (still now) the multipoint connection.

Multipoint is not new but not commonly known, for example my earily Sony clip BT can pair with 3 devices and switch between them via touch, as far as I know up to 8 devices can be paired in standard BT MP profile. Since I used both a tablet and a phone it's important to have MP on the earphone/earbud. So far I find only Jabra can do that seamlessly, where others need to re-pair or power on/off...etc. The current BT 5.x can do more but I don't see how it works on MP, so that I still stick with Jabra, any comment ?

My Sennheiser PCX 550-II cans are pretty good, I've usually got them paired to the work laptop and my mobile phone they seem to cope pretty well in my use cases. Except when the work Win10 laptop decides to be a d-head and mess with all BT devices.

earphones? My Samsung bluetooth on phone powers this

in my motorcycle shop. Calls cut off the speaker and take over the phone while the app open continues playing music.

My phone updates are current from android though. I have yet to test bluetooth on another expired samsung phone without a sim card.

Edit: If talking Blueman. Depends on my usb dongle. Hit and miss on Blueman applet.

There is a bluez and blutuith app also. GO is my stumbling block in my skill set in my distro.
