Bluetooth headsets - what works?

[ab1jx]

I have a pair of B1 earbuds that I like. Very comfortable for hours. The in-ear part is soft and you turn them into your esars to put them on. Not good for blocking ambiient sound though. There's modern low power bluetooth and an older style, they mostly aren't compatible. A few things can do either. I've mostly only used bluetoothctl.

Pairing is an exchange of key files. Sometimes you can put the files in place by other methods and they're paired..
