I have absolutely no experience with Bluetooth. Goggling for
Ubuntu+Bluetooth came up with
https://help.ubuntu.com/community/BluetoothSetup
In "Requirements" they say "Think Penguin" "explicitly provide support for
Ubuntu"
https://www.thinkpenguin.com/.../penguin-usb-bluetooth-micro-adapter
It claims to have a 20 m/65 ft range and work with Linux.

Most of the time the headset will be within arms length of the computer.
While a good solid connection at 10 ft would work 99% of the time, but you
know how it is, that one time when you are out of beer or about to wet your
pants because OF the beer...

Both of the items are Bluetooth, at least they claim to be. I have no doubt
they are. I have used Newegg for over 10 years and Think Penguin I got from
Ubuntu.com.
