I just bought a new Bluetooth headphone, the Marley Exodus ANC, but it won't pair with my PC (Intel NUC) in Ubuntu 21.04. When trying to connect from GNOME settings, it attempts to pair but it just gives up without an error message.
I also tried to manually connect using bluetoothctl:
$ bluetoothctl

I have another Bluetooth headphone and I can pair that one just fine. And I can pair the Exodus ANC with my Android phone just fine. But I noticed that when pairing the Exodus ANC with Android, Android displays a PIN code from the Exodus ANC, and then I can confirm the pair. It's possible that this PIN code causes pairing to fail in Ubuntu. What can I do to pair this headphone in Ubuntu?

UPDATE 2:
I just tested these headphones on a Dell Latitude 5280 laptop running Ubuntu 20.04, and it was able to pair just fine! The Dell laptop is using an Intel Wireless Bluetooth (device information doesn't give more information). My Intel NUC has a Bluetooth 9460/9560 Jefferson Peak, also by Intel, with which pairing fails. I also have a Lenovo Thinkpad T14, but pairing fails there also. So I bought a USB Bluetooth dongle, the ASUS Bluetooth Adapter USB-BT500, but pairing still fails. What kind of Bluetooth adapter do I need?
UPDATE 3:
Apparently more people are having issues with these Bluetooth adapters:
UPDATE 4:
I bought a bunch of USB Bluetooth adapters, to see if they work. Here are the results thus far:
- ASUS USB-BT500 Bluetooth 5.0: cannot pair
- Edimax BT-8500 Bluetooth 5.0: cannot pair
- TP-LINK UB400 Bluetooth 4.0: can pair, can connect, constant jitter in sound when connected to standard USB 3.1 port (blue port), but sound is fine when connected to USB 3.1 always on port (yellow port).
