Works great on Linux, plug and play with the latest stable firmware release for Linux as of July 2021 (or compile the rtl8761b firmware package if it's not up to date ). The A2DP receiver audio is of good quality for listening to audio. Headset quality isn't great, but that's pretty standard with Linux Bluetooth. I still have a more expensive dongle from last year with the same laptop chipset. Work in Windows 10 without having to download drivers.
