I have the TP-Link UB500 V2 and it works flawlessly on my PC with Fedora. I use it to connect my phone for making phone calls, and also to connect my wireless headphones and my dualsense. No problems whatsoever. It supports Bluetooth 5.3 and has the aptX HD codec.
The only problem I noticed is that if I do bluetooth tethering with my phone, the audio (from my phone to my computer) lags a lot, but I guess that’s normal because the tethering uses up bandwidth meant for the audio transmission.













And what about Xenia?
