New bluetooth adapter, this time with BT 5.3 support. For a tenner wasn't expecting huge range etc but really, it manages to maintain a stable connection whilst listening to a podcast on the PC upstairs and I'm all the way downstairs between one floor and 4 walls approx 20-25 metres away, without the need for a dongle with a big aerial, and that is on just some TWS buds. Most impressive.
Best of all, unlike the user reviews of most of the other ones that supposedly don't work on Windows 11 at BT 5.3, this is detected as a Realtek chip and Windows auto installs the Realtek 2023 driver accordingly, the firmware class profile is in device manager LMP 12 which is BT 5.3.
How's the video/audio lag with headphones? I've given up with BT headphones with even on youtube low quality mode.
