I used my Bluetooth headphones for several days, listening to music and watching videos. There is only a problem with the wifi speeds with one router. With ISP's HG6544C router: Official driver: 3/5 Mbps. rtw88: a bit more, but not steady at all. Not enough to watch a 1080p Youtube video. With my D-Link Eagle R32 router running Openwrt, on the same channel: Official driver: 6/10 Mbps. rtw88: download starts around 30, climbs to 50 / upload is 10 Mbps. I can watch a 1080p Youtube video. The music doesn't cut out during any speed tests. I also tested transferring files to and from my phone. I don't have other types of devices to test.
