I use them daily on a computer for several hours on calls. They have very good sound quality and a great microphone that isolates external noises. They connect instantly when using the dongle, I haven't tried them with the computer's Bluetooth. The few times I've used them for music, they have satisfactory sound but nothing impressive. They are compatible with teams, SfB, and Skype, and have been playing without any issues for several months. Their signal is good, but if there are several walls and a distance greater than 7-8 meters, they start to lose connection.
