Company has given out headsets to everyone, but people are impossible to please so most people (myself included) aren't using the official ones for variety of reasons. Plus a lot of it is about the MS Teams which has no software support for noise isolation or cancelling. I can see it clearly when I'm using Discord; if I don't talk, I don't broadcast. In Teams if I am quiet Teams will keep cranking up the volume until some sound AC hum, typing, whatever gets picked up and I am constantly broadcasting.
