Is a mono USB headset better for open-plan offices?

Mono can be a smart choice in open-plan offices if you need to interact with people around you as well as, or whilst taking and making calls. It can also matter if you need to hear colleagues, announcements, or a door buzzer while still taking calls. Monaural headsets can also lessens the feeling of isolation, which is a dislike of some users during long shifts. Stereo or binaural headsets are  better when you need to focus deeply, you have a noisy workplace, or you do many meetings one after another for hours. A quick rule of thumb: if you need to talk to people nearby whilst using your headset, go monaural; if you mainly work solo, go binaural.
