The thing though is that it's entirely possible to have a setup with loud monitoring (e.g. performers on stage with floor wedges to hear the music and themselves) using speakers. It works well with directional dynamics and stage condensers close to your mouth, but fails horribly with the omni ECMs on your laptop/webcam several feet away. I love my WFH setup with a dynamic right in front of my mouth and have the system properly rung out so I can monitor myself with no feedback. The cartoid pattern greatly reduces the sound coming from the off-axis speakers and the noise gate takes care of the rest. Obviously this isn't for everyone though and good luck having something this in the office unless you have a room with a door.
