The biggest thing that leads to this, I think, is bad audio. Listening to shitty scratchy laptop microphones -- or even the comparatively-excellent Apple array microphones -- is deeply fatiguing. I notice a distinct difference in energy expended when I'm on a call with people who have low/zero background noise and decent-quality microphones, and others have noted that about me (as I'm also an audio engineer in my spare time and tend to have pretty good audio and video in teleconferences).
