Actually what you hear is very much affected by what you see!
If the visual is a man talking on a busy street, a "hissy" mic vs a "quiet" mic makes no difference. Your brain will tune into the dialogue and filter out the noise.
If the visual is a static chart or diagram, your brain gets bored and start to pick out the hiss and other imperfections in the audio.
In fact, if the mic is too good and the visual is a man talking infront of a waterfall, the brain will start to notice that the waterfall is too quiet.
So like lighting, there is no good or bad audio, only appropriate or inappropriate audio.
Therefore, it's good to have a variety of mics.
