How does the voice of performers like Michael Buble come across so evenly despite the varying distance between the microphone and his mouth?

Question

I imagine some of this is done in post-production (for recorded video), but what about live? He is constantly moving his microphone all over the place. Happens a few times during this song, plus lots of his other performances. [https://youtu.be/IMdHqUhfjrQ?t=170](https://youtu.be/IMdHqUhfjrQ?t=170)

Answer 1

Great vocalists have impeccable mic technique. When he’s pulling the microphone away his voice is louder. And when it is closer his voice is softer.
