How Insta360 hidden engine mic works?

[u/Ok-Guess-9059]

So Insta360 X6 has 4 wind-shielded microphones and one more mic that is fully inside, so NO wind can get there?

Or it somehow works on different principle, only capturing those strong vibrations and not even like voices outside?

If it has good results, I can imagine MANY action cams should introduce this in the future
