AirPods Pro & Max have internal noise cancellation. It doesn’t work perfectly of course, but it’s noticeable when toggling between transparency and NC in a quiet room where I can hear my heartbeat in my ears, when I’m chewing something crunchy, or when I’m using my electric toothbrush.
An inward-facing microphone listens inside your ear for unwanted internal sounds, which your AirPods Pro or AirPods Max also counter with anti-noise.

Theoretically, that could help a little bit, but it won’t change the fact that the ear canal is only the gateway to the organ where hearing actually takes place. Due to bone conduction, the crunchy noises can take a shortcut and bypass the outer ear completely.

It still works pretty well, not as effective as regular external NC of course, but the difference between transparency and isolation modes when chewing crunchy foods or using my electric toothbrush is very noticeable. It’s cancelling the bone conduction sounds, just not as effectively especially in the lower frequency range. Now I’m going to have to do a bit of an experiment with bone conduction headphones from a friend and ANC mode to see how well it’s working.

Sounds really cool. Let me know how that works out.
