Listening to silence?

[Wando64]

Does any AirPods Pro owner use them to listen to silence?
Basically, is it possible to take advantage of the active noise cancelling feature without listening to any music, and is it effective?
How effective, compared to, say, foam earplugs?

They are very effective even if you just want to silence your surroundings with no music playing but they only filter mid range and lower frequencies. Higher frequencies or higher pinched sounds are further hearable
