ehm no. If you say "all noises up to XX are cancelled" it's just your perception.
Is i say without ANC your ears got (i.e.) 70db at full range and them with ANC that level decrease of 30%, well, it's a bit more solid than your statement.
Rting performed a first test of Airpods Pro 1. And guess what? The average cut is 21db. Exactly the same that I and many other user see with the noise tracking of Apple Watch.
Now, if we assume that the 2nd generation is 2x more powerful than the 1st you easy understand that something might be wrong with this damn update.
