I haven’t experienced any ANC headphones that block noise as well as hearing protectors do, but I haven’t tried the newest ones, and it’s hard to test them in a relatively quiet environment (office level rather than retail store level). I wonder if it’s possible to try Airpods Pro. Do you have suggestions of over the ear ANC headphones that block out office noise? I prefer those to sticking things in my ear. It is possible that this stuff has gotten better since last time I looked into it.

Reducing the audio by X decibels is exactly what I want, if I can get X=100. The best I’ve been able to find is around X=30. That helps but if there are ANC devices with higher X, then I’d like to try them. Thanks.
