Why does ANC feel different on sleep earbuds vs AirPods Pro?
I’ve been using both AirPods Pro and sleep earbuds recently, and I noticed the ANC feels quite different between them.
From what I understand, ANC mainly targets low to mid-frequency noise, and a lot of reviews mention that it’s not a key feature for sleep earbuds since the use case is different.
But in real use with AirPods Pro, turning on ANC gives a very strong sense that overall background noise drops significantly. It feels more like a general “quieting” of the environment rather than just reducing certain frequencies.
With sleep earbuds, the experience seems more subtle and tuned toward overnight comfort and long wear.
Is this a performance difference, or just fit, tuning, or expectations?
