AirPods Pro 3 — Subtle white noise in ANC mode, normal?

Hey everyone,

Just got my AirPods Pro 3, and I’m absolutely loving them — the ANC is seriously next level.
However, I noticed something and wanted to check if anyone else experiences the same thing.

When I’m in ANC mode and in a quiet environment, there’s a subtle but noticeable white noise in the background. It’s not a big deal since I usually have music playing, but when I just want silence — for example, between songs or when I’m trying to block out outside noise — I can definitely hear it.

I didn’t have this issue with my AirPods Pro 1.
Interestingly, the white noise disappears completely when I switch to the “Off” mode (neither Transparency nor Adaptive).

So, is this normal behavior for the APP3, or could my pair be faulty?

Thanks a lot!
