Im on my third pair of Airpods pro (replacement courtesy of Apple) and all of them had the ANC partially fail the longer i use them. I wonder why Apple still release new versions of these whem they cant even get the basics right.

Have you tried replacing your eartips? I find that radically improves performance - I think they must either get clogged or brittle in a way that causes problems.

Cheap foam eartips from Amazon are even better than stock for my AirPods Pro but they need to be replaced more often.

Yep, I wonder why the ANC socialt is so fragile. Turns me off from buying new ones.
