Websites like rtings take actual measurements of ANC sound reduction. These don’t correlate perfectly to how we perceive the ANC (because human brains are more sensitive to certain types of sounds), but it should be detectable if something has truly changed.

Users thinking ANC is weakened after a firmware update isn’t limited to the APM and the Bose set.
The author mentions considering the Sony XM5. Same allegations came up with the last update for my XM3. There’s even a GitHub repo with a way to proxy the Sony Headphones app to get the older firmware for a downgrade.
I haven’t noticed the ANC weakening, although I don’t use the XM3 as much for commuting.

💯I bought the AirPod Pros 1st gen the morning they released however many years back. The ANC was phenomenal. I remember the whole experience: putting them in at the store, toggling it on and off while walking along a busy downtown street, and especially in the metro; the ANC was so good you could have had your back turned to the approaching metro and you’d have to think twice about whether you heard the metro pulling into the station. This glorious experience lasted about ten days, and then they released the first post-launch firmware, and the ANC has been far less effective ever since. You’re not crazy.

Every pair I’ve replaced has had problems with crackling every time there was external sound and this starts up within a couple months.
I’ve got three separate pairs, but the ones I’ve given to my mom are my first ones and I bought them without AppleCare two years ago. Would I even be able to still get those fixed under warranty?
