With the APP3, they are largely the same except with the louder tools (circular saw, cordless grinder) they produce a horrific feedback instead of canceling the noise. So much so that I switched back to my APP2 (which do not have this issue in back-to-back testing).
This REALLY irks me, as the APP3 are what forced the upgrade to iOS 26 (which is terribly misguided and under-baked), so I'm stuck with all of Apple's foibles and none of their wins.
Feel like I got punched in the gut and my lunch money stolen. Not a good feeling Apple.
