I don't think you are giving these 2 products enough credit.
As for the MacBook, M1 MacBook Air is based on a 3rd generation design (2018) that enabled some improvements (smaller bezels, smaller footprint, Touch ID) but also some regressions (no 3rd USB/TB port, no MagSafe, no SD slot).
The 4th design could be more than just a fresh new coat of paint. MagSafe is all but assured, as well as few other surprises (and probably also the controversial Center Stage camera).
As for the AirPods Pro, it is rumored to significantly improve the noise cancelling algorithm. Coupled with the possibility of it using an alternate radio (UWB?) for lossless audio and redesign that could improve comfort, it could be a massive hit. AirPods 3 hasn't been the success Apple had hoped, so I think Apple is putting extra efforts to make it succeed.
