Important thing to note with AirPods is that it’s not just the batteries that deteriorate. All of the membranes and meshes and everything lives in a constant chaos of heat/cold, grease, shocks from being dropped, etc. If you get a new pair of AirPods Pro after two years they sound significantly better than the old pair. I’m on my third pair and I never once bought a new one because of battery life/failure.
