Then its a problem with leadership, not WFH. If you don't test the product how you should test it, you need to get fired if you don't do your job.When people are WFH, they are less likely to be out and about in the real world doing a thorough test of AirPods features and functions.
When you go into the office, you're more likely to go out to eat lunch, take coffee breaks, etc. Those are great opportunities to test ANC and Adaptive Transparency. But if you're WFH, you're less likely to find yourself in places and situations where there's a lot of noise.
If you're WFH, you might be less inclined to go outside (to take a walk, exercise, run, bike, etc) where you'd be able to test sweat/water resistance (in addition to ANC and Adaptive Transparency) since you can just hop on yourPedalonPeloton and exercise indoors.
Every argument that WFH is bad is just pointing out how awful Apple is. Bad management, lack of proper QA testing etc. Not WFH being the issue.
