AAA aren't cheap. More importantly, they are annoying to replace all the time.
$79 every few years on a $500 set of headphones sounds plausible, the battery alone would probably be $40-$50 retail anyways; I'm just getting someone at an Apple store to replace it for me.
More concerning is that a set of new ear muffs costs $69. I've already replaced the ones on my QuietComforts two times ($20 using clones on Amazon), so that is going to add up a bit.
Ya, I tried going this route for toys. Frankly i gave up after a few months because they didn’t last as long as the real pain is battery replacement (which requires a screw driver these days because....rules).
