Until battery life starts deteriorating any that happens real soon and you can’t even know when it started and where it is currently unlike that of, say, an iPhone. Then it’s unusable — hurrah, buy a new pair. The Apple way! :)
This is not unique to Apple. All headphones with tiny batteries in the drivers take the piss after a few years aging.
That said, my MacBooks have the best laptop batteries of any computer I’ve owned. My wife went through multiple laptops in the time I kept one in college. Turns out some electronics just suck!
