I highly doubt these new headphones with non user replaceable batteries would survive 2 years of daily usage, that would be 2+ full cycles per day for the airpods, seeing how tiny the batteries are I don't think they'd perform very good after even a year
I like the headphones because they don't wear me down on long continuous usage and the sound is great to my not-golden-ears.
They cost about 350 euros back then and now perhaps paid 50 euros to get them back into shape, so pretty good for a music lover. I have even used them in office space, even though they are semi-open. Luckily the sound isn't leak too noisily on my usual listening levels.
I get that earbuds' 5-hour listening time is borderline annoying and if it drops to 3 or 4 hours you've got a real usefulness problem, but 20 hours has quite a lot of headroom for battery degradation unless you don't sleep.
That said being able to just buy a new cable and whip the old one off is far nicer than having to buy a whole new pair of headphones.
I replaced them with cheap knockoff cables and they're lasting much longer. I haven't replaced them for years now
Meanwhile, I'm on my third replacement airpods (thankfully all covered by warranty, but not much longer!)
