And sure, maybe Apple does make their devices easier to recycle, but there are still 2 R's that are more important: reusing and reducing. If you can reduce the amount of times someone needs to replace their product, you are having a much greater environmental impact than slightly more recyclable aluminum. That's why my Thinkpad x201 is still a more eco-friendly choice than the M1: it's carbon footprint is inherently lower.

Also, a quick bit on the economic strata comment: I come from a relatively lower-income family, but we still did cherish the few nice things we had. My dad passed me down his pair of AKG open-backs with a new DAC for my 13th birthday, and I never really thought of it as that weird. I think your optics are a little out of tune.
The real problem is: For every pair of even $100 headphones, how many $10 headphones do you think are sold? The waste isn't coming from AirPods, it's coming from the $10 set that wasn't designed to last longer than an airline flight
(and yes I'm sure someone will link some cult favorite cheap headphone that's a drop in the bucket compared to how many at the price point are practically disposable)
