All valid annoyances, but I really think OP should try using another brand of Bluetooth headphones for a week just to get some perspective of how well AirPods "just work" compared to the competition. Manually having to re-pair once in every blue moon, one earbud playing while the other isn't, no automatic device switching without having to go through the Settings app everytime, A/V desync, dodgy mic quality, earbuds…
Y’know what headphones really did “just work” though? Wired headphones, circa 2017. Their battery life was infinite. You could “pair” them in seconds to any device with a headphone jack, aka any device, because we’re in 2017. Oh, and they were cheaper and better for the environment. Courage, indeed. And this is why I’m currently typing my comment on an iPhone 6S...
I think I’m going to buy 3 of those adapters and leave them where I use my headphones. What a waste.
Wireless changing helps the charge while listening though, so that’s a plus.
