Isn't Bluetooth multipoint what you're looking for re: intelligently switching Airpods? There are a decent number of non-Apple Bluetooth headphones that can do that with any manufacturer's Bluetooth capabilities (it even works switching between an iPhone and a non-Apple laptop!). For example, the extremely well reviewed Sony WH-1000XM4 can do it — those are over-ear headphones, not the earbuds, but Sony announced that they're updating the earbuds (the WF-1000XM4, to use the nearly-inscrutable Sony product name) to support Bluetooth multipoint too — as well as earbuds and headphones from Anker, Panasonic, etc.
I own the Sony headphones, and the multipoint stuff isn't great. If I as much as get a notification on my computer it'll mute my phone playing music, I can't be in "high quality audio mode" while talking (Bluetooth ext that doesn't seem implemented).
It works, but in my day2day I Bluetooth with my phone, join meetings on both Android and Linux at the same time.
