Don't think this is new. I have bose supersport, been using it for a couple of years perhaps. Battery lasts weeks, connects to both my work and personal phone as soon as I turn it on, and hit play on either device. And, I don't remember ever facing any connectivity issues either, just works since the day I paired.
I am not sure what other features airpods have but if this is "the" feature, you can have it even in products for about a fifth the price since years.
