AirPods do not STT announce a low battery unless that's an accessibility setting. By default they just play a little tone to alert you that your battery is low. An argument can be made around the expensive of AirPods but not when it comes to usability, they are bar none. Watching my Android friends cycle though bluetooth headphones like changing outfits is always interesting to me. Every few months I hear about "check out these awesome headphones, they are so small and they have noise cancelling", yawn, I've been using the same AirPods Pro since they released and they've tried 3+ and still aren't happy. I didn't want to believe it and refused to buy AirPods when they first came out until I got them as a gift and reluctantly used them but after I lost them (or they were stolen, still not sure) it took less than 3 days before I had ordered more. They really are magic.
