Coming from the wired EarPods that I got with my iPod touch in 2012, these AirPods (3rd Generation) feel like magic! I always thought they were a gimmick with presumably awful sound and a constant risk of them falling out and getting lost. But the sound seems just fine to me, nice bass, and have been on a few walks with them and they felt snug enough. Test tomorrow when I go for a jog with them.
The magic bit is with the case, it can charge them up, hold it near the phone and it tells you how much battery is left. I was agog at how seamless it all was.
