The AirPods are the one thing I actually lose (and I've lost a number of times). But I always manage to find them eventually.

The fact that I can't send a sound to them (somehow) when the case is closed is moderately insane. All it can tell me is that they were somewhere near my house when I last used them. That doesn't help me understand where they went to after I put them back in the case and misplaced the case.

This is also my only major complaint (I otherwise love them enough to have upgraded to the new ones when they were released). I would love for the case to be able to beep when pinged by Find My iPhone. Presumably there's cost involved in adding Bluetooth to the case, or adding some kind of communication from the pods to the case, but if it's in the < $50 range I'd probably be ok with it.

Put them in an tpu AirPod case and attach a tile.

Unless they fall out of your ears, which has happened to me when jogging a few times.

That's why I went with the Bose SoundSports. The two ears are tethered to each other, can be clipped to the shirt collar, and securely fit against the concha. I don't see being sweaty and bouncing around on rocky trails leading to anything good with those fancy airpods.

I think this largely depends on ear shape, so those with "funny" ears have a hard time I guess :/
