Once while out on a hike (in early 2020, around mid-March, before Covid shut everything down here) I had my Pods in my ears but my case in that little pocket in the right front pocket of my jeans (keys were in the larger pocket and I didn't want the case damaged by rubbing against the keys) and unknown to me, about a mile and a half into the hike, the case had popped out of that little pocket and fell somewhere. I backtracked about another hour and good thing it was sunny out as the case was quite noticeable in a pile of leaves in the forest. I know I could have bought a new case but I didn't know that much about AirPods at the time and figured they 'paired' to the phone via the case, and had to be used with that case. Either way, I admit to sweating quite a bit while attempting to locate the case!
I've never dropped the pods yet or lose one out of an ear (once a concern I had with true-wireless buds) but the case has sustained quite a few drops but looks ok on the outside. inside, from dirt at work to repeated use of it, the white appearance is more like spotted up with little black marks and dirt I can't seem to remove.
