I received this from Amazon a few minutes ago:
ESR Case compatible with AirPods Wireless Charging Case, Shock-Resistant Protective Cover, Soft Slim Fit Silicone Skin
www.amazon.com
I have to say that I'm not totally hating it. The first ESR case I got was the rippled one that was clear and then had the bumps on the inside to keep it from having the sticking marks. It added a ton of bulk and the top would not stay on the top of the AirPods Pro case, even if I didn't touch it or move it. With this one, I see some people saying it's too flimsy and thin, but I think that was intentional in order to not add bulk, and it is a much better fit and feel.
I like that they added some extra bumps at the corners to absorb shock, and I like that the top of this cover kind of suctions itself on. In fact, it's kind of hard to get it on straight without starting all over because it's so quick to stick itself on the top. It might take you a few tries. In any event, at least for the unit I got, I don't see the top coming off on accident, even when going in and out of a pocket.
I do like the plug for the charge port--I tend to charge via Qi, so the port becomes more of a liability for water damage than anything else. I also think that the color on the Amazon picture accurately matches the color I received.
For $8.99 this isn't bad, and I might actually just stick with it. I want to see how it does over the weekend. To hedge my bets, I do have a different one coming on Tuesday from a generic Chinese website--I paid $10 for it so I figured it wouldn't hurt to have a spare even if I don't like it.
