Perfect waterproof & shockproof

It appears to be. As I said, the case is as represented in that it is very sturdy. They are real waterproof, shockproof, etc. I was worry about that it seems will affect the clarity of our voice in phone conversations with friends. But actually, they keep saying that they don’t have trouble hearing me clearly after we fade in and out several times. They tell me how much better they can hear me. That’s a shining point of this product for sure.
