I'd recommend lifeproof case, I have the case in white for my 4s. I used it when we went out playing in the snow. The video looks great with good sound. I was able to take a phone call without any trouble hearing the person on the other end, and didnt get any comments about sounding muffled. You have to push a little more firmly on the touch screen, but thats a small price to pay. The external speakers still work great, and although I had to turn it up a bit louder than normal, everything could be heard clearly. The sound seems to resonate off of the back of the case a little bit. Overall, best case I ever had.
