Unlike LifeProof nuud for Ipad, and contrary to what is written on the official site, the shell that I have received is totally unusable in phone mode. Indeed, sound and channel are inaudible. It therefore serves only as a "tight bag" and "anti-shock". It's very expensive waterproof pocket, as buy a waterproof plastic bag, it will be much cheaper. Especially since it takes several minutes to put it on and take it off every time = system useless. CAUTION: The seller refused to take me back the camera in the regulatory deadline (14 days).
