This is the paradox! phone sellers offer hulls, most devices are equipped with shell for better grip and better protection of the unit. The received BELKIN material is very nice and neat, but we must remove the shell of the phone to use it, it's silly! It would be simpler to provide a setting to be able to vary the height of the plug and fit the hull, hull knowing that some are difficult to remove. (Ditto for 3.5 mini jack for audio output problems)
