A phone case having a bottom wall, opposing side walls, and mouth and ear end walls that form a pocket with an opening having a rim for extending from ear to mouth and around the mouth to hide it from view and to muffle and block beyond the case words spoken into a phone nested therein. A sidewall portion of the rim may have a curved shape conforming generally to the contour of a human face from ear to mouth, and the pocket walls may be made of a flexible, sound absorbing material so that the rim of the opening is sufficiently deformable to conform substantially to the ear to mouth contour and form a sound seal when pressed against a human face. The ear end wall may form an ear portion of the rim for placement over an ear lobe to reduce interfering external noise.
