An improved ear tip for earphones and hearing protection is provided where comfort and occlusion of the ear are of most importance. The ear tip comprises an elastomer polymer resin material molded to form the material to the shape of the ear canal. A chamber is defined having a proximal and distal end, the distal end engages the acoustic exit of the transducer, sound source or sound attenuator and the proximal end of the bore is adapted to be disposed adjacent an eardrum. The inner body attaches to a nozzle, or audio playback orifice to naturally transition the acoustics from the transducer or sound attenuator to the eardrum via the ear canal. The ear tip can have a plurality of flexible annular flanges disposed at spaced intervals of the body with decreasing circumference as the flanges transition to the proximal end. Each flange tapers in a radius or curvilinear geometry as it progresses to the end of the object.
