An ear insert having a funnel-shaped wall defining a tapering channel extending between first and second open ends, the first open end having a diameter greater than that of the second open end, wherein a portion of the funnel-shaped wall adjacent the second open end enables the ear insert to be located within the opening of a user's ear canal, with the first open end adjacent the user's tragus and the second open end facing the user's tympanic membrane, at least a portion of the tapering channel having an acoustic wave reflecting region extending from a location at or near the first open end toward the second open end at an angle of 60°-75° relative to a lateral plane defined by the edge of the funnel-shaped wall at the first open end.
