an inner ear tip wall defining a sound channel extending along a length of the ear tip from an inner ear tip front end to an inner ear tip back end opposite the inner ear tip front end;
an outer ear tip wall integral with and extending away from the inner ear tip front end to an outer ear tip wall distal end that extends fully around a portion of the inner ear tip wall, wherein the outer ear tip wall is operative to be at least partially positioned within a human ear canal; and
a support body disposed between the inner ear tip wall and the outer ear tip wall;
