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.

a upper annular flange stacked on top of a lower annular flange, wherein the upper annular flange has a non-circular lateral cross section running from a first upper end to a first base end, the upper annular flange tapering outwardly from the first upper end to the first base end, wherein the upper annular flange is sized and configured to fit within an ear canal to at least partially occlude the ear canal from receipt of ambient noise;
an inner body extending internally from the first upper end of the upper annular flange downwardly and into a first hollow interior defined by the upper annular flange and into the lower annular flange, wherein an interior portion of the inner body connects the upper annular flange with the lower annular flange to allow the upper and lower annular flanges to be stacked on top of one another; and
an acoustic channel extending through the inner body such that sound from a sound source configured to be connected with a lower end of the inner body can pass into the ear canal.
13. The ear tip of claim 12 , wherein the inner body extends into a second hollow interior defined by the lower annular flange.
14. The ear tip of claim 13 , wherein the inner body terminates prior to reaching a second base end of the lower annular flange such that the inner body is positioned entirely within the second hollow interior.
15. The ear tip of claim 12 , wherein the lower annular flange has a non-circular lateral cross-section running from a second upper end to a second base end, the lower annular flange tapering outwardly from the second upper end to the second base end, wherein at least a portion of the lower annular flange is sized and configured to fit within the ear canal to occlude the ear canal from receipt of ambient noise.
16. The ear tip of claim 12 , wherein the inner body connects the second upper end of the lower annular flange with the first upper end of the upper annular flange.
17. The ear tip of claim 12 , wherein the upper annular flange and lower annular flange are oriented along an identical longitudinal axis with one another.
18. The ear tip of claim 12 , wherein the upper annular flange is angled at a predetermined angle in relation to the lower annular flange.
19. The ear tip of claim 18 , wherein the predetermined angle is about 15° to 30° offset from a longitudinal axis extending through a central portion of the lower annular flange.
20. The ear tip of claim 12 , wherein the non-circular lateral cross section may form a shape selected from a group of shapes including an elliptical shape, an oval shape, a triangular shape, or a teardrop shape.
21. An ear tip, comprising:
a first annular flange having a first end and a second end, where the first annular flange has a non-circular lateral cross section running from approximately the first end to the second end, the non-circular lateral cross section has a first major axis and a minor axis, the first major axis having a greater length than the first minor axis, the first annular flange tapering to the first end from the second end;
