Mushroom-shaped push-in foam eartip for use with high-fidelity insert earphones
Certain embodiments of the invention may be found in a push-in eartip assembly. The push-in eartip assembly may include a mushroom-shaped foam tip. The push-in eartip assembly may also include a hollow tube extending through the center of the mushroom-shaped foam tip. An inner diameter of the hollow tube may be constant and an outer diameter of the hollow tube may be tapered. In certain embodiments, the push-in eartip assembly may further include an adhesive for bonding the mushroom-shaped foam tip to an outer surface of the hollow tube. In certain embodiments, the hollow tube may extend through a center hole in the mushroom-shaped foam tip that extends from the top to the base of the mushroom-shaped foam tip.
