Abstract
A removable component for use with an earphone is disclosed. As an example, the removable component can be an ear tip. According to one aspect, an improved ear tip can be provided for use with a headphone. The ear tip is suitable for in-ear operation and can have a cosmetic deformable outer member. The deformable outer member can enable the ear tip to readily conform to a user'"'"'s ear. The ear tip can also include an inner member to structurally support the outer member and to facilitate attachment to a headphone. Methods for forming such ear tips are also disclosed.

26. A method for forming an ear tip, the method comprising:
-
providing an inner structure for an ear tip; providing a top mold having at least one protrusion; providing a bottom mold having an ear tip cavity; depositing a quantity of a second material into and/or adjacent the ear tip cavity so as to form an outer structure; coupling the top and bottom molds together with the protrusion being inserted into the ear tip cavity; curing the ear tip being formed within the ear tip cavity; after the curing, removing the to mold; removing excess portions of the first material and the second material from the formed ear tip; and removing the formed ear tip from the bottom mold, wherein the inner structure of the formed ear tip comprises an elastomer of a first hardness and wherein the outer structure of the formed ear tip comprises an elastomer of a second hardness, the second hardness being less than the first hardness. - View Dependent Claims (27, 28, 29, 30)
