Earphone tip with universal sound port attachment core

An earphone tip configured to be detachably coupled to a sound port of an earbud-type sound device or other sound device, regardless of sound port design, the earphone tip comprising:

• an adapter body extending from a proximal end to a distal end, wherein an internal surface of the adapter body defines a lumen extending through the adapter body along a central longitudinal axis, wherein the adapter body includes a flange at the proximal end of the adapter body extending radially outward from an exterior surface of the adapter body, and wherein the exterior surface of the adapter body extends a first distance radially from the central longitudinal axis adjacent the flange and the exterior surface of the adapter body extends a second distance radially from the central longitudinal axis at the distal end, the first distance being greater than the second distance, the lumen further defining an axially extending proximal portion and a distal portion;
• a lead-in face in the proximal portion of the lumen defined by a distally extending reduction in lumen diameter that aids insertion of the sound tube into the lumen, the reduction in lumen diameter being from a larger diameter of about 4.0 mm to about 8.4 mm at the proximal end of the adapter body to a smaller diameter of about 2.0 mm to about 4.1 mm over an axial length of the lumen of about 0.5 mm to about 1.8 mm;
• and
• one or more retention members in the distal portion of the lumen, the one or more retention members extending radially inward within the lumen, wherein the distal portion of the lumen has a diameter of about 3.0 mm to about 5.1 mm and the one or more retention members extend inward a distance of about 0.127 mm to about 1.5 mm, the one or more retention members located within a range of about 0.8 mm to about 1.8 mm from the proximal end of the lumen.

An earphone tip detachably coupleable to an earbud-type sound device or other sound device, the earphone tip comprising:

• an adapter body including a lumen extending from a proximal end to a distal end along a central longitudinal axis;
• wherein the adapter body includes a radially outwardly extending flange at the proximal end and a longitudinally extending groove formed in an exterior surface of the adapter body from the flange to the distal end;
• and
• a cushion attached to the adapter body, the cushion configured to frictionally engage an ear canal of a user,
• wherein the adapter body is configured to connect securely to any one of a plurality of different sound port configurations of an earbud-type sound device or other sound device.
