Abstract
An ear tip connects to a nozzle of an earphone. The ear tip comprises a body having a lumen extending from a rearward opening to a forward opening, the rearward opening being sized and dimensioned to connect to the nozzle so that sound transmitted out of the nozzle passes through the lumen and is transmitted out the forward opening. The body comprises an inner core forming at least a portion of the lumen and an outer cover covering at least a portion of the inner core, wherein the inner core is made of material sufficiently rigid to avoid deformation when the ear tip is inserted into the ear canal of a user and the outer cover is made of a material less rigid than the material of the inner core and capable of being compressed and deformed by the ear canal when inserted thereinto. In one version, the inner core and the outer cover are arranged so that when the ear tip is inserted into an ear canal and the outer cover is deformed by the ear canal, the forward opening has an area equal to or greater than the area of the rearward opening. In another version, the inner core has a forward end opening larger than a rearward end opening of the inner core. In another version, the outer cover comprises a rearward segment, a forward segment sized or shaped differently than the rearward segment, and a connecting portion connecting the rearward segment and the forward segment and which allows the rearward segment and the forward segment to flex relative to one another.
