Patent ID: 8201561

Claim:
An ear tip, comprising: a first annular flange having a base end extending upwardly toward an upper end, wherein the first annular flange has a first non-circular lateral cross section running from approximately the base end to the upper end, the first non-circular lateral cross-section has a first major axis and a first minor axis, the first major axis having a greater length than the first minor axis thereby defining the first annular flange as having a elliptically shaped non-circular lateral cross section running from the base end to the upper end; a second annular flange having a second base end extending upwardly toward a second upper end, wherein the upper end of the first annular flange is positioned such that the second base end of the second annular flange is oriented in a stacked relationship with the upper end of the first annular flange, wherein the second base end of the second annular flange is connected with the upper end of the first annular flange; and wherein at least a portion of the second annular flange is configured to at least partially occlude an ear canal from ambient noise thereby creating at least a partial air seal in the ear canal.
