  • Eartip
    Patent number: 10610413
    Abstract: An improved EarTip may result from the distribution of PTFE throughout a slow recovery foam. Such an EarTip may have a finer, more uniform cell structure that aids in insertion within a user's ear canal. It may also have a smoother skin, with a lower kinetic coefficient of friction, and may provide improved sound attenuation.

  • Long-wearing deep-insertion ear tip
    Patent number: 8573353
    Abstract: Embodiments typically relate to ear tips for sound transmission devices, designed to fit snuggly in the user's ear canal and block external noise from the environment while being sufficiently comfortable for long-wearing and/or deep insertion. Embodiments may comprise a stem and a foam body, with the hollow stem lying on the centerline of the foam body. The foam body may comprise a concave opening in its nose, a rear extension flange projecting rearward to extend its length without significantly impacting perceived comfort, and/or a plurality of indentations about the periphery of the nose of the foam body. The foam body may be formed of polyurethane foam, and the stem may be formed of elastomeric polyurethane.
