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.
