摘要：

An improved EarTip may result from the distribution of PTFE throughout a slowrecovery foam. Such an EarTip may have a finer, more uniform cell structurethat aids ininsertion within a user's ear canal. It may also have a smoother skin, with alower kineticcoefficient of friction, and may provide improved sound attenuation.
