Ear impression

To produce custom fitted Serenity protection an accurate impression of the user's ear canal and outside ear is taken.


This ear impression is used to produce comfortable clinical nylon eShells. With these in hand, the user can choose the Serenity system that best suits his needs.


Phonak’s earJack is a standard mechanical interface that clicks into an eShell, forming a perfect seal. The earJack contains different electro-acoustical components depending upon the Serenity system chosen.
