ED/FED series

Knowles’ most versatile and most popular receiver, the ED series powers applications ranging

from Standard BTE aids and Mini-BTE aids to Full Concha and Half Concha ITE instruments.

The ED is made even more functional by the addition of ferrofluid. Its shock survivability makes

vibration to solve feedback problems and closing issues in ITE hearing instruments.
