ED/FED series balanced armature speakers

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 it a robust receiver for many applications. FED receivers also damp acoustic peaks and reduce vibration to solve feedback problems and closing issues in ITE hearing instruments.
