ED-30761 Knowles Balanced Armature Driver Speaker Receiver for Hearing Aids IEM Earphone
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.
