1. An apparatus for use with a Behind The Ear Implantable Cochlear Stimulation system, comprising:
- an earhook configured to be removably attachable to a Behind The Ear (BTE) unit of an Implantable Cochlear Stimulation (ICS) system;
a microphone assembly, wherein the microphone assembly includes a microphone having three terminals, and wherein the microphone is configured to be electrically connected to a speech processor of the ICS system using first conductor, a second conductor, and a third conductor, wherein the first conductor is connected to a mating connector and wherein the second and third conductors are connected to a bias setting resistor; and
a bendable, formable stalk having a first end attached to the earhook and a second end directed to the inside of an ear; and
wherein the microphone assembly is attached to the second end of the stalk.

Abstract
An In The Ear (ITE) microphone improves the acoustic response of a Behind The Ear (BTE) Implantable Cochlear Stimulation (ICS) system during telephone use. An acoustic seal provided by holding a telephone earpiece against the ear provides improved coupling of low frequency (up to about 1 KHz) sound waves, sufficient to overcome losses due to the near field acoustic characteristics common to telephones. In a preferred embodiment, the ITE microphone is connected to a removable ear hook of the BTE ICS system by a short bendable stalk.
