ICM-40S

An inductively coupled wireless earphone for covert security applications as well as broadcast presenters. The ICM 40S incorporates audio squelch which mutes the audio when there is no audio input which reduces the quiescent noise level. These devices have a well defined generic anatomical profile to combine discretion and comfort and are designed to fit in either ear with good audio intelligibility. The wireless earphones have a replaceable wax guard system to reduce problems caused by ear wax. A range of inductive neck loops and inductor packs are available for these products. In situations that require the highest level of discretion and for long-term users we can offer custom fit versions 3D printed from the users ear profile.
