EMS Earmic System

Ear Microphone Headset

A headset incorporating an earphone and an optimised in-ear microphone for applications where it is impractical or impossible to use a microphone boom, but clear and precise communications are essential for safety, instruction and conversation. It can also be used in surveillance situations as the appearance of the headset resembles a standard consumer entertainment system and can be used with Smartphones if necessary. Incorporating a microphone equalised to respond to speech from the ear canal and a high quality earphone, the headset can fulfil the demands of a number of applications including communications within a CBRN (chemical, biological, radiological, and nuclear) type of protective suit/respirator, public order personnel and situations where a boom microphone may be impractical or unsuitable. The headset can be supplied as discreet items or wired together on a Y cord. A wide range of eartips are also available. Rubber earhooks are also supplied to guide the cable over and behind the ear for added security and user comfort.
