Description

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 is 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, allowing it to be used with Smartphones if necessary.

Incorporating an optimised microphone designed 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 included open types (where the user is aware of ambient noise), it is not recommend that these are used with a microphone.
