Forehead Throat Mic for VX-6R VX-7R VX-170 VX-177

The forehead mic transmits your voice by the vibration of your skull. It transmits crystal clear sound without the need to talk before a boom mic. It is attached to an elastic Velcro strap that suits head sizes from 12 to 25 inches.

The forehead mic can be easily hidden under a helmet or cap. You can also wear it on your throat and it could be easily hidden under the collars.

Since the microphone transmits directly from your forehead or throat, it is not sensitive to the background noise. This is exceptionally ideal for usage in high ambient environment such as driving, riding motorcycles and bicycles. Besides, the easily adjusted Velcro strap fixes the position of the sensor / mic so that it would not be misplaced even under constant movement. An ideal choice for hardcore operations.

With the best-quality transparent acoustic tube that could hardly be detected by people around you, this is also ideal for surveillance purposes and security at airports, casinos, crowd control at conventions and concerts, and other working environment requiring discreet communications.

There are two speakers / sound outputs on the forehead mic: the plug for acoustic tube earpiece (provided) and a 3.5mm plug for a pair of standard stereo earphones (not provided).

The plug leading to the two-way radio is also detachable. It is to be connected by a 6-pin mini din plug. The packages comes with the two-way radio plug for the specified models (see specfications on the left). If you would like to work with radios with different accessory jacks, just come and purchase the suitable cables and plug into your throat mic.

We also bundled a finger PTT for you in order to ease the operation of your radio.
