When positioning the Stealth, the volume buttons on the 
wing should be facing downwards, while the primary but-
ton should be on the left side of the throat and the acoustic 
coil or 3.5mm module attachment should be on right side. 
The optimal position for a throat mic is about 1-1.5” to the 
side of the voice box where the Stealth is positioned.

The  throat mic wing shape was designed for aerodynamic 
applications so that there would not be pressure applied 
to the neck under high wind situations.   Ergonomics are 
comfortable and intuitive to use.

NOTE: 

The transponders should rest comfortably on the neck 

and be in contact with your neck at all times. They should 

not be too tight. The adjustable straps have flex in order for 

to maintain the Stealth in position. Dot not over tighten the 
straps.   

For users with no prior experience with throat mics, please keep in mind the sound quality will never be 
as clear as a standard headset. This is because the audio is created from vibrations of the larynx through 
the body of the throat. Since air is not the medium, nasal sounds will be absent. 

The audio quality is similar to a person with a cold, hence the “muffled” sound that is commonly 
associated with throat mics. The Stealth benefits from a vast improvement of sound quality through 

our in-house advancement.

IMPORTANT

DO NOT WEAR THE THROAT MIC AND STRAP TOO TIGHT AROUND THE NECK.

When worn properly, the neck strap should rest on the back of the neck and only very little pressure 
should be felt

1 to 1.5 in.

New smartphones on the market today have secondary mics, which are used in conjunction to the 
primary mic input for background noise cancellation.   

When using a headset, the device uses the primary mic to compare to secondary mic inputs and 
processes accordingly.   When the throat mic is not worn, the secondary mic provide slight voice 
inputs because no audio is picked up from the throat mic.   However, once the throat mic is activated, 
the audio will perform back to normal.
