NIB stands for Natural Interactive Behavior and is short-range, headset-to-headset communication in high noise environments without the use of an external communications radio. The NIB function allows for 4 team members to speak simultaneously and over 60 people to listen within a 5 meter radius. Audio transmit is activated by either a voice activated switch (VOX) for hands-free operation or by a push-to-talk button. A tactile button on the left ear cup easily allows the user to turn the VOX function on or off.

MAP stands for Mission Audio Profiles and is advanced environmental listening settings that optimize the amplitude and frequency for specific conditions. The Mission Audio Profiles have been designed with a variety of combat and combat support operations in mind. The environmental listening feature, also known as “Talk-Through”, uses a proprietary digital audio circuit that allows safe audio sounds to bypass the hearing protection while still helping protect against harmful noises.

Yes! The new boom mic design accommodates both left and right hand shooters without needing to relocate the microphone to the opposite side of the headset.
