Earmor M33 - EN352 (light)

The EARMOR M33 - EN352 ligh is an electronic passive noise cancelling headset for special purposes.
Mission. It can enhance subtle environmental sounds and track human voices with high fidelity optimization. It can reduce hazardous sounds above 82 dB to safe levels such as explosions and gunshots, not only protecting hearing but also improving communication clarity and increasing awareness of the surrounding environment. It uses digital circuitry to reduce ambient noise and offers seven levels of adjustable volume to suit different application needs. A binaural microphone enhances ambient sound. The battery cover is designed to prevent accidental drops and features an anti-fall cord, demonstrating Earmor's commitment to the ultimate user experience. This version does NOT come with the 6-pin NATO interface and U174 adapter cable, it must be purchased separately.
This version does not come with a dynamic microphone, it must be purchased. With Bluetooth 5.1 technology, it can be connected to mobile phones and other devices for communication or audio playback, allowing seamless switching between professional scenarios and entertainment. The foldable headband design allows for easy storage and portability.
Listen to the details
The M33 - EN352 features an all-new omnidirectional microphone, high-fidelity speakers and an advanced digital signal processor that enhances overall sound quality. You get clear sound and better situational awareness in noisy environments.
Clear, natural
The M33 - EN352 uses advanced technology to provide more natural sound with improved sound and voice clarity. It is designed for use in complex acoustic environments and is ideal for combat and combat support operations.
Hear and be heard
The binaural microphone has an improved ability to locate the sound source. It features a silicone ear cushion that can improve noise reduction transmission in high noise and windy environments. It is waterproof and dustproof, providing careful protection for your hearing.
Our advantages
Tactical hearing protectors with passive noise cancellation provide hearing protection for combat personnel by reducing the level of harmful noise entering the ear. This type of hearing protection is important for soldiers who are exposed to high levels of noise in combat and training environments. By wearing noise-reducing passive tactical earmuffs, soldiers can prevent noise-induced hearing loss and maintain their auditory situational awareness.
EARMOR M33 - EN352 for today's modern warrior were designed for use in combat and support operations, specifically for use with firearms and ballistic combat helmets.
Listening to the environment
Specializing in advanced listening devices with a focus on environmental listening for military personnel, our state-of-the-art products feature a patented digital audio circuit that improves situational awareness. Our "talk-through" technology allows safe sounds to bypass individual hearing protection while protecting against harmful sounds. The microphone receives sounds from outside and transmits them to a speaker inside the headset, where the digital audio circuitry senses the noise level and compresses or amplifies it to a safe and audible level depending on the level. Sound detection, identification and localization, and speech communication are important components of auditory situational awareness that impact warfighter effectiveness and safety.
