EARMOR M33 EN352 SET Shooting Headset - Black

Shooting Headset with Microphone M33 EN352 SET

Earmor M33 EN352 is a tactical electronic headset with hybrid hearing protection, combining passive noise reduction with additional active filtering of higher frequencies and active amplification of low sounds such as whispers, speech, and footsteps. Designed for professional use.
The headset enhances quiet ambient sounds for superior situational awareness (sound localization, identification) while also mechanically (PNR) suppressing harmful noises above 82 dB, such as gunshots and explosions. This ensures hearing protection even with depleted batteries and allows for clear communication and orientation in hazardous environments.
Using digital circuitry, the headset provides additional noise reduction for disturbances like post-explosion reverberation and offers four levels of active amplification, including modes optimized for different environments. Dual microphones enhance precise sound localization and improve terrain awareness.
The headset features a detachable cable with a NATO 6-pin connector for connection to professional military radios such as AN/PRC 148/152 or with a PTT button (e.g., M52-6PIN-MIL). The package also includes a U-174 (TP-120/NEXUS) adapter for connection with PTT buttons used with more affordable radios like Baofeng.
Additionally, thanks to integrated Bluetooth 5.1, the headset can be connected to mobile phones and other devices, making it convenient for shooting competitions or noisy environments requiring hearing protection. The system is powered by easily replaceable AAA batteries, providing up to 50 hours of operation at maximum amplification and up to 180 days in standby mode.
