Earmor M33SET Active Hearing Protectors - Black

Professional tactical headset set designed for soldiers, uniformed services, sport shooters, and anyone working in high-noise environments. This model combines effective hearing protection with active ambient sound amplification and advanced wired and wireless communication options.

Durable construction meeting NATO standards and featuring a Bluetooth 5.1 module is suitable both for tactical operations and for use during shooting training, airsoft, or work in industrial settings.

Active hearing protectors equipped with two external directional microphones that pick up ambient sounds and transmit them to the speakers inside the ear cups. This solution maintains environmental awareness, allows conversation, and ensures clear reception of commands while still delivering effective protection from excessive noise.

The electronic system immediately limits sound impulses above 82 dB to a safe level, while quieter sounds are amplified, significantly enhancing situational awareness. The protectors offer a noise reduction rating (NRR) of 23 dB and five-level volume control, allowing easy adjustment to the prevailing conditions.

The M33SET model is intended for use in demanding environments. Its reinforced build features a reinforced battery compartment, silicone loop protection for screw caps, and a lanyard to secure elements against accidental loss or damage during use.

Low-profile ear cups ensure comfortable use with long guns, while the adjustable, softly padded headband provides a comfortable fit even during prolonged wear. The folding design allows the protectors to be quickly collapsed and easily transported in a backpack or bag. Comfort is further increased by replaceable gel cushions that conform to the shape of the head and improve the seal of protection.

The built-in dynamic microphone ensures clear voice transmission, while the 6-pin NATO interface with U-174 lead is compatible with many professional radios used by military and uniformed services.

Another advantage is the Bluetooth 5.1 module, which enables connection to a smartphone without cabling. The user can take calls, converse, or listen to music without removing the hearing protectors.

The fast electronic system in the protectors reacts in under 1 ms, so attenuation of hazardous sound impulses happens instantly on detection. The auto shut-off function after four hours of inactivity extends device operation and saves power.

The model uses two AAA batteries providing up to 50 hours of continuous use. The IP67 rating (complete dust protection and immersion-proof for up to 30 minutes at a depth of 1 metre) allows the protectors to be used even in extremely adverse weather. Additional safety is ensured with a system preventing accidental power-off.
