Earmor M20 Active Hearing Protectors - Black

Modern active hearing protectors in the form of electronic earplugs, designed for users who spend time or work in high-noise environments. With a compact design, light weight and advanced electronic hearing protection system, the M20 model effectively protects your hearing against dangerous impulse noise while allowing you to hear surrounding sounds and hold conversations without hindrance. These protectors are ideal for shooting training, law enforcement missions, construction sites, production halls and anywhere that efficient hearing protection with maintained situational awareness is required.

The M20 model is equipped with an active protection system that automatically reduces sounds exceeding 82 dB to a safe level, effectively safeguarding your hearing from both impulse and continuous noise. At the same time, you do not lose contact with your environment and can freely communicate without needing to remove the protectors.

The protectors provide a 22 dB NRR attenuation rating and two working modes – suitable for both indoor and outdoor use. The amplification characteristics for environmental sounds can be adapted to current conditions, enhancing your safety and comfort.

The equipment includes the Clear Voice Tracking technology, which is designed to improve speech audibility in challenging surroundings. This system supports voice recognition and makes conversations easier even in loud environments, while also efficiently eliminating hazardous acoustic impulses.

Intuitive operation with a single button allows quick switching between functions, ensuring easy handling even during intense tasks.

The M20 electronic hearing protectors stand out for their exceptionally compact build. A pair of earplugs weighs only 8 grams, so they’re practically unnoticeable even during long-term use and do not cause discomfort under helmets, headgear or shields. The M20 model meets the IPX4 sealing standard, offering protection against splashes and moisture in everyday conditions.

The kit includes silicone tips with caps in three sizes – S, M and L – allowing precise fit to your ear canal. Added security is provided by the Retention silicone cord, which keeps them safe from accidental loss when moving or working.

The protectors feature built-in batteries with a capacity of 2 x 40 mAh, providing up to 8 hours of operation on a single charge. When discharged, the plugs can be quickly recharged using the included portable case with a 300 mAh battery.

The case is charged via a USB-C port, so there’s no need for replaceable batteries. The device alerts you when battery is low, and the automatic shut-off after two hours of inactivity reduces energy consumption and extends battery life.
