Earmor M20 Active Hearing Protectors - Black

Modern active hearing protectors in the form of electronic earplugs are designed for people who are exposed to or work in high-noise environments. Their compact design, light weight, and advanced electronic hearing protection system mean that the M20 model provides effective protection against harmful impulse noise, while still allowing you to hear ambient sounds and carry on conversations effortlessly. These protectors are ideal for shooting practice, law enforcement operations, construction sites, production halls, and any situation where effective hearing protection is needed without sacrificing situational awareness.

The M20 model features an active protection system that automatically reduces sounds exceeding 82 dB to safe levels, effectively protecting your hearing from both impulse and continuous noise. At the same time, you do not lose contact with your surroundings, and you can communicate freely without having to remove the earplugs.

The protectors provide a Noise Reduction Rating (NRR) of 22 dB and two operating modes, making them suitable for use both indoors and outdoors. The amplification profile for ambient sounds can be adjusted to meet current conditions, increasing both safety and comfort.

The device is equipped with Clear Voice Tracking technology, which enhances speech clarity in noisy environments. This system makes it easier to recognize voices and communicate even in very loud situations, while also efficiently blocking out dangerous acoustic impulses.

Intuitive one-button control lets you quickly toggle functions, allowing for easy operation even when task intensity is high.

The M20 electronic hearing protectors stand out for their exceptionally compact build. The pair of earplugs weighs only 8 grams, so they are virtually unnoticeable even during long periods of wear and do not cause discomfort under a helmet, head covering, or hearing protectors. The M20 model meets IPX4 water resistance standards, providing protection against splashes and moisture in daily use.

The set comes with silicone ear tips and covers in three sizes—S, M, and L—for precise fit to your ear canal. An additional safeguard is the silicone Retention lanyard, which prevents accidental loss during use or movement.

The protectors include 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 earplugs can be quickly recharged using the included portable case with a built-in 300 mAh battery.

The case is charged via a USB-C port, so there is no need for disposable batteries. The device notifies you when the battery is low, and the automatic shutoff function after two hours of inactivity helps reduce power consumption and extends battery life.

• EN 352-2:2002 – The European standard that covers requirements for safety, construction, ergonomics, and the effectiveness of noise-reducing earplugs used as hearing protection devices.
• EN 352-7:2002 – The European standard that sets the criteria for level-dependent hearing protection, i.e., electronic models that attenuate noise while still allowing the perception of ambient sounds and verbal communication.
