The EARMOR M31 PLUS electronic earmuffs are digital noise-canceling headphones designed for hearing protection during daily shooting training.

They can suppress noises exceeding 82dB, such as explosions or gunshots, while simultaneously enhancing ambient sounds. They improve the perception of speech, movement, aircraft, vehicles, weapon operation, and gunshots.

The modular design allows adaptation to different suspension systems, while the gel ear cushions seal around the ears to block noise and are resistant to wear.

The EMI system effectively filters electromagnetic interference. An AUX 3.5 mm audio cable allows connection to multimedia devices for a better experience.

• Volume adjustment in 5 levels.
• Ultra-sensitive detection of environmental noise with a quick response time.
• EMI/RFI shielding system for the suppression of electromagnetic noise.
• Dynamic speech detection technology for improved audio clarity.
• Comfortable gel cushions that prevent sound leakage.

The Noise Reduction Rating (NRR) is NRR22dB, indicating that the higher the number the more noise is reduced.

Their construction is lightweight and durable, powered by two 1.5V AAA batteries with up to 60 hours of operation. They feature a 3.5 mm audio input port for connection to other devices.

The waterproof design competes with adverse weather conditions.
