Anti-Noise Earmuffs utilize Electronic Sensitive Active Noise Cancellation technology to instantly block out harmful noise above 82 decibels, just like the sound of a gunshot. Sensitive sound pickup technology that amplifies the sound function provides users with clearer, more natural sound and easier communication. Sensitive noise cancellation, using two AAA batteries (not included), helps to cancel the surrounding noise. These earmuffs are ideal for use at shooting ranges or in the field, hunting, shooting practice, and other situations where noise reduction is required, such as garden weeding or machine operation.

Equipped with arc rail mounts, the earmuffs can be rotated freely to save wearing pressure on the ears and are compatible with most FAST helmet arc rails. The external audio 3.5mm jack allows the earmuffs to double as stereo headphones when connected to an MP3 player or other audio source. Gel ear cups are softer and more comfortable, with a better seal and a smooth TPU surface that is easy to clean.

The earmuffs come in a variety of color options, including black, army green, coyote brown, and tan. They are made of ABS material and feature adjustable sound amplification and an adjustable ARC rail adapter version. The noise reduction rating (NRR) is 23dB.

To use the earmuffs, follow these steps: 1. Use a screwdriver to remove the rail bracket. 2. Remove the battery compartment by gently cocking the corner of the battery cover with your fingernail or a thin tool. 3. Install two AAA batteries (not included) correctly according to the guidelines.
