Product details:

This earmuff protects wearers from hazardous noise connected to their environment. This product features built-in directional microphones that amplifies range commands and other ambient sounds to a safe 82dB. Provides more natural listening and enhances communication. Actively listens and automatically compresses amplification when ambient impact sound reaches 82dB. Passively blocks out noise at 22dB. Patented Air Flow Control technology delivers optimal passive attenuation across all frequencies, without increasing earcup size or weight. Constructed with a patented baseplate chamber and high-tech non-woven layer to manage the flow of air inside the earmuff in order to control how sound reaches the ear.
