Built-in directional microphones amplify range commands and other ambient sounds to a safe 82 dB, providing more natural listening and enhanced communication.
Adjustable headband for secure fit; compact folding design for convenient storage.
It offers the ultimate in safety and ear protection. The safety is delivered through distortion-free amplification (up to a safe 82 dB) of important low level sounds like range commands and conversation. The protection comes from instant blocking of any noise above 82 dB.
An external audio jack lets the earmuff do double duty as stereo headphones when connected to an MP3 player or other audio source.
The earmuffs are made of sponge, which is specially designed for wearing glasses. The sponge earmuffs have an outer lip that allows you to not squeeze the ear when wearing glasses, and will not change the comfort and noise reduction of the earmuffs. High-quality sponges, whether you need to wear glasses or not, will not change the comfort and noise reduction of the earmuffs.
