The Clandestine is a slim-profile muff with height-adjustment to fit all shapes and sizes. It has a fold-away, padded headband and is powered by two AAA batteries (included). The Clandestine has a NRR rating of 24dB and an omni-directional microphone that picks up the slightest noise and amplifies it through the high definition speakers built into the ear cups. Rapid Noise Suppression technology immediately cuts louder harmful sounds from damaging hearing. The Clandestine is perfect for use at the range, or in the field. It allows the wearer to carry on normal discussions, even at a whisper, and still have total hearing protection when the decibel level gets too high. Wearers find them so comfortable that wearing them all day is easy and second nature. The Clandestine is available in Black and Black Graphite colors.
