The Razor Muff has two Hi-Gain Omnidirectional microphones that enhance sound detection. They are low noise and frequency tuned for natural sound clarity and the recessed volume control knobs allow the user to tune the muff to the frequency position that best matches the user's hearing. The independent volume control permits the hunter the ability to dial each side of the muff to a comfortable sound level for each ear. A sound activated compression circuit has a reaction time of 0.02 seconds and through the use of sound dampening composite material, the Razor Muffs feature a noise reduction rating of 22+dB. The Razor Muff has a folding compact design, ultra low profile ear cups and incorporates a comfortable headband with a metal frame for increased durability. The sound dampening composite housing aids in the protection against harsh noises that can damage hearing. Operates on two included AAA batteries.
