Walkers Game Ear, the shooting and hunting industry pioneer in hearing protection, introduces the Ultimate Power Muff Quads Series with 9x hearing enhancement. The Ultimate Power Muff Quads are equipped with four Hi Gain Omni directional microphones for precise sound detection. They are frequency tuned for natural sound clarity. The recessed volume AFT (Adjustable Frequency Tuning) control knobs allow the user to tune the muff to the frequency position that best matches the users hearing. The independent volume control permits the shooter the ability to dial each side of the muff to a comfortable sound level for each ear. The Ultimate Power Muffs sound activated compression circuit has a reaction time of 0.02 seconds, and through the use of sound dampening composite material it features an unmatched noise reduction rating of 27dB. The Ultimate Power Muff Quads feature a compact folding design, have low profile ear cups, and incorporate a comfortable headband with a metal frame for increased durability. The sound dampening composite housing aids in the protection against harsh noises that damage hearing. The Ultimate Power Muff Quads Series operate on two included AAA batteries.
