Tactical Sound Control™

Proprietary technology that amplifies sounds you want to hear up to 8x their natural volume, while still protecting you from harmful gunshot noises in under 2 milliseconds.

25 dB of Noise Reduction

Most gunshots register between 150 - 170 decibels, which can quickly damage your hearing. Combat those dangerous noise levels and shoot safely all day long.

Lightweight & Comfortable

At just 15.5 oz, this earmuff is nearly a half pound lighter than other leading tactical earmuffs. Enjoy all-day wear with a vented headband and memory foam ear cushions.
