The new standard in slim hearing protection for the shooting range, these Walker's Razor Slim Patriot Series Shooting Ear Protection Muffs were built to be sleek, low-profile, and lightweight, while still providing the world-class hearing protection and amplification that Walker's is known for. With a noise reduction rate (NRR) of 23 dB, these slim hearing muffs let in the noise you need, and none that you don't. Featuring an audio input jack and recessed volume control knobs, the Patriot Series muffs feature a comfortable headband with a metal wire frame that folds down for easy storage in a bag or vehicle. With full dynamic range HD speakers for clear balanced sound and 2 omnidirectional microphones, these low noise muffs provide natural sound clarity that will be right at home at the shooting range, and will even look good in the process.
