Protect your hearing at the range without sacrificing communication capabilities using Walker's Razor Slim Quad Electronic Bluetooth Earmuffs. Bluetooth syncs with mobile devices to keep you in touch while at the range, while an independent, recessed volume control lets you set levels for the Bluetooth signal and external microphones to separate mobile calls and alerts from ambient sound. HD speakers provide high-definition sound quality, and low-profile earcups ensure optimal comfort, without interfering with your cheek weld or stock. The integrated communication microphone lets you talk over your mobile device, and 4 high-gain omnidirectional microphones ensure optimal awareness of your surroundings. These earmuffs are frequency tuned for natural sound clarity, while a sound-dampening composite housing offers a noise reduction rating of 23dB with a 0.02-second sound-activated compression reaction time to safeguard your hearing. What's more, these earmuffs feature a compact folding design with a comfortable headband and metal wire frame for prolonged wear and reliable performance. Runs on two AAA batteries (included).
