A Bass Pro Shops and Cabela's Exclusive!Cutting-edge hearing protection, ergonomic design, and high-end performance Walker's Razor Pro Slim Digital Electronic Earmuffs have everything you could ever want. For extra hearing protection, a high-performance digital circuit delivers split-second reaction time, and this automatic sound suppression brings dangerous sounds down to 23dB NRR safety levels. When they're not blocking dangerous sounds, these shooting earmuffs have high-gain, omnidirectional microphones that will pick up low sounds around you, like conversation at the range or wildlife sound in the field, and amplify them into clear, easy-to-decipher digital sound. This high-tech audio is even able to suppress distracting background noises, like wind. Other functions include an automatic shut off after 2, 4, or 6 hours, and an audio input jack lets you listen to music. The Razor Slim design from Walker's is compact enough to fit into any range or hunting bag. The slim, ergonomic earmuffs do not interfere when shouldering and shooting long guns. The redesigned headband delivers all-day wearing comfort. Runs on 2 AAA batteries (included).
