The full range HD speakers and omnidirectional microphones deliver clear, balanced sound, while the soft headband makes for comfortable wear. For added convenience, these Walker's muffs feature an external battery door so you can easily change the batteries. Built for comfortable all-day wear, the Walker's Razor Slim Electronic Muffs come in a variety of color options to protect your hearing while at the shooting range.
