If you've ever had a moment when your sound-enhancing earmuffs started whistling in high wind, you know how off-putting it can be. The engineering team at Walkers hates this phenomenon, too, so they developed the Walkers Single Mic Electronic Earmuff to avoid this issue. The one, high-frequency mic used in the muffs is incredibly wind-resistant, and the entire affordable setup provides a noise-reduction rating of 22 decibels. Each pair of Walkers Single Mic Electronic Muffs features a single volume-control knob, as well as 4X hearing enhancement and Sound Activated Compression. The low-profile earcups and folding design allow for a slim, discreet profile that won't impede your shooting or take up tons of room in your range bag. The unit is powered by a single AAA battery.
