Walkers Game Ear Isolator Features The Walkers Game Ear Isolator uses Sound Activated Compression and OS-R3110 digital sound processing to protect hearing against sharp retorts like gunfire while amplifying quieter ambient sounds through omnidirectional microphones. This combination delivers a 25 dB Noise Reduction Rating shielding the ears from damaging noise levels without cutting the wearer off from range commands or conversation. Dynamic range speakers reproduce audio clearly so hunters can still pick up subtle sounds in the field like approaching game or snapping branches. Powered by #10 batteries the buds are rated for approximately 60 hours of use before a battery change is needed. Each set ships with baffled silicone and foam earbuds in three sizes apiece along with the patented Secure-Lock sizing fins letting the wearer dial in a comfortable secure fit for extended wear. A removable lanyard carry case and Micro USB cable round out the included accessories keeping the buds organized and charged between uses. The streamlined intuitive design places buttons in ergonomically accessible positions making volume and mode adjustments simple even while wearing gloves or shooting gear. Shooters and hunters wanting premium hearing protection that preserves situational awareness will find the Walkers Game Ear Isolator available for sale at GrabAGun.
