Walker's freedom series earplugs have been meticulously crafted to safeguard your hearing during shooting or hunting escapades. Boasting an impressive noise reduction rating (NRR) of 23 db, they excel in diminishing the intensity of gunshots by up to 23 db. An additional highlight of the freedom series is its incorporation of sound activated compression (SAC) technology. This intelligent feature empowers the earplugs to instinctively compress high-volume sounds to a safe and manageable level, all the while ensuring that these sounds aren't entirely blocked out. This unique attribute facilitates clear reception of range directives and facilitates seamless communication with your shooting or hunting comrades, even amidst the discharge of shots in your vicinity.
