Pro Ears Gold Electronic Hearing Protection & Amplification – NRR 26. The Gold II Series is the updated version of the Pro Ears Golds without the ear jacks. Pro Ears Golds remain to be the world’s most advanced electronic ear and hearing protection in many applications, including in shooting, hunting, and industrial settings. With a NRR of 26 dB, these earmuffs protect your ears in loud environments like the shooting range, parades, concerts, sporting events, and more. Pro Ears offers the only hearing protection with dual, fully-enclosed military-grade circuitboards with gold connectors, allowing for independent volume control. Separate controls are especially beneficial to those who need to compensate for hearing loss in one ear or to increase situational awareness. The Golds also feature the world’s only DLSC Technology (Dynamic Level Sound Compression) with FSS (Full Spectrum Sound) for a clean and natural uninterrupted sound and hearing protection while allowing softer sounds to come through as well as eliminate tinny noise. Sound is amplified up to 8x with high fidelity and has a quick 1.5 millisecond response time. The Gold II Series uses 4 AAA batteries (not included). A low battery indicator and auto shut off after 4 hours of non-use prolong battery life. The foam-padded, easily adjustable headband is comfortable for all-day wear and gel ear seals provide comfort and durability in both hot and cold conditions.
