Surefire EarPro EP4 Sonic Defender Plus

EarProTM by SureFire® Sonic Defenders are designed to help protect your hearing without interfering with your ability to hear routine sounds and conversation. Safe sound levels are allowed to pass through unchanged, while potentially damaging noises (above 80dB) are reduced using a proprietary design incorporating the patented Hocks Noise Braker® filter. This enables the Sonic Defenders to convert harmful sound levels into insignificant amounts of harmless heat energy. And when you require even more hearing protection, without the need to hear routine sounds or conversations, insert Sonic Defenders’ attached stopper for a Noise Reduction Rating (NRR) of 16dB, 19dB NRR for Sonic Defenders PLUS. Made from soft, hypoallergenic, medical-grade polymer, the contoured helix shape conforms to the natural groove of the ear for comfortable, all-day wear, while holding the earpiece securely in place. Their low-profile design means you can keep them in place while wearing a helmet, mask, or hat, or while using the phone, a headset, or supplemental ear muffs.
