Listen To Your Ears. Hearing protection should never be ignored. EP7 Sonic Defenders Ultra earplugs protect your hearing against noise-induced hearing loss (NIHL) without interfering with your ability to hear routine sounds or conversations. Their foam-tipped stem design, featuring soft memory-foam Comply™ Canal Tips, fits most people and provides a Noise Reduction Rating (NRR) of 28 dB. Sounds at safe levels are allowed to pass into the ear canal, while potentially harmful noises (above 85 dB) are reduced by a proprietary design incorporating a special noise-reducing filter. EP7s include attached filter caps that can be inserted for additional protection and to block out low-level noise in situations where hearing ambient sounds or conversations isn’t critical. They also serve as earpieces for compatible radio communication systems.*
