Protecting your hearing doesn't have to mean sacrificing the ability to hear routine sounds or conversations. The EP7 Sonic Defenders Ultra are designed to provide a Noise Reduction Rating (NRR) of 28dB while still allowing safe levels of sound to pass through into the ear canal. The foam-tipped stem features soft memory-foam Comply™ Canal Tips which fit most people comfortably. Harmful noises above 85dB are reduced via a proprietary design that incorporates a special noise-reducing filter, and there are also attached filter caps which can be inserted for additional protection and to block out lower-level noise, such as on a plane. The Sonic Defenders Ultra are made from a soft, hypoallergenic polymer for all-day comfort and extended product life, and their patented EarLock® retention rings ensure they stay in place. The low-profile design also means they can be worn while using a helmet, mask, phone, headphones or supplemental hearing muffs. Additionally, they can serve as earpieces for compatible radio communication systems simply by removing the noise-reducing filter and attaching the earpiece to the system. Please note that if the noise-reducing filter is removed, EP7 earpieces do not provide hearing protection. The Sonic Defenders Ultra are available in clear, black or orange and come complete with a 26" polymer lanyard and an additional pair of Comply™ Canal tips.
