EP7 Sonic Defenders Ultra are earplugs designed to protect your hearing while still allowing you to hear routine sounds and conversations. They have a foam-tipped stem design with soft memory-foam Comply™ Canal Tips that fit most people. These earplugs have a Noise Reduction Rating (NRR) of 28dB and a proprietary design that incorporates a special noise-reducing filter to reduce potentially harmful noises above 85dB. The filter caps attached to the EP7s can be inserted for additional protection and to block out lower-level noise, such as that heard on a plane. They are available in clear, black, or orange, and come with a 26" polymer lanyard and an additional pair of Comply™ Canal tips.

The Sonic Defenders Ultra earplugs utilize a patented EarLock® retention ring that locks the earpieces in place and ensures they fit the same way every time. The earplugs are made from a hypoallergenic, medical-grade polymer that's soft, comfortable, and durable. They have a low-profile design, which means they can be worn while wearing a helmet or mask, or while using a phone or headset.

Additionally, these earplugs can serve as earpieces for compatible* radio communication systems by removing the noise-reducing filter and attaching the earpiece to the system. It's crucial to note that if the noise-reducing filter is removed, the EP7 earpiece will not provide hearing protection.
