SureFire 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. These earplugs are sold in a box containing 25 sets and come in clear color at the large size. Their foam-tipped stem design features soft memory-foam Comply™ Canal Tips and provides a Noise Reduction Rating (NRR) of 28 dB. Sizing is based on the dimensions of your ear’s concha bowl.
Sounds at safe levels are allowed to pass through into the ear canal, while potentially harmful noises (above 85 dB) are reduced via a proprietary design that incorporates a special noise-reducing filter. The EP7s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, in situations where hearing ambient sounds or conversations isn’t critical. The Sonic Defenders Ultra also serve as earpieces for compatible radio communication systems by removing the noise-reducing filter and attaching the earpiece to the system, though the EP7 earpiece will not provide hearing protection if the noise-reducing filter is removed.
Right/left color-coded Sonic Defenders Ultra are made from a soft but durable, hypoallergenic polymer that provides all-day comfort and an extended product life (up to 6+ months, depending on usage and care). Their patented EarLock retention rings lock the earplugs in place, while soft foam-tipped stems provide secure seals in the ear canals. Their low-profile design means they can be worn while wearing a helmet or mask, or while using a phone or headset.
