EP4 Sonic Defenders Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating (NRR) of 24dB. Sounds, at safe levels, are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced via a proprietary design that incorporates a special noise-reducing filter. EP4s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical. Right/left color-coded Sonic Defenders Plus 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, adjustable triple-flanged stems provide secure seals in the ear canals. A low-profile design means EP4s can be worn while wearing a helmet or mask, or while using a phone or headset. Available in clear, black, or orange.24dB Noise Reduction Rating (NRR) with filter caps insertedLowers potentially dangerous noise levels above 85dBHear safe sound levels (with filter caps out) as if you weren't wearing ear plugsPatented EarLock retention rings utilize seven contact points to lock earpieces in place and fit the same way every time soft, triple-flanged stems provide secure seals and all-day comfortMade from hypoallergenic, medical-grade polymer that's soft, durable, and long-lastingCalifornia Residents Prop 65 warning: Products may contain a chemical known to the State of California to cause cancer, birth defects or other reproductive harm.This product has a manufacturer warranty against defects in materials and workmanship for a period of ONE (1) YEAR from the date of original retail purchase.
