Description
EP4 Sonic Defenders Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their tripleflanged 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 noisereducing filter. EP4s include attached filter caps, which can be inserted for additional protection and blocking out lowerlevel noise, like that heard on a plane, where hearing ambient sounds or conversations isnt critical. Right/left colorcoded Sonic Defenders Plus are made from a soft but durable, hypoallergenic polymer that provides allday 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 tripleflanged stems provide secure seals in the ear canals. A lowprofile 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. Comfortable EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems simply by removing the noisereducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer provides hearing protection once the noisereducing filter has been removed.
