EP4 Sonic Defenders® Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. The triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating of 24dB. Sounds considered safe (below 85dB) are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced via a special noise-reducing filter.
EP4s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise when 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. 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.
Comfortable EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems* simply by removing the noise-reducing filter and attaching the earpiece to the system. Please Note: EP4 earpiece no longer provides hearing protection once the noise-reducing filter has been removed. Available in Clear Small or Black Medium.
Each set is packaged in a convenient carry case and includes a polymer lanyard.
