EP4 Sonic Defenders^® Plus - Filtered Flanged Earplugs

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 to safe levels 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. The right/left color-coded Sonic Defenders Plus are made from a soft but durable hypoallergenic polymer and are ergonomically shaped with an adjustable-stem design providing a secure fit all-day comfort and extended product life (up to 6+ months depending on usage and care). And their low-profile design means they 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 noise-reducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer provides hearing protection once the noise-reducing filter has been removed.

EP4s are available in small (S) medium (M) and large (L). Proper size is based on the dimensions of your ear s concha bowl. Size medium fits most people. For those with smaller (in diameter) ear canals the two-flange stem of our EP3 Sonic Defenders may provide a better fit than the EP4 s three-flange stem.

EP4 Sonic Defenders Plus are sold as a single left/right set or in a box containing 25 sets. Each set is packaged in a convenient carry case and includes a polymer lanyard.
