EP4 Sonic Defenders® Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flange 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 the patented Hocks Noise Braker® filter. EP4s include attached stopper plugs which can be inserted for further protection and they also block out lower-level noise like that heard on a plane. They can be used in situations 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 (3 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 or black.
