EP4 - 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.
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.
Sizes are small, medium, and large. Sizing is based on the size of the ear's "concha bowl". Medium EP4 Sonic Defenders Plus fit most people with larger ear canals comfortably. Consult Sizing Chart for proper fit.
For those with normal to smaller-sized ear canals, double-flanged EP3 Sonic Defenders may provide a better fit.
