Features and Benefits:
- 19dB* Noise Reduction Rating (NRR) for EP4 Sonic Defenders Plus
- Lowers potentially dangerous noise levels above 85dB
- Ergonomic design and triple-flange stem design conforms to ear shape for comfort and secure retention
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 19dB. Sounds, at safe levels, are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are greatly reduced via a proprietary design that incorporates the patented Hocks Noise Braker® filter. EP4s include attached stopper plugs, which can be inserted to block out lower-level noise like that heard on a plane, or in situations where hearing ambient sound or conversations isn't critical, such as when trying to sleep. 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.
