SureFire Sonic EP4 Defenders Ear Plugs protect your hearing without interfering with your ability to hear routine sounds or conversations. The double-flange-stem design fits most people and provides a Noise Reduction Rating (NRR) of 24dB. Sounds are allowed to pass through into the ear canal at safe levels,while potentially harmful noises (above 85dB) are reduced through a proprietary design that incorporates Hocks Noise Braker filter. EP4s include attached stopper plugs, which can be inserted for further protection and blocking out lower-level noise, like that heard on a plane. The right/left color-coded Sonic Defenders are made from a soft durable, hypoallergenic polymer and are ergonomically shaped, with an adjustable stem design, providing a fit for all-day comfort. The low-profile design means they can be worn while wearing a helmet or mask, or while using a phone or headset.
Proper size is based on the dimensions of your ear's concha bowl. Size medium fits most people. Each set is packaged in a convenient carry case and includes a polymer lanyard.
