SureFire EP6 Signature Series Hearing Protection Earpieces were designed to meet the demanding needs, and style demands, of auto racing enthusiasts. That's why they're endorsed by drag-racing guru Rich Christensen. EP6 Signature Series Earpieces by SureFire help protect the hearing of racing fans, pit crews, and anyone else exposed to the potentially dangerous noise levels of auto racing, which can exceed 140 dB (about the same loudness as a gunshot) and can permanently damage hearing, especially with continued exposure. These SureFire Hearing Protection earpieces have a unique design that blocks potentially harmful sound levels while allowing safe levels to still be heard, so you can talk with those around you. Patented Hocks Noise Braker filters prevent potentially harmful noises above 85 dB (like the scream of a high-performance engine) from entering into your ear canal, while safe sound levels below 85 dB are allowed to pass through and be heard. For additional Hearing Protection to block lower-level sounds and noise in quieter situations, such as in an airplane or while sleeping, the attached stoppers can be inserted for a Noise Reduction Rating (NRR) of 16 dB.
SureFire EP6 Signature Series Ear Pieces are made from a soft, hypoallergenic polymer and ergonomically shaped to lock into your ear, providing all-day comfort and a secure fit. The low-profile design means they can be worn under a helmet or hat-even while using a phone. Available in racing black (for flesh-colored alternatives, see the SureFire EP3 Sonic Defender Earpieces or for those with larger ear canals, see SureFire EP4 Sonic Defenders Plus Earpieces).
EP6 Signature Series Ear-Pieces are sold in a single left/right set. Each set is packaged in a convenient carrying case. They come in small (S), medium (M), and large (L). Medium-sized EP6s tend to fit most people.
