SureFire EP4 Sonic Defenders Plus Filtered Flanged Ear Plug - 1 Pair

EP4 Sonic Defenders® Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating of 24dB. 

EP4s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical. The right / left color-coded Sonic Defenders are made from a soft but durable, hypoallergenic polymer that provides all-day comfort and an extended product life (up to six-plus months, depending on usage and care). Their patented EarLock® retention rings lock the earplugs in place, while adjustable triple-flanged stems provide secure seals in the ear canals.

  • Soft, durable, and long-lasting hypoallergenic, medical-grade polymer construction
  • Low-profile design allows you to keep them in place while wearing a mask, helmet, hat, or while using phone, headphones, or supplemental hearing muffs
  • Lowers potentially dangerous noise levels above 85dB
  • Hear safe sound levels (with filter caps out) as if you weren't wearing ear plugs
  • EarLock® retention rings utilize seven contact points to lock earpieces in place and fit the same way every time
  • Soft, triple-flanged stems provide secure seals and all-day comfort
  • Serve as earpieces for compatible* radio communication systems
  • Detachable 26" polymer lanyard included
  • Color: Black
