Surefire EP4 Sonic Defender Plus Ear Plugs

Spending long days on your bike can be exhausting. One of the things that really compounds those affects is a lack of ear protection. We have tried a number of options that are available over the counter and the EP4 Sonic Defender PLUS ear plug is the best option we have found by a good margin. Your hearing health should never be ignored. The EP4 Sonic Defender Plus will protect your hearing against Noise-Induced Hearing Loss (NIHL) without compromising your ability to hear routine sounds or conversations in noisy environments. Their triple-flanged-stem provides a Noise Reduction Rating (NRR) of 24 dB.


  • Provides a 24-dB Noise Reduction Rating (NRR) with filter caps inserted
  • Lowers potentially dangerous noise levels above 85 dB
  • Patented EarLock® retention rings utilize seven contact points to lock earpieces in place and fit the same way every time; soft, double-flanged stems provide secure seals and all-day comfort.
  • Made from hypoallergenic, medical-grade polymer that's soft, durable, and long-lasting.
  • Low-profile design for superior comfort when worn with a mask, helmet or hat, or while using a phone, headphones or supplemental hearing muffs.
  • Available in BLACK

Each set is packaged in a convenient carry case and includes a polymer lanyard.

Note: EP4 earpiece will not provide hearing protection if the noise-reducing filter is removed
