SureFire EP4 Sonic Defenders Plus


What’s Included | Specs | Pictures | FAQ | Restrictions | Related Info

If you’re looking for minimalist, comfortable, in-ear protection, the SureFire EP4s are a good option. They offer a 24-dB noise reduction rating when the filter caps are inserted. The filter cap can be opened to allow for clearer sound without having to remove the unit from your ear. The tips are silicone, so they’re comfortable and provide an adequate seal. The shape of the EarLock retention rings serves to hold the units in place, preventing them from accidentally falling out of your ear.

The EP4’s include a carrying case, which is nice for keeping them organized in your range bag or kit, and they also make for a great set of backup ear protection, since they work well, they’re inexpensive, and they take up little to no space. If you’re looking for memory foam tips, check out the SureFire EP7 Sonic Defenders.

We recommend using any in-ear hearing protection in conjunction with over-ear hearing protection.

  • Low-profile design for superior comfort when worn with a mask, helmet or hat, or while using a phone, headphones or supplemental hearing muffs.
  • Protects against Noise-Induced Hearing Loss (NIHL) without compromising the ability to hear routine sounds or conversations in noisy environments.

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