SureFire EP4 Sonic Defenders Plus Filtered Earplugs, Medium

EP4 Sonic Defenders Plus are designed to 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 (NRR) of 24dB. The earplug's proprietary design incorporates a special noise-reducing filter that allows safe sound levels to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced. EP4s include attached filter caps that can be inserted for additional protection and blocking out lower-level noise, such as that heard on a plane, where hearing ambient sounds or conversations isn't critical.

The right and left earpieces are color-coded and made from a soft but durable, hypoallergenic polymer that provides all-day comfort and an extended product life (up to 6+ months, depending on usage and care). Their patented EarLock retention rings lock the earplugs in place, while the soft, adjustable triple-flanged stems provide secure seals in the ear canals. The low-profile design means EP4s can be worn while wearing a helmet or mask, or while using a phone or headset. They are available in clear, black, or orange.

In addition to their noise-reducing capabilities, the comfortable EP4 Sonic Defenders Plus can also serve as earpieces for compatible radio communication systems simply by removing the noise-reducing filter and attaching the earpiece to the system. However, it's important to note that once the noise-reducing filter has been removed, the EP4 earpiece no longer provides hearing protection.

The key features of the EP4 Sonic Defenders Plus include:

• 24dB Noise Reduction Rating (NRR) with filter caps inserted
• Ability to hear safe sound levels (with filter caps out) as if you weren't wearing ear plugs
• Soft, adjustable, triple-flanged stems that provide secure seals in ear canals and all-day comfort
• Low-profile design that allows you to keep them in place while wearing a mask, helmet, hat, or while using supplemental hearing muffs
• Patented EarLock retention rings that utilize seven contact points to lock earpieces in place and fit the same way every time
• Made in the USA from hypoallergenic, medical-grade polymer that is soft, durable, and long-lasting
