The Surefire EP4 Sonic Defenders Plus Filtered Flanged Earplugs are a highly protective tool for protecting your hearing on the job or in other situations where exposure to noise is a concern. The great thing about these ear plugs is that they protect your hearing without interfering with your ability to hear everyday sounds or conversations.

These noise-reducing ear plugs work so well because they are designed with a triple-flanged stem that fits larger ear canals. They also provide a Noise Reduction Rating (NRR) of 24dB. This means sounds that are heard at safe levels are permitted to pass into the ear canal while potentially harmful sounds (above 85dB) are reduced via a proprietary noise-reducing filter. The EP4 Sonic Defender ear plugs come with attached filter caps, which can be inserted into the ear for additional noise protection and blocking out lower-level sounds, such as airplane noise where it is not that important that you hear ambient noise or conversations, for example.

These protective ear plugs are color-coded right and left so you always keep them organized and in the right ear. They are made of soft yet durable, hypoallergenic polymer that delivers all-day comfort. The extended product life (up to six or more months, depending on usage and care) is another value-added feature of these ear plugs.

The patented EarLock retention rings on these ear plugs lock them in place, while the soft, completely adjustable triple-flanged stems securely seal the plugs into the ear canal. The design is low profile, too, meaning these ear plugs fit nicely underneath a helmet or mask or while using a phone, mobile or even a headset. The earplugs come in clear, black, or orange.

Communications-compatible: The EP4 Sonic Defenders Plus also serve as earpieces for radio communication systems* that are compatible. Simply remove the noise-reducing filter and attach the earpiece to the system. NOTE: The EP4 earpiece does not provide hearing protection once the noise-reducing filter has been removed from the ear.

Size: EP4 ear plugs are available in small (S), medium (M), and large (L) and are based on the size and dimensions of the concha bowl inside your ear (see graphic). Medium will fit most people.

Quantity: EP4 Sonic Defenders Plus can be purchased as a single left and right pair or in a box of 25. Each set comes in a convenient carry case with a polymer lanyard.
