Product Overview

EP4 Sonic Defenders Plus - SMALL, MEDIUM, & LARGE Sizes

The Earpro EP4 Sonic Defenders Plus Ear Plugs by Surefire are the perfect hearing protection for avid shooters who want something low profile and easy to wear or for operating heavy equipment.

Sonic Defenders Plus are meant to be used in noisy environments, where the Hocks Noice Brakers block potentially dangerous noise levels (Above 85dB). However, safe sounds can pass through to the ear canal (Below 85 dB). With a triple flanged design these will fit in almost any ear canal, big or small. Surefire makes high quality HEARING PROTECTION and Ear Plugs that work well for shooting, auto racing and car racing, working with heavy equipment, and mowing the lawn around the house. With 24 decibels (Scale 0 to 30) of noise reduction, the SONIC DEFENDERS PLUS are the obvious solution for loud environments. These ear pieces come in 3 different sizes Small, Medium, and Large which refer to the size of the Helix Bowl or Concha Bowl as shown in the pictures and video and are available in Natural or Black Color. The low profile design makes them easy to wear with a hat, helmet, or glasses and can easily be used with a cell phone or headet.

    Outstanding product. I bought these to wear while I ride my motorcycle and have never had a problem with them. They keep out the wind and I keep the hole open to still be able to hear my stereo. Highly recommend.

    Great product, despite reading reviews stating otherwise. Speaking for myself, can clearly hear conversation while shooting, they're comfortable, adjustable, and cheaper than Surefire's website. Fast shipping.
