Surefire EP3 Sonic Defenders

$13.00 - $293.00
SKU: EP3-MPR//Out of Stock


Sonic Defenders™ protect your hearing without interfering with your ability to hear routine sounds and conversation. Safe sound levels pass through while potentially harmful noises are lowered.

Sonic Defenders are made from an ultra-soft, hypoallergenic material and ergonomically shaped so you can wear them comfortably throughout the day. Their low-profile design means you won't have to remove them while wearing a helmet, mask, or hat; or before using the phone, a headset, or supplemental ear muffs.

The sizes (small, medium and large) refer only to the outer earpieces that fit in the ear's concha bowl and help hold the EP3 in place. Proper EP3 size is based on the dimensions of your ear's concha bowl. Medium fits most people.

Small - Concha bowl height less than 1"
Medium - Concha bowl height 1"
Large - Concha bowl height greater than 1"

"I have a pair of EP3s that I need to replace (they have lasted a very long time but I think it's time for a new pair). How can I tell what size they are? It has both a M and an L embossed on it."

Check the other one. I would bet they are medium. They should both have an ""M"". One should have an ""R"" for right and the other should have an ""L"" for left.

"What is the NRR for this hearing protection?"

The NRR for the EP3 is 24db
