Highly effective, ultra-comfortable, and reusable EP10 Sonic Defenders® Ultra Max earplugs provide the highest level of hearing protection of any earplugs made by SureFire—an extraordinary Noise Reduction Rating (NRR) of 30dB! These “full-block” earplugs feature soft memory-foam Comply™ Canal Tips that seal in the ear canal, blocking out potentially harmful noises and providing all-day comfort. They are an excellent choice for industrial, tactical, recreational, and everyday applications where maximum protection against continual noise levels is desired and the ability to hear ambient sounds or conversations is not a priority.* 

Along with soft memory-foam tips that expand in the ear canal for a near-custom fit, EP10s feature SureFire’s patented EarLock® retention rings, which “lock” the earplugs in place for a secure fit and hold that are unparalleled. And their smart low-profile design means they can be worn while wearing a mask, helmet, or even supplemental hearing muffs. Sonic Defenders Ultra Maxare constructed of a soft, hypoallergenic medical-grade polymer that is comfortable enough to be worn all day and durable enough to provide an extended service life of six months or more, depending on usage and care. 

EP10 Sonic Defenders Ultra Max come in three colors—black, orange, and clear—and are available as a single left/right set or in a box containing 25 individually polymer-bagged sets. Each set comes with an extra set of Comply™ Canal Tips (replacement tips are also available for purchase under the Parts and Accessories section of this page) as well as an attachable/detachable polymer lanyard and a convenient carrying case. EP10s are available in small (S), medium (M), and large (L) sizes, with proper sizing based on the dimensions of your ear’s concha bowl. Size “medium” fits most people.

For affordable, non-electronic hearing protection that’s re-usable and provides maximum protection, comfort, and retention, there’s no beating EP10 Sonic Defenders Ultra Max earplugs by SureFire. 

*For hearing protection featuring Comply™ Canal Tips and the ability to hear safe-level sounds and conversations, use filtered foam-tipped EP7 Sonic Defenders® Ultra.
