EP7 Sonic Defenders UltraEP7 Sonic Defenders Ultra protect your hearing from dangerous noise levels—without interfering with your ability to hear ambient sounds and conversations. These non-electronic earplugs feature Hocks Noise Braker® filters that allow lower-decibel sounds to pass through, while potentially harmful sound levels above 85dB are reduced to safer levels.

For situations where you want to block out lower-level noise, EP7s feature attached stopper plugs that can be closed to provide an impressive Noise Reduction Rating (NRR) of 28dB. Soft-polymer construction and Comply™ Canal Tips made of soft memory foam provide all-day comfort, while the patented EarLock™ by SureFire®  design contributes to unparalleled retention. And their low profile means reusable Sonic Defenders Ultra can be worn under headphones, helmets, or masks—even while using the phone.
