EP7 Sonic Defenders Ultra protect users’ hearing from dangerous noise levels—without interfering with their ability to hear ambient sounds and conversations. These affordable, 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.
