SureFire Sonic Defenders® Plus EP4 help protect your hearing from harmful noise levels without interfering with the hearing of routine sounds or conversations. Potentially dangerous noises (above 80 dB) can't pass through their filters, while safe sound levels easily pass through. If you're in a situation where you want to block out lower level noise, such as in an airplane or while sleeping, simply insert the attached stopper plugs. SureFire Sonic Defenders Plus hearing protectors are designed to stay in place all day; and their ergonomic shape ensures all day comfort.
