The noise-isolating eartips combined with proprietary sound processing electronics produces an earplug that responds to your environment. The earplugs provide normal situational awareness when sound levels are safe, a higher level of protection (up to 15 dB) when there is sustained loud noise, and maximum protection (up to 40 dB) from loud impulse noises.
With a simple press on the touch pad, the enhanced hearing mode provides 5X amplification of soft sounds, while maintaining the impulse noise protection. NoizeBarrier™ earplugs can be worn all day without the need to remove them to hear.
The earplugs have up to 16 hours of battery life and come with a rugged, waterproof case for earplug storage and charging.
