OTTO’s NoizeBarrier Micro electronic earplugs offer unsurpassed situational awareness and clear communication while providing hearing protection from loud noises. The dual-mode NoizeBarrierTMMicro earplugs offer active hearing protection as well as hearing enhancement for extremely effective sound localization and detection.

The noise-isolating eartips combined with proprietary sound processing electronics produces an earplug that responds to your environment.
In standard mode the ear plugs provide active situational awareness when sound levels are safe. The earplugs provide a higher level of hearing protection (up to 15 dB) when there is sustained loud noise.

With a simple press on the touch pad, the user activates enhanced hearing mode which provides 5X amplification of soft sounds.

In either standard or enhanced hearing mode the earplugs provide maximum protection (up to 40 dB) from loud impulse noises.
