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.

    A must-have for your hunting pack

    Posted by BDart on Feb 24th 2020

    The Otto Noizebarrier Micros are hands down, the best earplugs I have ever used. The comfort, protection, convenience, and battery life are just a few of the things that set these above the rest. I have used these on six 4-day hunts over 2 month, have not charged the case at all, and it is still reading 70% battery life! Simple to use, push the button to turn on, and insert into ear, then forget they are there. They operate independent of each other, so you can determine which direction sounds are actually coming from. Noise canceling is instantaneous, then immediately switches back to normal hearing.
