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

The noise-isolating ear tips 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.

    Otto Noizebarrier

    By far and away, the best sound control yet. Even when up loud, the report from firearms is way down. I use the foam inserts as they are the most comfortable. The other options require me jamming them and then digging out. Anyway, I would purchase these again, no question.

    Otto High Def Ear Plugs

    I tried muffs and standard plugs and the Otto's were money well spent. They give me unhindered freedom of movement at high power shooting matches. My scores reflect this. Botach got them to me in two days, as requested. Great service and better product.

    These work great. About 4 hours on shooting my Magnum & no ringing ears. Could hear normally & batteries only used 20-30%.
