The OTTO NoizeBarrier Micros are a low-profile, easily transportable ear protection solution with up to 40 dB of impulse protection and 15dB of adaptive noise attenuation. The earplugs themselves last up to 16 hours on a single charge, and the included charging case can replenish that charge up to 20 times, eliminating the need for bulky spare batteries or extra chargers.
For maximum protection, we recommend pairing these earplugs with over-ear protection at indoor ranges or in other enclosed spaces.
