OTTO

In The Ear Headsets

OTTO's in-the-ear headsets are built for tactical situations with SureFire® patented noise-reducing earpieces and specialized NoisEz™ eartips. The Hurricane II™ offers OTTO's highest NRR at 29 dB while fitting well under most helmets and hard hats. The H3™, with SureFire® patented EarLock retention rings, is a lightweight, low-profile headset that keeps situational awareness open while dampening loud noises — up to 40 dB NRR when the SureFire® filter switch is closed.
