OTTO V4-11072 NoizeBarrier Range SA Active Hearing Protection Headset

The OTTO NoizeBarrier Range SA is a premier American-made active hearing protection headset originally designed for military use and now trusted by law enforcement, special operations, range officers, and serious firearm professionals worldwide.

Key Features:

• NRR 23 dB / SNR 29 dB Hearing Protection - Industry-leading noise reduction performance against gunfire, impulse blasts, and continuous high-decibel environments common at indoor and outdoor ranges, shoot houses, and tactical training facilities
• 4-Millisecond Impulse Response Time - One of the fastest noise-suppression refresh rates on the market (compared to 28 ms on most competing electronic earmuffs), instantly attenuating muzzle blasts to safe levels without clipping out the surrounding soundscape
• 360-Degree Situational Awareness - Microphones built into each ear cup are angled to mirror the human ear canal, amplifying low-level sounds, footsteps, voices, and range commands while enabling precise sound localization and direction-of-fire identification
• No-Clip Active Volume Technology - Automatically reduces extra-loud sounds to a safe decibel level without complete shutdown, so you continue to hear range commands, teammates, and environmental cues even during continuous fire
• 5-Level Volume Adjustment - Easy-access controls mounted on the left ear cup allow precise gain adjustment with gloved hands or under stress
• Reduced Cup Profile - Slimmer cup geometry fits comfortably under Advanced Combat Helmets (ACH), IHPS helmets, and most mid-cut and full-cut tactical helmet systems without breaking the ear seal
• Comply Foam Ear Cushions - Ultra-soft, hypoallergenic foam cushions form a tight, comfortable seal that conforms to the head and pairs cleanly with safety glasses, ballistic eyewear, and shooting glasses without breaking acoustic protection
• Snap-On Field-Replaceable Ear Seals - Cushions snap off and on in seconds for fast field replacement, hygienic cleaning, and extended headset service life
• Optimized for Firearm Use - Ear cup shape engineered to allow smooth, unobstructed shouldering of long guns from either shoulder
• IP68 Rated Construction - Sealed against dust intrusion and water immersion for reliable performance in rain, mud, dust, and harsh field conditions
• 75+ Hours Runtime on 2 AAA Batteries - Standard alkaline AAA batteries deliver days of continuous use; auto-shutoff feature preserves battery life
• Optional Comms Compatible - Configurable to interface with remote speaker mics and surveillance kits using the optional V3-1074 cable (sold separately) for discreet tactical communications
