Ear-simulator 3D Hear-Through preserves natural spatial awareness — locate threats by direction and distance, not just volume. Connectorized version uses quick-release Fischer connectors so you can swap downlead cables for different radios without changing headsets. Hearing Protection Configuration NRR SNR Headset Only 22 dB 27 dB With NFMI Earplugs 34 dB 41 dB Weight Configuration Weight Headband 0.85 lbs (386g) Rail Mounted 0.94 lbs (426g) NFMI Headband 0.92 lbs (419g) NFMI Rail Mounted 1.01 lbs (460g) All weights include batteries (2× AAA Lithium). Key Features 3D Hear-Through (3DHT): Patented Ear-Simulator design (U.S. Patent 12,323,119) reproduces ambient sounds through the earcups with true directional accuracy — eight scalable volume levels up to +12 dB (Super-Normal Hearing). Press-and-hold any volume button to activate; press both buttons to deactivate. NFMI Double Protection: Optional Near Field Magnetic Induction earplugs sit inside the earcups for double hearing protection — NRR jumps from 22 dB to 34 dB. No wires, no batteries, no charging. Toggle between earplug and standard audio with the mode-switch button on the left earcup. Fail-Safe Communications: If batteries die, a hardware-level Bypass Activation Transistor physically reroutes the signal path around the digital processor — radio audio and transmit continue uninterrupted. 3DHT also auto-hibernates after 2 hours of inactivity to preserve battery life; pressing any volume button wakes it. Quick-Release Fischer Connectors: Set up a downlead on the left, right, or both sides — swap radios or reconfigure single/dual channel without changing headsets. Triangle alignment mark ensures correct mating. Pull the outer sleeve to disconnect (never pull the cable). Noise-Cancelling Boom Mic: Ambidextrous 150 Ω dynamic boom mic mounts to either earcup with a thumbscrew. Mitigates background noise in high-noise environments. Remove entirely for listen-only or hear-through-only operation. U-173/U Accessory Port: Integrated microphone mounting point accepts any standard U-173/U plug — commonly used for mask mics on respirators like the Ops-Core SOTR. Mission Configurable: Switch between headband and helmet-rail mounting. Nylon-covered wire-frame headband designed to be worn under a helmet. Earcups quick-attach/detach from either platform. Radio Compatibility Requires a downlead cable (sold separately) matched to your PTT/radio: AN/PRC-117F, AN/PRC-148, AN/PRC-148C, AN/PRC-152, AN/PRC-163, Motorola APX/XTS/HT750, Persistent Systems MPU5, and more.
