NATO wired with TP-120 Nexus connector. Made in USA. NoizeBarrier® Technology 🔊Dual-Coil Speakers — Proprietary NoizeBarrier® technology automatically adapts loud or impulse sounds to a safe level while preserving normal conversation and radio audio without clipping or shutdown. 🎯360° Situational Awareness — Microphones built into each earcup provide accurate sound localization to detect the direction of potential threats with near certainty. 🎤Noise-Canceling Boom Mic — Built-in active wind and noise reduction virtually eliminates background noise for clear radio transmissions in loud environments. Configurable left or right. 📻Single & Dual Comm — Single comm variants route radio audio to both ears. Dual comm supports two radios simultaneously with selectable signal separation (left, right, or both ears). 🔇23 dB NRR / 29 dB SNR — Outstanding hearing protection. Impulse noises are reduced to a safe 85 dB level with no clipping or shutdown of situational awareness. 🔋Up to 100 Hours — Powered by 2× AAA batteries (lithium ion recommended). Auto idle shutdown after 2 hours will not degrade with depleting batteries. Design & Modularity ⚙️Fully Modular Platform — Field-changeable between headband and helmet mount configurations without tools. Compatible with Ops-Core ARC/FAST, Team Wendy, and M-LOK/MTEK rail systems via optional mount kits. 🪖Low-Profile Earcups — Reduced cup size fits under ACH, IHPS, and other mid/full-cut helmets. Over 12% lighter than previous models. Will not interfere with shouldering a firearm. 🔌NATO Wired — TP-120 Nexus — Standard NATO/military wiring compatible with DISCO32 Constant Able and other NATO PTTs. Quick-disconnect cable options available for rapid field swaps. 👂Comply™ Foam Ear Cushions — Ultra-soft foam forms a tight acoustic seal. Snap-off design for easy field replacement. Optional gel ear cushion upgrade available.
