The Sordin T2 Neckband Black Cups Hearing Protector represents the absolute pinnacle of MIL-rated tactical audio engineering, meticulously configured with an ultra-low-profile neckband design optimized for direct integration beneath ballistic helmets and heavy headwear. Operating on a highly efficient, single-battery architecture compatible with standard AA or 14500 Li-Ion cells, this active electronic headset offers multi-layered waterproof protection submersion-tested down to two full meters. Shooters can seamlessly switch between four specialized audio profiles—Tactical, Comfort, Dual, and Ambience—to optimize high-fidelity situational awareness and directional sound localization on dynamic firing lines. Designed on the modular SordinFLEX platform, it features a rugged rear stabilizing band paired with premium memory foam ear cushions that ensure a pressure-free, acoustic seal around protective eyewear. Fail-safe redundant internal speakers ensure uninterrupted radio comms remain fully operational through its dual AUX inputs even if your primary battery drains completely out.
