The Sordin Supreme MIL AUX SFA utilizes Flexible Attenuation technology to provide adaptable hearing protection in extreme noise environments. This military-grade headset features a modular design with included distance rings and attenuation foam, allowing users to switch between a slim profile at SNR 26 dB and high-protection SNR 32 dB. Designed for professional use, the level-dependent active noise reduction ensures total situational awareness by reproducing safe ambient sounds while instantly suppressing harmful impulse noises like gunshots.
Built to withstand rigorous conditions, the headset is tested to MIL-STD-810G and MIL-STD-810H standards with waterproof IP67 microphones and sealed circuit boards. The fail-safe communication system includes dual speakers in each cup, ensuring radio signals remain audible via the 3.5mm AUX jack even if battery power is lost. Its slim headband is optimized for use under ballistic helmets and can be easily converted to a helmet-mounted configuration. This model provides up to 600 hours of battery life and features a comfortable design suitable for extended operations.
