The Sordin Supreme™ MIL AUX SFA™, based on the new Sordin Flexible Attenuation™ (SFA™) concept, is developed with the user and ever-changing conditions in mind. At SNR 32 dB, it safely protects your hearing even in extreme noise environments, while providing instant interchangeability for a slimmer cup design – enabling optimization for different operating environments or helmet compatibility needs. Our mission is your successful mission!

Features of Sordin Supreme MIL AUX SFA NEW – 32dB

  • Extra attenuation foam and increased cup volume (with distance ring) for higher passive attenuation
  • Easy to use push buttons operate the electronic functions
  • Level dependent function that allows the user to hear ambient sound, such as warning signals, moving vehicles and important information and still be protected from hazardous noise
  • Available with black, green or sand cups
  • The electronic circuits are encapsulated in multiple layers of lacquer and polymer for increased robustness
  • Amplification of low sounds
  • Very natural sound reproduction through the speakers inside the cups
  • Two loudspeakers in each cup, one for surround hearing and one for radio/communication - radio/communication works even when batteries are out
  • Water proof microphones (IP67 tested)
  • Sound reproduced through the level dependent function is limited to a maximum of 82 dB
  • Automatic switch-off after 4 hours, if no button is activated, saves battery life
  • Audio input (AUX) for connecting external audio sources
  • Low battery warning when approximately 40 hours left of the battery life


The Sordin SupremeTM MIL AUX SFATM models have been tested against relevant parts of the standards MIL-STD-810G and MIL-STD-810H.
