Active Tactical Headphones Earmor M31

Earmor M31H Active Headphones: dual microphones, NRR 22 and helmet mount

The Earmor M31H housing is made of 3 mm polycarbonate, and the kit includes mounting brackets for Ops-Core FAST ARC, Team Wendy EXFIL and MTEK Mlok helmets. These are active headphones with a noise cancellation circuit: they amplify quiet ambient sounds and suppress sharp noise above 82 dB, including gunshots. The olive-green housing with black details, ear cups, headband and built-in microphones are visible in the product photos.

Who needs these headphones and in what situations?

The model is designed for military personnel, police officers, hunters and pilots—those who need to hear their surroundings while protecting their hearing. As tactical headphones, they work well with helmets: the cups can be rotated and positioned behind the helmet. For shooting practice, these are shooting headphones that pass through speech and quiet sounds while blocking hearing from loud gunshots.
