Features & Specifications
- Incorporates a streamlined design for optimal comfort, and true 3D hearing technology for hearing protection and improved situational awareness.
- Available with optional NFMI earplugs which offer wire-free double hearing protection capability – specify when ordering.
- Attaches to the rear portion of Ops-Core Accessory Rail Connectors (ARCs) leaving the top portion of the ARCs free for mounting lights, cameras, and other helmet components for optimal system level performance.
- Rotates back to the rear of the helmet when not in use, creating a very low profile—ear cups not visible from front view when stowed.
- Streamlined design also provides freedom of movement and unobstructed head range of motion. Restores “natural hearing” with the outside environment for improved situational awareness while also providing robust hearing protection.
- Single-point gimbal attachment allows for 360° of adjustment instead of conventional adjustment systems–auto positioning to each individual’s ear/head shape.
- High performance ear cushions ergonomically fit the head geometry, providing a better seal and increased noise attenuation.

- Compatible with the Ops-Core FAST and Sentry Helmet Systems.
