- Headset model: The adapters are stated for Comtac I/II headsets. Confirm that your headset matches that format.

Setup and Correct Use
The adapters attach to both sides of the helmet and the headset earmuffs clip into the buckle. The headset wires are then routed and secured to the upper part of the helmet. Once fitted, the earmuffs can rotate freely.
For a correct setup, remove the cloth covers from both sides of the headset and unwrap the hoop around the headband before attaching the adapters.
Before You Decide
Confirm that your helmet has side arc rails and that your headset is Comtac I/II before choosing this pair of adapters. If you need a different rail shape or a different headset fit, check another version instead. Follow the manufacturer’s instructions for fitting and use.
