MARK™ provides seamless integration of electronic hearing protection/communication headsets with headborne systems. The MARK™ for 3M™ Peltor™-style Headsets specifically adapts 3M™ Peltor™ ear cups and similar styles. MSA/Sordin® with SARA™ system sold separately. MARK™ comes with all hardware for Ops-Core® ARC rails (and similar), Team Wendy® EXFIL® rail systems or Busch Protective® rail systems. M-LOK® adapters sold separately.

Designed to reduce the overall profile of mounted communication headsets and improve the seal of the ear protection, MARK™ is the lowest profile headset helmet mount on the market. Rather than using a traditional pop-in/pop-out mechanism, MARK™ allows the ear cups to be pulled away from the ears and rotated backwards for stowage. Given the variance in head shapes and sizes, eliminating the pop-in/pop-out mechanism yields a tighter seal for the ear cups, resulting in a higher Noise Reduction Rating (NRR). MARK™ is compatible with most major helmet rail types for attachment of many popular electronic hearing protection.
