This package includes everything you need to protect your hearing, communicate with those nearby, and easily mount your headset to your arc rail equipped helmet. The 3M™ PELTOR™ ComTac™ V Headset is a reliable, rugged solution you can count on. This headset has omni-directional microphones and high-fidelity speakers that are optimized to transmit voice communication and can pick up sounds with great sensitivity. With an excellent signal-to-noise ratio for clear and accurate sound replication, the result is a more natural-sounding headset with unmatched sound clarity. The Defender series is for those that do not need radio communication capability but still desire all of the positive aspects of ComTac™ headsets. The Peltor Arc Rail Adapters allow users to mount ComTac™ headsets to any reverse dovetail style accessory rail, such as those found on Ops Core and Team Wendy EPIC helmets. The Peltor Arc Rail Adapters replace the headband of the headset but can easily be removed if the user desires to revert back to the headband mounting system. Increase comfort and easily transition the headset from the stowed and unstowed positions with the adapter’s intuitive design.
