The Liberator II BTH Tactical Headset offers integrated two-way communication, sound-attenuation and user comfort. Originally designed for military Special Forces, the Liberator II BTH provides a new Behind-the-Head suspension system for exceptional comfort and digital sound processing for accurate replication of ambient sound. Progressive audio-compression technology supports hearing safety. Unlike other sound-attenuating headsets, the Liberator II BTH enhances the user's situational awareness by accurately replicating the audio properties, direction and magnitude of ambient sound sources in the headset. Available in many configurations and for most radio makes and models.
