The Liberator HP headset is the next generation in electronic hearing protection, offering crisp, clear audio in a durable, scratch-resistant, slim earcup. The Liberator HP provides enhanced hearing protection in all environments, including those with impulse/gunfire noise and high-decibel, constant background audio. The wearer is protected while advanced sound localization allows for maximum situational awareness and sound detection. The glass polymer, injection-molded, slim earcups provide excellent durability and is the base earcup for the Liberator IV and V headsets. The Liberator HP can be sent in and converted (for an additional charge) into either a single or dual comm headset. Once the headset has been converted to a Liberator IV or V, a Push-to-Talk (PTT) can also be purchased separately and added to the system. This product is ANSI Certified but does not yet have CE Certification for our European customers. It is recommended to remove the batteries when storing the headset or when the headset is not in use.
