Cobra is a modular boom arm headset from TV Equipment which provides the user with personal choice and the flexibility to reconfigure the equipment to suit a specific type of mission. No tools are required and configuration changes can be made in a matter of seconds. The headset has both the boom mic and earphone mounted on flexible arms, which are fully adjustable. The close-coupled supra aural type earphone stands off from the wearer's ear, which provides comfort and, as the ear is not covered, monitoring of ambient noise is maximized. The boom mic can be positioned for best noise cancellation, and system components are fully ruggedized to withstand extreme environments.
