The Telex Air 3500 Headset is a passive noise attenuating headset that demonstrates Telex’s commitment to provide the maximum possible hearing protection in noisy aircraft cockpits. The boom and earcup mountings are used as the cord entrances to minimize the number of openings in the earcups. The size and shape of the earcups are optimized for broad-spectrum noise reduction. Three quick-set headset pressure settings let the user select the comfort/noise attenuation setting based on the amount of aircraft noise and personal comfort requirements. Dual-eccentric tension adjustment knobs allow the user to quickly and easily dial in the desired setting.Unlike some other headset designs, the microphone boom on the Air 3500 mounts to the bottom of the earcup rather than to the side. This assures unobstructed peripheral vision. In addition, the microphone boom and microphone assembly may be worn on either side of the head. Users are able to control the volume in each ear with the separate volume controls for each ear.Cadmium-bronze wire and tapered strain reliefs ensure long cord life. Polypropylene insulation over wires and urethane jacket for maximum durability. Shielded wire is used throughout for RFI and EMI protection.
