The Telex Air3500™ weighs 13.6 ounces and has a 25-decibel noise-reduction capability. A unique three-position tension adjustments lets the wearer quickly change the headset from low tension to high tension, providing the desired level of noise protection and a custom fit. The unit comes with foam and gel ear seals, and the plastic headband is reinforced with stainless steel at the stress points for maximum durability and light weight. Ear- cup volume, cushion design, and a single assembly for the microphone boom and cord also keep unwanted noise to a minimum. The flexible boom is designed to stay out of the pilot's peripheral vision, and the replaceable noise canceling electret microphone can be reversed and worn on either side of the head. The headset also features a stereo/mono switch and dual volume controls.
