Telex Air 3100

Full-cushion aviation headset with amplified, noise-canceling electret microphone(s)

The Telex Air3100 is a medium-weight noise-reduction headset with amplified, noise-canceling, electret microphones. It has a noise reduction rating of 21 dB, and are suitable for use in moderately noisy aircraft. All models feature a unique headband design that distributes ear cushion pressure evenly over the entire ear with no pressure points, unlike conventional designs which apply more pressure on the bottom of the ear than on the top. An added advantage of this design is that the headset folds into an extremely compact shape for storage. The Air3100 headset is approved for aircraft use under FAA TSO’s C57a and C58a.

Comfort & Fit
The Air 3100 features a comfortable foam-filled headband pad and ear cushions. The headband pad evenly distributes the headset weight without pressure points for maximum wearer comfort. The ear cushions combine comfort and light weight with an excellent acoustic seal. An outer urethane layer ensures long life and gel-filled ear cushions are also available.

The boom arm features a sealed ball-and-socket joint and flexible boom for precise microphone placement on any head size. The boom rotates overhead for microphone placement on either side of the head. The microphone cartridge features a noise-cancelling electret element; the cartridge snaps on and off easily for replacement. The microphone amplifier, which is housed in the microphone cartridge, is adjustable through an opening in the microphone assembly.

The microphone cartridge is protected inside the boom arm. Shielded wire throughout the headset protects against RFI and EMI. Strain-reliefs on all cords provide maximum durability.

The Air 3100 features a unique design that allows it to fold into an extremely compact shape for storage and transport.
