Lightweight Headsets
Headset for aircraft Intercom and Radio Systems
The Lightweight Headsets series was developed for use in the cockpit and is part of the onboard communication and radio system. The 91-23 series is certified to ETSO C57a & C58a (equivalent to ETSO C139a) and is used in the Airbus A350.
The headset features a microphone boom with a flexible tube that houses a noise-canceling electret microphone with a built-in amplifier.
Thanks to their light weight and soft synthetic leather ear pads, the headsets in this series offer excellent comfort even during extended periods of use.
