Headphones for Aircraft Intercom and Radio Systems
The Lightweight Headphones series was developed for use in the cockpit, and these headphones are components of the onboard communication and radio system. The series is certified according to ETSO C57a & C58a (equivalent to ETSO C139a) and is used in the Airbus A350 as well as the Airbus A320 family.
Thanks to their low weight and soft synthetic leather ear pads, the headsets in this series offer excellent wearing comfort even over long periods.
