Other Considerations
QuietComfort® 15 headphones are designed for
passenger use on jet aircraft. They are not engineered
to meet the needs of pilots and crew members or to
meet civil aviation authority standards for
communication headsets.
For pilots and and crew members who require
communication headsets, Bose® offers an aviation
headset specifically designed to meet or exceed
civil authority standards. It features a microphone
with the appropriate power and intelligibility for
critical communication needs. It is also engineered
to withstand the environmental conditions that are
common in unpressurized aircraft.
