Other needs
These headphones are not engineered to meet the 
needs of pilots or to meet civil aviation authority 
standards for aviation communications.  
For that purpose, Bose offers the Aviation Headset    , 
which features a microphone with the appropriate power 
and intelligibility for transmission of flight information. It is 
engineered to withstand the altitude and temperature 
conditions common in non-commercial aircraft.
