CONNECTING TO IN-FLIGHT ENTERTAINMENT SYSTEMS…
To connect to in-flight entertainment systems equipped with dual output connectors, use the supplied dual 3.5mm airline
adaptor and the standard analogue cable.
NOTE:
• Audio output jack configurations may vary on airplanes. Airline audio quality may not equal what your home audio
equipment, or portable sources provide.
• The supplied conversion plug may not be usable depending on the type of aircraft.
• Do not use these headphones when the use of electric devices on the aircraft is prohibited, or when the use of
personal headphones to listen to on-board music service is prohibited.
WARNING
PSB Speakers recommends you do not use these headphones as aviation communication equipment. They are not
engineered for many environmental conditions common in commercial or non-commercial aircraft (including, but not
limited to: altitude, temperature, noise conditions, unpressurized aircraft) and could result in possible interference to critical
communications.
WARNING
Liquids or cleaning solvents can cause irreparable damage to the electronics inside your headphones. The M4U warranty
does not cover such damage.
