You can use the headphones with a variety of audio  
sources: airline audio, a CD, DVD or MP3 player,  
a personal or laptop computer, or home stereo.  
The maximum input voltage is 9 Vrms.  
To enjoy both noise reduction and audio:  
Note: The LO setting of the LEVEL switch lowers the volume  
levels of strong audio output signals which are common on  
airline systems. If you find that the volume level is too low,  
set the LEVEL switch to HI. The switch has no effect on noise  
reduction performance.  
1. Gently push the headphones plug all the way into  
the connector opening on the left earcup, until the  
plug housing is flush with the earcup.  
3. Put on the headphones. On the right earcup, slide  
the power switch forward to the On position. The  
battery light indicator will illuminate.

Connecting to in-flight entertainment  
systems  
Audio jack configurations on airplanes vary. Notice the  
jack configurations in the chart below.  
A single, 3.5 mm jack  
(on most portable sources)  
Use the single plug.  
No adapter needed.  
Note: Airline audio may not equal the high quality audio you can  
get from a home stereo or a portable source.  
One 3.5 mm jack and one power jack  
Use the single plug in the 3.5 mm jack  
(the larger one).  
WARNING: Use only the Bose® airline adapter to connect  
headphone to airplane seat jacks. DO NOT use adapters  
intended for mobile phones to connect to the airline seat jack,  
as this could result in personal injury such as burns or property  
damage due to overheating. Remove and disconnect  
immediately if you experience warming sensation or loss  
of audio.  
The smaller jack does not need a  
connection.  
Two 3.5 mm jacks  
Use the dual 3.5 mm output plug  
adapter.  
One power jack and two 3.5 mm jacks  
Use the dual 3.5 mm output plug  
adapter for the two 3.5 mm jacks.  
The power jack does not need a  
connection.

Storing the headphones  
To store the headphones in the case, rotate the  
earcups inward, then place the headphones in  
the case.  
Battery life and replacement  
Although it varies by usage, battery life averages 35  
hours. The battery light indicator starts flashing when  
there are approximately 5 hours of battery life remaining.  
When a replacement is needed, use a AAA alkaline  
battery (IEC LR03).  
Note: Remaining battery life may vary when using rechargeable  
batteries. NiMH batteries, composed of nickel metal hydride,  
are recommended.  
Cleaning the headphones  
Scheduled cleaning is not required. However, you can  
simply wipe the outside surfaces with a damp cloth,  
as needed. Also, be sure that the earcup ports are clear  
and that no moisture is allowed into the earcups.  
CAUTION: Incorrectly rotating the earcups can damage the  
headphones.

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.  
WARNING: Except in case of emergency, Bose recom-  
mends that you NOT use these headphones as aviation  
communication headsets because:  
• No incoming audio will be heard with a discharged  
or improperly installed battery. This could result in  
the potential of missed communications while piloting  
an aircraft.  
• Extremely loud ambient noise levels common to many  
propeller-driven aircraft may impair your ability to  
receive incoming audio communications, particularly  
during takeoff and climb out.  
• The QuietComfort 15 headphones are not engineered  
for noise conditions, altitude, temperature or other  
environmental conditions common in non-commercial  
aircraft, resulting in possible interference to critical  
communications.  
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.
