airplane, see “Connecting to in-flight entertainment
systems” on page 4.

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.
