eduction

Put on the headphones. Then slide the power switch forward to the On position. The battery light indicator will illuminate.

You do not need to connect the headphones cord for noise reduction only operation.
For noise reduction and audio

To enjoy both noise reduction and audio:

Gently push the headphones plug all the way into the connector opening until the plug housing is flush with the earcup.
Connect the headphones cord to an audio source.
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.
Put on the headphones. Then slide the power switch forward to the On position. The battery light indicator will illuminate.

Using the adapter plugs
To connect to in-flight entertainment systems equipped with dual output connectors, use the dual 3.5 mm output plug.

Note: If you find that the volume level is too low, remove the adaptor plug and plug the headphone directly into the 3.5 mm output connector.
To connect to an audio device that has a ¼ in (6.3 mm) stereo output connector, use the stereo adapter plug.

Storing the headphones
To store the headphones in the case, rotate the earcups inward, then place the headphones in the case.

CAUTION: Incorrectly rotating the earcups can damage the headphones.
Battery life and replacement
Although it varies by usage, battery life averages 40 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.
Reattaching the earcup cushions If a cushion becomes partially or completely detached:

Push its mounting rim back into the earcup .
Press around the edge of the mounting rim, making sure it snaps into place all the way around the earcup.

Other Considerations

WARNING: Except in case of emergency, Bose recommends 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 Quiet Comfort 2 headphones are not engineered for altitude, temperature or other environmental conditions common in non-commercial aircraft, resulting in possible interference to critical communications.

Quiet Comfort® 2 headphones are designed for passenger use in air transport aircraft. They are not engineered to meet the needs of pilots or to meet civil aviation authority standards for communication headsets.
For pilots, Bose offers a communication headset specifically designed to meet or exceed civil authority standards. It features a microphone with the appropriate power and intelligibility for transmission of flight information. It is also engineered to withstand the altitude and temperature conditions that are common in noncommercial aircraft. For more information on products for pilots, please contact Bose Corporation using the information supplied on the inside back cover of this owner’s guide.
