Introducing QuietComfort®2 Acoustic Noise

Cancelling®headphones

Thank you for purchasing the QuietComfort 2 Acoustic Noise

Cancelling headphones from Bose. Advanced research and

development, innovative engineering, and integrated

technologies enable the headphones to reduce unwanted

noise and provide you with exceptional acoustic performance

in a comfortable, convenient package.

Insert the battery first, before you put on the headphones.

Wearing the headphones

As you put on the headphones, observe the markings that

identify the left (L) and right (R) earcups. Adjust the headband so

it rests gently on top of your head and the earcup cushions fit

comfortably around your ears.

For noise reduction and audio

Use the supplied headphones cord to enjoy both audio and

noise reduction. Please note that the LEVEL switch on the

plug is used to adjust the output volume of different audio

sources.

1. Set the LEVELswitch on the headphones cord to

appropriate setting for your audio source.

Headphones cord

LLEVEL switch.

LO Typically used for airline audio

systems or audio devices that use

A/C power.

HI Typically used for battery-powered

audio devices (CD/DVD or MP3/

digital audio players) and personal

computers.

Note: The HI and LO settings have no affect on noise reduction.

2. Insert the headphones cord into the opening on the left (L)

earcup. Push the plug in so it is flush with the side of the

earcup.

3. Connect the headphones cord to your audio source. Refer

to “Connecting to portable and home audio devices” on

page 5.

4. Put on the headphones and turn on the power switch.

5. Use the volume control on your audio source to make

further volume adjustments.

For noise reduction only

If you plan to use them for noise reduction only, simply put on

the headphones and turn on the power switch, located on the

right earcup. The headphones cord is not required.

Using Your Headphones

EnglishEnglish

Connecting to portable and home audio

devices

The 3.5 mm plug on the headphones cord

allows you to connect your headphones to a

variety of audio devices that use a single 3.5

mm output jack such as a CD, DVD, MP3/digtal

audio player, or personal computer. Set the

LEVEL switch to HI and plug the headphones

cord directly into the 3.5 mm output jack.

To connect to a home stereo system that has a ¼ in

(6.3 mm) stereo output jack, use the the ¼ in (6.3 mm)

stereo adapter plug included with your headphones. Set the

LEVEL switch to LO. Plug the headphones cord into the

adapter plug and insert it into the output jack on your stereo

system.

Connecting to airline audio systems

The audio output connections on airline audio

systems vary, but they typically have dual or

single 3.5 mm output jacks.

Note: Airline audio may not equal the high quality audio you

experience from a home stereo or portable source.

Connecting to dual output jacks

Set the LEVEL switch to LO. Plug the

headphone cord into the dual-plug adapter

and insert it into the dual output jacks.

Connecting to a single output jack

Set the LEVEL switch to LO. Plug the

headphone cord into the adapter and

insert it into the single output jack.

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.

Using Your Headphones

EnglishEnglish

Folding the earcups for storage

QuietComfort®2 Acoustic Noise Cancelling®headphones

feature rotating earcups that fold flat for easy, convenient

storage. The earcups rotate in one direction only.

CAUTION: Incorrectly rotating the earcups can damage the

headphones.

Reattaching earcup cushions

The earcup cushions are held in place by a mounting flange.

This flange snaps under small tabs located around the inside

rim of the earcup.

If an earcup cushion becomes partially or completely

detached, push its mounting flange back into the earcup. Then

use your finger or thumb to press around the edge of the

mounting flange, making sure it snaps into place all the way

around the earcup.

Care and Maintenance

EnglishEnglish

Battery replacement

Although it varies by usage, battery life averages 35 hours.

With the headphones turned on, the battery light indicator will

flash when there are approximately 8 hours of battery life

remaining.

When a replacement is needed, use 1 AAA alkaline battery

(IEC LR03). Tilt the top of the right earcup inward to gain

access to the battery compartment.

+–

Note: You can use rechargeable batteries (NiMH, composed of

nickel metal hydride, are recommended). They average half the

life of alkaline batteries. However, the low battery indicator light is

not set for such batteries and will not be a reliable indicator of

their remaining battery life.

You can purchase accessories from your Bose dealer, on the

internet (www.Bose.com), or by placing an order over the

phone. See the inside back cover for contact information.

Care and Maintenance

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.

Aviation Communication Headset Needs

While QuietComfort®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.

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 that are common to

many propeller-driven aircraft may impair the user’s ability to

receive incoming audio communications, particularly during

takeoff and climb out when noise levels are high.

• The QuietComfort 2 headphones are not engineered for the

altitude, temperature or other environmental conditions

common in non-commercial aircraft, resulting in possible

interference to critical communications.

For pilots, Bose offers a communication headset which is

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 non-commercial 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.
