World Volume uses adjustable noise cancelling to control the loudness of live voices,

television, movies and other environmental sounds. You can adjust World Volume so it is

at the right level for your current activity.

• As you increase World Volume, quiet sounds in the environment are amplified more

than loud sounds so that all sounds can be heard comfortably.

• As you decrease World Volume, sounds in the environment are reduced, enabling you

to focus on your activity, for example, listening to music or podcasts, reading or using

your mobile device.

Bose

Hearphones™ may require you getting used to new, higher-frequency sounds and

your voice sounding different. When first powering on your headphones, World Volume

is set so that sounds are amplified at a slightly higher level than if you were not using

the headphones.

In some cases, you may experience the perception that a loud environment is quiet and

your voice is loud, which may cause you to lower your voice. Practice listening to new

sounds and talking on your own or with a trusted partner in a familiar environment,

before you use your headphones for conversation.

Tip: If you want to use just one earbud while getting used to new sounds, you can

mute the other earbud with the Bose Hear app (see page 9).
