CONTENTS
Confirm that the following parts are included:

EARBUD CONTROLS

A button is located on the top of the barrel-shaped part of each earbud. The buttons control media playback, volume, phone calls, and your shortcut (see page 20).

NOTE: You can use either earbud button to control all functions except for volume. When controlling volume, the left and right earbud buttons have different functions (see page 18).

MEDIA PLAYBACK

VOLUME FUNCTIONS

TIP: You can also increase or decrease the volume using the volume controls on your device or in the Bose app.

Auto Volume
The earbuds can automatically adjust audio volume depending on the level of noise around you. This helps your audio stay at a consistent volume relative to your surroundings.

When Auto Volume is enabled and the noise level increases above your baseline volume setting, audio volume increases proportionally after a few seconds. When the noise level decreases, audio volume returns to your baseline setting.

NOTES:

It may take several seconds for audio volume to increase in response to noise.
When you make or receive a phone call, Auto Volume is temporarily disabled. When you end the call, Auto Volume returns to its previous setting.

Enable Auto Volume

Auto Volume is disabled by default. To enable Auto Volume, use the Bose app. You can access this option from the Settings menu.
Manually adjust volume when Auto Volume is enabled
To manually adjust volume, use the earbud controls (see “Volume functions”) or the volume controls on your device until you hear the volume change.

NOTE: If the earbuds are actively increasing audio volume due to noise, manually adjusting volume may have a minimal or only temporary effect unless you increase the baseline setting above the current level. To decrease volume in this situation, disable Auto Volume using the Bose app.

PHONE CALLS

Call notifications

A voice prompt announces incoming callers and call status.
To stop call notifications, disable voice prompts using the Bose app. You can access this option from the Settings menu.

ADJUST THE AUDIO EQ
To adjust the bass, midrange, and treble, use the Bose app. You can access these options from the product control screen.

NOTE: At high volumes, the effects of these adjustments may be reduced to avoid distortion.
