How do I change the directivity setting?

Press the ▲ and ▼ buttons simultaneously. Keep pressing to cycle through modes: Everywhere (low tone) for all directions, Front (medium tone) to focus on sounds in front, and Focused (high tone) for conversations in noisy settings.

What should I do if the headphones don't charge?

Ensure the USB cable is securely connected to the headphones and a power source. Check that the headphones are at room temperature (50°F to 104°F). If the battery indicator blinks red, the battery needs charging. If you see a solid red indicator, contact Bose customer service.

How do I clean the StayHear+ tips?

Choosing the correct StayHear®+ tip

For optimal audio performance, it is important to choose the correct size StayHear®+ tip. Select the size that gives you the best comfort and fit in each ear. To determine the best fit, you may need to try all three sizes. You may need a different size for each ear.

Note: Make sure your tips fit properly to avoid the earbuds whistling.

Each tip and earbud is marked with either an L or an R. Be sure to attach the left tip to the left earbud and the right tip to the right earbud.

Illustration of two earbuds with labeled 'R' and a connector pin (no text or symbols beyond labels)

Fitting the earbuds to your ear

The tip allows the earbud to rest comfortably and securely in your ear. The tip wing fits just under your ear ridge.

1. Insert the earbud so the tip gently rests in the opening of the ear canal.
2. Tilt the earbud back and tuck the tip wing under the ear ridge until it is secure.

Changing the StayHear®+ tips

1. Holding the earbud by the stem, gently grasp the attached StayHear®+ tip and peel it away from the earbud.

CAUTION: To prevent tearing, grasp the tip by its base. Do not pull on the tip wing.

1. Align the opening of the new tip with the earbud nozzle and rotate the tip onto the nozzle. Press the base of the tip until it clicks securely into place.

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.

How World Volume works

• 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.

Using the headphones for World Volume only

If you want to use the headphones for World Volume only, do one of the following:

• Pause or stop audio (see page 11).
• Disconnect your mobile device (see page 24). You may want to do this if you prefer to keep your mobile device in another room or powered off while using the headphones.

Note: Certain conversation-enhancement settings are only available in the Bose® Hear app. While your device is disconnected, you won't be able to adjust these settings. However, you can still adjust World Volume and directivity by using the headphone controls (see page 10).

Getting used to new sounds

Bose® Hearphones™ may require you to get used to new, higher-frequency sounds and your voice sounding different. When powering on your headphones for the first time, 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).

Adjusting sound direction

You can adjust the microphone arrays on the earbuds to focus on sounds coming from different areas in your environment.

To focus on sounds coming from a particular area, press the World Volume buttons ▲ and ▼simultaneously. You hear a tone representing the new directivity setting. Repeat to cycle through directivity settings until you hear the tone for your preferred setting.

Line drawing of a finger pressing a device with arrows indicating direction (no text or symbols)

• Everywhere (low-frequency tone): Hear sounds from all directions. Use this setting when crossing the street, watching television or listening to music.
• Front (medium-frequency tone): Concentrate on sounds coming from a wide area in front of you and reduce noise from behind. Use this setting when having a conversation with more than one person.
• Focused (high-frequency tone): Focus on sounds coming from a narrow area in front of you. Use this setting when having a conversation with someone in a noisy setting.

Bluetooth wireless technology lets you stream music from mobile devices such as smartphones, tablets and laptop computers. Before you can stream music from a mobile device, you must pair the device with your headphones.

Pairing your mobile device using the Bose® Hear app (recommended)

1. Power on your headphones (see page 8).
2. Download the Bose® Hear app, and follow the on-screen instructions.

Once paired, if wearing the headphones, you hear "Connected to ." If holding the headphones, you see the Bluetooth indicator glow solid white.

Choosing an alternative pairing method

If you are unable to pair your mobile device using the Bose® Hear app, you can pair using the Bluetooth settings menu or Near Field Communication (NFC).

What is NFC?

NFC enables a Bluetooth connection by simply tapping two devices together. Refer to your device owner's guide to see if your model supports NFC.

If your device does not supportBluetooth pairing via NFC or if you are unsure:	Follow the instructions for “Pairing your mobile device using theBluetooth menu” on page 21.
If your device supportsBluetooth pairing using NFC:	Follow the instructions for “Pairing your mobile device using NFC” on page 23.
