CONTENTS

Confirm that the following parts are included:

1. Bose QuietComfort Earbuds II
2. Charging case
3. Eartips (sizes small and large)
4. Stability bands (sizes 2 and 3)
5. USB Type-C® to USB-A cable

HOW TO WEAR

INSERT THE EARBUDS

1. Insert the earbud so the eartip gently rests at the opening of your ear canal.
2. Slightly rotate the earbud back until the eartip creates a comfortable seal at your ear canal and the stability band rests against your ear ridge.
3. Check the fit (see page 17).
4. Repeat steps 1–3 to insert the other earbud.

When you insert the earbuds, the audio is personalised to your ears for the best audio performance and noise cancellation. NOTE: If you’re sharing the earbuds, place them in the charging case to clear the audio personalisation between each user.

CHECK YOUR FIT

For the best fit, audio performance, and noise cancellation, use a mirror to make sure you’re using the correct size eartips and stability bands. You may need to try a different size eartip or stability band for each ear. TIP: You can also check your fit using the Eartip Fit Test in the Bose Music app. You can access this option from the Settings menu.

Eartips

Stability bands

TRY ANOTHER SIZE

Wear the earbuds for an extended period of time. If the earbuds don’t feel comfortable or secure, or noise cancellation or sound quality isn’t as expected, try another size eartip or stability band. You may need to try all three eartip or band sizes, or use a different size eartip or band for each ear.

Eartips

The eartips come in small, medium, and large. Medium eartips come attached to the earbuds. If they feel too small, try large eartips. If they feel too big, try small eartips.

Stability bands

The stability bands are marked with size 1 (small), 2 (medium), or 3 (large) and an R (right) or L (left). Size 1 bands come attached to the earbuds. If they feel too small, try size 2 bands.

CHANGE THE EARTIPS

1. Holding the earbud, gently squeeze the eartip and peel it away from the earbud.
2. Choose a new eartip size (see page 19).
3. Align the eartip with the earbud nozzle and press the eartip onto the nozzle until you feel it snap securely into place and hear it click.
4. Repeat steps 1–3 for the other earbud, as needed. NOTE: You may need to use a different size eartip for each ear.
5. Insert the earbuds (see page 16).
6. Check the fit (see page 17).

NOTES:

• If you change the eartip, you may need to change the stability band so the band rests comfortably against your ear ridge (see page 21).
• To see how-to videos about changing the eartips, visit: support.Bose.com/QCEii
• If you need additional eartip sizes, contact Bose customer service or visit: support.Bose.com/QCEii

CHANGE THE STABILITY BANDS

1. Holding the earbud, gently grab the stability band scoop and peel the band toward you, over the eartip, and away from the earbud.
2. Choose a new band size (see page 19).
3. With the band markings facing you and the band scoop facing away from you, align the dot on the band with the grey dot on the bottom of the earbud.
4. Gently stretch the band over the eartip, making sure the dots align and the microphone hole on the band is over the microphone on the earbud so the microphone isn’t blocked.
5. Press down until the band fits securely into place.
6. Repeat steps 1–5 for the other earbud, as needed. NOTE: You may need to use a different size band for each ear.
7. Insert the earbuds (see page 16).
8. Check the fit (see page 17).

POWER

POWER ON

Open the charging case. The earbuds power on. The earbuds’ status light blinks white and then glows according to the charging status (see page 36). The charging case status light glows according to the battery level (see page 37).
NOTE: When you remove the earbuds from the charging case, close the case to help preserve the battery life and keep the case free of debris.

POWER OFF

1. Place both earbuds in the charging case.
2. Close the case.

The earbuds power off. The charging case status light glows according to the battery level (see page 37). NOTE: The earbuds disconnect from your device when they are placed in the case.

STANDBY

Standby conserves the earbud battery when an earbud is out of the case and not in use. The earbud switches to Standby when you remove the earbud from your ear for 10 minutes. To wake the earbud, insert the earbud into your ear. Use touch control by tapping or swiping the touch surface of either earbud. With touch control, you can play/pause audio, change the volume, perform basic call functions, adjust noise cancellation, and use a Shortcut (see page 28).

IN-EAR DETECTION

In-Ear Detection uses sensors to identify when you’re wearing both earbuds or just a single earbud. You can automatically play/pause audio, answer phone calls (if enabled), and adjust noise cancellation by inserting or removing an earbud. NOTE: To manage In-Ear Detection features, use the Bose Music app. You can access this option from the Settings menu.

AUTO PLAY/PAUSE

When you remove an earbud, the audio pauses on both earbuds. To resume audio, reinsert the earbud. NOTE: If you want to use a single earbud, you can tap the earbud in your ear to resume audio.

AUTO ANSWER CALL

You can answer phone calls by inserting an earbud. NOTE: To enable this feature, use the Bose Music app. You can access this option from the Settings menu.

AUTO TRANSPARENCY

When you remove an earbud, the noise-cancelling mode adjusts to Aware Mode on the earbud in your other ear (see page 30). When you reinsert the earbud, the earbud in your ear adjusts to the previous noise-cancelling level. NOTE: If you want to use a single earbud, you can use your Shortcut to cycle through the noise-cancelling modes and choose the appropriate mode.

NOISE CANCELLATION

Noise cancelling reduces unwanted noise, providing a clearer and more lifelike audio performance. You can choose between two pre-configured noise-cancelling modes, Quiet and Aware, or create up to two of your own custom modes. Quiet Mode allows you to block out distractions using the highest level of noise cancellation. Aware Mode provides full transparency and allows you to hear your surroundings while enjoying your audio. Aware Mode also includes ActiveSense™ technology to reduce sudden or loud noises. Choose your noise-cancelling mode based on your listening preferences.

NOISE CANCELLING MODES

NOTE: By default, the earbuds power on in Quiet Mode. To set the earbuds to power on with the last mode used, use the Bose Music app. To access this option, tap Modes on the main screen.

Aware Mode with ActiveSense™

The dynamic noise cancellation of Aware Mode with ActiveSense™ technology allows you to hear your surroundings while reducing unwanted noise. Aware Mode with ActiveSense™ allows the earbuds to automatically turn on noise cancellation when sudden or loud noises occur near you, so you can maintain awareness without intermittent noise interrupting your audio. Once the noise stops, noise cancellation automatically turns off again. NOTE: To disable ActiveSense™, use the Bose Music app. To access this option, tap Modes on the main screen, then tap Aware.

CHANGE NOISE CANCELLING MODE

To cycle through the noise-cancelling modes, touch and hold an earbud. A voice prompt announces the selected noise-cancelling mode. NOTE: To change the noise-cancelling mode using the earbuds, it must be set as a Shortcut (see page 28). TIP: You can also change the noise-cancelling mode using the Bose Music app. You can access this option from the main screen.

NOISE CANCELLATION WHILE ON A CALL

When you receive a call, the earbuds remain in the current noise-cancelling mode and Self Voice is activated. Self Voice helps you hear yourself speak more naturally. To adjust the noise-cancelling mode while on a call, touch and hold an earbud.

NOTES:

• Auto Transparency is disabled while on a call (see page 29).
• To adjust Self Voice, use the Bose Music app. You can access this option from the Settings menu.

USE NOISE CANCELLATION ONLY

You can use noise cancellation only, without audio or interruptions from phone calls.

• Do one of the following:
• If you’re wearing the earbuds, disconnect your mobile device (see page 39).
• If the earbuds are in the charging case, turn the Bluetooth feature off on your mobile device and then remove the earbuds from the case.
• Touch and hold an earbud to change the noise-cancelling mode (see “Change noise-cancelling mode”).

NOTE: To reconnect your mobile device, select the earbuds from the Bluetooth list on your device.
