Frequently Asked Questions - QuietComfort Ultra Headphones BOSE

How do I connect the earbuds to my smartphone?

Open the charging case and press and hold the button on the back until the LED slowly flashes blue. Enable Bluetooth on your smartphone and select Bose QC Ultra Earbuds from the list. You can also use the Bose Music app for guided setup.

How long does the earbud battery last?

With immersive audio off, battery life is up to 6 hours. With immersive audio on, it's about 4 hours. A quick 20-minute charge in the case provides up to 2 hours of listening.

What if the sound quality is poor?

First check the fit of the ear tips using the test tool in the Bose Music app. Clean the ear tips and nozzles. Make sure the device is connected via the A2DP stereo profile. Turn Bluetooth off and on again, or clear the device list.

How do I change the size of the ear tips or stability bands?

For ear tips, hold the earbud, flatten the ear tip and gently pull. Align the new ear tip onto the nozzle and push until it clicks. For stability bands, slide the ring over the ear tip, then align the band's dot with the gray dot on the earbud. Use the provided sizes (S, M, L for ear tips; 1, 2, 3 for bands).

The earbuds aren't charging, what should I do?

Make sure the charging contacts are clean and the earbuds are properly placed in the case. Check that the USB cable is securely connected. Try a different cable or wall charger. If the case isn't charging, leave it plugged in for at least 30 minutes to initiate charging.

How do I reset the earbuds to factory settings?

Place the earbuds in the open case. Press and hold the back button for 25 seconds until the LED flashes white twice, then slowly flashes blue. Repeat this process three times: the third time, the LED will flash orange for 3 seconds to confirm the reset.

Touch controls are not responding, what should I do?

Make sure you are pressing the outer touch surface. Ensure your hands are dry and you are not wearing gloves. If the earbuds are cold or hot, wait until they return to room temperature. Restart the earbuds by placing them in the case and closing/opening it.

How do I use immersive audio?

Immersive audio creates a sound stage in front of you. Use the Bose Music app to choose between Still mode (speakers stay fixed) and Motion mode (they follow your head). You can also use a touch shortcut by holding one earbud to cycle through settings.

Are the earbuds water resistant?

Yes, they are rated IPX4, protecting against sweat and splashes. Do not submerge them in water, swim, or shower with them. Regularly clean the charging contacts with a dry cotton swab to prevent corrosion.

How do I clean the earbuds and case?

Remove the ear tips and stability bands, wash them with warm soapy water, rinse and dry completely before reattaching. Use a dry cotton swab to clean the nozzles and charging contacts. Clean the case with a dry cloth. Do not use abrasive products.

Using the app, you can verify the earbud fit, manage Bluetooth connections, manage earbud settings, adjust the audio, choose your voice prompt language, and get updates and new features.

NOTE: If you have already created a Bose account for another Bose product, see "Add the earbuds to an existing account."

DOWNLOAD THE BOSE MUSIC APP

1. On your mobile device, download the Bose Music app.

NOTE: If you're located in Mainland China, download the Bose音乐 app.

1. Follow the app instructions.

ADD THE EARBUDS TO AN EXISTING ACCOUNT

To add your Bose QuietComfort Ultra Earbuds, open the Bose Music app and add your earbuds.

The earbuds are rated IPX4 water resistant. They are designed to be sweat and weather resistant but aren't meant to be submerged under water.

CAUTIONS:

- Do NOT swim or shower with the earbuds.

- Do NOT submerge the earbuds.

NOTES:

• To prevent corrosion, regularly clean the charging contacts on the earbuds with a dry, soft cotton swab or equivalent.
• IPX4 isn't a permanent condition, and resistance might decrease as a result of normalwear.

INSERT THE EARBUDS

1. Insert the earbud so the eartip gently rests at the opening of your ear canal.

NOTE: Each earbud is marked with either an R (right) or L (left).

1. 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.

NOTE: You may need to rotate the earbud back and forth for the eartip to create a comfortable seal. However, rotating it too far back or forward may impact audio and microphone sound quality.

1. Check the fit (see page 15).
2. Repeat steps 1 – 3 to insert the other earbud.

When you insert the earbuds, the audio is personalized 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 personalization 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 Earbud Seal Test in the Bose Music app. You can access this option from the Settings menu.

Eartips

FIT WHAT TO CHECK

Proper fit		The eartip gently rests at the opening of your ear canal to create a comfortable seal. Background noise should sound muffled. NOTE: Noise cancellation may impact the ability to hear muffled noise.
Too much pressure		The eartip feels uncomfortable and squished in your ear canal.
Too loose		The eartip rests too deep in your ear canal, feels loose in your ear, or falls out when you move your head.

Stability bands

FIT WHAT TO CHECK

Proper fit		The band doesn't stick out or feel squished against your ear ridge.
Too big		The band is sticking out or feels squished under your ear ridge.
Too small		The band doesn't reach your ear ridge.

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

Three sizes of eartips are included with the earbuds: 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.

Squeeze and peel Separate

CAUTION: To prevent tearing, do NOT pull on the edge of the eartip.

1. Choose a new eartip size (see page 17).

2. 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.

Align Press

1. Repeat steps 1 - 3 for the other earbud, as needed.

NOTE: You may need to use a different size eartip for each ear.

1. Insert the earbuds (see page 14).

2. Check the fit (see page 15).

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 19).

• To see how-to videos about changing the eartips, visit: support.Bose.com/QCUE

- If you need additional eartip sizes, contact Bose customer service or visit: ____support.Bose.com/QCUE

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.

CAUTION: To prevent tearing, do NOT pull on the thin part of the band.

1. Choose a new band size (see page 17). Select the band marked with either an R (right) or L (left), depending on the earbud.

2. With the band markings facing you and the band scoop facing away from you, align the dot on the band with the gray dot on the bottom of the earbud.

3. Gently stretch the band over the eartip, making sure the dots align and the tab on the band fits in the notch on the top of the earbud.

NOTE: Aligning the band correctly makes sure that the hole on the side of the band is over the earbud microphone so the microphone isn't blocked.

1. Press down until the band fits securely into place, then check for alignment.

1. Repeat steps 1 - 5 for the other earbud, as needed.

NOTE: You may need to use a different size band for each ear.

To adjust noise cancellation while on a call, change the mode (see page 33).

NOTES:

• Auto transparency is disabled while on a call (see page 28).
• To adjust self voice, use the Bose Music app. You can access this option from the Settings menu.

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

1. Do one of the following:

2. If you're wearing the earbuds, disconnect your mobile device (see page 41).

3. If the earbuds are in the charging case, turn the Bluetooth feature off on your mobile device. Then, remove the earbuds from the case and insert them in your ears.

4. Touch and hold an earbud to change the mode (see page 33).

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

Immersive audio takes what you're hearing out of your head and places it in front of you—like you're always in the sound's sweet spot. It feels like the sound is coming from outside the earbuds, resulting in a more natural listening experience. Immersive audio works on any streaming content from any source, taking it to new heights with better sound clarity and richer sound quality.

NOTE: When you make or receive a phone call, immersive audio is temporarily set to Off (see page 31).

1. Remove the earbuds from the Bluetooth list on your device.

2. With the earbuds in the charging case and the case open, press and hold the button on the back of the case for 25 seconds until the earbuds status light blinks white 2 times, slowly blinks blue, and then turns off.

NOTE: Make sure both earbuds are in the case and the case is open.

When the reboot is complete, the earbuds status light glows according to the charging status (see page 38), and the charging case status light glows according to the battery level (see page 39).

RESTORE THE EARBUDS TO FACTORY SETTINGS

A restore to factory settings clears all settings and return the earbuds to their original out-of-box state. After, the earbuds can be configured as if they were being set up for the first time.

Restoring to factory settings is only recommended if you are having issues with the earbuds or you have been instructed to do so by Bose customer service.

1. Remove the earbuds from the Bluetooth list on your device.
2. Remove the earbuds from your Bose account using the Bose Music app.

NOTE: For more information about how to remove the earbuds from your Bose account using the Bose Music app, visit: ____support.Bose.cor

1. With the earbuds in the charging case and the case open, press and hold the button on the back of the case for 25 seconds until the earbuds status light blinks white 2 times, slowly blinks blue, and then turns off.

NOTE: Make sure both earbuds are in the case and the case is open.

1. Repeat the previous step 2 more times.

After the third time, the status light blinks amber for 3 seconds to indicate factory settings are being restored.

When the restore is complete, the status light slowly blinks blue. The earbuds are now in their original out-of-box state.
