Follow the app instructions.

ADD THE EARBUDS TO AN EXISTING ACCOUNT

To add your Bose QuietComfort Earbuds II, open the Bose Music app and add your earbuds.
SWEAT AND WEATHER RESISTANCE
The earbuds are rated IPX4 water resistant. They are designed to be sweat and weather resistant but aren’t meant to be submerged underwater.

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 normal wear

HOW TO WEAR

INSERT THE EARBUDS

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).

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.
Check the fit
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 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

Holding the earbud, gently squeeze the eartip and peel it away from the earbud.
- CAUTION: To prevent tearing, do NOT pull on the edge of the eartip.
Choose a new eartip size (see page 19).
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.
Repeat steps 1 – 3 for the other earbud, as needed.
NOTE: You may need to use a different size eartip for each ear.
Insert the earbuds.
Check the fit.

NOTES:

If you change the eartip, you may need to change the stability band so the band rests comfortably against your ear ridge
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

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.
Choose a new band size.
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.
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.
Press down until the band fits securely into place.
Repeat steps 1 – 5 for the other earbud, as needed.
- NOTE: You may need to use a different size band for each ear.
Insert the earbuds
Check the fit
