Bose QuietComfort Ultra Manuel D'utilisation page 30

Noise cancellation reduces unwanted noise, providing a clearer, more lifelike
audio performance.
By default, the earbuds power on in Quiet mode. Noise cancellation is fully enabled
(see page 33).
CHANGE THE NOISE CANCELLATION SETTING
You can switch between preset noise cancellation settings by changing the mode. For
information about modes, see page 33.
NOISE CANCELLATION WHILE ON A CALL
When you make or receive a call, the earbuds remain at the current noise
cancellation setting and self voice is activated. Self voice helps you hear yourself
speak more naturally.
To adjust noise cancellation while on a call, change the mode (see page 34).
NOTES:
• Auto transparency is disabled while on a call (see page 29).
• To adjust self voice, use the Bose 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.
1. Do one of the following:
• If you're wearing the earbuds, disconnect your mobile device (see page 43).
• 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.
2. Touch and hold an earbud to change the mode (see page 34).
NOTE: To reconnect your mobile device, select the earbuds from the Bluetooth list on
your device.
