can access this option from the Seings menu.

for each ear.

NOISE CANCELLATION
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 32).
CHANGE THE NOISE CANCELLATION SETTING
You can switch between preset noise cancellation seings by changing the mode. For
information about modes, see page 32.
NOISE CANCELLATION WHILE ON A CALL
When you make or receive a call, the earbuds remain at the current noise
cancellation seing and self voice is activated. Self voice helps you hear yourself

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

mobile device. Then, remove the earbuds from the case and insert them in
your ears.
