IMMERSIVE AUDIO
Immersive audio takes what you’re hearing out of your head and places it in front of
you—like you’re always in the acoustic sweet spot. It feels like the sound is coming
from outside the headphones, resulting in a more natural listening experience.
Immersive audio works on any streaming content from any source, taking it to new
heights with beer sound clarity and richer sound quality.
NOTE: When you make or receive a phone call, immersive audio is temporarily set
to O (see page 24).
IMMERSIVE AUDIO SETTINGS
SETTING DESCRIPTION WHEN TO USE
Motion
Audio sounds like it's coming from two
stereo speakers in front of you that
follow the movements of your head.
NOTE: This seing is used by default
in Immersion mode.
Use for the most consistent
experience. Best for when you’re
doing activities that require you
to frequently turn your head or
look down.
Still
Audio sounds like it's coming from two
stereo speakers in front of you that
stay where they are when you move
your head.
NOTES:

your head, the speakers recenter on
your position.
• To access this option, use the Bose
Music app. Tap Immersive Audio on
the main screen.

your headphones.

— or create up to seven of your own custom modes.

block out distractions using the highest level of noise cancellation.

Aware mode with ActiveSense
The dynamic noise cancellation of Aware mode with ActiveSense technology allows
you to hear your surroundings while reducing unwanted noise.

cancellation when sudden or loud noises occur near you, so you can maintain
awareness without intermient noise interrupting your audio. Once the noise stops,
noise cancellation automatically returns the previous seing.
