NOISE CANCELLATION
Noise cancelling reduces unwanted noise, providing a clearer and more lifelike audio
performance. You can choose between two pre-configured noise cancelling modes,
Quiet and Aware, or create up to two of your own custom modes.
Quiet Mode allows you to block out distractions using the highest level of
noise cancellation.
Aware Mode provides full transparency and allows you to hear your surroundings
while enjoying your audio.
Aware Mode also includes ActiveSense™ technology to reduce sudden or loud noises.
Choose your noise cancelling mode based on your listening preferences
and environment.
