Active Noise Cancellation (ANC)
The Active Noise Cancellation feature can be turned on or off at any time
by simply pressing the ANC toggle button. A short beep can also be
heard to signal this activity.
ANC LED Description
Solid ANC is active
Off ANC is off
Listeners will also enjoy the fact that you can keep ANC mode enabled even without a music source playing.
This is designed for periods when you want to simply silence your surroundings (ex. airplane). Note, however
that the headphones will automatically turn off to conserve battery life when ANC is active AND there is 3 hours
of inactivity (no music playing + no button presses).

With 100% charge, the Symphony 1’s battery will last up to 10 hours when powered on with ANC enabled
and at full volume, and up to 15 hours with ANC disabled and at full volume.
