function.

2. When the power is ON, the headphone operates with noise canceling function.

3. Rewind the cord and turn the power ON to use the noise canceling function

rewinding again.

Noise Canceling Function becomes less effective as the battery wears down so make sure to 
replace the battery as necessary to maintain the proper performance of the headphones.
