What is the Noise Cancellation optimizer function?

1. Wear the headset with the power turned on.

2. Activate NC mode

3. Press and hold the NC/AMBIENT/C (custom) button until you hear voice guidance “Optimizer start” (about 2 seconds).

   Test signals can be heard during the optimization. When the optimization is finished, you will hear a voice guidance “Optimizer finished”.

When you wear the headset, this function always automatically optimizes the noise canceling performance by analyzing the wearing condition of the headset according to the shape of your face and your hairstyle, or the presence or absence of glasses, and the pressure change in an airplane, etc.

There is no need for the wearer to press a button or use the touch sensor control panel to use this function.

Because the noise canceling performance is automatically optimized by the Auto NC Optimizer function according to changes in the wearing condition and usage environment, you may notice fluctuations in the noise canceling effect.
