What is noise canceling?

The noise canceling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the unit.

  • The noise canceling effect may not be pronounced in a very quiet environment, or some noise may be heard.

  • The noise canceling effect may vary depending on how you wear the unit.

  • The noise canceling function works for noise in the low frequency band primarily. Although noise is reduced, it is not canceled completely.

  • When you use the unit in a train or a car, noise may occur depending on street conditions.

  • Mobile phones may cause interference and noise. Should this occur, locate the unit further away from the mobile phone.

  • Do not cover the microphones of the headphones (MIC) with your hands. The noise canceling function may not work properly.
