Notes on use

What is noise-canceling?
The noise cancelling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headphones.

Notes on the noise canceling function

• Adjust the earpads so that they cover your ears, otherwise noise canceling will not function properly.
• The noise cancelling effect may vary depending on how you wear the headphones.
• Do not cover the microphone of the headphones with your hands. The noise canceling function may not work properly.
• After you turn on the power of the headphones, you may hear a slight hiss. This is the operating sound of the noise cancelling function, not a malfunction.
• The noise cancelling function works for noise in the low frequency band primarily. Although noise is reduced, it is not cancelled completely.
• The noise cancelling effect may not be pronounced in a very quiet environment, or some noise may be heard.
• When you use the headphones 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 headphones further away from the mobile phone.
