Notes on use

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 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-canceling 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 canceling function, not a malfunction.

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

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

• When you use the headphones on 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.

Notes on using on the airplane
Do not use the headphones when use of electronic equipment is prohibited or when the use of personal headphones for in-flight entertainment services is prohibited.

Notes on handling

• Because the headphones are designed to fit closely in your ears, forcing them against your ears may result in eardrum damage. Avoid using the headphones where they are liable to be struck by people or other objects, such as a ball, etc.
• Pressing the headphones against your ears may produce a diaphragm click sound. This is not a malfunction.
• Clean the headphones with a soft dry cloth.
• Do not leave the plug dirty otherwise, the sound may be distorted.
• Be sure to consult a Sony dealer when the earpads become dirty or damaged, or when the headphones require repair work.
• Do not leave the headphones in a location subject to direct sunlight, heat, or moisture.
• Do not subject the headphones to excessive shock.
• Handle the driver units carefully.
• If you feel drowsy or sick while using these headphones, stop use immediately.
