Connect the headphones to the AV equipment.
AI Noise Canceling
What is noise canceling?
AI Noise Canceling is a useful function that automatically selects one
of the noise canceling modes. is function provides the most effective
noise canceling mode by immediately analyzing ambient sound
components when the AI NC button is pressed.
e noise canceling circuit actually senses outside noise with built-in
microphones and sends an equal-but-opposite canceling signal to the
headphones.
When connecting to dual or
stereo mini jacks of in-flight music
services.
Operating Instructions
Manual de instrucciones
Press the AI NC button.
• e noise canceling effect may not be pronounced in a very quiet
environment, or some noise may be heard.
• e noise canceling effect may vary depending on how you wear the
headphones.
• e 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 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.
When you press the AI NC button and the POWER switch is set to
“ON”, beep sounds come from the headphones to inform you that
the unit has started analyzing ambient sound components (approx. 3
seconds).

During analysis, sound reproduction from the unit is stopped and the
POWER indicator blinks.
When analysis is completed, the most effective noise canceling mode is
set automatically, and sound reproduction from the headphones starts.
Notes on usage
When connecting to the stereo
mini jack of a WALKMAN*, etc.
• Clean the headphones with a soſt 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 stereo headphones in a location subject to direct
sunlight, heat or moisture.

• When connecting the cord, insert the plug into the jack until the green
portion of the plug disappears.
Noise canceling mode types
NC Mode A: Noise mainly in an airplane is effectively reduced.
NC Mode B: Noise mainly in a bus or a train is effectively reduced.
NC Mode C: Noise mainly found in an office environment (PC, copier,
air ventilation, etc.) is effectively reduced.
Notes on headphones
Preventing hearing damage
Avoid using headphones at high volume. Hearing experts advise
against continuous, loud and extended play. If you experience a ringing
in your ears, reduce the volume or discontinue use.
Tips
English
• When the power of the headphones is turned on, NC Mode A is set. (See
“Noise canceling mode types” for details about NC Mode A.)
• Press the AI NC button again to reset the noise canceling mode if ambient
noise has changed, such as when you move outdoors from a room.
• To disconnect the cord, pull it out by the plug, not the cord, as the inner
conductors may break.
Do not use headphones while driving and cycling, etc.
As headphones reduce outside sounds, they may cause a traffic
accident. Also, avoid listening with your headphones in situations
where hearing must not be impaired, for example, a railroad crossing, a
construction site, etc.

for safety
Press the MONITOR button while the POWER switch is set to “ON”,
playback silences, and you can hear the surrounding environment.
To cancel this function, press the MONITOR button again.
In particularly dry air conditions, noise or sound skipping may occur,
or mild tingling may be felt on your ears. is is a result of static
electricity accumulated in the body, and not a malfunction of the
headphones.
To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.
e effect can be minimized by wearing clothes made from natural
