Microphone
Aer you turn on the power of the headphones, you may hear a slight
hiss. is is the operating sound of the noise canceling function, not a
malfunction.
Because the headphones are of a high density enclosure, 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. is is not a malfunction.
4 Turn on the power of the AV equipment.
Notes on using on the airplane
e supplied plug adaptor can be connected to the dual or stereo mini
jacks of in-ight music services.

Do not use the headphones when use of electronic equipment is
prohibited or when use of personal headphones for in-ight music
services is prohibited.
Utilizing the AI Noise Canceling
AI Noise Canceling
AI Noise Canceling is a useful function that automatically selects one
of the noise canceling modes. is function provides the most eective
noise canceling mode by immediately analyzing ambient sound
components when the AI NC button is pressed.
Press the AI NC button.
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 eective noise canceling mode is
set automatically, and sound reproduction from the headphones starts.

Noise canceling mode types
NC Mode A: Noise mainly in an airplane is eectively reduced.
NC Mode B: Noise mainly in a bus or a train is eectively reduced.
NC Mode C: Noise mainly found in an oce environment (PC, copier,
air ventilation, etc.) is eectively reduced.
Tips
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.

Precautions
e headphones contain a noise canceling circuit.
What is noise canceling?
e noise canceling circuit actually senses outside noise with built-in
microphones and sends an equal-but-opposite canceling signal to the
headphones.
e noise canceling eect may not be pronounced in a very quiet
environment, or some noise may be heard.
e noise canceling eect 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.
Notes on usage
Clean the headphones with a so 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.
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.
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.
Do not use headphones while driving and cycling, etc.
As headphones reduce outside sounds, they may cause a trac
accident. Also, avoid listening with your headphones in situations
where hearing must not be impaired, for example, a railroad crossing, a
construction site, etc.
Note on static electricity
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.
e eect can be minimized by wearing clothes made from natural
materials.
If you have any questions or problems concerning the system that
are not covered in this manual, please consult the nearest Sony
dealer.
Troubleshooting
No sound
Replace the battery. You can use the headphones even without turning
on the power. In this case, the noise canceling function, Digital
Equalizer and S-Master are not active, and the headphones operate as
passive headphones.
Check the connection of the headphones and the AV equipment.
Check that the connected AV equipment is turned on.
Turn up the volume of the connected AV equipment.
Check if the MONITOR function is on (the indicator blinks slowly).
Press the MONITOR button to turn it o.
The noise canceling eect is not sucient
e noise canceling function is eective in low frequency ranges such
as airplanes, trains, or oces (near air-conditioning, etc.) and is not as
eective for higher frequencies, such as human voices.
Turn on the headphones.
Distorted sound
Turn down the volume of the connected AV equipment.
Power does not turn on
Check if the battery has expired (the POWER indicator lights o).
Replace the battery with a new one.
No operation works
Set the POWER switch of the headphones to “OFF”, conrm the
connections, and then set the POWER switch back to “ON”.
