Replace the battery with a new one when the POWER indicator blinks

or lights off. Push the PUSH OPEN button to open the battery lid and

remove the battery in the direction as illustrated.

When connecting the cord, insert the plug into the jack until the green

portion of the plug disappears.

To disconnect the cord, pull it out by the plug, not the cord, as the inner

conductors may break.

 Turn on the power of the headphones.

 The POWER indicator lights up in green. When power is

turned on, ambient noise is reduced, and you can listen to

music more clearly at a lower volume.

POWER

 Wear the headphones marked  on your right ear and the

one marked  ( has a tactile dot for ease of use.) on your

left ear.

Adjust the earpads so that they cover your ears, otherwise noise canceling

will not function properly.

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.

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. This is not a malfunction.

 Turn on the power of the AV equipment.

The supplied plug adaptor can be connected to the dual or stereo mini

jacks of in-flight music services.

Do not use the headphones when use of electronic equipment is

prohibited or when use of personal headphones for in-flight music

services is prohibited.

AI Noise Canceling is a useful function that automatically selects one

of the noise canceling modes. This function provides the most effective

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 effective noise canceling mode is

set automatically, and sound reproduction from the headphones starts.

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.

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.

Creation of a high-precision canceling signal delivers outstanding

noise canceling performance.

Select AI NC button for optimal noise canceling mode based on

intelligent analysis of the environmental ambient noise.

Rotate the housings to make them flat for easy storage in the seat pocket.

Restore to their usual position before using.

Fold the headphones as illustrated before putting them in the carrying case

(supplied).

The headphones contain a noise canceling circuit.

The noise canceling circuit actually senses outside noise with built-in

microphones and sends an equal-but-opposite canceling signal to the

headphones.

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

headphones.

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 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.

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 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.

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 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.

In particularly dry air conditions, noise or sound skipping may occur,

or mild tingling may be felt on your ears. This is a result of static

electricity accumulated in the body, and not a malfunction of the

headphones.

The effect 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.

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 off.

The noise canceling function is effective in low frequency ranges such

as airplanes, trains, or offices (near air-conditioning, etc.) and is not as

effective for higher frequencies, such as human voices.

Turn on the headphones.

Turn down the volume of the connected AV equipment.

Check if the battery has expired (the POWER indicator lights off).

Replace the battery with a new one.

Set the POWER switch of the headphones to “OFF”, confirm the

connections, and then set the POWER switch back to “ON”.
