Tips

If you start charging while the headphones are turned on, the

headphones will turn off automatically.

The headphones cannot be turned on while charging.

If you recharge the headphones by connecting to an AC outlet, use the

separately-sold USB Charging AC Power Adaptor AC-U501AD / Built-in

Battery USB AC Charger AC-UP100 (see “Recommended accessories”).

For more information, refer to the operating instructions supplied with

the adaptor.

If the headphones are malfunctioning, charging will not start and the

charging indicator will flash. In this case, disconnect the unit from the

connected device, and consult your place of purchase, or a Sony dealer.

Notes

Charge in an environmental temperature of between 0°C and 40°C (32°F

and 104°F). Otherwise, the battery may not fully charge.

Take the headphones off before charging.

When unplugging the headphones, hold the cord by the plug. Do not pull

on the cord or it may break.

If you haven’t used the headphones for a long time, the life of the

rechargeable battery may become short. This will improve when you

repeat the charging and discharging process several times.

Do not store the headphones in hot places for a long time. When storing

it for more than a year, charge the battery once a year to prevent over

discharge.

For system requirements for a computer that can charge the battery using

USB, see “System requirements for battery charge using USB”.

Charging will not start if the extension cord is used. Connect the

headphone plug to the USB charge adaptor directly.

How to install the earbuds

correctly (see fig. )

If the earbuds do not fit your ears correctly, the noise

canceling effect will not be optimal. To optimize noise

canceling and to enjoy better sound quality, change the

earbuds to another size, or adjust the earbud position to fit

your ears comfortably and snugly.

If the earbuds do not fit your ears, try another size. Confirm

the size of the earbuds by checking Colored inside (see fig.

-).

If you change the earbuds, install them firmly on the

headphones to prevent the earbud from detaching and

remaining in your ear.

To detach an earbud (see fig. -)

While holding the headphone, twist and pull the earbud off.
Tip

If the earbud slips and cannot be detached, wrap it in a soft

dry cloth.

To attach an earbud (see fig. -)

Push the parts inside of the earbud into the headphone until

the projecting part of the headphone is fully covered.
Notes

Prolonged use of the noise isolation earbuds may strain your ears due to

their snug fit. If you experience discomfort in your ears, it is

recommended to stop using the earbuds for a while.

The pressure-relieving urethane cushion is extremely soft. Therefore, do

not pinch or pull the urethane cushion. If the urethane cushion is broken

or detached from the earbuds, it will not take its correct position and the

earbuds will lose their noise isolation function.

The pressure-relieving urethane cushion may deteriorate due to long-

term storage or use. If the pressure-relieving power is lost and the

urethane cushion becomes hard, the earbuds may lose their noise

isolation function.

Do not wash the noise isolation earbuds. Keep them dry, and avoid

accumulation of water in the pressure-relieving urethane cushions. Not

doing so may cause early deterioration.

Listening to music (see fig. )

1

Connect the headphones to the A/V equipment.

2

Put on the headphones.

Wear the earpiece marked  in your right ear and the

one marked  ( has a tactile dot for easy recognition)

in your left ear.

Adjust the earbud position to fit your ears snugly.
Note

If you wear the headphones incorrectly, noise canceling

will not be effective. Adjust the earbud position to sit on

your ears comfortably and fit your ears snugly.

3

Press and hold the (power) button for about 2
seconds.

You can check the remaining battery charge, by the number

of beeps when you turn the headphones off. For details, refer

to “Beep and indicator status”.

When the battery becomes empty, beeps sound from the

headphones for 2 seconds and the power indicator flashes

for 30 seconds. Then the headphones will turn off

automatically.

Automatic AI Noise Canceling

Automatic AI Noise Canceling is a function that

automatically selects one of the noise canceling modes.

When the headphones are turned on, NC mode B is set.

This function provides very effective automatic noise

canceling by constantly analyzing ambient sound.

Noise canceling modes

The current noise canceling mode can be checked by the

number of power indicator flashes. For details, refer to

“Beep and indicator status”.

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.
Tip

Noise characteristics vary over time.

The headphones automatically select the appropriate noise canceling

mode for the situation.

How to use the supplied cord adjuster

(see fig. )

You can adjust the cord length by winding the cord onto the

cord adjuster.

Precautions

The headphones contain a noise canceling circuit.

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.

 The noise canceling effect may not be pronounced in a

very quiet environment, or some noise may be heard.

 Do not cover the microphones of the headphones with

your hands. The noise canceling function may not work

properly.

 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.

Notes on usage

 Clean the headphones with a soft dry cloth.

 Do not leave the jack plug dirty otherwise the sound may

be distorted.

 Be sure to bring the headphones to a Sony dealer when

requiring a change of earbuds or 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.

 The earbuds will need to be replaced from time to time. If

they are worn out by daily use or longtime storage, replace

them with new ones.

 If you fell drowsy or sick while using these headphones,

stop use immediately.

 The headphones are designed to fit closely in your ears. If

the headphones are pressed hard while in use, they may

damage your eardrum or elsewhere. Do not use the

headphones in a crowd or a place where a ball, etc., may

hit you.

 Install the earbuds firmly onto the headphones. If an

earbud accidentally detaches and is left in your ear, it may

cause injury.

 Store the earbuds where children cannot reach in order to

prevent from accidental ingestion or choking.

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 or 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.

Note on static electricity

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

your nearest Sony dealer.
