GENERAL

2

Wear the headphones marked R in your right
ear and the one marked L in your left ear. Push
the earbud into your ear carefully so that the
earbud fits the hole of your ear snugly.

Note

Unless the headphones correctly fit your ears, noise
canceling will not function.
Adjust the earbuds position to sit on your ear comfortably,
and push them into the inside of your ears so that they fit
your ears snugly.

Using the clip

You can fasten the battery box by its clip on a shirt pocket.

Insert one R03 (size AAA) battery by matching
the + and − on the battery to the + and − in the
battery box.

Insert the # end first.

Selecting the
earbuds

The M size earbuds are attached to the headphones before
shipment. If you feel the M size earbuds do not suit your
ears, replace them with the supplied S or L size earbuds.

Listening to music

Connect the headphones to the AV equipment.

Turn on the power of the headphones.
The power indicator lights in red. The power
switch is located on the battery box. When
power is turned on, ambient noise is reduced,
and you can listen to music more clearly at a
lower volume.

4

Turn on the power of the AV equipment.

5

Adjust the volume.
Turn the VOL control.
(If you turn down the volume, the sound does
not mute completely.)

Corporation.

Notes on using on the airplane

•

The supplied plug adaptor can be connected to dual and
stereo mini jacks.

•

Do not use the headphones when use of electronic
equipment is prohibited or when use of personal
headphones for inflight music services is prohibited.

If you have any questions or problems concerning the
system that are not covered in this manual, please consult
the nearest Sony dealer.

After listening to music

Turn off the power of the headphones.

Notes

• The noise canceling function is only effective for noise in the

low frequency band. Although noise is reduced, it is not
canceled completely.

• Do not cover the microphone of the headphones with your

hands. The noise canceling function may not work properly.

• The noise canceling function may not work properly unless

the headphones are put on firmly.

• You can use the headphones even without turning on the

power. In this case, the noise canceling function is not active,
and the headphones operate as passive headphones.

• 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.

• In a quiet place, or depending on certain noises, you may feel

that the noise canceling function is not effective, or that noise
is accentuated. In this case, turn off the power of the
headphone.

• Interference noise can occur from nearby cellular phones.

Should this occur, locate the headphones further away from
the cellular phone(s).

When carrying the headphones

You can attach the headphones to the supplied holder to
keep them together. The headphones and the battery box
can also be separately stored in the partitioned carrying case
(supplied).

Holder

While using the headphones, you can attach the holder to
the headphone cord.

Precautions

•

Clean the headphones with a soft dry cloth.

•

Do not leave the jackplug dirty otherwise the sound may
be distorted.

•

Be sure to bring the headphones to the Sony dealer when
requiring a change of earbuds or repair work.

•

The CE mark on the unit is valid only for products
marketed in the European Union.

•

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.

•

To clean the earbuds, first remove them from the
headphones, and then clean them with water and mild
detergent. After cleaning, dry each earbud carefully
before use.

•

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.

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
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.

Features

•

Noise canceling headphones reduce ambient noise, and
provide a quieter environment to enhance audio
entertainment. Ambient sound is synthesized with an
anti-sound signal produced by the noise canceling circuit,
and reduced.

•

Ultra compact earphones with 9mm driver unit fits
comfortably in the ear and closed type earphone structure
delivers deep bass sound.

•

Soft silicon rubber earbuds are used for stable and
comfortable fit in the ears.

•

Volume control function for easy connecting to your
portable audio player.

•

New earphone holder minimizes cord tangles during
strage.

•

Operates as passive headphones when noise canceling
circuit is not activated.

•

Plug adaptor is supplied to connect directly to stereo or
dual jack of inflight music services.

amplifier

–

Procedure:

1. Generate a sine wave of specific frequency (250 Hz) from a
AF oscillator, and output it from a speaker placed at the forward
position.

2. Mount this headphones on the ear, and turn on the [POWER]
switch.

3. With this headphones mounted, adjust the RV1 (L-ch) and
RV51 (R-ch) so that the volume from the speaker becomes
lowest aurally.

Note:

When the headphones are not covered with the ear pieces completely, the
adjustment may not be performed correctly.
Make sure that the ear pieces cover the headphone completely.
