the headphones in one of the following ways:
• Connect the headphones to the AC power adaptor by
following the steps shown in “Charge the
headphones.”
You can use the headphones while charging.
• Use the supplied connecting cord with battery case.
See “How to use the connecting cord with battery
case” for details.

Listening to music
1 Connect the headphones to the AV
equipment.
* “WALKMAN” and “WALKMAN” logo are
registered trademarks of Sony Corporation.
Notes
• 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.
2 Turn on the power on the right side of the
headphones.
The POWER indicator lights up in blue, and a
short beep sounds from the unit.
3 Put on the headphones.
After confirming the cord on the left and the
POWER switch on the right, put on the
headphones.
Adjust the ear pads so as to cover your ears.
5 Set the POWER switch of the
headphones to “OFF,” and then set the
POWER switch of the battery case to
“ON.”
The POWER indicator on the battery case
lights up green.
See steps 2 to 4 of “Listening to music” for
the following setting steps.
After use, set the POWER switch of both the
headphones and the battery case to “OFF.”
z Tips
• The power supply of the rechargeable battery is
consumed first, unless the battery runs out.
• If you connect and turn on the connecting cord with
battery case in advance when the rechargeable battery
is low, you can use the headphones uninterrupted,
even after the battery in the headphones runs out.
Notes
• The use of manganese batteries is not recommended,
since this type of battery has an extremely short
usage time.
• The battery case supplies the power to the
headphones for operation purposes only. It does not
charge the internal rechargeable battery in the
headphones.
• The POWER indicator of the battery case becomes
dim when the battery life is reaching the limit.
Replace the battery with new ones at the time.
• The supplied connecting cord with battery case is
only for these headphones. Do not connect to other
equipment.

Notes
• Use the AC power adaptor supplied with this unit. Do
not use any other AC power adaptor since it may
cause the unit to malfunction.
Polarity of the plug
• Avoid exposure to temperature extremes, direct
sunlight, moisture, sand, dust or mechanical shock.
Never leave in a car parked in the sun.
• Charge in an environmental temperature of between
0°C and 40°C (between 32°F and 104°F). Otherwise,
the battery may not be fully charged.
• If you haven’t used the headphones for a long period
of time, the life of the rechargeable battery may
become short. This will improve when you repeat the
charging and discharging process several times.
• When the battery life reduces to half, this may be the
end of battery lifetime. For how to change batteries,
consult your place of purchase or a Sony dealer.
• Do not store the headphones in hot places for a long
period of time. When storing it for more than a year,
charge the battery once a year to prevent over
discharge.
• You cannot charge the rechargeable battery using the
supplied connecting cord with battery case.

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.
• 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.
• Howling may occur if you do not wear the
headphones correctly.
• Howling may occur if you place an object such
as finger close to inside of the headphones.
Keep it away from the headphones.
•Mobile phones may cause interference and
noise. To avoid interference, use noise
canceling feature only with wireless
transmitters turned off (Airplane Mode).
Interference noise can also occur from nearby
mobile phones. 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 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.
