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 headphones.
• Interference noise can occur from nearby cellular
phones. Should this occur, locate the headphones
further away from the cellular phone(s).

m
2 Insert one R03 (size AAA) battery in the
battery compartment. Observe the correct
polarity when installing battery.
Insert the E end
fi rst.
3 Align the battery lid with the control box
correctly, then slide to close the battery

Precautions
• 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 the 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.
• Handle the driver units carefully.
• To clean the earbuds, fi rst 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.
• Install the earbuds fi rmly onto the headphones. If
an earbud accidentally detaches and is left in your
ear, it may cause injury.
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 traffi 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, 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.
Troubleshooting
No sound
• 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.
Power does not turn on
• Check if the battery has expired (the POWER
indicator lights off). Replace the battery with a new
one.
