English
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
headphones.
• Interference noise can occur from nearby cellular phones.
Should this occur, locate the headphones further away from
the cellular phone(s).
Using the clip
You can fasten the battery box by its clip on a shirt pocket.
When carrying the headphones
The headphones and the battery box can also be separately
stored in the partitioned carrying case (supplied).
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, 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.
• Install the earbuds firmly 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
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, 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.
• Replace the battery.
Muffled sound
• Turn down the volume of the connected AV equipment.
• Replace the battery.
