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