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
headpho
n
es.
• The noise cance
li
ng effect may not
be
p
ronounced
in a
ve
ry 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. A
lt
hough
noise is reduced,
it
is not canceled
completely.
• Wh
en
you use the
headphones
in a train or a car, noise may
occur
depending
on
street conditions.
• Mob
il
e phones may cause interference
and
noise. Should this occu
r,
locate the headphones further away from the
mo
bile
phone
.
Notes
on
usage
o Clean the
headphones
wi
th a soft
dry
doth.
• Do not leave the plug
dirty
otherwise t
he
sound
may
be
distorted.
•

sure
to
consult a Sony dealer when the
ear
pads become
dirty
or
damaged,
or
when t
he
headphones
require repair work.
• Do not leave the stereo
headphones
in a locati
on
subject
to
dire<:t
sunlight, heat
or
moisture.
o Do not subject the
headpho
nes
to
excessive shock.
o Handle the driver units carefully.
• If you
feel
drowsy
or
~ick
while using these
headp
hones, stop use
immediatel
y.
Notes

loud
and
extended play. If you experience a ringing
in your ears, reduce the volume
or
discontinue

reduce outside sounds, they may cause a traffic
accident. Also, avoid listening with
your

where hearing must not be impaired, for example, a railroad crossing, a
construction site, etc.

tions, noise
or
sound
skipping
may
occur,
or
