modifications not expressly approved in this
manual could void your authority to operate

enforced, mainly in the countries EEA (European
Economic Area).

accept any interference received, including
interference that may cause undesired

Notes on use
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.
Notes on the noise canceling function
Adjust the earpads so that they cover your
ears, otherwise noise canceling will not
function properly.
The noise canceling effect may vary
depending on how you wear the headphones.
Do not cover the microphone of the
headphones with your hands. The noise
canceling function may not work properly.
Microphone
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.
The noise canceling function works for noise
in the low frequency band primarily. Although
noise is reduced, it is not canceled completely.
The noise canceling effect may not be
pronounced in a very quiet environment, or
some noise may be heard.
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 using on the airplane
Do not use the headphones when use of
electronic equipment is prohibited or when
use of personal headphones for in-flight
entertainment services is prohibited.
Notes on handling
Because the headphones are designed to fit
closely in your ears, forcing them against your
ears may result in eardrum damage. Avoid
using the headphones where they are liable
to be struck by people or other objects, such
as a ball, etc.
Pressing the headphones against your ears
may produce a diaphragm click sound. This is
not a malfunction.
Clean the headphones with a soft dry cloth.
Do not leave the plug dirty otherwise the
sound may be distorted.

OPEN
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 headphones in a location
subject to direct sunlight, heat or moisture.
Do not subject the headphones to excessive
shock.
Handle the driver units carefully.
If you feel drowsy or sick while using this
headphones, stop use immediately.
Notes on headphones
High volume may affect your
hearing. For traffic safety, do not
use while driving or cycling.
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, noise or sound
skipping may occur, or 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 the nearest
Sony dealer.
Troubleshooting
No sound
Check the connection of the headphones and
the equipment.
Check that the connected equipment is
turned on.
Turn up the volume of the connected
equipment.
The noise canceling effect is not sufficient
The noise canceling function is effective in low
frequency ranges such as airplanes, trains, or
offices (near air-conditioning, etc.) and is not
as effective for higher frequencies, such as
human voices.
Turn on the headphones.
Distorted sound
Turn down the volume of the connected
equipment.
Power does not turn on
Check if the battery has expired (the POWER
indicator lights off) and the battery is inserted
in the correct orientation. Replace the battery
with a new one or reinsert the battery in the
correct orientation.
