Digital Equalizer and S-Master are not active, and the
headphones operate as passive headphones.
Installing the earbuds
If the earbuds do not t your ears correctly, the noise
canceling eect will not be optimal. To optimize noise
canceling and to enjoy better sound quality, change the
earbuds to another size, or adjust the earbuds position
to t your ears comfortably and snugly.
e M size earbuds are attached to the headphones
before shipment. If you feel the M size earbuds do not
suit your ears, replace them with the supplied S or L size
earbuds. Conrm the size of the earbuds by checking
color inside. When you change the earbuds, turn to

urethane cushion is broken or detached from the earbuds, it
will not take its correct position and the earbuds will lose their
noise isolation function.
e pressure-relieving urethane cushion may deteriorate due
to long-term storage or use. If the pressure-relieving power is
lost and the urethane cushion becomes hard, the earbuds may
lose their noise isolation function.
Do not wash the noise isolation earbuds. Keep them
dry, and avoid accumulation of water in the pressure-
relieving urethane-cushions. Not doing so may cause early
deterioration.
To detach an earbud
While holding the headphone, twist and pull the earbud

mode by immediately analyzing ambient sound
components when the AI NC button is pressed.
Press the AI NC button.
When you press the AI NC button and the POWER
switch is set to “ON”, beep sounds come from the
headphones to inform you that the unit has started
analyzing ambient sound components (approx. 3

When analysis is completed, the most eective noise
canceling mode is set automatically, and sound
reproduction from the headphones starts.

When carrying the headphones
e headphones and the control box can also be
separately stored in the partitioned carrying pouch
(supplied).
Pocket for

After use
Turn o the power of the headphones.
Precautions
e headphones contain a noise canceling circuit.
What is noise canceling?
e noise canceling circuit actually senses outside noise
with built-in microphones and sends an equal-but-
opposite canceling signal to the headphones.
e noise canceling eect may not be pronounced in a
very quiet environment, or some noise may be heard.
e noise canceling eect may vary depending on how
you wear the headphones.
e 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.
If headphone sound is noisy, move the control box
away from sources of interference, such as a radio, etc.
Notes on usage
Clean the headphones with a so dry cloth.
Do not leave the plug dirty otherwise the sound may
be distorted.
Be sure to consult a Sony dealer when the earbuds
become dirty or damaged, or when the headphones
require repair work.
Do not leave the stereo 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 these
headphones, stop use immediately.
Install the earbuds rmly onto the headphones. If an
earbud accidentally detaches and is le 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 trac 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. is is a result of static electricity accumulated in
the body, and not a malfunction of the headphones.
e eect 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.
