WARNING
To reduce the risk of electrical shock, do not open the
cabinet. Refer servicing to qualified personnel only.
IMPORTANT SAFETY
INSTRUCTIONS – SAVE
THESE INSTRUCTIONS.
DANGER – TO REDUCE THE
RISK OF FIRE OR ELECTRIC
SHOCK, CAREFULLY
FOLLOW THESE
INSTRUCTIONS.
For connection to a supply not in the U.S.A., use an attachment
plug adaptor of the proper configuration for the power outlet, if
needed.
To reduce the risk of fire or electric shock, do not expose
the AC adaptor to rain or moisture.
To reduce the risk of fire or electric shock, do not expose the AC
adaptor to dripping or splashing, and do not place objects filled
with liquids, such as vases, on the AC adaptor.
Do not install the appliance in a confined space, such as a
bookcase or built-in cabinet.
Do not expose the batteries (battery pack or batteries installed)
to excessive heat such as sunshine, fire or the like for a long
time.
As the main plug of USB AC adaptor is used to disconnect the
USB AC adaptor from the mains, connect it to an easily
accessible AC outlet. Should you notice an abnormality in it,
disconnect it from the AC outlet immediately.
The unit is not disconnected from the AC power source (mains)
as long as it is connected to the wall outlet, even if the unit
itself has been turned off.

Precautions
On BLUETOOTH communications
ˎ BlUETOOTH wireless technology operates within a range of
about 10 m (30 feet). Maximum communication range may
vary depending on obstacles (human body, metal, wall, etc.)
or electromagnetic environment.
ˎ The antenna is built into the unit as illustrated in the dotted
line. The sensitivity of the BlUETOOTH communications will
improve by turning the direction of the built-in antenna to
the connected BlUETOOTH device. When obstacles are
between the antenna of the connected device and the
built-in antenna of this unit, noise or audio dropout may
occur, or communications may be disabled.
ˎ BlUETOOTH communications may be disabled, or noise or
audio dropout may occur under the following conditions.
ē There is a human body between the unit and the
BlUETOOTH device.
This situation may be improved by placing the BlUETOOTH
device facing the antenna of the unit.
ē There is an obstacle, such as metal or wall, between the
unit and the BlUETOOTH device.
ē A device using 2.4 GHz frequency, such as a Wi-Fi device,
cordless telephone, or microwave oven, is in use near this
unit.
ˎ Because BlUETOOTH devices and Wi-Fi (IEEE802.11b/g/n) use
the same frequency (2.4 GHz), microwave interference may
occur resulting in noise or audio dropout or communications
being disabled if this unit is used near a Wi-Fi device. In such
a case, perform the following.
ē Use this unit at least 10 m (30 feet) away from the Wi-Fi
device.
ē If this unit is used within 10 m (30 feet) of a Wi-Fi device,
turn off the Wi-Fi device.
ē Install this unit and the BlUETOOTH device as near to each
other as possible.
ˎ Microwaves emitting from a BlUETOOTH device may affect
the operation of electronic medical devices. Turn off this unit
and other BlUETOOTH devices in the following locations, as it
may cause an accident:
ē where inflammable gas is present, in a hospital, or a petrol
station
ē near automatic doors or a fire alarm
ˎ Do not use the unit on an airplane. Radio waves may affect
instruments, causing an accident due to malfunction.
ˎ This unit supports security capabilities that comply with the
BlUETOOTH standard to provide a secure connection when
the BlUETOOTH wireless technology is used, but security may
not be enough depending on the setting. Be careful when
communicating using BlUETOOTH wireless technology.
ˎ We do not take any responsibility for the leakage of
information during BlUETOOTH communications.
ˎ Connection with all BlUETOOTH devices cannot be
guaranteed.
ē A device featuring BlUETOOTH function is required to
US
conform to the BlUETOOTH standard specified by
Bluetooth SIG, Inc. and be authenticated.
ē Even if the connected device conforms to the above
FR
mentioned BlUETOOTH standard, some devices may not
be connected or work correctly, depending on the features
or specifications of the device.
ē While talking on the phone hands free, noise may occur,
depending on the device or communication environment.
ˎ Depending on the device to be connected, it may require
some time to start communications.
On charging the unit
ˎ This unit can be charged using USB only. Personal computer
with USB port, or supplied USB charger is required for
charging.
ˎ This unit cannot be turned on, nor can the BlUETOOTH and
noise canceling functions be used, during charging.
ˎ You can use the unit by connecting the supplied headphone
cable, even while charging the unit.
ˎ If you do not use the unit for a long time, the rechargeable
battery may not be able to keep sufficient charge. The
battery will be able to keep a charge properly after
repeatedly discharging and charging several times.
ˎ If you store the unit for a long time, charge the battery once
every half year to prevent over-discharge.
ˎ If the length of time you can use the unit became extremely
short, the rechargeable battery should be replaced with a
new one. Please contact your nearest Sony dealer for a
battery replacement.
Note on static electricity
ˎ Static electricity accumulated in the body may cause mild
tingling in your ears. To minimize the effect, wear clothes
made from natural materials.
If the unit does not operate properly
ˎ Reset the unit.
Push the RESET button with a pointed object, such as a pin,
until you feel a click. The unit will be reset. Pairing
information is not deleted.
ˎ If the problem persists even after the resetting operation
above, initialize the unit as follows.
Turn off the unit by pressing the POWER button for more than
2 seconds. Then, press and hold the POWER button and the
/ button together for more than 7 seconds. The
indicator (blue) flashes 4 times, and the unit is reset to the
factory settings. All pairing information is deleted.
ˎ After the unit is initialized, it may not connect to your iPhone
or computer. In this case, delete the pairing information of
the unit from the iPhone or computer, and then pair them
again.
What is noise canceling?
ˎ The noise canceling circuit actually senses outside noise with
built-in microphones and sends an equal-but-opposite
canceling signal to the unit.
ē The noise canceling effect may not be pronounced in a
very quiet environment, or some noise may be heard.
ē The noise canceling effect may vary depending on how you
wear the unit.
ē The noise canceling function works for noise in the low
frequency band primarily. Although noise is reduced, it is
not canceled completely.
ē When you use the unit in a train or a car, noise may occur
depending on street conditions.
ē Mobile phones may cause interference and noise. Should
this occur, locate the unit further away from the mobile
phone.
ē Do not cover the microphones of the headset (MIC) with
your hands. The noise canceling function may not work
properly.
MIC
Others
ˎ Do not place this unit in a place exposed to humidity, dust,
soot or steam, subject to direct sunlight, or in a car waiting at
a traffic signal. It may cause a malfunction.
ˎ Using the BlUETOOTH device may not function on mobile
phones, depending on radio wave conditions and location
where the equipment is being used.
ˎ If you experience discomfort after using the BlUETOOTH
device, stop using the BlUETOOTH device immediately.
Should any problem persist, consult your nearest Sony dealer.
ˎ listening with this unit at high volume may affect your
hearing. For traffic safety, do not use this unit while driving or
cycling.
ˎ Do not use the unit in places where it would be dangerous if
you are unable to hear ambient sound, such as at railroad
crossings, train station platforms, and construction sites.
ˎ Do not put weight or pressure on this unit as it may cause the
unit to deform during long storage.
ˎ Do not subject the unit to excessive shock.
ˎ Clean the unit with a soft dry cloth.

such as in the rain or snow.
ē Do not get the unit wet.
If you touch the unit with wet hands, or put the unit in a
damp article of clothing, the unit may get wet and this may
cause a malfunction of the unit.
ˎ The earpads may deteriorate due to longterm storage or use.
ˎ If you have any questions or problems concerning this unit
that are not covered in this manual, please consult your
