Precautions

On BLUETOOTH® communications

• 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.

• Bluetooth communications may be disabled, or noise or audio

dropout may occur under the following conditions.

– 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.

– There is an obstacle, such as metal or a wall, between the unit

and the Bluetooth device.

– A Wi-Fi device or microwave oven is in use, or microwaves are

emitted near the unit.

– The antenna is built into the unit as illustrated in the dotted line.

The sensitivity of the Bluetooth communications will improve by

removing any obstacles between the connected Bluetooth

device and the antenna of this unit.

• 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.

– Use this unit at least 10m (30feet) away from the Wi-Fi device.

– If this unit is used within 10m (30feet) of a Wi-Fi device, turn

off the Wi-Fi device.

– Install this unit and the Bluetooth device as near to each other

as possible.

• 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:

– where inflammable gas is present, in a hospital, or a petrol

station

– near automatic doors or a fire alarm.

• Due to the characteristic of the wireless technology, the sound

played on this unit is delayed from the sound and music played

on the sending device. Therefore, the image and sound may be

misaligned when viewing a movie or playing a game.

• This product emits radio waves when used in wireless mode.

When used in wireless mode on an airplane, follow flight crew

directions regarding permissible use of products in wireless

mode.

• 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.

• We do not take any responsibility for the leakage of information

during Bluetooth communications.

• Connection with all Bluetooth devices cannot be guaranteed.

– A device featuring Bluetooth function is required to conform to

the Bluetooth standard specified by Bluetooth SIG, Inc. and be

authenticated.

– Even if the connected device conforms to the above

mentioned Bluetooth standard, some devices may not be

connected or work correctly, depending on the features or

specifications of the device.

– While talking on the phone hands free, noise may occur,

depending on the device or communication environment.

• Depending on the device to be connected, it may require some

time to start communications.

If sound skips frequently during playback

• The situation may be improved by setting the sound quality

mode to “priority on stable connection.” For details, refer to the

Help Guide.

• The situation may be improved by changing the wireless

playback quality settings or fixing the wireless playback mode to

SBC on the transmitting device. For details, refer to the operating

instructions supplied with the transmitting device.

• If you are using a smartphone, the situation may be improved by

shutting down unnecessary applications or rebooting the

smartphone.

On the use of calling apps for smartphones and computers

• This unit supports normal incoming calls only. Calling apps for

smartphones and computers are not supported.

On charging the unit

• This unit can be charged using USB only. Personal computer with

USB port is required for charging.

• When charging, the unit cannot be turned on and the Bluetooth

and noise canceling functions cannot be used.

• You can use the unit by connecting the supplied headphone

cable, even while charging the unit.

• 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.

• If you store the unit for a long time, charge the battery once

every half year to prevent over-discharge.

• 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

• 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

• Reset the unit.

Press the  and NC buttons simultaneously while charging. The

unit will be reset. Pairing information is not deleted.



• If the problem persists even after the resetting operation above,

initialize the unit as follows.

Disconnect the micro-USB cable from the micro-USB port, turn

off the unit, then hold down the  and  buttons

simultaneously 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.

• 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?

• The noise canceling circuit actually senses outside noise with

built-in microphones and sends an equal-but-opposite canceling

signal to the unit.

– The noise canceling effect may not be pronounced in a very

quiet environment, or some noise may be heard.

– The noise canceling effect may vary depending on how you

wear the unit.

– 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 unit 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 unit further away from the mobile phone.

– Do not cover the microphones of the headset (Microphones)

with your hands. The noise canceling function may not work

properly.

Microphones

On wearing the unit

• Because the headphones are of a high density enclosure, forcing

them against your ears may result in eardrum damage.

Pressing the headphones against your ears may produce a

diaphragm click sound. This is not a malfunction.

Others

• When you use the unit as wired headphones, use the supplied

headphone cable only. Make sure that the headphone cable is

firmly inserted.

• Do not place this unit in a place exposed to humidity, dust, soot

or steam, or in a car or place subject to direct sunlight.

• Using the Bluetooth device may not function on mobile phones,

depending on radio wave conditions and location where the

equipment is being used.

• High volume may affect your hearing.

• For traffic safety, do not use while driving or cycling.

• 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.

• Do not put weight or pressure on this unit as it may cause the

unit to deform during long storage.

• Do not subject the unit to excessive shock.

• Clean the unit with a soft dry cloth.

• Do not expose the unit to water. The unit is not waterproof.

Remember to follow the precautions below.

– Be careful not to drop the unit into a sink or other container

filled with water.

– Do not use the unit in humid locations or bad weather, such as

in the rain or snow.

– 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.

• If you experience discomfort after using the unit, stop using the

unit immediately.

• The earpads may deteriorate due to long term storage or use.

• If you have any questions or problems concerning this unit that
