The available scientific evidence does not show that any health

problems are associated with using low power wireless devices. There

is no proof, however, that these low power wireless devices are

absolutely safe. Low power Wireless devices emit low levels of radio

frequency energy (RF) in the microwave range while being used.

Whereas high levels of RF can produce health effects (by heating

tissue), exposure of low-level RF that does not produce heating

effects causes no known adverse health effects. Many studies of

low-level RF exposures have not found any biological effects. Some

studies have suggested that some biological effects might occur, but

such findings have not been confirmed by additional research.

Precautions

On BLUETOOTH® communications

• Bluetooth wireless technology operates within a range of about 10 m

(30 feet). The maximum communication distance may vary depending

on the presence of obstacles (people, metal objects, walls, etc.) or the

electromagnetic environment.

• Bluetooth communications may not be possible, or noise or audio

dropout may occur under the following conditions:

– When there is a person between the unit and the Bluetooth device.

This situation may be improved by positioning the Bluetooth device

so that it faces the antenna of the unit.

– When there is an obstacle, such as a metal object or a wall, between

the unit and the Bluetooth device.

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

emitted near the unit.

– Compared to use indoors, use outdoors is subjected little to signal

reflection from walls, floors, and ceilings, which results in audio

dropout occurring more frequently than use indoors.

– The antenna is built into the unit as indicated by the dotted line in the

illustration below. The sensitivity of the Bluetooth communications

can be improved by removing any obstacles between the connected

Bluetooth device and the antenna of this unit.

• Bluetooth and Wi-Fi (IEEE802.11b/g/n) devices use the same frequency

(2.4 GHz). When using the unit near a Wi-Fi device, electromagnetic

interference may occur, resulting in noise, audio dropout, or the

inability to connect. If this happens, try performing the following

remedies:

– Establish a connection between the unit and the Bluetooth device

when they are at least 10 m (30 feet) away from the Wi-Fi device.

– Turn off the Wi-Fi device when using the unit within 10 m (30 feet) of

the Wi-Fi device.

– Position the unit and the Bluetooth device as near as possible to each

other.

• 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:

– in hospitals, near priority seating in trains, locations where

inflammable gas is present, near automatic doors, or near fire alarms.

• The audio playback on this unit may be delayed from that on the

transmitting device, due to the characteristics of Bluetooth wireless

technology. As a result, the sound may not be in sync with the image

when viewing movies or playing games.

• 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.

• The unit supports security functions that comply with the Bluetooth

standard as a means of ensuring security during communication using

Bluetooth wireless technology. However, depending on the configured

settings and other factors, this security may not be sufficient. Be careful

when communicating using Bluetooth wireless technology.

• Sony shall assume no responsibility for any damages or loss resulting

from information leaks that occur when using Bluetooth

communications.

• Connection with all Bluetooth devices cannot be guaranteed.

– Bluetooth devices connected with the unit must comply with the

Bluetooth standard prescribed by Bluetooth SIG, Inc., and must be

certified as compliant.

– Even when a connected device complies with the Bluetooth standard,

there may be cases where the characteristics or specifications of the

Bluetooth device make it unable to connect, or result in different

control methods, display, or operation.

– When using the unit to perform hands-free talking on the phone,

noise may occur depending on the connected device or the

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.

• When listening to music from a smartphone, the situation may be

improved by closing unnecessary apps or restarting 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. A computer with a USB port or

a USB AC adaptor is required for charging.

• Be sure to use the supplied USB Type-C cable.

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

noise canceling functions cannot be used.

• If the unit is not used for a long time, the rechargeable battery may

become depleted quickly. The battery will be able to hold a proper

charge after it is discharged and recharged several times. When storing

the unit for a long time, charge the battery once every six months to

prevent over-discharge.

• If the rechargeable battery becomes depleted extremely quickly, it

should be replaced with a new one. Please contact your nearest Sony

dealer for a battery replacement.

CUSTOM



• If the problem persists even after the unit is reset, perform the

procedure below to initialize the unit.

Disconnect the USB Type-C cable and turn off the unit. Press and hold

the  and CUSTOM buttons simultaneously for at least 7 seconds. The

indicator (blue) flashes 4 times, the unit is initialized, and the unit is

reset to the factory settings. When the unit is initialized, all pairing

information is deleted.

• After the unit is initialized, it may not connect to your iPhone or

computer. If this happens, delete the pairing information of the unit

from the iPhone or computer, and then pair them again.

On the noise canceling function

• The noise canceling function senses external ambient noise (such as

the noise inside a vehicle or the sound of air conditioning inside a

room) with built-in microphones, and produces an equal-but-opposite

sound that cancels out the ambient noise.

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

environment, or some noise may be heard.

– 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.

– Depending on how you wear the unit, the noise canceling effect may

vary or a beeping sound (howling) may occur. If this happens, take off

the unit and put it back on again.

– Do not cover the microphones of the unit with your hands or other

objects. Doing so may prevent the noise canceling function or the

Ambient Sound Mode from working properly, or may cause a beeping

sound (howling) to occur. If this happens, take your hands or other

object off of the microphones of the unit.

Notes on wearing the unit

• Because the headphones achieve a tight seal over the ears, forcibly

pressing them against your ears or quickly pulling them off can result in

eardrum damage. When wearing the headphones, the speaker

diaphragm may produce a click sound. This is not a malfunction.

Other notes

• Do not subject the unit to excessive shock.

• The touch sensor may not operate properly if you apply stickers or

other adhesive items to the touch sensor control panel.

• Be careful not to catch your finger in the unit when folding.

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

headphone cable only. Make sure that the headphone cable is firmly

inserted.

• The Bluetooth function may not work with a mobile phone, depending

on the signal conditions and the surrounding environment.

• Do not apply weight or pressure to the unit for long periods, including

when it is stored, as it may cause deformation.

• If you experience discomfort while using the unit, stop using it

immediately.

• The earpads may be damaged or deteriorate with long-term use and

storage.

Cleaning the unit

• When the outside of the unit is dirty, clean it by wiping with a soft dry

cloth. If the unit is particularly dirty, soak a cloth in a dilute solution of

neutral detergent, and wring it well before wiping. Do not use solvents

such as thinner, benzene, or alcohol, as they may damage the surface.

Pour la clientèle au Canada

L’émetteur/récepteur exempt de licence contenu dans le présent

appareil est conforme aux CNR d’Innovation, Sciences et

Développement économique Canada applicables aux deux

conditions suivantes :

1) l’appareil ne doit pas produire de brouillage;

2) l’utilisateur de l’appareil doit accepter tout brouillage

radioélectrique subi, même si le brouillage est susceptible d’en

compromettre le fonctionnement

Les connaissances scientifiques dont nous disposons n’ont mis en

évidence aucun problème de santé associé à l’usage des appareils

sans fil à faible puissance. Nous ne sommes cependant pas en

mesure de prouver que ces appareils sans fil à faible puissance sont

entièrement sans danger. Les appareils sans fil à faible puissance

émettent une énergie fréquence radioélectrique (RF) très faible dans

le spectre des micro-ondes lorsqu’ils sont utilisés. Alors qu’une dose

élevée de RF peut avoir des effets sur la santé (en chauffant les

tissus), l’exposition à de faibles RF qui ne produisent pas de chaleur

n’a pas de mauvais effets connus sur la santé. De nombreuses études

ont été menées sur les expositions aux RF faibles et n’ont découvert

aucun effet biologique. Certaines études ont suggéré qu’il pouvait y

avoir certains effets biologiques, mais ces résultats n’ont pas été

confirmés par des recherches supplémentaires. Casque stéréo sans fil

réducteur de bruits (WH-1000XM4) a été testé et jugé conforme aux

limites d’exposition aux rayonnements ISDE énoncées pour un

environnement non contrôlé et respecte les règles d’exposition aux

fréquences radioélectriques (RF) CNR-102 de l’ISDE.

Précautions

À propos des communications BLUETOOTH®

• La technologie sans fil Bluetooth fonctionne dans un rayon d’environ

10m (30 pieds). La distance maximale de communication peut varier en

fonction de la présence d’obstacles (personnes, objets métalliques,

murs, etc.) ou de l’environnement électromagnétique.

• Les communications Bluetooth peuvent ne pas être possibles ou du

bruit ou des pertes sonores peuvent se produire dans les conditions

suivantes:

– Lorsqu’il y a une personne entre l’appareil et le périphérique

Bluetooth. Cette situation peut être améliorée en plaçant le

périphérique Bluetooth de manière à ce qu’il soit face à l’antenne de

l’appareil.

– Lorsqu’il y a un obstacle, tel qu’un objet métallique ou un mur, entre

l’appareil et le périphérique Bluetooth.

– Lorsqu’un périphérique Wi-Fi ou un four à micro-ondes est en cours

d’utilisation ou que des micro-ondes sont émises à proximité de

l’appareil.

– Comparativement à une utilisation intérieure, l’utilisation extérieure

est peu soumise à la réflexion du signal sur les murs, les sols et les

plafonds, ce qui entraîne une perte sonore plus fréquente que lors de

l’utilisation à l’intérieur.

– L’antenne est intégrée à l’appareil comme l’indique la ligne en

pointillé sur l’illustration ci-dessous. La sensibilité des

communications Bluetooth peut être améliorée en retirant tout

obstacle entre le périphérique Bluetooth connecté et l’antenne de cet

appareil.
