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.

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.

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.
