Checking the remaining battery charge

You can check the remaining battery charge of the rechargeable battery in the following ways.

To check using the power button

When you press the (power) button (A) while the headset is on, a voice guidance indicating the remaining battery
charge can be heard.

“Battery about XX %” (The “XX” value indicates the approximate remaining charge.)
“Battery fully charged”
The remaining battery charge indicated by the voice guidance may differ from the actual remaining charge in some
cases. Use it as a rough estimate.
The indicator (orange) also flashes for about 15 seconds if the remaining battery charge is 10% or lower when the
headset is turned on.

When the remaining charge becomes low

A warning beep sounds and the color of the operating indicator (blue) becomes orange. If you hear the voice guidance
say, “Low battery”, charge the headset as soon as possible.
When the battery becomes completely empty, a warning beep sounds, the voice guidance says, “Battery is empty”, and
the headset automatically turns off.

When you are using an iPhone or iPod touch

When the headset is connected to an iPhone or iPod touch over an HFP (Hands-free Profile) Bluetooth connection, an
icon (B) is shown on the iPhone or iPod touch screen that indicates the remaining battery charge of the headset.
C, D, E, and F are examples where the battery level is at 100%, 70%, 50%, and 10% or less (charging is required).

The remaining battery charge of the headset is also displayed on the widget of an iPhone or iPod touch running iOS 11 or
later.
For more details, refer to the operating instructions supplied with the iPhone or iPod touch.
27
The remaining charge which is displayed may differ from the actual remaining charge in some cases. Use it as a rough
estimate.

When you are using an Android™ smartphone (OS 8.1 or later)

When the headset is connected to an Android smartphone via an HFP Bluetooth connection, select [Settings] - [Device
connection] - [Bluetooth] to display the remaining battery charge of the headset in 10 different levels such as “100%”,
“70%”, “50%” or “10%” in the connected Bluetooth device column. The operation above is an example. For details, refer
to the operating instructions for the Android smartphone.
The remaining charge which is displayed may differ from the actual remaining charge in some cases. Use it as a rough
estimate.

Hint
You can also check the remaining battery charge of the headset with the “Sony | Headphones Connect” app. Android
smartphones and iPhone/iPod touch both support this app.

Note
If the headset and smartphone are not connected with HFP, the remaining battery charge will not be correctly displayed.

If you connect the headset to an iPhone/iPod touch or Android smartphone with “Media audio” (A2DP) only in a multipoint
connection, the remaining battery charge will not be displayed correctly.

The remaining battery charge may not be properly displayed immediately after a software update or if the headset has not been
used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining
battery charge.

Connecting the headset to 2 devices simultaneously (multipoint connection)

When [Connect to 2 devices simultaneously] is turned on with the “Sony | Headphones Connect” app, the headset can
connect to 2 devices via Bluetooth connections simultaneously, allowing you to do the following.

Waiting for an incoming call for 2 smartphones

You can listen to music played on one smartphone with the headset, wait for an incoming call for both smartphones,
and talk if an incoming call arrives.

Switching music playback between 2 devices

You can switch the music playback from one device to the other without performing a Bluetooth reconnection.

Connecting the headset to 2 devices via Bluetooth connections simultaneously

Before connecting, make sure that the “Sony | Headphones Connect” app is installed on one of the 2 devices.

1 Pair the headset with 2 devices, respectively.

2 Operate the device on which the “Sony | Headphones Connect” app is installed to establish a Bluetooth
connection with the headset.

3 Turn on [Connect to 2 devices simultaneously] with the “Sony | Headphones Connect” app.

4 Operate the second device to establish a Bluetooth connection with the headset.

70
When Bluetooth connections are established between 2 devices and the headset, another paired device can be
connected via Bluetooth connection.
If you try to make a Bluetooth connection with the headset by operating the third device, the Bluetooth connection with
the last device that played music will be maintained, and the Bluetooth connection with the other device will be
disconnected. Then a Bluetooth connection between the third device and the headset is established.

Music playback when the headset is connected to 2 devices via Bluetooth connections
When playing music by operating the headset, the music is played from the device that played last.
If you want to play music from the other device, stop playback on the device that is playing the music, and start
playback by operating the other device.
Even if you start playback by operating the second device while playing music on the first device, the music from the
first device will continue to be heard via the headset. In this state, if you stop playback on the first device, you can
listen to music from the second device via the headset.

Talking on the phone when the headset is connected to 2 devices via Bluetooth connections
When the headset is connected to 2 smartphones, etc. via Bluetooth connections simultaneously, both devices will be
in standby mode.
When an incoming call arrives to the first device, a ring tone is heard via the headset.
When an incoming call arrives to the second device while talking on the headset, a ring tone is heard via the second
device. If you finish the call on the first device, the ring tone from the second device will be heard via the headset.

Note
When [Connect to 2 devices simultaneously] is turned on with the “Sony | Headphones Connect” app, LDAC cannot be used. The
codec is automatically switched to the connection by AAC or SBC.

What is noise canceling?

The noise canceling function generates antiphase sound against outside surrounding noises (such as noises in vehicles
or noises from air conditioners indoors) to reduce the surrounding noises by canceling them out.

Note
Depending on the type of noise or if it is used in a very quiet environment, you may not feel the noise canceling effects, or you
may feel that some noise is increased.

When you are wearing the headset, depending on how you wear the headset, the noise canceling effects may be decreased or a
beeping sound (feedback) may be heard. In this case, take off the headset and put it on again.

The noise canceling function works primarily on noise in the low frequency band such as vehicles and air conditioning. While
noise is reduced, it is not completely canceled.

When you use the headset in a car or a bus, noise may occur depending on street conditions.

Mobile phones may cause interference and noise. Should this occur, move the headset further away from the mobile phone.

Do not cover the call microphone (A) on the left unit of the headset and the noise canceling function microphones (B) on the left
and right units of the headset with your hand, etc. If they are covered, the effect of the noise canceling or the Ambient Sound
Mode may not be obtained, or a beeping sound (feedback) may occur. If any of this is the case, remove your hands, etc. from the
left and right microphones.

For details on how to use the noise canceling function, refer to the following Related Topic.

Supported codecs

A codec is an “audio coding algorithm” used when transmitting sound wirelessly via a Bluetooth connection.
The headset supports the following 3 codecs for music playback via an A2DP connection: SBC, AAC, and LDAC.

SBC
This is an abbreviation for Subband Codec.
SBC is the standard audio coding technology used in Bluetooth devices.
All Bluetooth devices support SBC.

AAC
This is an abbreviation for Advanced Audio Coding.
AAC is mainly used in Apple products such as iPhone that can provide a higher sound quality than that of SBC.

LDAC
LDAC is an audio coding technology developed by Sony that enables the transmission of High-Resolution (Hi-Res)
Audio content, even over a Bluetooth connection.
Unlike other Bluetooth-compatible coding technologies such as SBC, it operates without any down-conversion of the
High-Resolution Audio content*.
It allows approximately 3 times more data** than those other technologies to be transmitted over a Bluetooth wireless
network with unprecedented sound quality, employing efficient coding and optimized packetization.

* excluding DSD format contents.

** in comparison with SBC when the bitrate of 990 kbps (96/48 kHz) or 909 kbps (88.2/44.1 kHz) is selected.

When music in one of the above codecs is transmitted from a connected device, the headset switches to that codec
automatically and plays back the music in the same codec.
If the connected device supports a codec of higher sound quality than SBC, you may need to set the device beforehand
to enjoy music with the desired codec from the supported codecs.
Refer to the operating instructions supplied with the device regarding setting the codec.

About the DSEE function

The DSEE function complements the high-range sound, which is often lost from compressed sound sources, in the

Sound sources compressed by streaming playback, MP3, Bluetooth transmission codec, etc. are played with natural and
expansive sound.
The DSEE function can be set up on the “Sony | Headphones Connect” app, and is only available when connected to the
headset via a Bluetooth connection.
Depending on the specifications of the playback device, the DSEE function may be disabled when transmitting a
compressed sound source using LDAC.

Note
When DSEE is set to [Auto], the available operating time is reduced.

Precautions

On Bluetooth communications
Bluetooth wireless technology is a short-range wireless technology that enables communication between digital
devices, such as smartphones and computers. The maximum communication distance may vary depending on the
presence of obstacles (people, metal objects, walls, etc.) or the electromagnetic environment.
Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off the
headset 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.

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 audio playback on the headset 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.
The headset 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.
Bluetooth connections with all Bluetooth devices cannot be guaranteed.
Bluetooth devices connected with the headset 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 headset 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.

Note on static electricity

If you use the headset when the air is dry, you may experience discomfort due to static electricity accumulated on
your body. This is not a malfunction of the headset. You can reduce the effect by wearing clothes made of natural
materials that do not easily generate static electricity.

Notes on wearing the headset

Because the headset achieves a tight seal over the ears, forcibly pressing it against your ears or quickly pulling it off
can result in eardrum damage. When putting on the headset, the speaker diaphragm may produce a click sound. This
is not a malfunction.

Other notes
Do not subject the headset to excessive shock as it is a precision device.
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 headset when folding.
When you use the headset as wired headphones, use the supplied headphone cable only. Make sure that the
headphone cable is firmly inserted.
115
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 headset for long periods, including when it is stored, as it may cause
deformation.
If you experience discomfort while using the headset, stop using it immediately.
The earpads may be damaged or deteriorate with long-term use and storage.
The headset is not waterproof. If water or foreign matter enters the headset, it may result in fire or electric shock. If
water or foreign matter enters the headset, stop use immediately and consult your nearest Sony dealer.
Cleaning the headset

When the headset exterior is dirty, wipe it clean with a soft dry cloth. If the headset is particularly dirty, soak a cloth in
diluted neutral detergent, and wring it well before using it to clean the headset. Do not use solvents such as thinner,
benzene, or alcohol, as they may damage the finish on the surface of the headset or cause other damages.

Do not use the headset near medical devices

Radio waves can affect cardiac pacemakers and medical devices. Do not use the headset in crowded places such as
crowded trains or inside a medical institution.
The headset has magnet(s) which may interfere with pacemakers, programmable shunt valves for hydrocephalus
treatment, or other medical devices. Do not place the headset close to persons who use such medical devices.
Consult your doctor before using the headset if you use any such medical devices.

Keep the headset away from magnetic cards

The headset has magnets. If a magnetic card comes near the headset, the card magnet may be affected or become
deactivated.

Low sound quality, or noise or unusual sound can be heard.

Turn down the volume of the playback device if it is too loud.

When playing music, check the connection status of the headset and the transmitting Bluetooth device. When the
headset and the transmitting Bluetooth device are connected via an HFP or HSP Bluetooth connection, switch the
Bluetooth connection to A2DP with the connected device.
Some devices that emit ultrasonic sound waves designed to repel rodents may occasionally be installed at the
entrances of commercial facilities or subway stations. Near such devices, the ultrasonic sound waves may cause
noise or unusual sound to be heard from the headset. Leave the place where the noise or unusual sound is heard. Or
turn off the noise canceling function/Ambient Sound Mode from the “Sony | Headphones Connect” app.
When using a video calling application on a computer, switch the Bluetooth connection to HFP or HSP by operating
the computer.
During a video call, sound quality may become low due to the conditions of the communication line.
If the headset connects to the previously connected Bluetooth device, the headset may only establish the HFP/HSP
Bluetooth connection when it is turned on. Use the connected device to connect via an A2DP Bluetooth connection.
When listening to music from a computer on the headset, the sound quality may be poor (difficult to hear the singer’s
voice, etc.) for the first few seconds. This is due to the computer specifications (priority on stable connection at the
start of transmission and then switches to priority on sound quality several seconds later) and is not a headset
malfunction.
If the sound quality does not improve after a few seconds, use the computer to establish an A2DP connection. As for
the operations on your computer, refer to the operating instructions supplied with the computer.
When [Connect to 2 devices simultaneously] is turned on with the “Sony | Headphones Connect” app, LDAC cannot
be used. If you want to use LDAC for music playback, turn [Connect to 2 devices simultaneously] off.

The noise canceling effects are not sufficient.

Make sure the noise canceling function is turned on.

Put on the headset snugly to a comfortable position.
The noise canceling function is effective in low frequency ranges such as airplanes, trains, offices, near air-
conditioning, and is not as effective for higher frequencies, such as human voices.
When the Adaptive Sound Control on the “Sony | Headphones Connect” app is turned on, the wearer’s actions, like
walking or running, are detected. The noise canceling function is automatically adjusted and the Ambient Sound
Mode may be activated according to these actions.
To make the most of the noise canceling function, turn off the Adaptive Sound Control, and try to turn on the noise
canceling function manually when you need it.
With the “Sony | Headphones Connect” app, check the setting of [Ambient Sound Control]. If it is set to [Ambient
Sound], the effect of noise canceling is reduced. Set it to the noise canceling mode.
