The required time for fully charging the left and right headset units is about 1.5 hours.

System requirements for battery charge using USB

USB AC adaptor
A commercially available USB AC adaptor capable of supplying an output current of 0.5 A (500 mA) or more

USB cable
Commercially available USB Type-C cable (compliant with USB standards)

Personal computer
Personal computer with a standard USB port

We do not guarantee operation on all computers.

Operations using a custom-built or homebuilt computer are not guaranteed.

Hint
The headset can be also charged by connecting the charging case to a running computer using a commercially available USB
Type-C cable.

Note
Charging may not be successful depending on the type of USB AC adaptor.

The headset cannot be charged when the computer goes into standby (sleep) or hibernation mode. In this case, change the
computer settings, and start charging once again.

If the indicator (orange) on the charging case lights up for about 3 seconds and then turns off when the left and right headset units
are removed from the charging case, the remaining battery charge of the charging case is low. Charge the charging case.

If the indicator on the charging case does not turn on even when the left and right headset units are removed from the charging
case, the battery charge of the charging case is empty. Charge the charging case.

If the headset is not used for a long time, the rechargeable battery usage hours may be reduced. However, the battery life will
improve after charging and discharging several times. If you store the headset for a long time, charge the battery once every 6
months to avoid over-discharge.

If the headset is not used for a long time, it may take longer to charge the battery.

While charging, be sure to keep the charging case lid closed to prevent the battery of the charging case from being wasted.

If there is a problem with the rechargeable battery of the headset or the charging case and something unusual is detected during
charging, the indicator (orange) on the charging case flashes.
It is recommended to charge in a place with an ambient temperature between 15 °C and 35 °C (59 °F - 95 °F). Efficient charging
may not be possible beyond this range.
If the problem persists, consult your nearest Sony dealer.

If the headset is not used for a long time, the indicator (orange) on the charging case may not immediately light up when
charging. Wait a moment until the indicator (orange) lights up.

22
 If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult your nearest
Sony dealer.

Avoid exposure to extreme temperature changes, direct sunlight, moisture, sand, dust, and electrical shock. Never leave the
headset in a parked vehicle.

When connecting the headset to a computer, make sure to connect it directly to the computer with a USB Type-C cable. Charging
will not be properly completed when the headset is connected through a USB hub.

The headset and the charging case may become warm during charging or for a while after charging. However, this is not a
malfunction.

If you shake the charging case forcefully, you will hear a rattling sound; however, this is the sound of the headset units moving
inside the charging case and not a malfunction.

Checking the remaining battery charge

You can check the remaining battery charge of the rechargeable batteries of the headset and the charging case by the
following operations.

If the remaining battery charge of the headset becomes low when the headset is removed from the
charging case or while using the headset
If a warning beep sounds and the voice guidance says, “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 (iOS 13 or later)

When the headset is connected to an iPhone or iPod touch via an HFP (Hands-free Profile) Bluetooth connection, you
can check the remaining battery charge of the headset on an iPhone or iPod touch. For more details, refer to the
operating instructions supplied with the iPhone or iPod touch.
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, you can check the
remaining battery charge of the headset on the smartphone. For more details, refer to the operating instructions supplied
with 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.

Checking the remaining battery charge of the charging case

If the indicator (orange) on the charging case lights up when both headset units are removed from the charging case,
or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the
charging case is about 20% to 1%. The charging case cannot sufficiently charge the headset with this remaining level
of battery charge.
If the indicator on the charging case does not light up when both headset units are removed from the charging case,
or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the
charging case is at less than 1%. The headset cannot be charged with the charging case in this case.

Hint
The remaining battery charge of the headset may be different on the left and right sides depending on how you use them.
When checking the remaining battery charge on an iPhone/iPod touch or Android smartphone while using both headset units, the
remaining battery charge of the headset unit with less remaining battery charge between the left and right headset units is
displayed. When using only one headset unit, the remaining battery charge of the headset unit you are using is displayed.

You can also check the remaining battery charge of the headset unit and the charging case with the “Sony | Sound 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.

26
 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.

How to make a wireless connection to Bluetooth devices

You can enjoy music and hands-free calling with the headset wirelessly by using your Bluetooth device’s Bluetooth
function.

Pairing

To use the Bluetooth function, both of the connecting devices must be registered in advance. The operation to register a
device is called “pairing”.
Pair the headset with the device manually.

Connecting to a paired device

Once a device is paired, it is not necessary to pair it again. Connect to devices already paired with the headset using the
methods necessary for each device.

Supported codecs

A codec is an “audio coding algorithm” used when transmitting sound wirelessly via a Bluetooth connection.
The headset supports the following 2 codecs for music playback via an A2DP connection: SBC and AAC.

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.

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.

You can enjoy a hands-free call with a smartphone or mobile phone that supports the Bluetooth profile HFP (Hands-free
Profile) or HSP (Headset Profile), via a Bluetooth connection.

If your smartphone or mobile phone supports both HFP and HSP, set it to HFP.
The operation may vary depending on the smartphone or mobile phone. Refer to the operating instructions supplied
with the smartphone or mobile phone.
Depending on the connected device or the application you are using, the functions may not work properly even if you
try to operate them with the headset.

1 Connect the headset to a smartphone or mobile phone via a Bluetooth connection.

2 Operate your smartphone or mobile phone to make a call.

When you make a call, the dial tone is heard from the headset.
If you make a call while listening to music, playback pauses automatically.
If playback is not paused, operate the headset to pause playback.
You can talk using the microphones (A) on the left and right headset units.

If no dial tone is heard via the headset

Use your smartphone or mobile phone to transfer the call to the headset.

3 Operate the smartphone or mobile phone to adjust the volume.

4 When you have finished your call, press the button twice quickly on the left or right headset unit to end the
call.

If you made a call during music playback, music playback resumes automatically after ending the call.

88
 Hint
The volume can also be adjusted on the “Sony | Sound Connect” app.
The headset volume during a call and during music playback can be independently adjusted. Even if you change the volume
during a call, the volume of music playback does not change.

You can also enjoy hands-free calls even when you are using only one headset unit. If you remove the other headset unit from the
charging case while you are talking with only one headset unit, you can talk with both headset units.

Note
Depending on the connected device or playback application you are using, when you make a call during music playback,
playback may not resume automatically even after you finish the call.

Use a smartphone or mobile phone at least 50 cm (1.6 ft) away from the headset. Noise may result if the smartphone or mobile
phone is too close to the headset.

Your voice will be heard from the headset through the headset’s microphone (Sidetone function). In this case, ambient sounds or
the sounds of the headset operation may be heard through the headset, but this is not a malfunction.

When you are using only one headset unit, be sure to set the other headset unit into the charging case.

Depending on the caller’s voice characteristics or the ambient environmental noises, the audio signal processing that is mounted
on the headset may not work well and the call sound quality may be 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 temperature rise

While charging the headset units or charging case, or when using the headset for a long time, the temperature of the
headset units or charging case may rise, but this is not a malfunction.

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

After use, remove the headset from your ears slowly.
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 wearing the headset, the speaker diaphragm may produce a click sound. This
is not a malfunction.
The long-term use of the headset may cause symptoms such as itching and irritation in the ears.
If you experience any of the above symptoms while the headset is in use, stop using it immediately and consult a
doctor or your nearest Sony dealer.
104
 For long-term use, it is recommended that you remove the headset from your ears on a regular basis.

The Bluetooth function may not work with a mobile phone, depending on the signal conditions and the surrounding
environment.
If you experience discomfort while using the headset, stop using it immediately.
The earbud tips may be damaged or deteriorate with long-term use and storage.
If the earbud tips become dirty, remove them from the headset and gently wash them by hand using a neutral
detergent. After cleaning, thoroughly wipe off any moisture.
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. In particular, be careful in the following cases.

When using the headset near a sink or liquid container

Be careful that the headset does not fall into a sink or container filled with water.
