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
When the headset is connected to an iPhone or iPod touch over an HFP (Hands-free Profile) Bluetooth connection, it will
show an icon that indicates the remaining battery charge of the headset on the screen of the iPhone or iPod touch.
The display position is an example.
A: Remaining battery charge of the headset
B: 100% - 71%
C: 70% - 51%
D: 50% - 21%
E: 20% or lower (requires charging)
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.
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 as “100%”, “70%”, “50%” or “20%” in the
connected Bluetooth device column. 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.
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 less than 1%. The headset cannot be charged with the charging case in this case.
28
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 | 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.
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.

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 microphone part on the left or right headset unit with your hand, etc. The effect of the noise canceling function or
Ambient Sound Mode may not work properly or a beeping sound (feedback) may occur. If any of this is the case, remove your
hand, etc. from the left or right microphone part.

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.

Hint
When receiving a call on a smartphone or mobile phone, some smartphones or mobile phones may receive a call on the phone
instead of the headset. When using HFP connection, transfer the call to the headset by using your smartphone or mobile phone.
The headset volume during a call and during music playback can be independently adjusted. Changing the call volume does not
change the volume of music playback and vice versa.
You can also enjoy hands-free calls even when you are using only one headset unit. When you receive an incoming call, answer
the call with the headset unit you are using. 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, playback may not pause even when you receive an
incoming call while playing back music. When you receive an incoming call while playing back music, playback may not resume
automatically even if you finish the call.
Use a smartphone or mobile phone at least 50 cm (19.69 in.) 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.
Even when the volume adjustment function has been assigned to the button with the “Sony | Headphones Connect” app, you
cannot adjust the volume on the headset during a call. Adjust the volume on the connected device. If you are unable to adjust the
volume on the connected device, adjust the volume in the “Sony | Headphones Connect” app.

Making a call
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.
Connect the headset to a smartphone or mobile phone via a Bluetooth connection.
1
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 on the left and right headset units.
A: Microphones (left, right)

Hint
The headset volume during a call and during music playback can be independently adjusted. Changing the call volume does not
change the volume of music playback and vice versa.
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 (19.69 in.) 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.
Even when the volume adjustment function has been assigned to the button with the “Sony | Headphones Connect” app, you
cannot adjust the volume on the headset during a call. Adjust the volume on the connected device. If you are unable to adjust the
volume on the connected device, adjust the volume in the “Sony | Headphones Connect” app.
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 operates within a range of about 10 m (32.8 ft). 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.
The headset does not support multipoint connection.
With multipoint function support, the headset can connect to a music playback device (A2DP profile compatible
device such as portable music player, etc.) and a communication device (HFP or HSP profile compatible device such
as smartphone, etc.) at the same time, and you can listen to music while waiting for an incoming call or during a call.
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
108
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 using the headset, stop using it immediately and consult a doctor
or your nearest Sony dealer.
For long-term use, it is recommended that you remove the headset from your ears on a regular basis.
Other notes
Do not subject the headset to excessive shock as it is a precision device.
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.
When using the headset in the rain or snow, or in humid locations
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.

Low sound level
If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your
ears, you may not obtain the correct sound qualities or volume.
If any of this is the case, try the following.
Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud
tip sizes in order from the larger ones to the smaller ones. The most suitable size of the earbud tips for left and
right ears may be different.
Check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is
comfortably situated as deep in the ear canal as possible.
Adjust the volume on the connected device.
Even when the volume adjustment function has been assigned to the button with the “Sony | Headphones Connect”
app, you cannot adjust the volume on the headset during a call. Adjust the volume on the connected device. If you
are unable to adjust the volume on the connected device, adjust the volume in the “Sony | Headphones Connect”
app.
Connect the Bluetooth device to the headset once again.
The sound conduits (sound output tubes), air holes, and microphone part of the headset are not completely
watertight. If any water droplets are left in the sound conduits, air holes, or microphone parts, the sound level
becomes low temporarily. However, this is not a malfunction. See “When you have finished using the headset” and
dry the headset as described before use.
Set the headset units into the charging case, and close the charging case lid.
You may be able to resolve some issues by setting the headset units into the charging case.
Reset the headset.
Initialize the headset, and pair the headset and the device again.
Note
Depending on the connected device, the volume of the device and the headset may or may not be synced. If the volume on a
device is not synced to the volume on the headset, it will not be possible to use the device to turn up the volume on the headset
once the volume is turned down on the headset.
In that case, turn up the volume of both the headset and the connected device.
If the sound is still low even after adjusting the volume on the connected device, adjust the volume with the “Sony | Headphones

Low sound quality, or noise or unusual sound can be heard.
If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your
ears, you may not obtain the correct sound qualities, noise canceling effects, or call performance.
If any of this is the case, try the following.
Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud
tip sizes in order from the larger ones to the smaller ones. The most suitable size of the earbud tips for left and
right ears may be different.
Check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is
comfortably situated as deep in the ear canal as possible.
If you press the button on the left or right unit when the headset is not connected via a Bluetooth connection, you will
hear a notification sound indicating that the headset is turned on.
Turn down the volume of the playback device if it is too loud.
Switch the Bluetooth connection to A2DP with the connected device when the headset and the transmitting Bluetooth
device are connected via an HFP or HSP Bluetooth connection.
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 after a connection is established. 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.
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.

Bluetooth communications may be disabled, or noise or audio dropout may occur under the following conditions.
When there is a human body between the headset and the Bluetooth device
In this case, moving the Bluetooth device closer to the antenna of the headset may improve the Bluetooth
communications.

In places with wireless LAN, where a microwave oven is used, electromagnetic waves are generated, etc.
Where there are other wireless communication audio devices or other people nearby, such as in train station
premises or on a crowded train
If you are enjoying music with your smartphone, the situation may be improved by closing unnecessary apps or
restarting your smartphone. If you are enjoying music with your computer, close unnecessary applications or
windows and restart the computer.
Connect the headset and the Bluetooth device once again.
Set the headset units into the charging case and close the charging case lid, and then remove the headset from the
charging case to connect the headset to the Bluetooth device.

in your hand, a beeping sound (feedback) may be heard. This is not a malfunction. If any of this is the case, remove
your hand, etc. from the left or right microphone part.
