Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable battery in the following ways.
Check on your smartphone
When you are using an iPhone (iOS 13 or later)
When the headset is connected to an iPhone via an HFP (Hands-free Profile) BLUETOOTH connection, you can
check the remaining battery charge of the headset on an iPhone. For details, refer to the operating instructions
supplied with the iPhone.
The remaining charge which is displayed may differ from the actual remaining charge in some cases. This is 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 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. This is a rough
estimate.
Check with the power button
When you turn on the headset, the 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. This is a rough estimate.
The indicator also flashes in orange for about 15 seconds if the remaining battery charge is 10% or lower when the
headset is turned on.
Check with the voice guidance notification
When the rechargeable battery becomes low, the voice guidance will play in the following cases.
When the headset is turned on
When using the headset
When the battery becomes completely empty, an alarm sounds. The voice guidance plays, then the headset
automatically turns off.
Hint
You can also check the remaining battery charge of the headset with the “Sound Connect” app. Android smartphones and iPhone
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 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 in the following situations. In that case, repeatedly charge and
discharge the battery multiple times. The remaining battery charge will then be properly displayed.

Connecting the headset to 2 devices simultaneously (multipoint connection)
The headset can be simultaneously connected to 2 devices via BLUETOOTH connections, allowing you to perform 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 simultaneously via BLUETOOTH connections
The following occurs when attempting to connect a paired third device to a headset via a BLUETOOTH connection while
2 devices are already connected via BLUETOOTH connections.
The BLUETOOTH connection with the device that was last playing music will be maintained.
The BLUETOOTH connection with the other device will be disconnected.
Then a BLUETOOTH connection between the third device and the headset is established.
Pair the headset with 2 devices, respectively.

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 start playback by operating the second device while playing music on the first device, the music of the second
device will be heard 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 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 overlapping the
call on the first device. In this case, you can use the headset to answer or reject the second call, but you cannot end
the first call.
If you want to end the first call, you will need to operate the connected device.
If the second call is received without finishing the first call, the first call will continue silently. When the second call is
finished, the call will return to the first call.
Note
If the connected device switches at an unintended time, you may be able to prevent the device from switching by turning off the
notification and operation sound on your smartphone or lowering the volume.

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.
Depending on the BLUETOOTH device connected to the headset, the communication environment, and the
surrounding conditions, noise or sound cut out may occur.
The maximum communication distance of the headset is approximately 10 m (32.8 ft). The communication distance
may vary depending on the surrounding 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.
When you use the headset on an airplane, follow flight crew directions. Radio waves may affect instruments, causing
risk of accident due to malfunction.
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

Supported codecs
A codec is an “audio coding algorithm” used when transmitting sound wirelessly via a BLUETOOTH connection.
The headset supports the following codecs.
When connected using Classic Audio via an A2DP connection (for music playback): SBC, AAC
When the headset is connected using LE Audio, it supports LC3.
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.
LC3
This is an abbreviation for Low Complexity Communication Codec.
LC3 is a codec for LE Audio and achieves low latency transmission.
When music is transmitted using one of the following codecs from a device connected via Classic Audio, the headset
automatically switches to that codec and plays back the music in the same format.
SBC, AAC
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 connected device to set the codec.
When connected to LE Audio, the music playback is performed in LC3 codec. For LE Audio connections, use the “Sound
Connect” app and set [Bluetooth Connection Quality] to [Low latency]. The [Prioritize Sound Quality] setting at the time of
purchase does not support LE Audio connection.
Refer to the operating instructions supplied with the device you are connecting to, as some settings may be necessary in
advance.
