Low sound quality
Turn down the volume of the connected device if it is too loud.
Keep the headset away from a microwave oven, wireless LAN device, etc.
Bring the headset closer to the Bluetooth device. Remove any obstacles between the
headset and the Bluetooth device.
Keep the headset away from a TV.
When playing music, if 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.
When using a video calling application on a computer, switch the Bluetooth connection to
HFP or HSP with the computer.
During a video call, sound quality may become low due to the conditions of the
communication line.
If you connect a device with a built-in radio or tuner to the headset, broadcasts may not
be received or the sensitivity may be reduced. Move the headset away from the
connected device.
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
(e.g., 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.
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.

Set the headset to “Priority on stable connection” mode. For details, see “About the
sound quality mode”.
Remove any obstacles between the antenna of the connecting Bluetooth device and the
built-in antenna of the headset. The antenna of the headset is built into the part shown in
the dotted line below.
A: Location of the built-in antenna
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, put the Bluetooth device in the same direction as the antenna of the
headset to improve the Bluetooth communications.
When there is an obstacle, such as metal or a wall, between the headset and the
Bluetooth device
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
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.
Because Bluetooth devices and wireless LAN (IEEE802.11b/g/n) use the same
frequency band (2.4 GHz), microwave interference may occur and result in noise, audio
dropouts, or communications being disabled if this headset is used near a wireless LAN
device. In such a case, perform the following steps.
When connecting the headset to a Bluetooth device, use the headset at least 10 m
(30 feet) away from the wireless LAN device.

The available operating time is short (the duration of the
battery is short).
When the Equalizer or DSEE Extreme function is used, the available operating time of
the headset will be shorter.
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 a few recharges. If you will store the
headset for a long time, charge the battery once every 6 months to avoid over-discharge.
It is recommended to charge it 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 usage hours of the built-in rechargeable battery decrease significantly, the battery
should be replaced. Consult your nearest Sony dealer to replace the rechargeable
battery.

The effect of noise canceling is not sufficient.
Make sure that the noise canceling function is turned on.

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.
Check that the Adaptive Sound Control is turned off.
Check the setting of the Adaptive Sound Control on the “Sony | Headphones Connect”
app. When the Adaptive Sound Control is turned on, the noise canceling function may
become insufficient.
With the “Sony | Headphones Connect” app, check the setting of [Ambient Sound
Control]. If it is set to [Wind Noise Reduction] or [Ambient Sound], the effect of noise
canceling is reduced. Set it to the noise canceling mode.

The headset reacts incorrectly.
When connected with the computer, depending on the computer application you are
using, music playback may not stop even if you remove the headset, but this is not a

If the operation of the headset changes unintentionally, for example, ambient sound is
heard suddenly, check the setting of [Ambient Sound Control] with the “Sony |
Headphones Connect” app. If it is set to [Wind Noise Reduction] or [Ambient Sound], the
effect of noise canceling is reduced. Set it to the noise canceling mode.
