Wireless Noise Canceling Stereo Headset
WH-1000XM4
No sound
Check that both the headset and the connected device are turned on.
When playing music, check that the headset and the transmitting Bluetooth device are connected via an A2DP
Bluetooth connection.
When using a video calling application on a computer, check that the headset and the computer are connected via an
HFP or HSP Bluetooth connection. (A2DP is for music playback connections.)
Depending on the video calling application you are using, microphone settings may not be available. In that case,
disable Speak-to-Chat.
When you connect with 2 devices simultaneously with multipoint connection, depending on the connected device, the
device may keep sending the silent signal even if the playback of the music or video is stopped. In this case, the
headset remains connected with the device, and the connection may not be changed to another device. If the sound
from the second device cannot be heard after the playback is stopped on the first device, operate in the following
order and check whether the situation has improved.
Check with the "Sony | Headphones Connect" app that the setting of [Connect to 2 devices simultaneously] is on.
Stop the playback of the application on the first device.
Shut down the application on the first device.
Check that the headphone cable is connected firmly.
Turn up the volume if it is too low.
Check that the connected device is playing back.
If you are connecting a computer to the headset, make sure the audio output setting of the computer is set for a
Bluetooth device.
Pair the headset and the Bluetooth device again.
When Speak-to-Chat is enabled, the Speak-to-Chat mode may launch and respond to the audio (in particular,
recordings of conversations in foreign language study materials) that is playing even when the headset is not being
worn. In this case, use the headset buttons or touch panel to exit the Speak-to-Chat mode.
Reset the headset.
Charge the headset. Check if the sound is output from the headset after charging.
Initialize the headset, and pair the headset and the device again.
The situation may be improved by restarting playback devices such as your smartphone or computer.
