No sound, no sound from one side, low sound level

Common

  • Check that both the headset and the connected device are turned on.
  • Adjust the volume of the headset and the connected device. Turn up the volume if it is too low.
  • When the computer’s volume setting is muted or low, change the computer’s volume setting.
  • When the chat volume is low, ask the chat partner to change the microphone volume.
  • The volume balance between a game and chat may be leaning toward either the game volume or the chat volume being louder. You can adjust the volume balance between the game and chat using “INZONE Hub” or the PS5™. You can also adjust the volume balance between the game and chat using the headset by changing the function assigned to the touch sensor to [Game/Chat Balance Control] on “INZONE Hub” or the “Sony | Headphones Connect” app.
  • Make sure that the output setting of the computer is set to [INZONE Buds - Game] or [INZONE Buds - Chat].
  • Make sure the in-game output setting is set to [INZONE Buds - Game] or [INZONE Buds - Chat].
  • Restart your computer, PS5, or USB Type-C compatible smartphone.
  • 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. All of the pairing information will be deleted. Pair the headset and the Bluetooth device again.

When connected with the USB transceiver

  • Check that the USB transceiver is inserted as firmly as needed.
    If the smartphone is in a phone case, the USB transceiver may not be inserted as firmly as needed. If the issue persists, remove the phone case and check the USB transceiver again.
  • Switch the slide switch of the USB transceiver to “PC” or “PS5/MOBILE” according to the connected device.
  • If the headset is in the Bluetooth mode, hold your fingers to the touch sensors on both the left and right headset units and switch to USB transceiver mode.
  • Connect the USB transceiver directly to the computer, PS5, or USB Type-C compatible smartphone, and not via a USB hub.
  • Make sure that the headset is connected to the USB transceiver connected to the computer, PS5, or USB Type-C compatible smartphone.
    • Whether the connection indicator (white) on the USB transceiver is lit
    • Whether the headset is displayed on “INZONE Hub” and various settings can be made when connected to a computer
  • When connected to a Bluetooth device that does not support LE Audio via the USB transceiver, sound may not be produced on one side or the headset may remain in Bluetooth mode. Initialize the headset, and then connect the USB transceiver again.
  • If the headset cannot be connected to the USB transceiver connected to a computer, PS5, or USB Type-C compatible smartphone, follow the procedure below to perform pairing again with the USB transceiver.
    1. Connect the USB transceiver to a computer or game console such as a PS5.
    2. Set both headset units correctly into the charging case and leave the charging case lid open.
    3. With the charging case lid open, press and hold the pairing button of the charging case for about 5 seconds or more.
      The headset goes into pairing mode and the indicator (blue) on the charging case repeatedly flashes twice in a row.
    4. Press and hold the connect button on the USB transceiver for about 5 seconds or more.
      Press the connect button with an object with a thin tip that will not break, like a paperclip.
      The USB transceiver goes into pairing mode, and the connection indicator (white) on the USB transceiver repeatedly flashes twice in a row.
    5. Remove both headset units from the charging case and then put the headset units into your ears.
      When pairing is complete, a notification sound is emitted from the headset and the connection indicator (white) on the USB transceiver lights up.

    Note

    • If the last connected Bluetooth device is placed near the headset, the headset may automatically connect to the device when you turn on the headset and may not connect to another device.
      If this occurs, cancel the connection on the last connected Bluetooth device or turn off the Bluetooth function on that device.
  • You cannot use a wireless 2.4 GHz connection with a computer or PS5 and Bluetooth connection at the same time.
  • Depending on your USB Type-C compatible smartphone, you may need to configure some settings to connect with the USB transceiver. The name of the settings displayed on the connected smartphone may vary depending on the connected smartphone and can include names, such as “Detect USB device” or “Enable USB On-The-Go connection”. For details, refer to the operating instructions for the USB Type-C compatible smartphone.

When connected via a Bluetooth connection

  • If the connected Bluetooth device does not support LE Audio, the headset does not produce sound.
    If the headset is connected to this type of device via a Bluetooth connection, initialize the headset. After initializing the headset, connect the supplied USB transceiver.
  • If the headset is in the USB transceiver mode, hold your fingers to the touch sensors on both the left and right headset units and switch to the Bluetooth mode.
  • When playing music, check that the headset and the transmitting Bluetooth device are connected via a Bluetooth connection.
  • Check that the connected device is playing back.
  • Connect the Bluetooth device to the headset once again.
  • Pair the headset and the Bluetooth device again.
  • Restart the Bluetooth device such as the smartphone you are using.
  • Restart the music app or video app.

Note

  • Connection is not guaranteed with the USB ports of TVs, etc.
  • If the volume is turned down on the computer or USB Type-C compatible smartphone while connected via the USB transceiver, the volume cannot be turned up very high using the headset. To turn the volume up higher, adjust the volume on the computer or USB Type-C compatible smartphone.
  • If the volume is turned down on the connected device while connected via Bluetooth connection, the volume cannot be turned up very high using the headset. To turn the volume up higher, adjust the volume on the connected device.

When there is no sound on only one side

  • Depending on the smartphone app or computer application (which requires a CCP profile), you may hear sound from only one headset unit.
  • Check if the Bluetooth connection has been terminated. If terminated, make the Bluetooth connection again.
  • Check if the Bluetooth device supports LE Audio. If LE Audio is not supported, initialize the headset and then connect the supplied USB transceiver.
