The sound from one side (left or right) of the headphones is very low.


    • The troubleshooting steps on this article have been written to work with all types of Sony® headphones. Because of this, some steps are only spelled out in general terms. The reason for this is that the process to perform that particular step is different depending on the headphones you have. For information specific to any particular model on how to complete any of the steps in this solution, refer to the operating instructions supplied with your product.
    • If you are using wireless headphones, a separate solution is available .

    Follow the steps below to troubleshoot this issue.
    NOTE: Each of the these steps represents a possible solution. Check the sound from the headphones after completing each step.

    1. Verify that the headphones are firmly plugged into the headphone jack on the unit.

      NOTE: If your player or audio device has more than one connection jack available, make sure the headphones are not connected to an audio-in or microphone jack.

    2. If the headphones have a volume control, set the volume on the source to a high level and use the volume on the headphones to adjust the volume to the desired listening level.
    3. Play from a different source, a different cassette tape, CD, or MiniDisc, or tune to a different station or channel.

      NOTE: If the issue is resolved at this point, the audio source is the cause.

    4. If audio is being heard from the left side of the headphones only, ensure that the device from which it is connected has stereo output capability.

      IMPORTANT: A mono device will only output sound to the left side.

      NOTE: Generally, if a device has an output jack labeled EARPHONE it will be mono, while an output jack labeled HEADPHONE will be stereo.

    5. If an extension cable is being used to connect the headphones, disconnect the extension cable and then connect the headphones directly.
    6. If connected to a portable player that uses a line remote, disconnect the remote and plug the headphones directly into the player.

      NOTE: If the issue is resolved, with the remote disconnected, the remote may require service.

    7. Test the headphones on another device.
    8. Test a different set of headphones on the device.


      • If the issue persists on another player, then the headphones should be replaced.

        Please contact a local or online authorized retailer to purchase a Sony product.

        For customers in Canada:

      • If the issue is still not resolved when using a new set of headphones, service for the player will be required. Go to Product Repair.
