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

These are general troubleshooting steps for sound issues with headphones. Refer to the product manuals for model-specific information. Check if the sound issue is resolved after performing each step.

1. Make sure your headphones are firmly plugged into the headphone jack of the source device.
   • If your player or audio device has more than one connection jack, make sure the headphones aren't connected to an audio-in or microphone jack.
2. Set the source device volume to a high level, and if your headphones have a separate volume control, adjust it to the desired listening level.
3. Play back audio from a different app, playback media, channel, or station.
   • If the issue is resolved at this point, the audio source is the cause.
4. If you only hear audio from the left side of your headphones, make sure the audio source has stereo output capability.
   • IMPORTANT: A mono device will only output sound to the left side.
   • 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 you use an extension cable to connect your headphones, disconnect it and connect your headphones directly.
6. If you're using a portable player that uses a line remote, disconnect the remote and plug your headphones directly into the player.
   • If the issue is resolved with the remote disconnected, the line remote may require repair.
7. Test your headphones on another device.
8. Test a different set of headphones on the device.
   • If the issue persists on another player, then your headphones should be replaced.
