If the headphones only play the sound through one side or differing sound levels is heard in each ear or the sound in general is not what you expected then it needs to be determined where the issue is with the headphones or with the audio source.
Each of these recommendations may resolve the issue. Check the sound of the headphones after following each recommendation.
- Make sure that all of the connections between the headphones and the audio device are tight and secure. A properly connected cable should not wiggle. If the plug wiggles that could indicate a loose connection.
NOTE: If there is wiggle or movement in any of the connection, it would be the result of the cable not being plugged all the way in, a faulty input or sometimes if the device you are connecting to has a case on it that is preventing a secure connection.
- Make sure that there is no debris (i.e.: no dust or lint) on the headphone jack. This may be inhibiting connectivity and causing sound issues.
- Make sure that all of the connections are clean. If oils from the hands gets builds up on the plug or sweat evaporates on the plug the salts and grime may prevent proper contact from occurring. The connecting jacks can be cleaned by wiping them with a dry, lint free towel.
- Try the headphones on a different audio device. If you connect to a different device and the issue is not present, you know the headphones are fine and the original audio source is the issue.
Some settings on an audio device that may cause sound issues.:
- Audio Limit Pre-set Setting: This will limit need to be changed to get the full audio signal out of the device and to the headphones.
- Mono Audio Setting: Using a mono audio device or setting the audio setting of the device to mono will cause the audio device to only play the sound through one side.
