No audio in one ear

If sound is missing from the left or right ear while listening to your product, try the following:

Remove the device from its case or protective sleeve (if applicable).

If a case or protective sleeve is on your device, try removing it to determine if it is preventing the headphones plug from making a full connection.

Be sure the headphone openings are clean and free of debris.

Check for blockages in the headphone mesh grille and headphone opening. Excessive debris can result in low audio, poor sound quality or missing audio channels.

If connected, bypass any adapters or extension cables.

If your product connects to the device using an extension cable or adapter, disconnect the extension cable or adapter to determine if the issue is related to it.

Try a different app.

If the issue only occurs with a particular app, it is likely related to the app or app settings.

Plug in a different pair of headphones.

Connect another pair of headphones to the audio device to determine if the issue is with the device or its settings.
