Why my headphones work only on mono is not working on stereo

This is the Mac Mini (desktop computer) forum.

If you mean that you only get mono out of your iPhone headphone jack than:

- Confirm that the headphones are not the problem by trying the headphones in another divice or trying other headphones in the iPhone

- If you confirmed the iPhone is the problem

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.

Try the following to rule out a software problem

- Check also Settings > General > Accessibility > Hearing. Make sure that the sound balance is not set all the way to "R" or "L".

- Reset the iPhone. Nothing will be lost

Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at

least ten seconds, until the Apple logo appears.

- Reset all settings

Go to Settings > General > Reset and tap Reset All Settings.

All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.

- Restore from backup

- Restore to factory settings/new iPod.

- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.

Apple Retail Store - Genius Bar

Aple will fix/exchange you iPod. See:
