Archived - Troubleshooting iPod's headphones
If you think your iPod or iPod mini headphones aren't working correctly, try these simple troubleshooting steps.
If you have the Apple In-Ear Headphones, first see Tip - Getting Optimal Audio Quality before continuing.
Connect the iPod headphones to the sound output port ("speaker jack") on your computer or another audio device that has a 3.5 mm stereo headphone jack. If the issue with the headphones is still apparent, you can request replacement headphones from the iPod Service Website.
If the issue with your iPod headphones is not apparent on another device, try connecting a different set of headphones with a 3.5 mm plug to your iPod. If the issue is apparent with these headphones on your iPod, you can arrange to have your iPod repaired at the iPod Service Website.
