Sound issues
Left earbud or speaker sounds lower than right. Anyone else having this problem?
If you can't hear any sound or if only one side of your headphones works
- Adjust the volume with the volume buttons on your iOS device or use the Volume slider in Control Center.
- To see if you need a replacement, try a second pair of headphones. If the second pair works, contact the manufacturer of the initial pair and ask if you need a replacement. If the second pair doesn't work, contact Apple Support.
If your headphones don't work with your iPhone, iPad, or iPod touch - Apple Support
