I have an iphone 4, when I plug in headphones I can pick up music and only background sounds, but no voices. It happens on every video or movie I see, but music works perfectly fine. Did anyone else have this problem or was it just me?

Hey there Srkupo,

It sounds like your vocal audio is not working with your headphones connected to your iPhone. I would start with the troubleshooting from the following article to help troubleshoot them named:

Resolve issues with iPhone, iPad, and iPod touch accessories

Update your software

Install the latest version of iOS. You can see which version is on your iPhone by going to the About screen.

If the device doesn't update successfully, the issue might be with your device and not the accessory. Learn how to check your iPhone, iPad, or iPod touch.

Disconnect and inspect the accessory, then restart your device

1. Disconnect the accessory and turn it off, if possible.
2. Inspect the connection between the accessory and device and make sure that no debris or other damage is present.
3. Restart your iOS device by turning it off, then back on. When the Home screen appears, reconnect the accessory.

Try a different device

Make sure the issue is with the accessory, if possible. Always use an identical or similar, compatible device with the accessory you're troubleshooting.

• If there's static coming from the left audio channel when you use headphones, try connecting the headphones to a similar device.
• If the device isn't syncing when connected to the dock, connect it directly to the computer using the Apple 30-pin to USB Cable or try another USB port.
• If you're using Lightning to 30-pin Adapter in a connection chain, try using the same adapter on a similar or identical device.

Restore iPhone, iPad, or iPod touch

Restore your iOS device. You should rarely need to use this step with an accessory issue. If the issue only affects a third-party accessory, contact the manufacturer before restoring the device.

If this does not resolve the issue could you elaborate on where you are listening to this content from to help isolate the issue?

Thank you for using Apple Support Communities.

All the very best,
