IPhone 6s speaker / calls

Hello Momb8686,

You mention the other caller can't hear you and the headphone sounds still play on the phone rather than through the headphones. Are you using the headset when the other person can't hear you?

Please check out the troubleshooting in this article for headset issues.

If your headset isn't working - Apple Support

You can fix most headset issues with a few steps. Try these first:

1. Make sure that the headset has a built-in microphone.
2. Unplug the headset and clear any debris from the headset jack. Then plug it back in.
3. Make sure the headset is plugged in all the way. If you’re using a case, remove it to make sure it’s not getting in the way.
4. Check the headset cable, connector, remote, and earbuds for damage. Make sure they’re not blocked or dirty.
5. Try using another headset. If the issue happens with the other headset, contact Apple Support for help. If the other headset works, contact the headset manufacturer.
6. Try using a different iOS device with your headset. If the issue happens with the other iOS device, contact the headset manufacturer. For Apple headsets, contact Apple support.

If your headset still isn't working, follow the steps below for the issue.

If you can't hear through your headset

1. Adjust the volume on your iOS device. Try using the volume buttons and the Volume slider in Control Center.
2. Unplug the headset to check if you can hear from the speaker on your iOS device. Can't hear from the speaker?
3. If you can hear from the speaker and you still can't hear from your headset, contact the headset manufacturer. For Apple headsets, contact Apple Support.

If people can't hear you on a call or you can't record sound

1. Make sure that nothing is covering the headset microphone.
2. Unplug the headset and try recording something with Voice Memos and the microphone built into your iOS device. If Voice Memos doesn't record sound, you might have an issue with your microphone.

If that's not it, please give us the details.
