Q: iPhone 6s sound quality issue on calls.

Hi Sfgo72,

If the sound quality for the calls you are receiving on your new iPhone 6s is not good, try the troubleshooting steps below:

If you can‘t hear a person on a call or voicemail or if the sound isn‘t clear on your iPhone

When you're on a call or listening to voicemail on your iPhone, you might not be able to hear a person's voice clearly. Or you might hear crackling, static, or generally poor sound quality. Learn what to do. 

iPhone Volume and Receiver

Turn up the volume

While you're on a call, adjust the volume with the volume buttons. Make sure that you can see the volume indicator on the screen when you press the volume buttons.

Check the connections

If your iPhone is connected to a headset, you won't be able to hear through the iPhone receiver or using speakerphone. Follow these steps, testing after each.

1. Make sure that you don't have anything plugged in to the headphone jack or the dock connector.
2. Go to Settings > Bluetooth and turn off Bluetooth.

Clear the receiver

The iPhone receiver won't work properly if it's blocked or dirty.

Follow these steps, testing after each:

• Make sure nothing is blocking the receiver, such as a case or film.
  If you have a new iPhone, remove the plastic film on the front and back of the device.
• Check the receiver opening to see if it's blocked or dirty. If necessary, clean the receiver opening with a clean, small, dry, soft-bristled brush.
• While you're on a call, turn on speakerphone. If you still can't hear, then your network or reception could be the issue. Try calling again later or from a different location.

Check the receiver

Follow these steps to see if the issue is with your receiver or your network:

1. Open the Voice Memos app and record a short audio clip.
2. Tap  in the upper-right corner of your screen to switch playback between the speaker and receiver.
3. Tap  to play the voice memo through the receiver on your device.
4. If you hear the voice memo and it sounds normal (without distortion, crackling, or static), there might be an issue with your carrier network or voicemail system. If you still hear no sound or poor quality sound, contact Apple Support.

Restart and update

1. Restart your iPhone and test again.
2. If there's still no sound or poor sound quality, update to the latest version of iOS.
