So, you call up one of your friends on your iPhone and they answer. When you speak to them, they just keep saying “hello” “hello” “hello” because they can’t hear you respond. Even when they do hear you, it’s very faint and they can barely hear you.

Why Can’t People Hear Me On My iPhone?

If people can’t hear you on iPhone or FaceTime calls, it’s likely that your microphones are most likely filled with lint and dirt particles that have been clogged up in the grills. If these microphones are blocked, the sound can’t get through the mic so can’t hear you on calls. Therefore, you’ll need to clean them in order for people to hear you.

If your iPhone microphone is damaged, this can also affect how well someone can hear you on the other end. If the person on the other end can still hear you but it isn’t entirely clear, this can still be down to a problem with your iPhones microphone. Your ear speaker not working properly can be the product of too much wear over the months and years of you using your iPhone. Usually, there’s no way to fix this, however, you can take this to the Apple repair store and see what they can do for you.

Some people conduct calls on devices like AirPods or the Apple Earpods and sometimes there’s a problem with the microphone on these headphones. If people can’t hear you only when you’re using earphones, then it could be a problem with the earphone’s mic. Try to conduct calls using your iPhone’s mic and if people can hear you, then it looks like your earphones need replacing.

Another reason why your iPhone microphone isn’t working is because of a glitch. If it’s a rare situation that the caller can’t hear you, then it might be down to a software problem going on within your iPhone. If normally, people can hear you, then it’s safe to say that you can put it down to this. Software problems happen all the time on your iPhone so it’s nothing you should be worrying about.

How To Test If Your iPhone Microphone Is Not Working

If people can’t hear you on phone or FaceTime calls, you can test if your microphone is working by opening the Voice Memo app > tap the record button > speak to the bottom mic > stop the recording > playback the recording and see if you can hear yourself. If you couldn’t hear yourself, then callers won’t be able to hear you due to your microphone being broken. In this case, you need to contact Apple Support.

Fixing Person Can’t Hear You On iPhone or FaceTime Calls

Blow Compressed Air in the Microphones

Different iPhone mics

To find where the microphones are on your iPhone, you need to look for a small hole at the bottom of your iPhone, the grill at the top on the front screen, and the one behind the mic. There are 3 mics located around your iPhone and all 3 of them are probably filled with lint and dirt. The best way to get rid of this is to blow compressed air into all three microphones. This is going to push out the dirt stuck in there.

To remove the dirt in the microphone:

  1. Open some compressed air
  2. Blow it at the grill on the top
  3. Blow into the bottom left microphone
  4. Blow into the mic at back on the right of the camera
  5. Most of the dirt should be gone so people should hear you

If you notice after doing this that people are still struggling to hear you, or you want to make sure the problem is solved, go to the next step.

How to Turn On Your iPhone’s Microphone In Settings

If you’re using different apps to conduct calls and people are not hearing you at all, then it might be down to your mic not being enabled for this specific app. Before you can use an app for a call, it needs to have permission to use your iPhone’s microphone. If people outright can’t hear you during calls on other apps, not FaceTime or normal calls, then you’ll need to check the app’s permissions.

To turn on your iPhone’s microphone, go to Settings > Privacy > Microphone > make sure the app you’re using for calls if toggled on. If your mic wasn’t turned on, this was why people weren’t able to hear you. For example, if you used WhatsApp or Messenger, make sure they’re toggled on.

Another reason why your mic may not be working is that an app that has access to your mic has crashed or the microphone is still active within that app. This can stop the microphone from working properly. To fix this, you’ll need to turn off all of the microphone permissions for all the apps on your iPhone. Once you’ve done this, you need to close all of the apps. After you’ve followed all of the steps, you can turn on microphone access for the apps you were conducting calls with, and from there, test if people can’t hear you during the call.

Locate And Speak Into The Microphone Below Your iPhone

Speak into bottom mic to be heared

Since there are 3 different mics, locate the one on the bottom left microphone near the lightning port because it’s the biggest mic and it’s less likely to be filled with dirt. This is the microphone that is activated when you speak to people during calls.

This means that people are more likely to hear you when you use this speaker.

  • The bottom mic on the left of the lightning port is meant for calls.
  • The earpiece at the top is used for voice memos and facetime calls
  • The one on the back on the right of the camera records audio for videos

After knowing which mic you should use, people should be able to hear you without you putting it on speaker all the time.

Reset Network Settings to Remove Software Problems

The next thing that I’ll recommend you do is to reset your network settings. With your network settings are your call settings. If there’s an issue in these settings that are stopping people from hearing you, wiping this may fix this issue.

This is only going to change network settings so don’t worry about your data and content.

To wipe network settings:

  1. From the home screen, tap Settings
  2. Scroll down to, then tap General
  3. Scroll down to, then tap Reset
  4. Tap Reset Network Settings
  5. Tap Reset Network Settings to confirm

After doing this, call someone and check if they can hear you properly.

If people are still struggling to hear you, follow the next step.

Replace your Microphone If It’s Not Working

If you notice that people are still struggling to hear you, you’ll need to replace your microphone. This means that the whole bottom section of your iPhone will be replaced.

If you want to fix this with Apple, you can schedule an appointment with your nearest branch which will take a few weeks because of the demand.

You Might Notice That Siri Can’t Hear You

If you’re trying to talk to Siri and it can’t understand what you’re trying to say, then it’s safe to say that there’s a problem with your mic. If you notice that people can’t hear you during calls, and Siri is also unable to hear you, the best thing to do is to contact Apple Support to get the problem checked out.
