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 responding. Even when they do hear you, it’s very faint and they can barely hear you.

Why Can’t Anyone hear me on my iPhone?

No one can hear you on your iPhone calls because there’s a problem with your iPhone microphones. Your microphones are most likely filled with lint and dirt particles that have been clogged up in the grills. If these microphones are blocked, people aren’t going to hear you.

Therefore, you’ll need to clean them in order for people to hear you.

Blow Compressed Air in the Microphones

Different iPhone mics

There are 3 mics on 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.

Speak into a Different Microphone

Speak into bottom mic to be heared

Since there are 3 different mics, you should use 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 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

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 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.
