iPhone Microphone Not Working?

People can't hear you on calls? Voice memos not recording? Siri can't understand you? Your iPhone has multiple microphones - let's figure out which one isn't working and how to fix it.

⏱️ 5-15 min 💪 Easy 🎤 All iPhones

Your iPhone's Microphones

iPhones have 3-4 microphones in different locations:

  • Bottom mic: Next to Lightning/USB-C port - used for calls
  • Front mic: In earpiece speaker area - used for FaceTime, speakerphone
  • Rear mic: Near camera - used for video recording
  • Top mic: (some models) For noise cancellation

Quick Test

Test each microphone:

  1. Voice Memos: Record a memo and play it back → tests bottom mic
  2. Camera: Record a video and play it back → tests rear mic
  3. FaceTime call: Can they hear you? → tests front mic
  4. Siri: Ask a question → tests active mic

Fixes to Try

1 Clean the Microphone Openings

Dust and debris block microphone holes:

  1. Locate all microphone openings (bottom, front, rear)
  2. Use a soft-bristled toothbrush (dry)
  3. Gently brush across the mic openings
  4. Use compressed air in short bursts (not too close)
  5. Check for visible debris with a flashlight
⚠️ Don't: Use metal objects (damages mic), blow with mouth (moisture), or use liquids.

2 Remove Case and Screen Protector

Cases can block microphone holes:

  • Remove your case completely
  • Check if screen protector covers any mics
  • Test microphone without accessories
  • If it works, get a case with proper cutouts

3 Force Restart iPhone

Clears software glitches affecting microphone:

Volume Up → Volume Down → Hold Side Button until Apple logo

4 Check App Permissions

Apps need permission to use the microphone:

  1. Go to Settings → Privacy & Security → Microphone
  2. Make sure apps that need mic access have it enabled
  3. Toggle off and on for problem apps

5 Disable Noise Cancellation

Phone noise cancellation can sometimes cause issues:

  1. Go to Settings → Accessibility → Audio/Visual
  2. Toggle Phone Noise Cancellation off
  3. Test your microphone

6 Disconnect Bluetooth Devices

iPhone might be using a Bluetooth device's mic:

  1. Go to Settings → Bluetooth
  2. Disconnect all audio devices (AirPods, headsets, car)
  3. Test your iPhone's built-in mic

7 Update iOS

Microphone bugs are occasionally fixed in updates:

  1. Go to Settings → General → Software Update
  2. Install any available updates

8 Reset All Settings

If software issues persist:

  1. Go to Settings → General → Transfer or Reset iPhone
  2. Tap Reset → Reset All Settings
  3. This won't delete your data but resets all settings

When Hardware Repair Is Needed

If cleaning and software fixes don't help, you likely have hardware damage:

  • Microphone stopped working after water exposure
  • One specific mic doesn't work (identified by testing)
  • Microphone worked before a drop/impact
  • Audio is consistently distorted or muffled

Microphone replacement is a moderate repair - the bottom mic is part of the charging port assembly on many models.
