How to fix iPhone 13 can hear others but they cannot hear me

If you can hear others on a call but they cannot hear you, the microphone on your iPhone 13 may be muted, blocked, or faulty. Use these steps to fix it.

Method 1: Check Mute and Volume

Ensure the iPhone is not on mute (silent switch).
During a call, check that the microphone icon is not crossed out; tap it to unmute.
Increase call volume with volume buttons.

Method 2: Clean the Microphone Ports

Dirt or debris can block the microphone.

Locate the microphone holes: bottom left of iPhone (primary) and earpiece area (secondary).
Gently clean with a soft brush or compressed air. Do not use liquids or sharp objects.

Method 3: Restart the iPhone

A soft reboot can clear temporary audio routing issues.

Hold Side and Volume buttons until power slider appears; slide to power off; wait 30 seconds; turn back on.

Method 4: Check Bluetooth and Audio Routing

If a Bluetooth headset is connected, the audio may be routed there, causing the iPhone’s mic to be disabled.

During a call, tap the speakerphone button.
Or go to Settings > Bluetooth and disconnect any paired devices to test.
Also check Control Center for AirPlay routing.

Method 5: Update iOS

Software bugs can affect microphone permissions and function.

Go to Settings > General > Software Update and install any available updates.

Method 6: Reset All Settings

If microphone settings are corrupted, a settings reset may help (does not delete photos/apps).

Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
Enter passcode; wait for restart.
Test calls again.

Method 7: Hardware Diagnosis

If the microphone still doesn’t work:

It may be physically damaged (water, drop).
The microphone component or audio IC could be faulty.

Visit an Apple Store or authorized repair service for diagnostics. For iPhone 13, weigh repair costs.

Most microphone issues are software-related; start with cleaning, toggles, and reset before seeking repair.
