Overview
Your iPhone has three microphones — bottom (primary), front (top bezel), and rear (near the camera) — each used for different functions. Identifying which microphone has failed is the first diagnostic step. A muffled or absent voice on calls usually points to the bottom microphone, while FaceTime audio problems may indicate the front microphone. Video recording issues often involve the rear microphone.
Common Causes
- Lint or debris completely blocking the bottom microphone opening next to the charging port
- Liquid damage corroding the microphone membrane or its soldered connection to the board
- Physical impact cracking the microphone capsule or dislodging its housing
- A screen protector or case partially covering the microphone opening and muffling input
- iOS software bug or app permission issue blocking microphone access
- Audio IC fault on the logic board affecting microphone signal processing
Signs & Symptoms
- Callers report not being able to hear you, or hearing you very faintly on phone calls
- Voice recordings in Voice Memos are silent or extremely quiet
- Siri cannot hear voice commands even in quiet environments
- Video recordings have no audio or a very muffled audio track
- Microphone works normally with earphones connected but not with the built-in mic
Should You Try DIY?
Attempting to repair iPhone microphone faults without proper tools and training can cause permanent damage. The microphone is soldered to flex cables running through the device; disturbing these without proper tools causes further failures. Always consult a professional technician.
Professional Solution
iTech Repairs technicians test all three iPhone microphones in isolation to identify which has failed and why. Debris blockage is cleared; a damaged microphone assembly is replaced; board-level audio IC faults receive component-level repair. All microphone repairs are tested across calls, voice memos, and video before the device is returned.

Frequently Asked Questions
- Why can't people hear me on my iPhone calls?
- If the other party cannot hear you, the bottom microphone is likely blocked by debris, damaged by liquid, or physically broken. The microphone used for calls is at the bottom of the phone next to the charging port.
- Can I test my iPhone microphone myself?
- Open Voice Memos and record a short clip. If your voice sounds muffled, quiet, or absent, the microphone has a problem. Testing in different apps also identifies whether it is microphone-specific or app-related.
