For the Apple iPad Pro and iPad Air (M4 Pro and M2 Air, 11 and 13 inch), different apps and call modes use different microphones. First, record a voice note before anything else. Remove the case, hold the phone away from your palm, and repeat the same recording. This is free and it explains a large share of these.
Differential
Likely causes of “Apple iPad Pro and iPad Air microphone is quiet, muffled or not working”, and how to tell them apart
- 1
A case or grip covering a microphone port
What separates it One situation fails and the others are fine — usually speakerphone or video, where a microphone away from the mouth is doing the work. A case with a misaligned cut-out, or a hand across the bottom edge, is enough.
How to confirm Remove the case, hold the phone away from your palm, and repeat the same recording. This is free and it explains a large share of these.
- 2
Lint in the microphone port
What separates it Audio has become progressively quieter or more muffled over months rather than failing suddenly. The ports are small and they live in a pocket.
How to confirm Look into the ports with a bright light. Record a voice note before and after clearing gently with a soft dry brush.
- 3
An app does not have microphone permission
What separates it It fails in one app and works in the voice recorder. Permissions are revoked by updates, by privacy settings and by users who tapped 'don't allow' months ago.
How to confirm Check that app's microphone permission specifically. This is the first thing to check when the failure is app-shaped.
- 4
A Bluetooth accessory is capturing the audio
What separates it Callers cannot hear you and the phone seems fine, with an accessory connected somewhere — often in another room or a car outside. The call's microphone is on the accessory.
How to confirm Disconnect Bluetooth entirely and repeat the call. This is a very common cause of 'nobody can hear me' with no fault anywhere.
- 5
Noise suppression removing the wrong thing
What separates it Voice sounds thin, cut off at the start of words, or drops in and out in a quiet room. Aggressive noise cancellation can misjudge a quiet speaker.
How to confirm Compare a recording in a normal room against one outdoors. Where the phone offers a voice isolation setting, changing it is the test.
- 6
A screen protector over the earpiece microphone
What separates it Calls held to the ear are affected while speakerphone is fine. A protector that covers the top slot muffles the microphone next to it.
How to confirm Check whether the protector's cut-out lines up with the slot.
- 7
The other end of the call
What separates it One person cannot hear you and everyone else can. Call audio has two ends and a network in between.
How to confirm Call someone else, and record a voice note locally. A clean local recording exonerates the phone completely.
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which situations fail and which work: handset call, speakerphone, video recording, voice note, and one specific app. Different microphones serve different situations.
- A voice note recorded locally, which tests the microphone without the network or the other party involved.
- Whether a case, grip or screen protector is fitted, and whether its cut-outs line up.
- Whether any Bluetooth accessory is connected, including ones out of the room.
- Whether the audio is quiet, muffled, cut off at the start of words, or absent — those describe different faults.
- Whether it changed suddenly or degraded over months.

0 of 8 completedRecord a voice note before anything else
ReversibleThis tests the microphone alone, with no network, no other party and no call software involved. A clean local recording exonerates the microphone entirely and moves the whole investigation to the call path or one app.
Map which situations fail
ReversibleHandset call, speakerphone, video, voice note and one app use different microphones in different combinations. One failing while others work is the single most useful fact here — it identifies which microphone, and it rules out the ones that work.
Disconnect every Bluetooth accessory and retry
ReversibleA connected accessory takes the call's microphone with it, including one in another room or a car parked outside. 'Nobody can hear me' with a perfectly working phone is this more often than any hardware fault.
Remove the case and keep your hand off the bottom edge
ReversibleA case with a misaligned cut-out, or a palm across the bottom microphone, is enough to muffle speakerphone and video while a handset call stays fine. Free to test, and it explains a large share of these.
Check the app's microphone permission
ReversiblePermissions are revoked by updates and by privacy settings, and a denial made months ago is invisible now. When the failure is confined to one app, this is the first thing to check and usually the last.
Inspect the ports under a bright light
ReversibleAudio that has become gradually quieter over months rather than failing suddenly is usually lint. Clear it with a soft dry brush — never a pin, never compressed air forced into the port, never liquid — and record the same voice note again to compare.
Test the same call to a different person
ReversibleCall audio has two ends and a network between them. One person unable to hear you while everyone else can is not your phone, and no amount of work on it will change that.
Compare a quiet room against a noisy one
ReversibleAggressive noise suppression can misjudge a quiet speaker and cut the start of words or drop the voice entirely. Where the phone offers a voice isolation setting, changing it and repeating the same recording is the test.
Model-specific
What is true of this model and not of its siblings
- Model scope
- M4 iPad Pro and M2 iPad Air, 11 and 13 inch. Apple iPad family; connector, cellular option, camera, biometric and iPadOS eligibility vary by exact model.
- Hardware — Apple tech-specs article
- 13-inch Tandem OLED display (2752x2064, ProMotion 10-120Hz), Apple M4 chip (8GB RAM on 256/512GB, 16GB RAM on 1TB/2TB), USB-C, supports Apple Pencil Pro and Apple Pencil (USB-C) only.
- Tier — Pro (M4, OLED)
- The flagship 13-inch iPad Pro with an M4 chip and a tandem-OLED 'Ultra Retina XDR' display — far brighter with true blacks. It uses a Thunderbolt/USB-4 USB-C port (fast external drives/displays) and supports the Apple Pencil Pro. Runs iPadOS.
- Apple Pencil Pro
- Supports the Apple Pencil Pro and USB-C Pencil — NOT the older 1st/2nd-gen Pencils. A Pencil that will not pair may be the wrong generation for this model.
- Wi-Fi or Cellular
- Wi-Fi or Wi-Fi+Cellular (eSIM) versions — a 'no signal' on a Wi-Fi model is expected; cellular needs a data plan.
- Symptom boundary
- This record covers Apple iPad Pro and iPad Air (M4 Pro and M2 Air, 11 and 13 inch) when it microphone is quiet, muffled or not working. A different symptom on the same hardware, or this symptom on a different Apple product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
- !A local voice note is silent or badly distorted with the case off, the ports clear and no accessory connected — that is the microphone hardware.
- !The fault began after liquid exposure and has not improved after several days of drying.
- !The fault began after a drop, which can displace the microphone or its flex connection.
- !Every microphone on the phone fails simultaneously, which points at the audio subsystem rather than one component.

Common questions
My Apple Pencil won't pair with my M4 iPad Pro.+
Check the Pencil generation — the M4 iPad Pro works with the Apple Pencil Pro and the USB-C Apple Pencil, but NOT the 1st- or 2nd-generation Apple Pencil, which will not pair. If you have the right Pencil, magnetically attach it to the side to pair and charge (Apple Pencil Pro/2nd-style), make sure Bluetooth is on, and restart the iPad. A wrong-generation Pencil is the most common 'won't pair' cause after a model change.
