Nobody can hear you on iPhone 7 calls — we'll fit a new microphone within 20–40 minutes, then check calls, Voice Memos and video with you.
Your voice disappears unexpectedly: callers keep asking you to repeat, videos hiss or stay mute, and voice memos record nothing.
The other person keeps asking you to repeat or hangs up, though your signal shows full bars.
They hear you, but as if from the next room, so you must speak louder and closer to the bottom edge.
Clips come out mute, or background whistling and crackle mix into your voice.
A recording exists but your voice is missing; the meter runs on screen while the audio track stays almost flat.
The price depends on whether one microphone is fixed or the whole bottom unit is needed.

The technician gives the final amount after testing the sound inputs and inspecting the cable.
We test every sound input, then clean the openings and contacts and replace the microphone or its cable.
We check calls, speakerphone, video recording and voice memos to see where the voice drops out.
We remove the display, unplug the battery from the board and lift out the shield plates, touching nothing else.
We clear the grilles and contact pads, because sometimes that alone brings the voice back.
If the part is faulty we fit a new one and make sure the contacts seat without any skew.
Seals return and the screen is secured so dust and moisture stay away from the microphone.
We make a test call and a recording, then let you listen to the result and confirm clean sound together.
A technician leads the repair, and we listen to the result with you.

iPhone 7 Microphone Replacement in Astana for Calls, Video and Siri
For iPhone 7 microphone replacement in Astana, iServices fixes a mic that stopped passing your voice, first checking whether the fault is the microphone or the audio codec. Diagnostics are free and take 15 minutes in front of you, most jobs finish in 20–40 minutes while you wait, and the warranty runs 1 year.
Three microphones sit inside an iPhone 7, and the one that has failed determines both what you notice and how much work the fix involves. Here is how to name the faulty unit yourself in about a minute.
| Microphone | Its location | What it handles |
|---|---|---|
| Bottom | Next to the Lightning port, on the charging flex | Your voice in a normal call |
| Top (front) | By the earpiece at the top edge | Speakerphone, noise cancelling, front-camera video |
| Rear | Beside the main camera lens | Sound for rear-camera video |
Record a voice memo, film a short clip on both cameras and make one call on speaker — the pattern of what fails points straight at the guilty microphone. The voice memo captures the bottom unit alone, a front-camera clip tests the top unit together with noise cancelling, and a rear-camera clip isolates the module beside the lens. Try asking Siri something and also record a voice message in a messenger: both use the same bottom microphone as a call, so if both fail, that confirms the issue. If the voice memo is silent but speakerphone works, the bottom microphone is the suspect; if only video sound is missing, look at the rear unit. If you are in Astana, iPhone 7 microphone replacement starts with this same check at the counter. Write down which tests failed prior to travelling across the city.
The same muffled call on an iPhone 7 can come from dirt in the mesh, a paired headset or a dead microphone. We sort the likely cause from the symptom before any part is quoted.
| What you notice | Probable reason | What we do |
|---|---|---|
| Callers never hear you, speakerphone works | Bottom microphone | Replace the charging flex |
| Sound muffled but steady | Dirt in the mesh | Clean the opening and retest |
| Audio cuts in and out mid-sentence | Flex connector wear | Reseat or replace the flex |
| Only video sound is missing | Rear microphone | Replace the rear flex |
| Siri and voice notes dead, calls fine | App permissions or a headset | Check settings first |
Rule out a wireless earpiece still connected, a blocked microphone permission and a case covering the bottom opening before any part is swapped. Open Settings, check Privacy and Microphone access for the calling app, then forget every paired device in the Bluetooth list. A cover or screen protector that overlaps the bottom grille can deaden the sound without a single broken component, so take it off and record a voice note to compare. A hard restart clears a stuck sound session more often than people expect, and it costs nothing to try before booking a slot. If callers still report silence after these three checks, the fault sits in hardware and an engineer can confirm it on the spot during free diagnostics, which takes about 15 minutes.
Owners often ask why one silent microphone turns into a whole part swap. The answer sits in how the lower section of the iPhone 7 is built, and what else rides on the same component.
On iPhone 7 the bottom microphone is soldered onto the charging assembly, so we replace the whole unit rather than a single microphone capsule. Along the bottom part of the housing sits a single flex assembly combining the Lightning port, the contact for the lower speaker and the tiny microphone opening. Apple bonded these parts tightly to save internal space, and the microphone sits too close to the connector traces to be swapped on its own. A single failed capsule therefore means a full assembly replacement, which is why the job is listed as a microphone replacement rather than a soldering micro-repair. This is a common reason a call microphone goes quiet while everything else still works. If your phone already struggles to charge, mention it when you book — the same flex explains both symptoms.
A fresh charging assembly restores the call microphone, the Lightning port and the lower speaker contact in one go, and we test all three before handover. The microphone capsule itself is a tiny MEMS component near the port opening, and it picks up sound for calls, video and audio memos. The Lightning connector handles charging and data, while the lower speaker contact feeds the loudspeaker grille on the bottom edge. Because all three sit on the same board, a worn or corroded part can drag them down together. At handover we run the microphone through a recording test, check charging with a cable and confirm the lower speaker output. If charging was already flaky before the microphone died, the assembly was the common cause all along, not two separate faults — worth telling the engineer so the diagnosis points straight at the board.
There is a board-level defect on the iPhone 7 that looks just like a mic that has died. Here is how to tell the two apart ahead of opening the phone.
If the Speaker button is greyed out on calls, a voice memo captures no sound and the phone sticks on the logo, the culprit is the board's audio codec rather than the microphone. When the codec fails, the handset stops routing audio across every path at once, so the interface greys out the button instead of passing sound through. The same chip handles call sound, Voice Memos and speakerphone, which is why three separate symptoms appear together rather than a single one. A long boot that stalls on the Apple logo fits the same picture. We confirm the codec on the bench before quoting a part, because replacing the lower assembly on such a phone changes nothing and leaves the fault untouched. Our engineers fix the board under a microscope, and that work takes one to three days instead of the twenty to forty minutes for a part swap.
| Sign | Microphone fault | Codec fault |
|---|---|---|
| Speaker button in calls | Works normally | Greyed out |
| Voice Memos | Silent or muffled | Records nothing |
| Speakerphone | Often still works | Dead as well |
| Boot time | Normal | Hangs on the logo |
| Fix | New lower assembly | Board repair under a microscope |
We follow the entire path from your initial WhatsApp photo to when the device leaves our bench, including how the terms are recorded on the receipt and how the sound is tested alongside the engineer.
You send a photo via WhatsApp, an engineer responds within 5 minutes with a price and a free slot, and most microphone repairs are completed in 20–40 minutes while you wait. The free diagnostics take 15 minutes in your presence, even if you choose not to proceed with the repair, and the engineer shows you what is broken rather than just describing it. If you are unable to come in, a courier can be arranged, and 72% of repairs finish while the customer waits in the seating area with coffee and Wi-Fi. Before work begins, the price, the part, the turnaround and the warranty are set on the receipt, so nothing changes once the phone is open.
At handover we run a 32-function check of about 10 minutes and test the microphones with you, then hand back the receipt, the warranty card and the old part. The engineer walks through the cameras, speakers, charging and network alongside the voice recorder and Siri, so a silent mic cannot slip past. The new part is shown in its factory packaging before installation, and 64% of our customers pick an original part over an aftermarket one. Warranty lasts up to 1 year, and the old part goes home with you as proof of what was removed from the phone. Ahead of leaving, make sure your data is backed up and your account is signed in, so the device is ready to use the moment you switch it on.
A brief summary of the checks that determine whether a microphone job is simple, a flex replacement or a board problem, and what to verify before leaving the counter.

Ask a questionMainly the bottom one, next to the Lightning port. The others help with noise reduction, speakerphone and video. So when people cannot hear you on a regular call, the bottom microphone is checked first.
Yes, the bottom microphone sits on the same cable as the port. If charging is also unstable, both faults usually have one cause. Replacing that cable fixes both at once.
Yes, Lightning EarPods have their own microphone on the cable. They are a good temporary solution for calls. If people hear you well through them, the phone's microphone is confirmed as the cause.
Often it is a weak network rather than the microphone. Record a voice memo: if it sounds clean, the microphone is fine. If the recording is also distorted, the microphone needs checking.
Video calls rely on other microphones than the bottom one used on regular calls. If one of them is clogged or faulty, only some modes lose sound. The engineer tests each microphone separately.
Yes, the engineer tests them in front of you and shows which one has failed. The check covers calls, recordings and video. Only after that is the price for the repair written on the receipt.
The difference is not always visible, but it can be checked. An original panel is the one the manufacturer installs; an aftermarket copy costs about 35% less.
