iPhone 6s: caller can't hear
The client complained that during calls he was barely audible, especially in the car. We replaced the microphone on the lower flex cable and checked calls and recording — the connection is clear.
Callers say they can't hear you on iPhone 6s? We'll replace the microphone in 20–40 minutes and lock the price and selected part in your receipt.

A failing microphone is easy to blame on the network, as callers keep asking you to repeat, videos record silently and Siri goes unanswered.
During a normal call your voice sounds muffled or cuts out, while you hear the other person just fine.
Clips record the picture but the voice is very quiet or missing, even though the camera itself works well.
Voice activation stays quiet and dictation in Messages misses most of the words you speak.
Speakerphone calls and voice memos come out noisy, with crackling that gets louder when you talk.
We name the final cost after a free diagnostic — call us or send a message on WhatsApp.

The final amount depends on which microphone has failed and on the type of part you choose.
Every microphone is tested, the case is opened, the seat cleaned, the new part fitted, the phone reassembled and a final test call made.

We compare the bottom, top and rear microphones in a call, a video and Voice Memos to pin down the fault.

The display module is lifted with care and the battery is disconnected, so no flex cable gets damaged.

Dust and corrosion marks around the microphone and connector are removed so contact stays reliable.

The chosen microphone or its flex cable goes in, and we check that the connector is seated firmly.

The display returns to place, the seal is refitted and every screw goes back to its original hole.

Your voice is checked in a regular call, on speakerphone and in a recorded video before pickup.
You get clear sound on calls and recordings, backed by our warranty.
Price for my modelOriginal and aftermarket parts differ in sound quality and lifespan, and the choice stays with you.


We look for the cause before replacing anything, and the part itself is your choice, whether you come on a weekday or at the weekend.
Our work comes with a warranty up to 1 year, so if the same fault returns on our side, we look at it again.
The service has worked for 11 years and knows the usual faults of older iPhones inside and out.
The microphone on a sixth-generation phone is swapped by experienced technicians, not by a random soldering amateur.
We explain the original versus aftermarket difference in plain words before work starts and never push.
If the fault sits on the board rather than in the microphone, we say so up front and you avoid needless costs.
We take phones on weekdays and at weekends too; exact opening hours are listed on the contacts page.

The client complained that during calls he was barely audible, especially in the car. We replaced the microphone on the lower flex cable and checked calls and recording — the connection is clear.
The whole journey — from message to finished phone. We give you the old part.
Book a replacementYou message us on WhatsApp with the model and what happened — we give you the price and time. Or you come in without an appointment.
We check voice recording in calls and Voice Memos: sometimes the mesh or the board is at fault, not the microphone.
We note the model, the part (original or aftermarket), the price, the timeframe, and the warranty.
We open the factory packaging in front of you and check the number against the receipt.
We install a new microphone or the flex with it and seal the case with water-resistant adhesive.

iPhone 6s Microphone Replacement in Astana with a Free Check
For iPhone 6s microphone replacement in Astana, iServices starts with a free 15-minute check in front of you, so the engineer confirms which microphone failed before work begins. We replace the lower charging-flex assembly or upper microphone flex, show the new part in factory packaging, and back the job with a warranty up to 1 year.
An iPhone 6s carries three separate microphones, and the symptom you notice points straight at the one that has failed. A quick self-test narrows the search to a single assembly ahead of any parts order.
| Microphone | Where it sits | What it handles | Quick test |
|---|---|---|---|
| Lower | Charging-flex assembly by the Lightning port | Normal calls, audio notes | Record in Voice Memos |
| Upper | Flex near the earpiece | Speakerphone, noise cancelling | Switch to speaker on a call |
| Rear | Flex beside the main camera | Video sound | Film a clip on the rear camera |
A clear recording in Voice Memos while callers still cannot hear you points to the charging-flex path rather than the capsule itself, so the diagnosis changes what gets swapped. A dead recording in every app, with video clips also silent, usually means the bottom assembly is gone. When only speakerphone and selfie clips fail, the upper unit near the earpiece is the suspect, and the rear unit shows up in video sound alone. Running all four steps in a single sitting takes about a minute and removes guesswork ahead of any parts order. Bring the phone in and we will repeat the same check in front of you, free of charge, and show you which component is at fault.
On the iPhone 6s the lower microphone is soldered to the charging-flex assembly, so an iphone 6s microphone replacement in Astana usually means renewing the whole lower unit rather than a single capsule.
On the iPhone 6s the lower microphone is soldered to the charging-flex assembly, so we replace that whole unit rather than a single capsule. The same ribbon carries the Lightning port, the 3.5 mm headphone jack and the connector that links it to the board, and they all share a single strip of copper traces. When that strip cracks from cable stress or a drop, the microphone is often the first thing to go silent, yet the port is usually already on its way out. A worn ribbon shows up first as an intermittent charge or a cable that only works at an angle, so treat those early signs as a warning ahead of the capsule dropping out entirely. We swap the whole piece because re-soldering a lone capsule onto fatigued traces rarely holds.
| Part on the assembly | What it does | How we check it |
|---|---|---|
| Lower microphone | Voice on normal calls | Voice Memo playback |
| Lightning port | Charging and data | Plug in a cable |
| 3.5 mm jack | Wired headphone audio | Play through headphones |
| Ribbon connector | Links the assembly to the board | Full call check |
Sometimes sound disappears not because of a microphone but because of the audio codec on the logic board. The difference shows in the accompanying symptoms, before anyone opens the phone.
We run the free 15-minute check in front of you, testing each microphone path separately ahead of deciding whether the assembly or the logic board is at fault. The engineer switches between the bottom, front and rear microphones during a call, a voice memo and a video recording, then compares the readings against the speaker and earpiece output. If every path is dead at once, the audio codec on the board goes under the microscope — we handle board work in-house rather than passing it on. If the chip is involved, the job moves under the microscope and takes longer, so knowing this early stops you from paying for a flex that was never the problem.
Not every quiet microphone needs a new part. Dust, a case, a settings slip or a splash of liquid can all produce the same muffled symptoms, yet each cause calls for a different response.
After liquid contact we treat the case as urgent, because corrosion spreads and a microphone that still works today can fail within days. The iPhone 6s has no factory water protection, unlike the iPhone 7, 8 and 8 Plus, which carry an IP67 rating, so moisture reaches the bottom assembly quickly through the very opening that carries the microphone. That is why a diagnostic after a spill sometimes takes up to two days to show the full picture — corrosion under the shield can stay hidden at first and only surface once the board dries. We open the device, clean the contacts and inspect the ribbon under the microscope ahead of deciding whether a replacement is even needed. Do not charge a wet phone; bring it in, and the engineer inspects it in front of you at no charge.
The visit starts with a photo on WhatsApp and ends with the two of us listening to the phone together. Most microphone work is done while you sit in the waiting area.
| Stage | What happens | Time |
|---|---|---|
| First contact | Send a photo on WhatsApp, get a quote | Within 5 minutes |
| Diagnostics | Engineer checks the device in front of you | 15 minutes |
| Paperwork | Price, part, turnaround and warranty on the receipt | 2 minutes |
| Repair | New component shown in factory packaging, then fitted | 20–40 minutes |
| Handover | Sound checked together, old part returned | About 10 minutes |
Ahead of handover we run a 32-function inspection of about 10 minutes, and microphones are part of it alongside calls, speakerphone and video. The engineer works through the list with you at the counter: you speak into the phone, switch to speaker, record an audio note, then test the front camera and the touchscreen. You walk out with the warranty card covering a full year, the old component in a bag and the receipt that matches what you signed. Checking the device in your own hand, with your own SIM and apps, catches anything a bench check misses and settles the question on the spot.
A quick recap of what decides the outcome: which microphone failed, what the lower assembly carries, and how the result is confirmed before the phone leaves the bench.

Ask a questionThe small hole next to the rear camera houses the microphone used when filming with the main camera. Calls rely mostly on the bottom microphone instead. So silent videos with normal calls point to the rear microphone.
Usually not, because on the iPhone 6s the bottom microphone sits on the same cable as the Lightning port and the headphone jack. The assembly is replaced as one part, so you get a fresh charging connector at the same time.
Yes, a poorly fitting case can cover the bottom holes or the opening near the camera. Take the case off and record a voice memo to compare. If the sound becomes clear, the phone is fine and only the case needs changing.
First check that the feature is on in Settings and retrain your voice there. If Siri still does not react and dictation records poorly, one of the microphones may be clogged or failing. The engineer tests each one separately.
Yes, water droplets in the mesh distort the sound until they dry. Wipe the phone and leave it in a warm, dry place without blowing hot air into the holes. If crackling stays, the contacts may have started to corrode.
Record a voice memo, film a short clip with each camera and call someone on the earpiece and on speakerphone. Ask the person if your voice sounds clear. You go through these tests together with the engineer.
У нас в офисе три таких ноутбука, один сломался. Неделю лежал без дела, теперь хрипит динамик. Бақмухаммед С. отсоветовал дорогой ремонт, предложил простой. Выдали номер заказа и сказали, как отслеживать. Нужна была новая деталь: дисплей. 10 500, и горонтия в комплекте. Пришлось самому напомнить о себе. Скажу знакомым. Функционирует, тьфу-тьфу.

Работаю рядом, заехала в обед. Проблема — хрипит динамик. Про i service узнала от коллеги из офиса. Работает, даже лучше прежнего.
Искала, где есть оригинальные запчасти, а не «как оригинал». Проблема — хрипит динамик. Вернули — проверила, всё ок.
Проблема — хрипит динамик. Вернули — проверила, всё ок. Экран яркий, батарея держит
У нас в офисе три таких ноутбука, один сломался. В командировке достал, а у него хрипит динамик. Сейчас роботает без нареканий
Сдала iPhone 17 Pro Max мастеру. Проблема — хрипит динамик. Ғалымжан С. отсоветовал дорогой ремонт, предложил простой. Привезла на такси, приняли без вопросов. Нужна была новая деталь: плата. Заплатила 36 500 тенге, и всё. Достойно сделали. Внешне не видно, что разбирали.

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.

What “maximum capacity” means, why the phone shuts down in the cold, and how long a new battery lasts.

Power it off, skip the rice, and get the board checked before corrosion starts. Here is the short version of the first 30 minutes.

Most charging faults come from the cable, the port or the battery. Here is how to find the cause and get a free check.
