You can hear the caller perfectly, but they cannot hear you — or your voice keeps cutting in and out. If you have been searching for “earbuds mic not working on calls” fixes, the problem is frustrating but almost always fixable. The microphone on a pair of earbuds is a tiny component that depends on clean mic holes, correct phone settings, and a stable Bluetooth connection, and a fault in any one of those breaks your calls.
This guide walks you through the fixes in the order you should try them, from thirty-second checks to deeper resets. They apply to true wireless earbuds from every major brand sold in India, on Android, iPhone, or laptop.
| Symptom | Likely Cause | Fix to Try First |
|---|---|---|
| Caller hears nothing at all | Blocked mic hole or wrong input device | Clean mic holes, check input settings |
| Voice is muffled or distant | Wax or debris over the mic | Clean the microphone holes |
| Voice cuts in and out | Weak Bluetooth connection | Re-pair and reset the earbuds |
| Mic works in one app but not another | App permission missing | Check mic permissions per app |
| Mic fails on every device | Hardware fault | Replace or claim warranty |
Earbuds Mic Not Working? Quick Checks Before You Troubleshoot
Before you change anything, run through these quick checks. First, make sure the earbuds are the active audio device for the call — on phones, tap the audio output indicator on the call screen and confirm your earbuds are selected. On laptops, check the earbuds are set as both output and input.
Second, check the charge. A bud with a nearly dead battery can keep playing audio while its mic misbehaves. Third, confirm you have not muted the mic by accident — many earbuds mute with a long-press or triple-tap that is easy to trigger when adjusting the fit.
Fix 1: Clean the Microphone Holes
The microphone holes on earbuds are tiny — often just pinholes on the stem or the outer face of the bud — and they clog easily with earwax, dust, sunscreen, and pocket lint. A blocked mic hole is the single most common reason an earbuds mic stops working on calls, and the voice symptom is distinctive: you sound muffled, distant, or like you are talking through a wall.
Find the mic holes on your model — usually pinholes on the stem or the outer face of the bud. Inspect them under good light, then sweep debris away with a dry, soft-bristled brush. For stubborn grime use a dry cotton swab — never poke a pin into the hole, and never use water or liquid cleaners, which can damage the mic membrane inside.
After cleaning, make a test call and ask the other person how you sound. If your voice is suddenly clear, that was the whole problem.
Fix 2: Check Mic Permissions and Default Input Device
If your earbuds mic works in phone calls but not in WhatsApp, Zoom, or Teams, the calling app probably lacks microphone permission. On Android, long-press the app icon, open App info, go to Permissions, and make sure Microphone is set to Allow. On iPhone, go to Settings, scroll to the app, and toggle the Microphone switch on.
On a laptop, the issue is usually the default input device. In Windows sound settings, check that your earbuds are selected as the input — Windows sometimes switches to the laptop’s built-in mic. On a Mac, open System Settings, then Sound, and confirm the earbuds are the chosen input.
Also check the Bluetooth profile on computers. When earbuds connect in “headset” mode for calls, audio quality drops by design — that is normal Bluetooth behaviour, not a fault.
Fix 3: Re-Pair and Reset the Earbuds
A corrupted Bluetooth pairing can leave audio working while the mic channel fails. On your phone, go to Bluetooth settings, find your earbuds, and choose Forget or Unpair. Put both buds in the case, close the lid for ten seconds, then re-pair from scratch.
If that does not help, reset the earbuds themselves — usually holding the touch areas on both buds for 8–15 seconds until the lights flash. For brand-by-brand reset steps, see our one earbud not working fix guide. When re-pairing, keep other previously paired devices’ Bluetooth turned off so the buds do not half-connect to a laptop in the next room.
Fix 4: Test on a Different Device or App
This step tells you whether the problem is the earbuds or the phone. Pair your earbuds with a different device and make a test call. If the mic works fine there, the fault lies in the original device’s settings or a specific app.
Similarly, test across apps on the same phone. If the mic works on regular calls but fails on WhatsApp, the issue is app-specific — reinstalling the app or clearing its cache resolves most of these cases. If the mic fails on every device and every app, the earbuds themselves are at fault.
Fix 5: Update the Earbud Firmware
Manufacturers fix mic-related bugs in firmware updates more often than people realise — issues like the mic dropping mid-call, aggressive noise cancellation cutting out your voice, or the mic channel failing after a phone OS update. Open your brand’s companion app with both buds connected and check for pending firmware updates.
Install the update exactly as the app instructs, keep the phone nearby, and do not interrupt the process. After the update completes, test with a real call rather than just a voice recorder, since calls use a different Bluetooth profile than recording apps.
If your earbuds have no companion app, check whether the manufacturer offers a desktop updater. Budget models without any update path skip this fix — which is one reason mic reliability is worth weighing when you buy. Our TWS buying guide explains what separates reliable models from the rest, and if you are ready to upgrade, look at boAt alternatives with better mic performance for calls.
When It’s a Hardware Fault
If the mic fails on every device and app after cleaning, re-pairing, resetting, and a firmware update, you are almost certainly looking at a hardware fault — a dead mic capsule, a cracked joint from a drop, or water damage.
Check your warranty first. Most earbuds sold in India include a one-year warranty covering mic failure under normal use. Do not open the earbuds yourself — that voids the warranty. If out of warranty, a replacement usually makes more sense than repair, and mic quality varies enormously between models, so check call-quality reviews before your next purchase.
FAQs
Why can I hear callers but they cannot hear me on my earbuds?
This usually means the mic channel has failed while audio playback still works. The most common causes are blocked microphone holes, the wrong input device selected, or a corrupted Bluetooth pairing. Clean the mic holes first, then re-pair.
How do I clean my earbuds microphone?
Locate the tiny mic holes on the stem or outer face of each bud, then sweep them gently with a dry soft-bristled brush or dry cotton swab. Never poke anything sharp into the holes and never use water or liquid cleaners.
Why does my earbuds mic work on phone calls but not on WhatsApp?
That points to an app permission problem. On Android, check the app’s permissions and set Microphone to Allow; on iPhone, toggle the Microphone switch for that app in Settings. Reinstalling the app also fixes many such cases.
Does resetting earbuds fix microphone problems?
Often, yes — if the cause is a corrupted Bluetooth pairing or a desync between the buds. Reset the earbuds, delete the old pairing from your phone, and pair again from scratch. It will not help if the mic hole is physically blocked or the mic hardware has failed.
When should I replace earbuds with a broken mic?
Replace them when the mic fails on every device and app after cleaning, re-pairing, resetting, and a firmware update. Check your warranty first — most pairs sold in India carry one year of coverage for exactly this kind of fault.
