If people cannot hear you clearly through your TWS earbuds, first separate a microphone problem from a call, app or Bluetooth-routing problem. Make one short test call, check that you are not muted, confirm the earbuds are selected for call audio, then compare the same earbuds in a phone voice recording or another calling app. Change one thing at a time. This quickly shows whether the issue follows the earbuds, one app, the phone settings or the network.
Do not start by buying another pair or repeatedly resetting everything. A simple before-and-after test reduces uncertainty and gives you a clearer answer with less effort.
First identify what the other person actually hears
Ask one person to describe the problem in a specific way:
- Can they hear nothing at all?
- Is your voice very quiet, broken or distant?
- Does the problem happen only in one app?
- Can you hear them normally while they cannot hear you?
- Does switching to the phone microphone make your voice clear?
That last comparison is especially useful. If the phone microphone works in the same call but the earbud microphone does not, focus on Bluetooth call routing, permissions, fit, cleanliness and re-pairing. If both sound poor, the app, network or phone may be the better place to investigate.
9 checks when the TWS earbuds microphone is not working
1. Check mute and the call screen
Look at the active call screen and confirm that mute is off. If the calling app has its own microphone control, check that as well. Tap once and wait for the icon to update instead of pressing repeatedly.
2. Confirm the earbuds are selected for call audio
During the call, open the audio-output control and select the connected Bluetooth earbuds. A phone can remain paired while routing the call through its own speaker or microphone. If your Bluetooth settings show separate options for calls and media, make sure call audio is enabled for the earbuds.
3. Compare a call with a short voice recording
Use the phone's normal voice-recording app, where available, and record one short sentence with the earbuds connected. Then record the same sentence with Bluetooth disconnected. Keep your position and speaking volume similar.
If the recording is clear but a particular calling app is not, inspect that app's permission and audio settings. If every test made through the earbuds is unclear, continue with the physical and connection checks below.
4. Check microphone permission for the calling app
Open the phone's app-permission settings and confirm that the calling app has microphone access while you use it. Grant only the permission needed for calls. If permission is already enabled, close and reopen the app before testing again.
5. Check earbud position and speaking conditions
Wear the left and right earbuds on the correct sides and seat them comfortably without forcing them deeper. Do not cover the outer surface with a hand, cap, scarf, hair or helmet strap during the test. Speak in a normal voice in a quieter place first; this gives you a useful baseline before judging performance in traffic or wind.
If the earbuds also feel loose, use our TWS earbud fit checklist.
6. Inspect visible openings safely
Disconnect the earbuds and inspect their exterior under good light. If you can see lint or residue around an opening, use only a clean, dry, soft method on the exterior. Do not insert pins, blades or cotton stems into small openings, and do not pour liquid or cleaner onto the earbuds.
Follow the detailed safe TWS earbuds cleaning guide before doing more than a light exterior wipe.
7. Test another app or call type
Make one test in another calling app or use a normal phone call if available. Keep the same earbuds and phone. If only one app fails, update or review that app's microphone, Bluetooth and call settings rather than resetting the earbuds immediately.
8. Restart the connection cleanly
End the call, place the earbuds in their charging case, turn Bluetooth off and on, then reconnect. Restart the phone if the audio route remains confused. After reconnecting, make one new call before changing another setting.
9. Re-pair only after the simpler checks
If mute, routing, permissions, position, cleaning, app comparison and restart do not help, remove the earbuds from the phone's saved Bluetooth devices and pair them again using the product's normal instructions. Avoid random long-press or factory-reset sequences because controls vary by model.
For a controlled re-pairing sequence, see TWS earbuds not pairing: safe fixes.
A five-minute microphone test
- Call one trusted person from a quiet room.
- Confirm mute is off and select the Bluetooth earbuds for call audio.
- Say the same short sentence twice: once through the earbuds and once through the phone.
- Record the sentence in a voice app with and without Bluetooth.
- Test one different calling app.
- Write down which combination sounded clear.
This small comparison turns “the mic is bad” into a more useful finding such as “only one app fails,” “the call was using the phone,” or “the problem follows the earbuds across every test.”
What should you avoid?
- Do not poke small openings with metal tools.
- Do not pour water, alcohol or cleaner onto the earbuds.
- Do not test several phones, apps and settings at the same time.
- Do not assume louder earbud volume will make your microphone louder.
- Do not keep using earbuds that show swelling, visible damage, liquid inside, a burnt smell or unusual heat.
- Do not promise that a reset will repair physical damage.
Which Problem Solvify TWS option suits calls?
The U39 Premium Wireless TWS Earbuds listing specifically describes the earbuds for everyday listening, calls and travel, with clear sound for calls and music plus fast pairing with compatible devices. At publication, the product was active, priced at PKR 1,999 and had 500 units in inventory.
The Air 31 Wireless TWS Bluetooth Earbuds listing describes wireless stereo sound, a compact charging case, a lightweight comfortable fit and battery use for lectures and travel. At publication, it was active, priced at PKR 1,799 and had 500 units in inventory. Its current listing does not provide a separate microphone specification, so confirm any model-specific call requirement before ordering.
If calls are your main use, U39 is the clearer shortlist from the currently verified descriptions. If lightweight everyday listening and travel are the priority, compare Air 31 as well. Review both in the Electronics collection and check the live product page before checkout because price and availability can change.
Frequently asked questions
Why can I hear the caller but they cannot hear me?
The earbuds may be connected for listening while the call is muted, the app lacks microphone permission, or the phone is using a different audio route. Check mute, call output and permissions before re-pairing.
Why does the microphone work in one app but not another?
The failing app may have different microphone permission, call-audio or Bluetooth settings. Compare the apps under the same conditions and review the failing app first.
Does earbud volume control microphone volume?
Usually, listening volume changes what you hear rather than what the other person hears. Use a call and recording comparison to diagnose the microphone path instead of simply raising playback volume.
Can dirt make calls sound unclear?
Visible residue around an exterior opening can interfere with normal use, but clean only with a dry, soft and non-invasive method. Never insert tools or liquid into an opening.
Should I reset TWS earbuds immediately?
No. First check mute, call routing, app permission, fit, cleanliness, another app and a normal restart. Re-pairing is a later step because it can erase a working connection without fixing the actual cause.
Can wind or traffic make the microphone seem faulty?
A noisy environment can make comparison difficult. Establish a baseline in a quiet room, then test the normal environment. Do not infer a product defect from one outdoor call alone.
What if newly delivered earbuds fail every microphone test?
Keep the box and accessories, note the phone and apps tested, and save short test details. Contact Problem Solvify within seven days of delivery with order details and clear product photos; the request will be reviewed under the refund policy. Use the verified contact page for support.
Use evidence before replacement
The best order is: mute, call routing, recording comparison, app permission, fit, dry exterior inspection, another app, restart, then re-pair. If the problem remains across every controlled test, share those results with support. You will have a clearer case and will avoid replacing a working product for an app or routing problem.
