You raise your Galaxy Buds3 Pro to take a call, start talking, and the person on the other end says they cannot hear you, or your voice sounds muffled, cut out, or drowned in background noise. It is a frustrating problem on earbuds built specifically for clear calls, since the Buds3 Pro use internal and external microphones for Active Noise Canceling and AI-based call noise reduction that is supposed to minimize background noise so your voice is heard. The good news is that most microphone trouble comes from debris, a temporary software glitch, or a Bluetooth hiccup, and you can usually fix it yourself in a few minutes. The steps below start with the easiest and safest options and move toward a full reset and Samsung support, so you only escalate if you have to.
One quick note before you begin. The Buds3 Pro are controlled by the Galaxy Wearable app on a paired Samsung Galaxy or Android phone or tablet. They can pair to an iPhone over Bluetooth as a basic headset, but the Galaxy Wearable app is not available on iOS, so a few of these fixes apply only when the buds are connected to an Android device.
Clear out the microphone openings first
Earwax, lint, or dust lodged in the microphone hole can physically block your voice from being picked up, and this is by far the most common and least risky cause. Samsung recommends cleaning the microphone hole, speaker, and air duct regularly to remove earwax or other debris. It costs nothing and often solves the problem outright, so it is the right place to start.
- 1.Use a clean, dry, soft brush or cotton swab.
- 2.Gently clear the microphone hole, the speaker, and the air duct of any earwax or debris.
- 3.Do not use a sharp object or excessive force, and keep the buds dry throughout.
Sharp tools and hard pressure can damage the mesh and the sensitive components behind it, so go slowly and gently. Once the openings are clean, make a quick test call and see if your voice comes through clearly before moving on to anything more involved.
Give the earbuds a quick restart
If cleaning did not help, a simple restart clears the kind of temporary glitches that can leave the microphone unresponsive. This is the official manual restart for the Buds3 Pro, and it does not erase any of your settings, so it is completely safe to try.
- 1.Insert both earbuds into the charging case.
- 2.Close the lid.
- 3.Wait at least seven seconds, then remove the earbuds.
The buds reconnect to your phone automatically after you take them out. Before you do this, make sure the case itself has enough battery, since a near-empty case will not give the buds the moment they need to power-cycle properly.
Confirm your pinch and call controls are responding
Sometimes the microphone is fine, but it seems broken because the touch controls are not registering, so calls drop or seem unresponsive. On the Buds3 Pro, a single pinch answers or ends a call and also plays or pauses audio, while swiping along the touch area adjusts the volume. Run through these gestures during a call to confirm they are doing what you expect.
If the touch controls are not responding at all, the touch feature may be locked. Samsung notes that if touches are not recognized, the Block touches option may have been turned on by accident, so open the Galaxy Wearable app on your paired Galaxy or Android device and tap the switch next to Block touches to turn it off. Once touch is working again, your call controls and the behavior tied to them should respond normally.
Update the earbud software
Outdated firmware is a frequent and overlooked cause of call and microphone problems, and Samsung pushes fixes through software updates. Updating requires the Galaxy Wearable app, so this step applies when your buds are paired to a Galaxy or Android phone or tablet. Make sure both earbuds are charged and connected before you begin.
- 1.Place the earbuds in the charging case with the lid open and connected to the app.
- 2.Open the Galaxy Wearable app.
- 3.Tap Earbud settings.
- 4.Tap Earbuds software update.
- 5.Tap Download and install.
Keep the case lid open and the buds near your phone until the update finishes so it does not get interrupted partway through. After it completes, place a fresh test call to see whether the microphone behaves any differently than it did before.
Forget the buds and pair them again
A corrupted or confused Bluetooth pairing can route call audio incorrectly or break the microphone connection entirely. Removing the pairing and setting it up fresh clears that out. This step removes the buds from your phone, so you will need to pair them again afterward. The exact steps depend on whether you are using a Galaxy phone or an iPhone.
On a Galaxy phone, go to Settings > Connections > Bluetooth, tap the gear icon next to the Buds, and choose Unpair. Then put the buds back in the case and either close and reopen the lid, or press and hold the Connect button on the bottom of the case for more than 3 seconds to enter pairing mode. When the pop-up appears, tap Connect.
On an iPhone, remove or forget the buds in Settings > Bluetooth, then reconnect them. Open the case with the buds inside (press the case button for about 3 seconds if needed), turn Bluetooth on, and tap the Buds3 Pro under Other devices. Remember that the Galaxy Wearable app is not available on iOS, so on an iPhone you are limited to this basic Bluetooth pairing.
Reset the earbuds to their default settings
If the microphone still fails after cleaning, restarting, updating, and re-pairing, a factory reset returns the buds to their default state and clears deeper software faults. A reset erases your saved settings and removes the existing pairing, so you will need to set everything up again afterward. This is done through the Galaxy Wearable app, so the buds must be connected to the app on your Galaxy or Android device for this method to work. Follow the on-screen instructions as you go.
- 1.With the buds connected, open the Galaxy Wearable app.
- 2.Tap Earbud settings.
- 3.Tap Reset.
- 4.Tap Reset again to confirm.
After the reset completes, you will need to set up your preferences again and confirm the buds are paired to your phone. Test the microphone with a call once everything is reconnected.
When to bring in Samsung Support
If the microphone still does not work after you have cleaned the openings, restarted, checked your controls, updated the firmware, re-paired, and performed a factory reset, the problem is most likely hardware rather than software. At that point, Samsung advises visiting a Samsung Service Center or contacting Samsung Support for further assistance. A technician can inspect the microphones directly and determine whether the buds need repair or replacement, which is something no at-home step can do.
Before you go, it helps to have run through every fix above so you can tell support exactly what you have already tried. That usually speeds up the diagnosis and avoids repeating steps you have already covered.
Frequently Asked Questions
Do the Galaxy Buds3 Pro actually have a microphone?
Yes. The Galaxy Buds3 Pro use internal and external microphones for Active Noise Canceling and for AI-based call noise reduction, which uses machine learning to minimize background noise so your voice is heard. Because they rely on real microphones for calls, a microphone can genuinely stop working, which is why Samsung publishes dedicated mic troubleshooting for them.
Why does my voice sound muffled on calls even when the mic seems to work?
A muffled or weak voice is often caused by debris in the microphone hole, speaker, or air duct, so clean those openings first with a clean, dry, soft brush or cotton swab. If cleaning does not help, restart the buds and update the earbud software through the Galaxy Wearable app, since outdated firmware can affect call quality.
Can I fix microphone problems on an iPhone?
Partly. You can clean the microphone openings, restart the buds by placing them in the case and closing the lid for at least seven seconds, and forget and re-pair them through Settings > Bluetooth on the iPhone. However, firmware updates and the factory reset require the Galaxy Wearable app, which is not available on iOS, so those steps need a paired Galaxy or Android device.
Will a factory reset delete anything important?
A factory reset returns the earbuds to their default settings and removes the current pairing, so you will need to set up your preferences and pair them again afterward. To do it, open the Galaxy Wearable app, tap Earbud settings, tap Reset, then tap Reset again to confirm and follow the on-screen instructions. The buds must be connected to the app for this method to work.
How do I restart my Galaxy Buds3 Pro?
Insert both earbuds into the charging case, close the lid, wait at least seven seconds, and then remove them. They reconnect to your phone automatically. Make sure the case has enough battery before you try, since a depleted case will not let the buds power-cycle correctly.
