Why Xiaomi Headphones Cannot Be Connected β and How to Fix It
Xiaomi wireless headphones are some of the most popular on the market due to the price/quality ratio, but even they sometimes refuse to connect to a smartphone. If you turn on Mi True Wireless, Redmi Buds or AirDots headphones for the first time, or you encounter a synchronization error, do not rush to carry them into the service. 90% of the time the problem is solved in 5 minutes on your own.
The main reasons why Xiaomi is not connected via Bluetooth: Redmi Buds 4 Pro or Mi True Wireless 3 is not determined by the phone?Maybe you missed the reset step or incorrectly activated pairing mode. Next, detailed instructions for all models, including the rare cases when the headphones "can't see" each other.
Step 1: Check the charge and turn on the headphones
Before you try to connect to your phone, make sure the headphones are charged and on. Even if the indicator on the case is green, it does not guarantee 100% battery life on the headphones themselves.
- π Case charge: open the lid - if the indicator does not light up, connect the case to the charging on the 10-15 minute.
- π§ Headphone charge: pull them out of the case, each should flash a white or red light bulb (depending on the model.
- π Reset connection: for Redmi Buds models 3/4 Mi True Wireless 2 press the button on the case 10 seconds until the indicator flashes red and white.
If the headphones are zero, it can take up to 20 minutes for them to gain enough charge to turn on. Some models (such as the Xiaomi Buds 4) do not turn on when charged below 5% - this is deep discharge protection.
β οΈ Warning: If the indicator on the case flashes red for more than 5 minutes after charging, this is a sign of a battery failure.
Step 2: Activate the pairing mode
To make Xiaomi headphones visible to the phone, you need to put them in pairing mode.
| Model headphones | How to activate pairing mode | Indication |
|---|---|---|
| Redmi Buds 3 / 4 | Press the button on the case for 3 seconds (with the lid open) | White light flashes fast |
| Mi True Wireless 2 | Press the touchpad on both headphones for 5 seconds | Red and white light alternate |
| Xiaomi Buds 4 Pro | Open the case cover - automatic pairing mode | White light flashes for 30 seconds |
| Redmi AirDots | Take the headphones out of the case and press the button on each for 3 seconds. | Red light is replaced by white light |
If the light doesn't flash white, the headphones aren't ready to plug in.
- Put the headphones back in the case and get them back.
- Press the reset button (if any) on the back of the case.
- Connect the case to charging for 1 minute, then try again.

For Android:
- Open Settings β Bluetooth.
- Turn on Bluetooth (slider at the top).
- In the list of available devices, find the name of your headphones (for example, "Redmi Buds 4" or "Mi True Wireless SE").
- Click on the name and the pairing will begin.
For iOS (iPhone):
- Go to Settings β Bluetooth.
- Make sure Bluetooth is on.
- In the "Other devices" section, your model will appear - tap it.

Xiaomi smartphones with MIUI 14+ have a βFast Connectionβ feature: open the notification curtain β press the Bluetooth icon β select βAdd deviceβ.
Step 4: Solving Connection Problems
If Xiaomi headphones donβt connect despite all the effort, check out these points:
- π± Reset Bluetooth settings on your phone: Settings β System system β Reset β Reset network settings (Android) or Settings β Mainstream β Reset β Reset network settings (iOS).
- π Update the firmware of the headphones: some models (for example, Xiaomi Buds 4 Pro) require an update through the Mi Home app or Xiaomi Wear.
- π οΈ Check physical damage: inspect contacts in the case and on headphones for oxidation or dirt (wipe with alcohol).
- π΄ Disable other Bluetooth devices: sometimes smartwatches, fitness bracelets or speakers conflict.
For Redmi Buds 3 Pro and later, there is a hidden reset function: put the headphones in the case, close the lid, then press the button on the case for 15 seconds until the indicator goes out and flashes red again. This will reset all the settings to the factory.
β οΈ Note: If one of the headphones doesn't work after you connect (for example, only the left one plays), it may be a synchronization problem between them.
What if the headphones are connected but there is no sound?
Step 5: Customize sound and control
After successful connection, it is recommended to configure:
- π΅ Equalizer: In the Mi Home or Xiaomi Wear app, select a preset (e.g., Bass or Clear Highs").
- ποΈ Gesture control: set up double-touch to play/pause or call a voice assistant.
- π Noise reduction: for models with ANC (For example, Xiaomi Buds 4 Pro) turn on the mode in the headphone settings.
- π Microphone: Choose which headphone to use for calls (left/right/both).
For models with LDAC support (e.g. Mi True Wireless 3), enable the codec in your phone's Bluetooth settings: Settings β Bluetooth β Settings (cog) β Audio Quality β LDAC.
π‘
Use the original Xiaomi app for headphones β it gives access to hidden settings, such as adjusting the sensitivity of the microphone or updating the firmware.
Step 6: Update the headphone firmware
If Xiaomi headphones are unstable (communication is broken, sound is distorted), check the relevance of the firmware.
- Install the Xiaomi Wear app (for MIUI) or Mi Home (for other Android/iOS applications).
- Connect the headphones to the phone via Bluetooth.
- Open the app β find your headphones in the list of devices.
- If an update is available, a notification will appear β follow the instructions on the screen.
The update process takes 2-5 minutes. Don't interrupt the connection or close the application, otherwise the headphones may stop turning on. For Redmi Buds 4 and later, the firmware update is only available when the case is charged > 50%.
Frequent mistakes and their solutions
Letβs look at the typical problems and specific actions to address them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Headphones are not on | Battery discharged or case damaged | Place the case on charge for 30 minutes; check contacts |
| They're connected, but the sound is interrupted. | Interference from other devices or outdated firmware | Update the firmware; disable other Bluetooth devices |
| Only one earpiece works. | Dissynchronization or contamination of contacts | Reset the settings; wipe the contacts with alcohol |
| Not determined by the phone. | The pairing mode is not activated | Press the button on the case/earphones until white light flashes |
If neither of these methods worked, check the headphones on the other phone. If the problem persists, this is an excuse to contact the service center (especially if the device is warranty).
