Xiaomi wireless headphones have long become a standard accessory for millions of users, but even experienced owners sometimes have a panic: βWhy donβt the headphones charge?β or βHow do I know if they are connected to charging at all?β. This is especially true for models with minimalist design, where there are no bright LEDs or loud beeps.
The problem is compounded by the fact that different Xiaomi series (from the budget Redmi AirDots to the premium FlipBuds Pro) use different charging indicators: somewhere it is a flashing LED, somewhere it is a voice alert, and in some cases, headphones silently βabsorbβ energy without giving any external signs. In this article, we will analyze all possible ways to check charging, including hidden functions and diagnostics through the mobile application.
If your headphones don't respond to the case or charger, don't be quick to blame the manufacturer -- 80 percent of the time, the problem is in trivial things, from oxidized contacts to improperly inserted cable, and we'll show you how to avoid typical errors and determine exactly if charging is going on.
For convenience, we have divided the instructions by model and display type. If you don't know the exact model of your headphones, use the section on model definition at the end of the article.
1. Standard charging indicators: what do LEDs mean
Most Xiaomi headphones are equipped with LED indicators that signal the status of charging, but their behavior can be radically different even for devices of the same generation.
β A white/blue LED (blinks or burns constantly) is the most common indicator, depending on the model, it can mean:
- π Constant light β headphones are fully charged (e.g. Redmi AirDots 2).
- π Slow flashing - the charging process is underway (Mi True Wireless Earphones 2).
- β‘ Fast flashing β low charge level of the case (less than 10%, you need to connect the case to the outlet).
β οΈ Note: Xiaomi Buds models 3/3T The pro indicator on the case does not flash while charging the headphones β it only lights up when the case is connected to the power source.
π΄ Red LED is less common, but its meaning is unambiguous:
- π Constant red: Critical charge level (less than 5%).
- π Flashing red β charging error (check contacts or cable).
π‘
If the indicator on the case does not respond to the connection of headphones, try to reboot the case: remove the headphones, hold the button on the case for 10 seconds, then insert the headphones back.
2.Audio cues: what the headphones say
Many Xiaomi models provide audible alerts to charge, which is especially useful if the case is in the bag or you can't see the indicator.
π΅ Short sound signal when placing headphones in the case:
- π One signal β headphones started charging (Mi AirDots Pro 2, Redmi Buds 3 Lite).
- ππ Two signals β the headphones are already charged (charge level) >80%).
- πβ Long signal. + pause β charging error (check contacts or dust them out).
π£οΈ Voice prompts (in English or Chinese) are found in premium models:
- ποΈ "Charging (Xiaomi FlipBuds Pro).
- ποΈ "Battery Low - Low Case Charge.
- ποΈ "Connected β headphones connected to the case (not to be confused with charging!).
β οΈ Note: In Redmi AirDots 3 and later, audio signals can be turned off in the settings of the Mi Home or Xiaomi Wear app. If the Suddenly headphones stop "talking", check these settings.
3. Verification through a mobile application: hidden data
The most reliable way to know the status of charging is to use official Xiaomi apps, which not only show the current level of charge, but also display charging speed, battery temperature and even predict the remaining time to full charge.
π± Verification annexes:
- π Mi Home β universal for all Xiaomi devices (including headphones).
- βοΈ Xiaomi Wear β specialized for wearable electronics.
- π§ Mi Earphones β for some models (e.g. Mi AirDots Pro).
π How to check charging through the application:
- Open the app and find your headphones in the list of devices.
- Go to the "Battery Status" or "Charging" section.
- Look at the charging graph -- if it's moving to the right, it's going.
π What do the icons in the app mean:
| Badge | Description | Action. |
|---|---|---|
| β‘ | Charging is coming. | Leave the headphones in the case. |
| π | Charging complete. | We can use it. |
| β | Charging error | Check the contacts/cable |
| π₯ | Battery overheating | Let's cool down for 10-15 minutes. |
β οΈ Note: Mi Home sometimes displays false charging status (e.g. 100% at real 80%).To update the data, remove and paste the headphones back into the case.

4. Contact Diagnostics: Why Headphones Don't Charge
If the lights aren't on, if the sound isn't on, if the app isn't showing you charging, the problem can be mechanical contacts, which is the most common cause of "imaginary" malfunction.
π What to Check First:
- π§² Magnetic contacts -- headphones have to stick tightly to the case. If they're hanging around, the contacts don't touch.
- π Contact contamination - dust, pile or oxidation block charging. Clean with an alcohol napkin.
- π Damage to spring contacts in the case (often broken when falling).
π οΈ How to Clean Contacts:
- Use a cotton swab dipped in isopropyl alcohol (not vodka!).
- Gently wipe the gold contacts on the headphones and inside the case.
- Let dry 5-10 minutes before connecting.
β οΈ Warning: Do not use needles or metal objects to clean! this can damage the protective coating of the contacts, which will lead to corrosion.

5. Checking the charger and cable
Often users blame the headphones, although the problem lies in the power supply or cable. Xiaomi headphones are sensitive to the quality of charging, and not every adapter will fit.
β‘ Requirements for charger:
- π Power: minimum 5W (5V/1A). For fast charging (e.g. Xiaomi Buds) 3 Pro) need an adapter 10W+.
- π Type of cable: original USB-C (For new models, or Micro-USB (older ones), cheap cables may not transmit charging data.
- π± Compatibility: Some headphones refuse to charge from βnon-compatibleβ adapters (for example, from Samsung or Apple).
π How to check the cable and adapter:
- Connect the headphones to another charger (such as from a smartphone).
- Try another cable (preferably original).
- Check if the indicator on the case burns when connecting to the outlet.

π‘
If the case is charging, but the headphones are not, try plugging the case into the socket for 1-2 hours. Sometimes the case does not give power to the headphones if its own charge is below 20%.
6. Resetting settings and firmware: when nothing helps
If all previous methods failed, the problem may be a software failure, in which case a reset or firmware update will help.
π How to reset Xiaomi headphones to factory settings:
- Put the headphones in the case.
- Hold the touchpad on both headphones for 15 seconds (for AirDots) or the button on the case (for FlipBuds).
π² Update the firmware through the application:
- π Open Mi Home β pick out the headphones β "Firmware update".
- π₯ If the update is available, connect the headphones to the case and wait for the completion (do not interrupt the process!).
- β οΈ After the update, be sure to restart the case (hold the button for 10 seconds).
β οΈ Attention: Setting reset wipes out all the mated devices, and after the procedure, the headphones will have to be reconnected to the phone.
π‘
If the headphones don't charge after reset, the problem is likely hardware (damaged battery or charging controller).
7. How to determine the model of headphones if you do not know it
If you are not sure what your model is, use these methods of identification:
π Where to look for a model:
- π§ In the case, in small print on the back (for example, TWSEJ04LS For Redmi AirDots 2).
π Comparative table of popular models:
| Model | Charging indicator | Sound signal | Case connector type |
|---|---|---|---|
| Redmi AirDots | Red/white LED | 1 signal when charging | Micro-USB |
| Mi True Wireless 2 | White LED (blinks) | Voice "Charging" | USB-C |
| Xiaomi Buds 3 Pro | RGB-indicator | 2 signals when fully charged | USB-C (Fast Charging) |
| FlipBuds Pro | Hidden indicator (LED inside) | Sound + vibration | USB-C |
π‘ If you find the model code on the case (for example, MDZ-35-DB), Type it into a search engine β the first results will show the exact model.
