Why does one Xiaomi AirPods headphone stop working?
The situation when one of the headphones Xiaomi AirPods Pro, AirDots or another model suddenly stops making sound, familiar to many users. the reasons can range from a banal battery discharge to serious hardware failures. Most often the problem arises from software failures, clogging of the speaker or mechanical damage after a fall. For example, in models Xiaomi Buds 3 Pro often fails contact group in the charging case, which leads to improper charging of one of the headphones.
It’s important to understand that Xiaomi wireless headphones are complex devices with a microphone, Bluetooth module, battery and speaker. Any of these components can fail. According to service center statistics, 60% of the time the problem is solved software (reset, reconnect), 30% by cleaning or replacing consumables (such as speaker grids), and only 10% require deep repair. If your earphone stopped working after updating the MIUI firmware, it’s likely the software is to blame – this is a typical problem for devices connected to Xiaomi smartphones based on HyperOS.
Before you bring your device to the service, try to diagnose the problem yourself. Start with simple steps: check the charge, reset the headphones, clear the contacts. In most cases, this is enough to return the sound. If the earphone is not detected by the system or flashes in red, it is a signal of more serious malfunctions.
Step 1: Check basic settings and connections
The first thing you need to do is make sure that the problem is not with your smartphone or PC settings, and sometimes the sound goes missing because of a random change in Bluetooth settings or volume balance.
- 🔊 Sound balance: On Android or iOS, go to the sound settings and make sure the left-right-earphone balance slider is in the middle. On Xiaomi way: Settings → Sound. → Stereo balance.
- 📱 Bluetooth Connection: Open a list of connected devices and check if both earphones are displayed. If one is missing, try reconnecting.
- 🔋 Battery charge: In the Mi Home or Xiaomi Wear app, check the charge level of each headphone.
- 🎧 Mono/stereo mode: Some applications (such as Zoom or Discord) can force the headphones to mono mode.
If you're not solving the problem at this point, you go to hardware diagnostics, and note that if the earphone doesn't turn on at all (it doesn't blink, it doesn't make sounds), it's probably a battery or power card problem, and then you'll only be able to disassemble it or call the service.
Step 2: Resetting headphone settings to factory
One of the most effective ways to get back up is hard reset, which clears all settings, including device pairing data, and is suitable for most Xiaomi AirPods, but may be slightly different across generations.
For reset, perform the following actions:
☑️ How to Reset Xiaomi AirPods
Once reset, the headphones will go back to factory settings, if the problem was a software failure (for example, after updating the firmware), this should help. If the reset did not work, the reasons lie deeper — perhaps in damage to the Bluetooth module or a break in contacts.
⚠️ Attention: On Xiaomi Buds 4 Pro models, the reset button is hidden under a rubber plug on the back of the case.Do not use sharp objects to press - this can damage the micro-switch.
Step 3: Cleaning contacts and speakers
One common cause of silence in one earpiece is contamination of the speaker or contacts, and dust, earwax, or moisture can block sound or disrupt the connection to the case.
- 🧻 Cotton swabs (preferably with a plastic rod).
- 💧 Alcohol wipes or isopropyl alcohol (70% and higher).
- 🔍 Lupa (optional, for accurate cleaning).
- 💨 A compressed air canister (for blowing out dust).
Clean it carefully:
- Spread it with a cotton swab dipped in alcohol. Don't press too hard, the membrane is very fragile.
- Contacts on the headphone and in the case: Oxidation or dirt on metal pads can interfere with charging and synchronization. Use an eraser for careful cleaning.
- Microphone holes: A clogged microphone can cause the earphone to become deaf. Blow the holes with compressed air.
If you don't have a sound after cleaning, try to wipe the contacts with a stationery eraser, which will remove the oxides, and in 40% of cases, this procedure solves the problem with the "dead" earphone.
💡
To prevent contamination, keep headphones in a case and avoid use in dusty areas (for example, in a construction site or workshop).
Step 4: Checking the charging case
A case is not just a case, it's a charger synchronizing device, and if it's faulty, the headphones may not charge or turn on. Here's how to diagnose a case problem:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Case is not charging from the cable. | Faulty. USB-power-port | Try another cable/charging. If it doesn't work, repair the board. |
| The headphone doesn't charge in the case. | Oxidation of contacts or failure of the charging pad | Clean your contacts with alcohol. If it doesn't work, replace your contact group. |
| Case discharges in a few hours | Wear of the case battery | Replacement of the battery (in the service or on its own) |
| Case indicator flashes red | Short circuit or controller error | Resetting the case (hold the 30 sec button) or repairing |
To check if the problem earphone is charging, leave it in the case for 10-15 minutes, then pull out and see the charge level in the Xiaomi Wear app. If the charge has not changed, the contacts or the headphone battery are likely to malfunction.
⚠️ Note: Do not use fast charging with more power to charge the case 10 W -- this can damage the power controller. 5V/1And.
Step 5: Diagnostics of hardware breakdowns
If all the software methods have been tried and the earphone still doesn't work, it's a hardware malfunction.
- 🔊 Speaker break: The sound is missing completely, but the earphone is determined by the system and charged. Often occurs after a fall or heavy mechanical impact.
- 📡 Bluetooth module malfunction: The earphone flashes but does not connect to any device.Can be caused by overheating or a power surge.
- 🔋 Battery failure: The earphone discharges quickly or doesn't turn on even after charging.The battery can swell - it's dangerous!
- 🛠️ Board damage: The earphone does not respond to any action, does not blink, does not charge.
For self-diagnosis, disassemble the headphone (carefully tucking the case with a plastic card) and examine:
- Integrity of flexible plumes (often detached when falling).
- Battery state (blown, leakage of electrolyte).
- The presence of burned elements on the board (resistors, capacitors).
If you are not sure about your skills, it is better to contact the service. The cost of repairing Xiaomi AirPods varies from 800 rubles (replacement of the speaker mesh) to 3000 rubles (replacement of the board).

Step 6: Alternative repair methods
If standard methods don’t help, you can try less obvious solutions:
- 🔄 PC firmware: For some models (e.g. Xiaomi AirDots Pro 2), there are informal firmware that can restore performance. Use MiFlash or Fastboot utility.
- 🔌 Connecting to another device: Sometimes the headphone doesn't work with one smartphone, but it connects to another correctly.This helps identify a problem with the phone's Bluetooth module.
- 🛒 On AliExpress or in specialized stores you can buy speakers, batteries or boards for self-replacement. For example, a speaker for Xiaomi Buds 3 Pro costs about 500 rubles.
- 📞 Appeal in support of Xiaomi: If headphones are guaranteed, contact the official service via the Mi Community app or the website service.xiaomi.com.
To run headphones through a PC, you may need to unlock the bootloader. Be careful: informal firmware can deprive you of warranties or permanently disable the device.
💡
Before firmware, be sure to check the compatibility of the version of the software with your headphone model. Incorrect firmware can lead to the "bricking" of the device.
