The situation when Xiaomi wireless headphones suddenly stop working is familiar to many owners of the Mi and Redmi ecosystem. The music just played clean, and after a minute the device stops responding to commands or does not turn on at all. Users often panic, believing that the gadget has failed and requires expensive repairs in the service center. However, in most cases, the problem lies in software failures or improper synchronization, which can be fixed on their own.
In this article, we will take a closer look at all possible causes of malfunctions, from simple battery discharge to complex Bluetooth protocol conflicts, learn how to properly reset settings, why it is important to clean charging contacts, and how to distinguish a defect from a software glitch. Competent diagnosis will save you time and nerves, allowing you to return your loved ones. TWS-Headphones to life in a matter of minutes without a visit to the workshop.
The main reasons for the lack of sound and connection
The first thing that users face is the lack of sound or the inability to connect to a smartphone. Often the culprit is not the Xiaomi device itself, but a crowded Bluetooth cache on the phone or a conflict of profiles. When you try to pair headphones with a new device, the old profile can block the correct operation, requiring complete removal from the list of conjugated gadgets.
Also, consider the physical distance and the presence of obstacles. Bluetooth signal has a limited range, and if the phone is in the far pocket of jeans, and you are in an area with a lot of Wi-Fi routers, there can be interference. Radio interference is a common problem in apartment buildings or offices, where the density of wireless networks is over the top.
⚠️ Note: If the indicator on the case flashes red when removing the headphones, this may indicate a critically low charge or oxidation of contacts, and not a break in the speaker.
Another common reason is the desynchronization of the left and right earphones. TWS-One channel is a master transmitter, and if this communication is broken, the sound can only come from one ear or be completely absent.
Problems with charging and indicators
If your Xiaomi wireless headphones are out of action and don't respond to the onset, check the charging system first. Often the problem is trivial: the contacts on the earpiece itself or inside the case have oxidized. Dust, pile from your pocket and moisture create a non-conductive film that blocks the energy supply. Regularly cleaning contacts with a dry cotton swab solves the problem 90 percent of the time.
It's important to pay attention to the behavior of LED lights. If you put it in a case, you don't light up, you try to move the headphone. This will indicate that the magnets are not tightly attached. In some models, such as the Redmi AirDots or Mi True Wireless Earbuds Basic 2, the magnets can weaken over time, and the earphone simply does not fall into the charging zone.
- 🔋 Check the charging cable: use the original wire or quality analogue with a current of at least 1A.
- ⚡ Clean contacts: gently wipe the golden pads on headphones with an alcohol napkin.
- 🔌 Check the case: make sure the case itself is charged as it acts as Power Bank for headphones.
And don't rule out battery wear, Li-ion batteries lose capacity over time, and if the headphones are in active use for several years, they can run out of power. 15-20 minutes that users mistakenly take for a breakdown.
💡
Use a soft dry toothbrush to clean the speaker mesh and charging contacts – a cotton pile can get stuck in shallow holes and a brush will clean the dust efficiently.
Failures in Bluetooth and pairing
When Xiaomi headphones turn on but the phone doesn’t see them or writes a connection error, the problem is often the overcrowded memory of the smartphone’s Bluetooth module. The system can “remember” too many old devices, which prevents new connections from working properly, in which case you need to clear the list of conjugated devices.
Older Bluetooth 4.0 phones may not work properly with newer headphones that support 5.2 or 5.3, especially when using high-quality codecs like AptX or LDAC.
Sometimes it helps to switch flight mode. Turn on the flight mode for 10 seconds, then turn it off and try to find the headphones again. This action restarts the phone's radio module, resetting accumulated connection errors.
Instructions: How to perform a full reset (Hard Reset)
If software bugs become critical, you need to reset your headphones to factory settings, which removes all saved profiles and resets the internal logic of the device. The algorithm may differ slightly from one model to another, but the general principle is the same.
First, place both earbuds in the charge case and leave the lid open. Make sure the case is charged. Then find the function button on the case case case case (usually round and located between the indicators or on the end). Press this button for 10-15 seconds until the indicator flashes white or orange (depending on the model).
☑️ Reset algorithm TWS Xiaomi
For models without a physical button on the case (such as some versions of the Mi AirDots), the reset is done through touch panels. You need to remove the headphones, turn them off (clutching the sensor for 5 seconds), and then pinch the sensors on both headphones simultaneously for 20-30 seconds until they flash red.
| Model headphones | Resetting method | Indication of success | Retention time |
|---|---|---|---|
| Redmi AirDots 2 | The button on the case | Orange blinking | 10-15 sec. |
| Mi True Wireless 2 | The button on the case | White flashing | 10 seconds. |
| Mi AirDots Basic | Headphone sensors | Red flashing | 20-30 seconds |
| Xiaomi Buds 3 | The button on the case | Indicator goes off/lights up | 10 seconds. |
After a successful reset, the headphones will go into pairing mode. Remember to remove the old device from the Bluetooth list on the phone before reconnecting, otherwise the conflict will persist.
Program conflicts and smartphone settings
Remember, the smartphone itself can be the source of the problem. There are power saving settings in Android and iOS operating systems that can aggressively limit the operation of Bluetooth devices. If you have Ultra-energy saving mode on, the system can block the background work of the headphones, considering them to be resource consuming.
Also check the developer settings. The hidden Android menu has options that affect Bluetooth, such as the Bluetooth AVRCP Version or the Bluetooth Codec. Changing these settings can either fix or make things worse.
Hidden Bluetooth settings in Android
Updating the firmware of the headphones through the Mi Wear or Xiaomi Earbuds app can also fix software bugs. Manufacturers regularly release patches that improve connection stability and noise cancellation.
Hardware malfunctions and physical wear
When all software methods are exhausted and the headphones are not working, there is likely a physical breakdown. The moisture protection in Xiaomi's budget models is often nominal.
Mechanical damage, such as falling from a height or impact, can move the plumes inside the body or damage the speaker's membrane. If you hear wheezing, crackling or sound only at a certain frequency, chances are the speaker is physically damaged.
⚠️ Attention: Opening Xiaomi headphones almost always leads to leakage and loss of warranty. If the device is warranty, do not try to repair it yourself.
Another rare but possible problem is that the charge controller inside the case fails, in which case the headphones can run on their own residual charge, but they stop charging in the case, and the only way to diagnose this unit is with a multimeter in the service center.
💡
If after resetting, cleaning contacts and reconnecting to another phone headphones do not work – likely hardware breakdown requiring a battery replacement or speaker.
