The situation where your favorite wireless headphones suddenly stop responding to commands is familiar to many users of the Xiaomi ecosystem: You take the device out of the case, but instead of the usual sound signal, you hear silence or see the lack of connection on the smartphone screen, which is annoying, especially if the gadget was urgently needed to call or listen to music on the road.
The reasons for this behavior can be in both the banal discharge of the battery and in the complex software failures of firmware. Often users are faced with the fact that one headphone is working and the second is silent, or the device simply does not enter the pairing mode.
In this article, we will look at all possible breakdown scenarios and methods for fixing them, we will look at the algorithms for resetting settings, the features of Bluetooth modules and the nuances of charging contacts, and understanding these processes will help you reanimate your gadget without going to the service center.
Problems with charge and case contacts
The most common reason why TWS-Xiaomi headphones stop turning on, which is not chargeable. But it's not always that you forgot to put the case on the charger. Often the problem is oxidation or contamination of the contact areas. Dust, pile from your pockets and skin fat create an insulating film that prevents the transmission of current.
Visually inspect the metal contacts on the headphones themselves and inside the charging case. If you notice a plaque, gently wipe them with a dry lilac cloth or a cotton swab slightly soaked in alcohol. It is important not to pour liquid on the inside of the case, so as not to damage the electronics.
Sometimes the problem is the charging cable itself or the power supply. Headphones with fast charging support may not behave properly when connected to powerful smartphone adapters. Try using a less powerful current source or charging a case from the battery. USB-port.
💡
Use a toothpick to clean the grooves in the case where the contacts are, but act extremely carefully so as not to bend the spring mechanisms.
If the device is several years old, the battery capacity could critically decline and it stops holding charge even after a long connection to the network, in which case the headphones can show 100% charge, but turn off after 10 minutes of operation.
Bluetooth pairing errors and synchronization problems
The second most popular reason is a Bluetooth connection glitch, and a smartphone can "remember" old connection data that conflicts with the current state of the headphones, often after a phone operating system update or a playback device change.
To solve the problem, you need to complete a cleanup of the list of conjugated devices. Go to your smartphone’s Bluetooth settings, find your Xiaomi Earbuds (or a specific model, for example, Redmi Buds) in the list, and click “Forget the device” or “Cancel pairing.”
If a simple reconnection doesn't help, there may be a disruption in sync between the left and right earbuds. TWS-In systems, one earpiece is often a master transmitter, and if the communication between the two is lost, the sound will come from only one channel or will not appear at all.
☑️ Actions in case of Bluetooth failure
You should pay attention to the Bluetooth version of the module in the phone. Older smartphones with Bluetooth 4.0 can work unstable with new models of headphones requiring Bluetooth 5.2 or 5.3. In such cases, permanent connection breaks or the inability to original (match).
How to perform a full reset (Hard Reset) headphones
When software bugs accumulate, a radical measure is required, Hard Reset, which returns the headphones to factory settings, deleting all temporary files and resetting connection settings. Different Xiaomi and Redmi models may have different processes.
For most touch-sensitive models (such as Mi True Wireless Earbuds Basic 2), the algorithm is as follows: place both earbuds in the case, leave the lid open. Find the function button on the case case case (if any) and press it for 10-15 seconds before the indicator flashes. If the button on the case is not present, press the touch zones on the headphones themselves while in the case for 20-30 seconds.
Mechanical button models, such as some versions of the Redmi AirDots, require sequential pressing, removing the headphones, turning them off (clamping the button for 5 seconds), and then clamping the buttons again for 15-20 seconds until the indicator flashes red several times.
⚠️ Note: During the reset, do not remove the headphones from the case and make sure that at least the case itself remains 20-30% charge, otherwise the process may interrupt and lead to a software failure.
After a successful reset, the indicators should flash white or red (depending on the model), signaling readiness for mode. Now you can re-search the device in the phone. If the reset did not help, the problem may lie deeper in the firmware.
Software failures and firmware updates
Modern Xiaomi headphones are minicomputers with their own operating system. Bugs in firmware can cause freezes when the device is on, but does not respond to touch. Often manufacturers release patches that fix (problems).
To update the firmware, you need to use the official Mi Home or Xiaomi Earbuds app (for global versions). Connect your headphones to your smartphone, open the app and check for updates. The process takes a few minutes, and during this time the case should be charged at least 50%.
Sometimes the headphones fall into a “brick” state after an unsuccessful update or voltage surge, in which case prolonged button retention (more than 40 seconds) or a special combination of taps described in the manual of a particular model helps.
Hidden combinations for resetting
It is important to understand the difference between hardware breakdown and software. If the headphones behave inadequately after flashing and resetting (spontaneously switch off, change the volume), the control controller is likely to be damaged.
Diagnostics of hardware faults
If software methods fail, we need to move to hardware diagnostics. Often users don't notice microcracks on the case or traces of moisture that lead to corrosion of the board. Even sweat drops in sports can eventually destroy current tracks.
Notice the speakers. If the sound is quiet, hoarse, or completely gone in one channel, the speaker membrane may be damaged or contaminated by earwax, carefully remove the mesh (if the design permits) and clean it with a soft brush.
Mechanical damage after a fall is another common cause: a blow can move the plume inside the body or damage the battery. Visually, this is difficult to determine, but if the earphone warms up when charging or emits an extraneous crack, this is a clear sign of an internal circuit.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| The indicator is not on. | Deep discharge or chain break | Leave on charging for 2-3 hours, check the cable |
| Only one works. | Dissynchronization of channels | Full reset of both headphones |
| Quiet Sound / Whackle | Grid pollution or dynamics | Cleaning with alcohol and brush, replacing the net |
| Not holding the charge. | Battery wear (Li-Pol) | Replacing the battery or buying new ones |
If the case or headphones get hot during charging, disconnect them immediately from the network, which may indicate a malfunction of the power controller, which is fire dangerous.
Features of Redmi Buds, Mi True Wireless, AirDots
Xiaomi’s product lines have their own design features, such as the Redmi AirDots series (1 and 2nd generation) infamous for the problem of desynchronization, when the headphones stop “seeing” each other, and it is critical for them to follow the sequence of extraction from the case when first pairing.
More advanced models, such as the Mi True Wireless Earphones 2 Pro or Redmi Buds 3 Pro, feature an Active Noise Reduction (ANC) system. ANC malfunctions can create the illusion of a broken headphone: you hear only background noise or silence, thinking the speaker is broken. Check the noise reduction settings in the app.
Touch Control models often have a sensor dead zone problem after a software update. Sensor calibration is usually automatic, but sometimes a factory reset is required to restore touch panel sensitivity.
⚠️ Note: When buying used headphones Xiaomi pay attention to the version of the region (CN) You can not connect to global management applications without changing the region to Mi Home, which limits the functionality of the system.
Also worth mentioning is the Xiaomi FlipBuds Pro, which has a complex system of microphones. If the interlocutor can not hear you, the problem may not be in the dynamics, but in the mic silenced due to a software error, treated by rebooting.
When it is time to repair or change the device
There are a number of signs that self-repair is impossible or impractical. If after all the procedures of resetting, cleaning and flashing the device does not show signs of life, most likely, a failed chip or battery.
Replacement of the battery in TWS-In the case of headphones, it's a complex process that requires a microscope, a soldering station and fine electronics skills, and the glue that holds the body together often prevents it from opening without damage. 70-80% price of the new device.
If the headphones are on warranty, do not try to open them yourself. the presence of autopsy marks (torn seals, scratches on screws) automatically voids the manufacturer's warranty obligations.
💡
If the headphones are more than 3 years old and the problem in the battery, it is more cost effective to buy a new model than to look for rare components and pay for complex repairs.
If it hits the water (unless the model is IPX4 certified or higher), it is better to put the device immediately in rice or silica gel, but there is little hope of salvation, since the corrosion of the contacts begins instantly.
