The situation when TWS-Headphones stop working in pairs, is one of the most common problems owners of budget acoustics from Xiaomi. Users often face the fact that after extracting from the case, only one channel works, or both channels turn on, but the sound goes exclusively in one ear. This is puzzling, since the model is positioned as a device that works on the principle of “take and use".
The reason is that the Bluetooth modules are out of sync within the headphones themselves. Redmi AirDots (including the Basic, S and 2 versions) use True Wireless Stereo technology, where one channel is the master and the other is the plume. If communication between them is broken, the smartphone sees them as two different devices or connects to only one. Fortunately, 90% of the time the problem is solved by software without going to the service center.
In this article, we will explore in detail the pairing recovery algorithms, forced reset methods, and nuances that are rarely mentioned in official manuals, how to interpret the flashing of indicators correctly, and why ordinary cleaning of contacts sometimes helps.
💡
The main reason for desynchronization is the simultaneous inclusion of both headphones outside the charging case or the discharge of one of the channels below the critical level.
Diagnosis: why headphones stopped working in pairs
Before you start to actively restore, you need to understand the nature of the failure. Often users start to reset when the problem lies in the banal discharge of the battery of one of the modules. If the left or right channel is completely discharged, it may have gone into deep sleep and not react to the commands of the master. Check the indicators: if they are placed in the case, they do not light up, it may have oxidized contacts.
Another common cause is "memory conflict," and a smartphone could remember the headphones as two separate devices: Redmi AirDots and Redmi. AirDots_R. In this case, the phone’s operating system tries to connect to both channels independently, ignoring their internal logic of working in conjunction, which often happens after an update to the Android or iOS operating system, when Bluetooth protocols get new priorities.
⚠️ Note: If one of the headphones flashes red more often than the other, this may indicate a critically low charge of this particular module, even if the second shows a full charge.
Also, consider the physical condition of the device. Moisture, falling, or just being in your pocket for a long time without a case could lead to the accidental pressing of the touchpad, in which case the earphone could go into pairing mode and start looking for another device, ignoring its "partner." For accurate diagnosis, try to play the sound and check the balance of channels in the phone settings.
Basic cleanup of the Bluetooth list on a smartphone
The first and most important step before any reset is to completely clear the connection history on your mobile device. As long as the phone remembers the old configurations, it will try to restore communication using old protocols, interfering with the reconnection process. Go to your smartphone's Bluetooth settings and look up Xiaomi Redmi AirDots devices list.
Don't just shut down. You need to run a "Forget the device" or "Cancel pairing" command. If you see two identical names or names on the list with the L and R prefixes, delete them all. After that, it is recommended to completely turn off the Bluetooth module on the phone for 10-15 seconds to reset the cache of network services.
- 📱 Open Bluetooth settings and delete all Redmi AirDots records.
- 🔄 Reboot your smartphone to update network drivers.
- 🔋 Place the headphones in the case and close the lid for 10 seconds.
This will create a blank slate for later synchronization, and ignoring this step will cause the phone to continue to see the headphones as unsynchronized devices even after they are successfully reset, and it is important to make sure that no other device that the headphones have been connected to before (tablet, laptop, phone) is within a 5-meter radius.
Instructions for the complete reset (Hard Reset) of headphones
The most effective way to reconnect between channels is to perform a hard reset. The procedure may vary slightly depending on the model (Basic, S, 2), but the general principle remains the same: You will need to hold the touchpads of both headphones simultaneously for a long time.
Place both earbuds in the charge case, then remove them. Wait for them to turn on (usually a red light light). Now press and hold the touch zones on both earbuds at the same time. You need to keep them clamped for about 20 seconds. First, the lights will flash red, then go out, and again light up red. It is the second sunbath that signals a successful reset.
☑️ Checklist of resetting settings
After the lights go out a second time, put the headphones back in the case. Give them 5-10 seconds to stabilize the charge, then retrieve. Now they must automatically find each other. The indicator of the correct connection is when one earpiece (usually the right one) slowly flashes white (search mode), and the second (left one) does not blink or blinks very rarely, waiting for a connection to the master.
⚠️ Warning: Do not open your fingers when holding your sensors, even if the headphones are vibrated or sounded, and the reset process will be interrupted if you release the sensors ahead of time.
Synchronization subtleties: how to know if they are connected
Many users mistakenly believe that if both earbuds flash white, they are ready to go. In fact, in TWS mode, only one channel should be in active search mode (fast flashing white), while the second channel should behave differently, if both blink, then they are not connected to each other, and each is looking for the phone separately.
In an ideal scenario, after reset, the right headphone (Master) will flash white quickly, waiting for a connection to the smartphone. The left headphone (Slave) at this point either does not burn at all, or flashes very slowly and dimly, signaling that it is waiting for a connection with the master. Only after connecting to the phone can both channels start working synchronously.
| Status of the indicator | Channel Right (Master) | Left Channel (Slave) | Status |
|---|---|---|---|
| Phone search | Fast flashing white | Slow blinking/Switched off | Norma (ready to mate) |
| Razsynchronization | Fast flashing white | Fast flashing white | Mistake (reset needed) |
| Charging. | Burning red. | Burning red. | Norma (in case) |
| Charged. | It's not burning. | It's not burning. | Norma (full charge) |
If you see both channels flashing white, repeat the reset procedure, but this time try to pinch the sensors a little longer — up to 25-30 seconds. Sometimes the controller takes longer to clear the error buffer. Also try to first connect only the right earphone to the phone, and keep the left one in the case at this moment, and only after successfully connecting the phone to the right channel, remove the left one.
The secret of double touching
Problems with charging and contact
Often, software failure is a consequence of a physical charging problem, and if one of the headphones is not fully charged in the case due to poor contact, it will shut down early and the communication between the channels will break, and visually this may be invisible, since the indicator on the case can indicate that charging is underway.
Check the metal contacts on the headphones themselves and inside the case, often accumulating earwax, dust or oxidized metal. Use a cotton swab slightly soaked in alcohol (isopropyl) to clean the contacts carefully, trying not to damage the speaker grid.
- 🧹 Wipe the contacts with alcohol to remove oxides.
- 🔍 Check if the headphones are deep in the case.
- ⚡ Make sure the case itself is charged at least 30 times%.
It also matters the pressing force. Sometimes you just have to press the earpiece in the case with your finger to make sure it's on the magnets and the contacts are closed. If the headphone indicator doesn't light up when you put it in the case, then there's no current, and it's useless to reset, the device is just discharged.
💡
Use an eraser to clean your contacts. A regular school eraser is great at removing oxides from metal pins without leaving a pile, unlike cotton wool.
Alternative methods and application work
If standard methods don’t work, you can try using third-party Bluetooth device management apps like AndPods or MaterialPods (for Android) to see the charge level of each channel separately and sometimes force reconnection. However, for Redmi AirDots models, the official Mi Home app often doesn’t see headphones, as they belong to an ecosystem that doesn’t require complex setup.
There's also a mono-mode method. Try plugging only one headphone (right) into your phone. Play the sound, make sure it works. Then, without turning off Bluetooth, put the working earphone in the case, and leave the second (left) outside. Remove the right one again. Sometimes this sequence causes the master channel to re-interview the environment and find the salvo.
⚠️ Warning: Don't try to connect your headphones to two different phones at the same time while you're setting up.
In extreme cases, if nothing helps, you can try connecting your headphones to a device with a different operating system (for example, if you configured on Android, try iOS or Windows). Different Bluetooth stacks can initiate handshake processes between TWS channels in different ways, which sometimes shakes up their internal logic.
