Budget but popular owners TWS-Xiaomi headsets often face a situation where one earphone stops hearing another, a common problem that arises from the dissynchronization of Bluetooth modules inside the case. The user can hear sound in only one ear, or devices can’t see each other in the list of available networks.
Fortunately, you can software-based Redmi AirDots or Mi True Wireless Earbuds Basic back up, so you don't have to open the case or go to the service center, and the whole process takes a few minutes, and you force the resets and reconnect the modules.
In this article, we will discuss in detail the algorithm of actions for re-creating a stereo pair, we will look at the nuances of the indicator operation, the correct sequence of clicks and methods for eliminating the typical mistakes that beginners make when trying to “friend” the left and right channels.
Why the headphones stop working in pairs
The main reason for the desynchronization is the disconnection of communication between the headphones themselves, not the phone. TWS-The devices are built so that one headphone (master) connects to the smartphone, and the second (slave) connects to the master.
Often the problem is oxidation of the contacts or different levels of charge. If one earphone was completely discharged and the other was still working, their internal controllers could "lost" each other, and the failure could occur when the modules were removed from the case, when the modules did not have time to hold the initial handshake.
⚠️ Warning: Trying to connect your headphones to your phone before they sync with each other often fixes the error.First, always reconnect within the pair.
Sometimes the fault is software glitches of the smartphone operating system or overcrowded memory of the Bluetooth cache. In rare cases, the cause is physical damage to the antenna inside one of the modules after a fall, but this happens much less often than software conflicts.
Preparation for the synchronization procedure
Before you start manipulating, you have to do a set of preparatory steps, which is a critical step, and ignoring it 80 percent of the time leads to failure, and you have to clear the connection history of your mobile device completely.
Go to your smartphone's Bluetooth settings. Search Redmi AirDots or Mi True Wireless Earbuds on your device list. Click on the gear icon or hold the device name to see the context menu.
- 📱 Select "Forget the device" or "Disable».
- 📴 Turn off Bluetooth on your smartphone completely.
- 🔋 Make sure that both earbuds are in the case and charged.
- 🧹 Clear the list of saved devices if there are old records about these headphones.
Now you need to put both earbuds in a charge case. Make sure they sit tight in their nests. Indicators should light up red to signal the start of charging. If the indicator is not burning, wipe the contacts with dry cloth or cotton swab, perhaps earwax or dust is interfering.
☑️ Pre-reset check
Algorithm of resetting and pairing headphones
There are two main synchronization methods, depending on the firmware version and your AirDots model. The first method is universal for most versions, including Basic, Basic S and 2.
Method one: Double tap. Take both earbuds out of the case. They should catch fire. Quickly press 5 times on the touchpad of each earbud. The headphones should turn off. Then put them back in the case, wait 10 seconds and pull them out again. Now they should enter pairing mode.
Method two: Hold the buttons. Remove the headphones from the case. At the same time, press and hold the touchpads on both earphones for 20 seconds. They can start flashing red, then white. Don't let go of the buttons until you see that the lights have gone out or started flashing at a different frequency.
⚠️ Attention: During reset, the indicators may flash red several times. This is normal. The main thing is to wait until they go out or go into rapid flashing white.
After the reset, the indicators of both headphones should start flashing white quickly, which means they are in search mode for each other. If only one flashes, and the second flashes slowly or does not blink at all, repeat the reset procedure, making sure that you press the buttons at the same time.
What if one earpiece flashes and the other doesn’t?
Status Indication and Signal Decoding
Understanding what the colors and flashing modes of LEDs mean makes it much easier to diagnose. Light indicators are the only way a headset can communicate with a user. Different models may have slight differences, but the basic Xiaomi standard is the same.
Red usually indicates charging or low charge. White signals readiness for connection or active connection. Combinations of these colors and blinking modes give accurate information about the current status of the device.
| Indicator mode | Meaning | User action |
|---|---|---|
| Burning red. | Charging's coming. | Wait for full charge |
| Blinks white (both) | Interconnection mode (search for each other or phone) | Turn on Bluetooth on your phone |
| Blinks white (one) | Searching for a second headphone | Perform a reset settings |
| Burning white. | Successful connection | Use music |
| Blinks red. | Critically low charge | Put it in the case now. |
Notice the blinking frequency. Slow blinking white usually means the earbud is looking for a previously paired device. Fast blinking is a visibility mode for a new connection. The critical point is when both earbuds are flashing white quickly at the same time — this is the perfect moment to turn on Bluetooth on a smartphone.
If the indicators do not light up at all, check whether the protective film is removed from the contacts inside the case (relevant for new devices) and whether the case is charged. The lack of reaction can indicate a deep discharge, requiring 15-20 minutes of charging before first turning on.
Connecting to a smartphone after resetting
Once you've achieved synchronous fast flashing of white on both headphones, you can move to the final stage. Turn on Bluetooth on your mobile device. Don't look for the device in the list right away, give the system a few seconds to scan the ether.
The list of available devices should appear the name Redmi. AirDots_R Mi True Wireless EBs Basic_R. Important: you need to connect to the device with the index R (Right), the left earphone will connect to the right automatically, and in the list of devices it will not appear.
- 🔍 Click on the device name with the end R.
- 🔊 Wait for the “Connected” sound in your headphones.
- ✅ Check the sound in both channels by turning on the music.
- 📶 Make sure that Bluetooth status says “Connected” (not “Connected (media, phone)” for only one channel).
If there are two devices on the list (e.g. Redmi). AirDots_L redmi AirDots_R), It means that the headphones are not synchronized, they see the phone as two independent mono-device, and then you have to remove both devices from the list again and repeat the reset procedure.
💡
If the phone sees two devices, try plugging one in, waiting for the sound, and then the other, but the right thing to do is reset it completely (5 taps or 20 seconds of hold) so that it becomes a stereo pair again.
Common Errors and How to Resolve Them
Even following the instructions, users sometimes run into problems. One of the common mistakes is trying to connect headphones when Bluetooth is active on the phone, which prevents the headphones from finding each other, as they immediately start looking for the last stored device.
Another problem is that the sensor sticks, and if you don't put your finger away immediately after you press it, or if you make it too short, the command doesn't count. You need a clear, confident tap to reset. On models without physical buttons, that requires a certain skill.
⚠️ Warning: Do not try to charge your headphones during the reset procedure if the case is connected to the power supply.Some users note that disabling the case from charging during the reset increases operations.
Also, consider distance. When pairing, keep the headphones close to each other (within 10-20 cm), but not in a case. If they are too far away, they may not "see" each other to create an internal network.
💡
The key to success is to always start by completely removing your device from your phone’s memory and turning off Bluetooth. 90% of failures are due to ignoring this step.
Additional settings and optimization
After successful synchronization, it is recommended to check additional settings. In the Mi Wear or Xiaomi Earbuds app (for some models), you can update the firmware of the headphones. This often solves hidden connection bugs that are not eliminated by a simple reset.
Check the sound balance in your smartphone’s special features settings. Sometimes users accidentally shift the balance slider completely left or right, thinking that the earphone is not working, although the problem is with the Android or iOS settings.
To extend battery life, try not to drain the case to zero. Lithium polymer batteries used in AirDots are better at storing charge and are more stable when recharging regularly. If you don't plan to use the headphones for a long time, leave them charged by 50-60%.
