Buying new wireless headphones is often marred by an unexpected problem: instead of working as a unit, the left and right modules stop syncing with each other. This is a common situation for owners of Xiaomi Mi True Wireless, when one channel sounds, and the second is silent or plays back the sound with a delay. The user is faced with confusion, not understanding why the device just removed from the box behaves incorrectly.
Reconnecting modules is a simple process, but it requires a strict sequence of actions. Most often, the problem is to desynchronize Bluetooth protocols or residual charges in capacitors that prevent the system from starting properly. You don't have to carry the gadget to the service center, because 99% of the time it is solved by software resetting at home.
In this article, we will take a closer look at the connectivity recovery algorithms for the Mi True Wireless series, including the Earbuds Basic, Redmi Airdots and newer versions. You will learn about the intricacies of factory reset, how to pair with different operating systems and how to prevent future out-of-synchronizations. Be prepared to have your headphones again enjoy quality stereo sound.
Why the headphones stop working in pairs
Before you start active recovery, you need to understand the nature of the problem. Xiaomi wireless headphones use its own synchronization protocol, which can be broken when one of the modules is below the critical level. If you have not used the device for a long time or one earphone has died faster than another, the system could lose the “master device” that is responsible for transmitting sound to the “slave”.
Another common cause is software conflicts in the memory of a smartphone's Bluetooth module.The phone may try to connect to both headphones as independent devices, ignoring their internal communication.This often happens after a phone operating system update or a smartphone change. Signal interference from other wireless devices can also affect connection stability.
⚠️ Warning: If one of the headphones is completely discharged, the synchronization procedure will not begin.Make sure both modules are charged before trying to pair them.
Sometimes the problem is that the charging contacts inside the case are contaminated, and if the earphone is not fully charged due to dust or oxidation, it can shut down during operation, breaking the connection with the paired device, and regular cleaning of the contact areas with a dry cotton swab helps to avoid similar situations in the future.
Preparation for reconnection
The effectiveness of the reset procedure depends on proper preparation. The first step is to completely forget the device in your smartphone settings. Go to the Bluetooth menu, find the Mi True Wireless EBs Basic (or your model) list, and press the disconnect or delete button, a critical step that is often ignored.
Once removed from the phone list, you need to turn off Bluetooth on the smartphone itself, which will prevent automatic attempts to reconnect during setup, which can disrupt the synchronization process between the left and right earphones. While the phone is looking for the device, the headphones will not be able to find each other to create a pair.
- 📱 Remove the device from the list of saved in the Bluetooth menu of the phone.
- 📶 Turn off the Bluetooth module on your smartphone or tablet.
- 🔋 Place both headphones in the charging case on 5-10 charge-alignment.
- 🧼 Wipe the contacts on the headphones and inside the case with dry cloth.
It's also important to check that the charging case itself has sufficient energy, so if the indicators on the case don't light up when you put the headphones inside, maybe the case is discharged, so you can charge it, otherwise the reset procedure may be interrupted halfway.

Methods of resetting Xiaomi headphones to factory settings
There are several ways to reset, and the choice of the specific method depends on modifying your headset. For most models of the Redmi Airdots and Mi True Wireless Basic series, the method using touch panels is relevant. You need to remove the headphones from the case and make sure that they are turned off (the indicators do not burn). If they are on, press the touch areas on both headphones simultaneously for 5-7 seconds before turning off.
Once turned off, double tap. Press and hold the touchpads on both headphones for 15-20 seconds. The indicators will flash red several times, then light up white, and then flash red again. It is at the second flash in red (or after a series of blinks) that the buttons are released. This is a signal that the reset was successful.
⚠️ Warning: Do not release the buttons immediately after the first light of the indicators. Waiting for a series of blinks, you are guaranteed to start the reset mode, not just the pairing mode.
Newer models, such as the Mi True Wireless Earbuds Basic 2 or Pro version, may require the use of a button on the case itself. If there is a physical button on the case, put the headphones inside, close the lid and press the button for 10 seconds before changing the color of the indicator. This is a versatile method that often works more than touch control.

Synchronization of the left and right channel
Once the reset is successfully performed, the earbuds go into standby mode, and the most important process is to find each other, remove both earbuds from the case at the same time. Don't touch them during the reset. 10-15 And then you have a second, and you give them time to automatically sync with each other, and then you have the lights flashing white very quickly.
If it goes right, one of the indicators (usually the right earbud) will go out or start flashing slowly, and the second (left) will continue to blink quickly, which means that the right channel has become a master device and is now waiting for the smartphone to connect, and the left is already connected to the right, and the sync is complete, and now you need to connect them to the phone.
Turn on Bluetooth on your smartphone and start looking for devices. The list should show one device with the name of your model, for example, Mi True Wireless EBs. Basic_R. If you see two identical names or names with prefixes L and R, then the synchronization between the headphones did not occur, and the reset procedure must be repeated.
| Indicator | Meaning | Action. |
|---|---|---|
| Fast blinking (both) | Smartphone search mode | Wait or search in Bluetooth |
| Slow blinking (one) | Connection waiting mode | Put it on the phone. |
| It's burning all the time. | Headphone connected | We can use it. |
| Blinks red. | Low charge or error | Put it on charge. |
💡
If the lights are different colors or flashing in different colors, put the headphones back in the case, close the lid and wait 10 seconds before trying again.
Connection with Android and iOS devices
The process of connecting to Android and iOS smartphones has its own peculiarities, although the basic algorithm is the same. On Android devices (Xiaomi, Samsung, Huawei), after detecting the device, a pop-up with an animation of charging the case and headphones can appear. This is a proprietary MIUI feature that displays the charge level of each module separately.
For iPhone and iPad owners, the process looks standard: the device is listed as “Other Devices.” Once you click on the name, you may need to confirm pairing. It’s important to note that iOS sometimes caches older device profiles more aggressively, so if the connection fails, try rebooting the smartphone itself before re-searching.
In rare cases, manual input is required. PIN-The standard code for Xiaomi headphones is usually 0000 or 1234. If the phone requests the code and you didn't type it, try one of these combinations. Once successfully connected, it's recommended that you check the channel balance in the special features settings to make sure the sound is evenly distributed.
Troubleshooting and frequent errors
Even after the correct reset, there can be situational problems. If only one earphone has sound, check the balance mixer settings in the phone. Sometimes a software failure shifts the balance completely to one side, creating the illusion of a second channel breakdown, and it is also worth checking whether Mono-audio is activated in the special features settings.
If the headphones are permanently turned off, perhaps the distance between them and the phone is too great, or the signal is blocked by the user's body. Bluetooth has a limited range, and a pocket of pants with a phone can shield the signal if you hold the phone in the back bag. Try putting the smartphone in your chest pocket for inspection.
- 🔊 Check the sound balance in the phone settings.
- 📡 Make sure there are no strong sources of interference (Wi-Fi routers, microwaves).
- 🔄 Reboot your smartphone to clean up your Bluetooth cache.
- 🔋 Charge the case and headphones to 100%.
⚠️ Warning: If after all the manipulations, one earphone is still silent, try connecting the headphones to another phone. This will help you understand whether the problem lies in the smartphone or in the headphones themselves.
💡
If the problem persists on different devices after a complete reset, a hardware malfunction of the battery or Bluetooth module in a quiet earphone is likely.
