Owners of modern electronics often face a situation where wireless devices are used. TWS-The headphones stop working in pairs, and one channel may be silent, the sound may be distorted, or the devices may not find each other after being removed from the case, a common problem that is solved by the correct re-synchronization procedure. In this article, we will discuss in detail how to return your Mi True Wireless Earbuds or Redmi Buds factory setup between channels.
The process of restoring communication depends on the specific model and version of the firmware, but the basic algorithm of actions remains similar for most devices of the brand. It is critical to understand that standard pairing via Bluetooth in the phone does not always solve the problem of desynchronization of the left and right channel. Often it requires a forced reset of the headphones themselves so that they shake hands with each other again. We will look at both software methods through the application and hardware reset methods.
Before you start complex manipulations, make sure your devices are charged. Low battery power is often the cause of unstable Bluetooth module. If you notice that one earphone discharges faster than another, this may be the first sign of desynchronization. Let's take a look at the basic stages of preparation and setting.
⚠️ Warning: Before starting the reset procedure, be sure to remove (forget) the Bluetooth device on your smartphone.This will prevent address conflicts when reconnecting.
Preparing for synchronization and cleaning Bluetooth memory
The first and most important step is to completely clean up your connection history. A smartphone can try to connect to an old device profile, ignoring the new settings we're going to apply. You need to go to Settings → Bluetooth and find your headphones on your device list.
Click on the gear icon or information icon next to the model name. In the menu that opens, select the option “Unpair” or “Forget the device.” After that, it is recommended to turn off Bluetooth completely on the phone for 10-15 seconds, and then turn it on again. This action will reset the cache of the Bluetooth stack of the operating system.
It's also worth checking for updates to Google Play's system services, as they're responsible for many communication protocols. If you have third-party audio management apps other than the official ones installed, it's also best to temporarily disable them.
☑️ Preparation of the device
Hardware reset via touch panels (TWS models)
Most modern models, such as the Mi True Wireless Earphones 2 or Redmi AirDots, don't have physical buttons on the body. Control and reset are done through touch zones. To perform the reset, place both earphones in the charging case, but don't close the lid. Indicators should burn, signaling the charging process.
Press both headphones simultaneously and hold your finger for 20-30 seconds. The indicators will flash red several times before they go out or light up white. The exact retention time can vary: 5 seconds is enough for some Xiaomi models, and up to 30 seconds for others.
Once the lights flash, remove the headphones from the case, and they should automatically go into pairing mode (usually indicated by the quick blinking of a white or blue light), now you can search for them in the Bluetooth list on your phone as a new device.
- 🔴 The indicator flashes red - there is a process of resetting or discharge.
- ⚪ The indicator flashes white / blue - pairing mode (Pairing Mode).
- 🟢 The indicator is constantly on – the device is connected and works.
⚠️ Warning: Do not remove the headphones from the case while holding the touch panels. This will interrupt the reset process and may lead to improper operation of the firmware.
What to do if the sensor is not responding?
Resetting headphones with a physical button on the case
Flagship models such as the Mi True Wireless Earphones 2 Pro or Xiaomi Buds 3 Pro often feature a feature button on the back or side of the charging case, which is the most reliable method of synchronization, as it eliminates human factor and inaccuracy of timings when pressing on sensors.
Place both earbuds inside the charge case. Make sure they fit tightly to the contacts and the lights on them are on. Close the case cover. Find a round button on the case and press it. Depending on the model, the pressing can be short-term (1-2 seconds) or long-term (10-15 seconds).
Usually, when a successful reset occurs, the indicator on the front of the case flashes white quickly, and it signals that the headphones have entered global pairing mode and are ready to find a new host, and if the indicator flashes orange, then the charge of the case or headphones is critically low.
Importantly, in some models, pressing a button on a closed case is responsible for entering pairing mode, and in the open case, for resetting. Watch the color of the indicator carefully. White fast flashing is the universal signal of readiness for connection for all devices in the Mijia ecosystem.
💡
Use a cotton swab dipped in alcohol to wipe the contacts inside the case before the procedure. Oxidation of the contacts can prevent the headphones from knowing that they are in the case, which blocks the reset function.
Use of Mi Home and Xiaomi Earbuds
For deep customization and synchronization of the equalizer, it is recommended to use official applications. Global versions of devices most often require the Xiaomi Earbuds app (or Mi Buds), and for devices sold in China, or for full integration into the smart home, the Mi Home app.
Once you connect your headphones to your phone via Bluetooth, open the app. It automatically detects the connected ones. TWS-Headphones. In the device menu, look for the Settings or Systems section, and it may have a button called Reset your headphones or Unpair, and software reset is preferable because it ensures that the internal address table is updated correctly.
The app also has a firmware update feature. Often the problem with desynchronization lies in software bugs, which are fixed in new versions of the software. If your headphones are unstable, check the "About Headphones" tab and click "Check Updates".
| Model headphones | Annex | Resetting method | Indication |
|---|---|---|---|
| Redmi AirDots | Mi Buds / Mi Home | Sensor retention 20 seconds | 5 flashes red |
| Mi True 2 | Xiaomi Earbuds | Sensor retention 10 seconds | Blinking white |
| Buds 3 Pro | Xiaomi Earbuds | Case button 10 seconds. | Orange → White |
| FlipBuds Pro | Xiaomi Earbuds | The button on the case | White flashing |
Synchronization with devices of different ecosystems
Xiaomi headphones work great not only with Android, but also with iOS, as well as with Windows PC. However, the process of initial synchronization can be nuanced. On iPhone, Mi True Wireless devices do not support the pop-up with charge animation that is available on Xiaomi smartphones. You will have to connect them through the standard Bluetooth menu.
When connecting to a Windows 10 or 11 computer, make sure that the Bluetooth drivers are up to date. Sometimes the system sees the headphones as Headphone (for calls) and Stereo (for music) at the same time. If the sound is only coming through one channel, check the sound settings in the control panel: make sure that the default playback device is Stereo, not Hands-Free AG Audio.
It is important for iOS users to know that the Xiaomi Earbuds app is available in the App Store, but the functionality may be limited compared to Android.However, basic synchronization and firmware updates are available. If the headphones are not visible on the iPhone, try resetting the network settings on the smartphone itself, as iOS sometimes caches old encryption keys.
💡
Cross-platform headphones Xiaomi is high, but full functionality (noise reduction, equalizer) is available only when using the official application on Android or iOS.
Solving Common Synchronization Problems
Even after you've done all the steps, you can have a hard time, like the phone sees the headphones but it doesn't connect, or it only connects one channel, or you can try to reboot your smartphone, and in the second case, put the working headphone in the case, and leave the non-functioning headphone outside, then repeat the reset procedure only for the external headphone.
Another common problem is the quiet sound or lack of it in one of the channels after synchronization. This may be due to volume balance. Go to Settings → Sound and Vibration → L/R Balance and make sure that the slider is strictly in the center. Also check the cleanliness of the speaker grid - sulfur can physically block the sound.
If nothing helps, it may be a hardware problem. Check the charging contacts in the case. If one earphone doesn't charge, it won't turn on and sync. Wipe the contacts with alcohol. If that doesn't work, you need maintenance.
- 🔊 Check the balance of left and right channel in the phone settings.
- 🧹 Clean the speaker mesh from earwax and dust.
- 🔋 Make sure both headphones are charged in the case (indicators are on fire).
⚠️ Warning: If after all the reset and reconnection attempts, one earphone is still silent, the Bluetooth module or battery may have failed.
