Modern wireless headsets like Xiaomi Mi True Wireless Earbuds Basic offer users a high level of comfort and autonomy, but the process of their initial setup is often questionable. Many owners face a situation where only one earbud is activated after extraction from the case, and the second remains in sleep mode or does not see the smartphone. This is not a sign of a malfunction of the device, but rather a feature of the TWS (True Wireless Stereo) protocol, which requires proper channel synchronization.
To make full use of stereo, you need to perform a series of sequential actions that will ensure a stable connection between the left and right modules. It is important to understand that the Bluetooth module in this model works on the principle of "master client", where one headphone takes the role of the master device for data transfer, breaking this balance leads to monophonic sound, which significantly reduces the quality of listening to music or conversations.
In this guide, we will take a detailed look at all the steps needed to pair both speakers correctly with your mobile device. You will learn how to properly initialize your headset, what lights signal readiness to connect, and how to avoid typical errors when you first start. Careful adherence to the algorithm will allow you to enjoy surround sound without delays and connection breaks.
Preparing the headset for the first use
Before you try to find the device in the smartphone menu, you need to make sure that both headphones have sufficient battery power. Often the reason for the failure of one of the modules to work is a deep discharge that blocks the Bluetooth function. Place both headphones in the charging case and connect it to the power source for 15-20 minutes, even if the indicators indicate the presence of power.
Make sure the contacts on the headphones themselves and inside the case are clean and have no oxidation or protective film.Manufacturers often stick microscopic insulators on charging pins that must be removed before first use. If the contacts are contaminated, wipe them with a dry soft cloth or cotton swab dipped in isopropyl alcohol.
💡
If the headphone indicators do not light up when placed in the case, slightly press them or move them to ensure close contact with the charging pins inside the case.
After checking the charge, remove both earbuds at the same time, at which point they should automatically go into pairing mode, as indicated by the flashing of the indicators. If you take them out in turn, the second earbud may not activate, as the communication protocol waits for simultaneous start for synchronization of channels.
The process of synchronizing the left and right earphone
The key step is to start pairing with each other before the device appears on the list available on the phone. Take both headphones in your hands and press the touch panels (or mechanical buttons, depending on the modification) simultaneously and hold them for about 5-7 seconds.
When you see a quick blink on both devices, it means they've gone into search mode for each other. Put them next to each other on the table, but don't put them in the case. In a few seconds, one of the indicators should go out or start flashing slowly (once every few seconds), while the other will blink quickly or slow down too, signaling that the stereo is formed.
☑️ Verification of synchronization TWS
Now you can switch to a smartphone connection. Open the Bluetooth settings on your device and start a search. The list should show one device called Xiaomi Mi True Wireless EBs Basic (or similar). If you see two identical names, then the sync between the headphones did not go well, and the procedure should be repeated.
Bluetooth settings on a smartphone and tablet
Once you've successfully formed a stereo pair, find your headset on the list of available devices. Click on the name to connect. The system can request a pairing confirmation -- agree with it. At that point, you'll hear a "Connected" voice notification on both headphones, which confirms that the audio stream is successful.
Importantly, all functions, including voice assistant management and charge display, may require Mi Wear or Xiaomi Earbuds. Download it from your smartphone’s official app store. This software can check the headphone firmware version and update it if needed, often solving connection stability issues.
Why do you need a management app?
If only one headphone is displayed in the list of devices, try to delete (forget) all previous entries about your Xiaomi headphones in the phone's Bluetooth menu. Cleaning up the cache of old connections often helps the system re-identify the stereo device correctly and assign the correct usage profile.
Resetting settings to factory parameters
In cases where the standard procedure does not help and the headphones refuse to work in pairs, you need to perform a full reset (Hard Reset).This operation returns the device to its original state, removing all saved pairing profiles and eliminating software errors. To perform the reset, place both earphones in the charging case.
Without closing the case cover, press and hold the touch zones on both headphones simultaneously during the course of the day. 20-30 The lights will flash several times, then go out and light up again in red, and only after the red light comes out, release the panels.
⚠️ Warning: Do not remove the headphones from the case during reset or disconnect the case from charging if the battery level is low.
Once reset, you need to re-do the initial pairing procedure described in the previous sections: Remove the device from the Bluetooth list on the phone and find it again, and 90% of the time, this method solves the problem of channel desynchronization.
Diagnostics of typical connection problems
Even after successful connectivity, users may experience periodic communication interruptions or only one channel. Often 2.4 GHz radio interference. Wi-Fi routers, microwave ovens, and other wireless devices can create interference that disrupts the stability of Bluetooth connections.
It’s also worth checking your smartphone’s power settings. Some Android shells aggressively save battery power by forcibly turning off the background processes of the Bluetooth headset. Add the app you’re listening to music through and the Bluetooth system service to the exception list or “do not optimize.”
| Problem. | Possible cause | Decision |
|---|---|---|
| Only one headphone works. | TWS synchronization error | Perform reset and reconnect |
| Low volume. | Different levels of volume of devices | Turn the volume on max. on the phone and headphones |
| Frequent cliffs of sound | Interference or low charge | Charge the case, move away from the Wi-Fi router |
| One earphone doesn't charge. | Contact contamination | Wipe the contacts with alcohol, press in the case |
Operation and care recommendations
To extend the life of your Xiaomi Mi True Wireless Basic and prevent connection problems in the future, follow simple operating rules.Rub the speaker grid and charging contacts regularly, as earwax and dust are dielectrics and can block sensors and charging.
Try to keep batteries from running out of power for a long time. Lithium-ion batteries degrade faster if they are in zero charge for a long time. If you don't plan to use headphones for a few weeks, charge them to at least 50-60%.
⚠️ Warning: Do not use headphones in extremely low or high temperatures. Overheating or hypothermia can temporarily disrupt the battery and radio module, which will lead to a failure of the connection.
Keep the headset in a dry place, preferably in the original case with the lid closed, which protects the electronics from moisture and dust, which are the main enemies of miniature acoustics, and if these conditions are met, the device will please you with quality sound for many years.
