Today’s users often face a situation where two devices need to be combined into a single audio system. Xiaomi ecosystem owners may want to create a stereo pair of two mono-blocks or connect new ones. TWS-The synchronization process depends on the specific model and type of device, whether it is the classic Mi True Wireless or the overhead versions of the Mi Headphones series.
Understanding how Bluetooth works helps avoid mistakes when you first start a gadget. Many users mistakenly believe that headphones require complex manual adjustments through hidden developer menus. In fact, modern MIUI algorithms and proprietary Earbuds software take most of the work on themselves, providing instant detection of devices.
In this article, we'll look at all the nuances of pairing, from standard procedure to connection conflict resolution, how to activate the pairing mode correctly and what to do if one of the headphones stops hearing the other, and it's important to consider that different generations of devices may have different logics of the indicators.
Principles of work of TWS-headphones Xiaomi
True Wireless Stereo technology means that there are no physical wires between the sound source and the headphones, but also between the earbuds themselves. The left-right channel is radio-linked, usually in the 2.4 GHz band. When switched on, the devices must find each other to then broadcast the sound synchronously, without delay and dissynchronization.
The key element here is the master device. In most Xiaomi models, one headphone (often the right one) acts as the host, taking the signal from the smartphone and transmitting it to the guided earpiece. If this connection is broken, the user hears sound in only one ear or observes constant breaks in the connection.
The initial synchronization process often happens automatically inside the charging case, and when you remove both headphones at the same time, they exchange service packets of data. If you take them one at a time, the system may perceive this as mono-mode, so it is important to follow the sequence described in the instructions for a particular model, for example, Redmi Buds 3 Pro or Mi True Wireless Earphones 2.
⚠️ Warning: Do not force your headphones to be connected via the Bluetooth menu of your smartphone as two separate devices, which will lead to channel conflict and stereo sound inability.
Modern chips like the Qualcomm QCC or Realtek used in Xiaomi flagships support low latency. However, activating all features, including ANC (active noise cancellation) and transparent mode, requires a successful connection to the smartphone through a special application. Without this step, the headphones will only work as a regular Bluetooth headset at the base level.
Preparing devices for the first connection
Before you start the pairing procedure, you need to make sure that both devices are ready to go. The first step should always be to check the level of charge. A discharged battery in the case or the headphones themselves may not give enough voltage for the powerful Bluetooth signal needed to find a pair. Put both modules in the case and connect it to charge for at least 15-20 minutes.
The second important step is to clear the list of paired devices. If your headphones have previously connected to other gadgets, they may try to automatically connect to the latest known device, ignoring your current phone. Go to Bluetooth settings on older devices and select Forget the device or Disable for your Mi Earbuds.
- 🔋 Make sure the charge of the case is more than 30% for stable operation.
- 📱 Turn off Bluetooth on all other devices within a 10-meter radius.
- 🧹 Wipe the contact areas on the headphones and inside the case with dry cloth.
- 🔄 Reboot your smartphone to update the Bluetooth stack with the system’s operating system.
You should pay special attention to the contacts, and they often get earwax or oxides, which prevents the headphones from knowing that they are in the case. If the system does not see that the headphones are in the case, they will not go into pairing mode. Use a cotton swab, slightly moistened in alcohol, to clean the gold contacts carefully.
Step-by-step: standard pairing
The process of connecting most Xiaomi and Redmi models is unified for user convenience. Once you have prepared the devices, open the charge case cover without removing the headphones themselves. The display should light up on the front or back of the case (depending on the model). If the indicator flashes white, the device is ready to search.
If you don't automatically go into pairing mode, you need to use a function button, which can be located on the end of the case or between the headphones inside. Press and hold this button for 2-3 seconds until the indicator flashes often. This is a signal that visibility mode is activated.
☑️ Preparedness
Now, take your smartphone and go to the settings menu. The path usually looks like: Settings → Bluetooth. The list of available devices should show the name of your model, for example, Mi True Wireless Earphones 2 Basic. Click on it to complete the connection. Successful will be confirmed by a voice message "Connected" or a characteristic beep.
MIUI-based smartphone owners are the luckiest. When you open a case next to an unlocked Xiaomi phone, an animated window with the charge level of each headphone and case appears on the screen. This is a proprietary MIUI Pop-up feature that works faster than a standard Bluetooth search. Just click "Plug" on the pop-up.
⚠️ Warning: During pairing, keep the case with headphones at a distance of no more than 50 cm from the smartphone. Exceeding the distance may interrupt the exchange of encryption keys.
Setup a stereo pair of two mono-earphones
Some users buy two separate mono headphones (such as Mi Sports Bluetooth Earbuds or older Redmi models) wanting to use them as a stereo headset. TWS-You have to force both devices into search mode and connect them together before you connect to the phone.
Turn on both headphones first. This is usually done by pressing the control button long or holding the touch zone. Wait for the lights to flash alternately in red and blue. This means that the devices are looking for each other, at which point they can find a partner on their own, as reported by a rare flash of the indicator (usually blue once every few seconds).
| Model | Search indication | Indication of a pair | Reset |
|---|---|---|---|
| Mi True Wireless 2 | White flashing | Persistent light | 20 seconds in the case |
| Redmi Buds 3 | Orange light | Blue light | The button on the case |
| Mi Sport Youth | Red and blue. | Blue rare. | Long press. |
| AirDots | Double blinking. | Single | 5 seconds off. |
Once the headphones have found each other (become a pair), turn on Bluetooth on your smartphone and find the device in the list. Now the phone will see only one device, and the sound will be distributed to both channels. If the phone sees two identical names, then the stereo is not created, and the procedure must be repeated, previously removing the device from the memory of the phone.
