Modern users often face a situation where one of the wireless headphones loses charge, breaks or simply loses. Owners of the Xiaomi ecosystem are in a great position, as the company has provided the possibility of combining two separate devices into a single stereo system, which allows not only to replace the lost “ear”, but also to create a full-fledged device. TWS-True Wireless Stereo is a two-headset, combining the process with a mindfulness to detail, but the result is worth it.
Technically, the procedure is a forced pairing of left and right channels before connecting to a smartphone. Bluetooth protocol of modern gadgets allows you to synchronize audio streams with minimal delay. However, if you miss even one step in the sequence of actions, the devices may not see each other or operate in the mode of independent mono-earphones.
In this article, we will not only look at the standard method of connection, but also look at possible problems with desynchronization of sound. You will learn how to properly reset the settings of headsets and which models of Redmi and Mi support this feature out of the box.
Preparing headphones for unification
Before starting the procedure, make sure that both devices are ready to go, the first step is to completely discharge the batteries of both headphones to a state of complete shutdown, this is necessary in order to reset the current cached connections in the memory of Bluetooth modules, leave the gadgets outside the charging case for a few hours or until the indication is completely stopped.
Once the devices are guaranteed to be turned off, put them in a charging case. Make sure the contacts are clean and not oxidized, as poor contact can lead to uneven charge. Leave them in the case for at least 30 minutes to gain at least 50% of the battery capacity. Fully charged devices work more stable during primary pairing.
⚠️ Note: Do not try to combine headphones if one of them is charged less than 20%. During the synchronization, the Bluetooth module is in a high mode, and the discharge may interrupt the procedure, which will lead to a software failure.
The next important step is to clean up the list of paired devices on your smartphone. Go to Bluetooth settings and delete all the old entries about your Xiaomi or Redmi headphones. This will eliminate the conflict of addresses and allow gadgets to have a new connection from scratch. If the phone remains an old profile, the headphones can try to connect to it in mono mode, ignoring each other.
💡
Before starting the procedure, be sure to turn off Bluetooth on all other devices within a 10-meter radius to avoid automatic interception of the connection by a tablet or laptop.
Step-by-step instructions for synchronization of TWS
The basic method of connecting requires precise timing of actions. Remove both earbuds from the charging case at the same time. At this point, they should start flashing indicators, signaling the search mode. If one of them catches fire and the other does not, return them to the case and try again. Synchrony of extraction is a critical factor in success.
Now you need to initiate pairing between the headphones themselves. Most AirDots and Redmi Buds models require you to quickly press 5 times on the touchpads of both devices. Other models, such as Mi True Wireless Earbuds Basic, need to hold the sensors for 5-7 seconds before changing the color of the indicator. The specific combination depends on the firmware version of the device.
- 🔹 Remove both headphones from the case at the same time and wait for the flashing of indicators.
- 🔹 Press and hold the touch panels on both devices during the 5-7 seconds.
- 🔹 Wait until one earbud stops blinking and the second continues to blink slowly.
- 🔹 In the Bluetooth menu of the smartphone, find the device and connect.
The successful outcome is when one headphone goes out or flashes rarely (standby mode), and the other continues to actively search for the device, which means that the left and right channels have connected and now represent a single stereo pair for the phone, and if both continue to blink quickly, then they have not seen each other and work independently.
☑️ Synchronization checklist
Features of connecting different models
Xiaomi’s ecosystem includes many models, and the algorithm for their operation may differ. For example, the Mi True Wireless Earphones 2 series often supports automatic pairing when opening a case if the devices have previously been paired. At the same time, Redmi AirDots budget models require manual synchronization through multiple touches on sensors.
For active noise cancellation (ANC) models, the process can be complicated by the presence of additional software, sometimes requiring the use of a proprietary Mi Home or Xiaomi Earbuds app to initially configure and update the firmware before combining. Without current firmware, communication modules may not work properly.
Below is a table of compatibility and methods for popular series:
| Model headphones | Resetting method | Success indicator | Annex |
|---|---|---|---|
| Redmi AirDots | 5 quick presses | Red indicator | Not required |
| Mi True Wireless 2 | 10 seconds retention | White flashing | Mi Home |
| Xiaomi Buds 3 | Through the app | Sound signal | Xiaomi Earbuds |
| Haylou GT1 | 4 taps | Red-blue flashing | Not required |
Pro owners should pay attention to the Bluetooth version. If one earphone has a module 5.0 and the second 5.2 (for example, when replacing one ear with a newer revision), they may not connect due to differences in data protocols, in which case combining different generations of the same model is often impossible without flashing.
Solving problems with desynchronization
A common problem is when the headphones are connected, but the sound is only coming from one, or the channels are confused (on the left you can hear what should be on the right), this is called desynchronization of the stereo channels. To solve the problem, you need to perform a full reset. Find hidden buttons on the body of small headphones or use sensors to enter reset mode, usually 10-20 seconds of retention.
If the software reset doesn't work, try the operating system-level "forget" method of the device: delete the headphone profile in Bluetooth, turn off the phone, remove the headphones from the case, pinch their sensors before turning them off, and then turn the phone back on. This sequence of actions helps to clean up DNS-Bluetooth cache on your smartphone.
⚠️ Note: When you complete a full reset, all saved equalizer settings and button assignments will be deleted. You will have to reset them through the app or manually.
In some cases, the problem is not the headphones, but the Bluetooth codec used by the phone. If you use high-resolution codecs like LDAC or aptX HD, try temporarily switching to standard SBC in the Android developer settings, which will help diagnose whether the problem is hardware or software.
Use of Mi Home and Xiaomi Earbuds
Advanced setup and integration of ecosystem devices often requires proprietary software. Xiaomi Earbuds app (formerly known as Mi True Wireless) allows you not only to update the firmware, but also to force the search for a second headphone.
The app often has a hidden delay calibration feature, which is critical for gamers. If you notice audio and video in-game synchronizations after combining two headphones, use the built-in Game Mode tool, which optimizes the priority of data packets for left and right channels.
What to do if the app does not see the headphones?
Remember, the app also shows the exact percentage of charge of each headphone separately.This helps to identify the "weak link" - a device that holds the charge worse and can shut down earlier, breaking the stereo pair. Regular updates through the app fixes connection bugs.
Frequent errors when connecting
One of the most common mistakes is trying to plug headphones while they're in the case.Some Xiaomi models go into pairing mode just outside the charger.Make sure the indicators are on before looking for the device in the phone's menu.
Another mistake is to ignore the distance: when two headphones are first paired, they must be close to each other (literally touching). If held in different hands at a distance of 20 cm, the signal may be too weak to establish master-slave communication.
- 🔹 Trying to connect without first removing your old Bluetooth profile.
- 🔹 Finding headphones far from each other at the time of synchronization.
- 🔹 Use of discharged batteries, which leads to a break in the communication process.
- 🔹 Ignoring the need to update the firmware through the application.
Also, users often confuse mono and stereo, so if you have two devices with the same name on your phone (like "Mi True Wireless EB" and "Mi True Wireless EB"), it's a mistake. There must be one device. If there are two, then they're not paired.
💡
The main secret of success is a complete cleanup of Bluetooth history on the phone and the simultaneous removal of headphones from the case to start the procedure.
