Owners of modern wireless headsets often face the need to restore communication between the right and left ear inserts. The situation when only one earpiece is working and the second one is silent is one of the most common problems in the world. TWS-This can happen after a battery drain, a smartphone operating system update, or a simple software failure in the data protocol.
The process of reconnecting communication channels depends on the specific model of your device, whether it is the popular Xiaomi Redmi Buds, Mi True Wireless Earphones or more advanced Xiaomi Buds 3 Pro. In most cases, the problem is solved by simply restarting or resetting to factory settings, but there are nuances that not all users know about.
In this article, we will go into detail the algorithms for different scenarios so that you can enjoy full stereo sound again. It is critical to reset both headphones simultaneously in a case so that they rediscover each other and create a single network. Follow the instructions carefully to avoid synchronization errors.
Reasons for the desynchronization of wireless headphones
Before you start actively reconnecting, you need to understand the nature of the malfunction. Often users blame the hardware failure, although 90% of the time it's a software conflict. When you take the headphones out of the case, they have to automatically connect to each other, and then to the phone. If that order is broken, you get out of sync.
One of the main reasons is the different charge levels in the left and right ear inserts, and if one of them is zero and the other is still charged, they may not be able to sync their internal clock before the next charge, and they may also have problems switching between devices, such as when you listen to music on a tablet and then try to connect quickly to your smartphone.
External factors such as radio interference or the presence of old connection profiles in Bluetooth memory affect connection stability. The accumulation of a pairing cache can cause the device to try to connect to the “old” destination, negating the second channel. Understanding these causes helps to diagnose the problem faster.
- 📉 Different battery levels in the left and right modules, leading to asynchronous switching on.
- 🔄 Bluetooth profile conflict with frequent switching between different gadgets.
- 📡 Radio interference or congestion at the place of use of the device.
- 🛑 Software firmware failure after updating or incorrect disconnection.
⚠️ Note: If one of the headphones has been in a discharged state for a long time, it may need from 15 to 30 minutes of charging in a closed case before starting the recovery procedure.
Preparation for reconnection
The effectiveness of the connection procedure depends on the quality of the pre-preparedness. You should not try to pair devices on the go or in poor communication conditions. First, you need to clear the connection history on your mobile device. Go to the Bluetooth settings, find your model in the list, for example, Xiaomi Mi True Wireless Earbuds Basic 2, and select the option “Forget device” or “Delete”.
When you delete your profile, make sure you turn off the Bluetooth module on your smartphone, and this action will forcefully break all the background search and waiting processes that can interfere with the new clean connection, and while the phone is silent, we will take care of the headphones themselves.
Make sure both earbuds fit tightly to the contacts in the charging case. Indicators should burn or flash to signal the charging process. Dirt on the contacts or moisture can prevent the normal start of the reset procedure. Wipe the contacts with dry cloth if you notice oxidation.
☑️ Preparation for reconnection
Connection method through resetting (Hard Reset)
The most effective way to get the headphones back to work in pairs is to completely reset to factory settings, a method that is relevant for most models of the Redmi and Mi lineup. The algorithm of actions can vary slightly depending on the presence of a physical button on the case or touch zones on the liners themselves.
If your charger case has a control button (usually on the back wall or inside between compartments), the process is simplified. Place both earphones in the case and leave the lid open. Press the reset button and hold it for 10-15 seconds. The status indicator should start flashing white or orange, which signals the transition to pairing mode.
For models without an external button, such as the basic versions of the Xiaomi Earbuds Basic, touch control is used. You will need to simultaneously touch the touch areas on both headphones while they are in the case (or one by one, depending on the instructions of the particular model), and hold your finger for about 5-7 seconds. In some cases, you need to press 5 times quickly in a row.
What to do if the indicator does not flash?
After a successful reset, the indicators should flash to indicate readiness for (mating), now you can turn on Bluetooth on your phone and start searching, and the name of your gadget will appear in the list of devices.
- 🔘 Models with button: hold 10-15 second-on.
- 👆 Models without a button: 5 quick touches of touch zones or long-term retention.
- 💡 Indication: white flashing – search mode, orange – error or charging.
- 📱 Confirmation: Appearance of the device name in the Bluetooth list on the smartphone.
Using the Xiaomi Earbuds app to customize
For owners of Android smartphones, especially devices branded Xiaomi, POCO and Redmi, it is highly recommended to use the specialized application Xiaomi Earbuds (or Mi Wear for older models), this software tool allows not only to connect the device, but also deeply customize its operation, which is impossible to do through the standard Bluetooth menu.
After initial pairing through system settings, open the app. It automatically detects the connected headphones and prompts them to update their firmware. Often, it is the software update that eliminates desynchronization bugs that cannot be fixed by mechanical reset. Developers regularly release patches that improve the stability of the connection.
In the app interface, you can check the charge of each headphone individually, which helps to identify the “weak link” in the pair, and you can also adjust gestures, equalizer and low latency mode (Game Mode). For some models, such as Xiaomi Buds 3, the application allows you to reassign the functions of the touch zones, adapting the control to your habits.
⚠️ Attention: Updating the firmware through the application requires a stable Internet connection and a case charge of at least 50%. Do not open the case cover during the update, so as not to interrupt the data recording process.
Comparative table of discharge models and methods
Different generations of devices can have unique combinations of actions, and to make it easier for you to navigate, we have prepared a summary table for popular models. Note that for some devices, the method may vary depending on the regional version.
| Model headphones | Type of management | Action for discharge | Indication of success |
|---|---|---|---|
| Redmi Buds 3 / 3 Pro | Sensor + Case Button | Hold the case button 10 seconds | Orange blinking |
| Mi True Wireless Earbuds Basic 2 | Touch (touch) | 5 quick touches of both headphones | Double blinking. |
| Xiaomi Buds 3T Pro | Sensor + Annex | Through the Mi Wear app or 10 seconds in a case | White flashing |
| AirDots / Redmi AirDots | Touch (touch) | Hold 20 seconds (one at a time) or 5 times | Red/white flashing |
If your model isn't in the table, try the universal method: place the headphones in the case, close the lid, wait 10 seconds, open and simultaneously touch the sensors on both headphones for 5-10 seconds. This technique often works on cross-platform devices.
💡
For a precise model definition, look at the bottom of the charging case – there is a small print of the full model code (for example, TWSEJ06LS), which is easy to find the official instructions.
Solving problems with sound desynchronization
There are situations where the headphones are connected, but the sound is only coming from one, or there is a de-synchronization of audio and video. This may indicate that the devices are operating in mono mode or lost communication with each other while remaining connected to the phone. In such cases, repeat the reset procedure, but with the Bluetooth on the phone turned off.
Another reason could be that the activated Mono-audio mode in Android or iOS special features, check your smartphone's availability settings. If this mode is on, the phone will only send a signal to one device, considering it to be the main one, and turn off this feature to make the stereo pair work properly.
It's also worth checking the sound balance. The device's audio settings have a left-right channel balance slider. Make sure it's set in the middle. The one-way shift is often perceived by the user as a break in the second headphone.
- 🎚️ Check the channel balance in the smartphone sound settings.
- 🔇 Turn off the Mono-Audio mode in the Special Opportunities section».
- 📵 Turn off Bluetooth on all other devices within a 10-meter radius.
- 🔄 Complete the full reset again, strictly following the timing.
💡
If after all the manipulations, the sound is only in one headphone, try connecting the headset to another smartphone, which will help you understand whether the problem lies in the earphone itself or in the settings of your phone.
