The situation when Xiaomi or Redmi wireless headphones stop working in pairs is one of the most common problems owners have. TWS-Headset: The user takes both devices out of the case, but sees only one name in the list of available connections, or the sound is played exclusively in one ear, which is puzzling, since True Wireless Stereo technology involves synchronous operation of both modules. Most often, the problem lies not in the physical breakdown of the speakers, but in the software dissynchon between the left and right modules.
When the Bluetooth channel between the headphones is severed, they can't transmit audio to each other, and the smartphone perceives them as two independent mono-device or ignores one of them. In a MIUI or HyperOS system, this can manifest itself in different ways, from the lack of sound in the same channel to the inability to initiate pairing. It's important to understand that in 90% of cases this is a fixable software failure that is solved without going to the service center.
To restore a full stereo pair, you need to perform a series of actions to force the reboot and repair modules. Below we will discuss in detail the algorithms of actions that will help bring your AirDots, Buds or Earbuds back to life. Don’t panic ahead of time – even if the indicators flash chaoticly, the system often remains operational after a proper reset.
The main reasons for dissynchronization TWS-headset
The primary reason for a situation where only one Xiaomi earphone is connected is the desynchronization of communication channels between the left and right modules. In TWS technology, one earpiece (often called a wizard) receives a signal from a smartphone and broadcasts it to a second one (slave). If this internal communication is broken, the data protocol ceases to function correctly, this can occur due to static electricity, a sharp connection break or a software bug in the firmware.
The second major cause is conflicts in the memory of the smartphone’s Bluetooth module. Android sometimes stores erroneous connection profiles when trying to connect to a device that has already changed its status or address. As a result, Xiaomi headphones can get stuck in standby mode without going into an active stereo state.
⚠️ Warning: If one of the headphones is discharged more than the other, the system may block its connection to protect the battery.
A third factor is often the physical contamination of the contact areas in the charging case. If the contacts are oxidized or covered with earwax, the earphone may not receive a signal that it is in the case, and may not reboot when removed, which leads to it remaining asleep or operating in mono-headset mode.
Software reset headphones Xiaomi and Redmi
The most effective way to solve the problem is a full Hard Reset headset. This procedure clears the internal memory of the headphones from temporary files and resets the pairing settings to factory ones. For most Xiaomi models, such as the AirDots 2, Redmi Buds 3 or Mi True Wireless Earbuds Basic, the process looks similar, but has its own nuances depending on the physical button on the case.
If your charger case has a reset button (usually located inside between compartments or on the back wall), the algorithm will be as follows: Place both earphones in the case and leave the lid open. Then press and hold the button for 10-15 seconds until the indicator lights up orange or flashes quickly white.
For models without a physical button (like old AirDots), touch reset is used, so you have to remove both earphones from the case and simultaneously touch touch the touch zones on both devices. 5-7 seconds until they turn off, then repeat the procedure again, holding about 20 seconds before the reset indication appears, then put them back in the case on the 10 seconds.
☑️ Reset algorithm TWS
Once you reset, you need to pair again. Make sure that your smartphone's Bluetooth settings have removed the old device. Only then open the case and look for a new device. It's important to do everything quickly and consistently, as timeouts can interrupt the pairing entry.
Bluetooth settings in Android and MIUI
The problem may lie not only in the headphones themselves, but also in how the MIUI operating system or pure Android handles multimedia profiles. Sometimes the system forgets to assign audio channels correctly, sending sound to only one output. To diagnose, you need to go to advanced Bluetooth settings. In the Settings → Bluetooth menu, find your headphones in the list of paired devices and click on the gear icon next to the name.
Check the active profiles in the menu that opens. Make sure the Media Audio switch is active. If it's turned off, no audio will play. Also, you should pay attention to the option "Dual audio" or "Dual device connection" if you have one in your firmware version. Sometimes turning it off and re-energizing this item helps to restart the audio driver.

Another important aspect is clearing the Bluetooth cache. To do this, go to Settings → Apps → All apps, search for “Bluetooth” (or “Bluetooth MIDI Service”) and select “Clear Data” and “Clear Cache.” This action will not delete your personal files, but reset all current Bluetooth connections, so after rebooting the phone you will have to reconnect your headphones.
| Model headphones | Reset indicator | Retention time | Type of management |
|---|---|---|---|
| Redmi AirDots 2 | Blink 2 times | 15-20 seconds | Touch-sensitive |
| Mi True Wireless 2 | Orange light | 10 seconds. | The button on the case |
| Xiaomi Buds 3 | White flashing | 10 seconds. | The button on the case |
| Haylou GT1 | Red and blue | 5-7 sec (4 times) | Touch-sensitive |
Elimination of hardware conflicts and interference
Sometimes the reason Xiaomi headphones work only one at a time is because of radio interference. Bluetooth protocol runs at 2.4 GHz, which is also used by Wi-Fi routers, microwave ovens and USB 3.0 ports. If you are in a zone of heavy ether noise, the connection between the master and the slack can be unstable. Try to step away from the router or turn off the Wi-Fi on the smartphone while pairing.
It's also worth checking if the smartphone case is blocking the signal. Dense metal or magnetic cases can shield the antenna, which causes the second earphone to simply "lost" and stop receiving the signal. Remove the case and repeat the connection procedure. If the problem disappears, then it was a physical obstacle to radio waves.
⚠️ Warning: Do not store headphones near powerful magnetic field sources (column speakers, transformers) and this can lead to demagnetization of speakers and irreversible reduction of sound quality.
Another factor is energy saving. In some versions of MIUI, aggressive battery settings can kill the Bluetooth service process, leaving only one channel active to save energy. Go to Settings → Battery → Energy Saving and make sure that there are no strict restrictions on Bluetooth system services. Use No Limits mode for stable operation.
💡
Try connecting your headphones to another smartphone. If they're running in stereo, the problem is exactly with your main phone settings, not the headset.
