Modern wireless headsets, especially popular models from Xiaomi and Redmi, often face a situation where one of the headphones stops syncing with the smartphone. The user can hear sound from only one side, which makes listening to music or talking uncomfortable. This is a common problem of TWS (True Wireless Stereo) technology, which is solved by the correct reset and repair procedure.
In most cases, headphones simply forget each other and try to connect to the phone as two separate mono-devices. To return stereo, you must force them to combine into a single pair. Below we will discuss a detailed algorithm of actions that will help restore the headset and avoid typical errors in the setting.
Don't panic if the lights don't flash as described in the manual, or if the phone only sees one device. Mechanical failure is rare, most often failure occurs at the software level. A critical condition for successful recovery is to fully discharge both headphones before starting the reset procedure, which ensures that the error buffer is cleared and pairs are searched correctly.
Preparation for the restoration of synchronization
Before you start complex button manipulations, you need to make sure that the equipment is ready. Often the problem lies in oxidized contacts or different levels of charge, which causes one earphone to go to sleep prematurely. Carefully wipe the contacts on both devices with dry cloth and install them in the charging case for at least 30 minutes.
In parallel with charging your headphones, clean up the Bluetooth list on your smartphone. Find a previously saved device, such as Redmi Buds 3 or Mi True Wireless Earbuds, in your settings, and select the option “Forget the device” or “Delete” that will remove old encryption keys that may interfere with the new connection.
⚠️ Warning: Do not try to plug the headphones while they are inside the charging case. Some models only start pairing mode after removal, others require that they be inside. Always check the specifics of your model, but a classic reset is usually done outdoors.
Make sure your phone turns off Bluetooth before you start the procedure, which will prevent automatic connection at the time of reset, which can interrupt the synchronization process between the left and right channels, and completely insulating the headset from external signals is key to success.
Algorithm of a complete reset of TWS headphones
Hard Reset is a universal solution to most communication problems, bringing the device back to factory settings, forcing the left and right headphones to re-experience each other. The sequence may vary slightly between Xiaomi and Redmi models, but the basic principle remains the same.
Take both earbuds out of the case at the same time. If they don't respond, they may be discharged. If the lights are on or flashing, press the touch zones on both earbuds simultaneously. Hold them for 10 to 20 seconds. In some models, such as the Mi True Wireless Earphones 2, you need to touch the sensor 5 times quickly.
Watch for the indication: usually after a successful reset, the indicators start flashing red and white alternately or flashing white quickly, and this is a signal that the headset has switched to pair-search mode, so you can turn on Bluetooth on your smartphone and start searching.
- 🔘 Press the sensors for 15 seconds before changing the color of the indicator.
- 🔘 Quickly press 5 times on the sensor to activate the pairing mode.
- 🔘 Hold physical buttons on the body (for models with buttons).
- 🔘 Use the button on the case, if it is provided by the design.
Specificity of connecting different models Xiaomi
The Chinese giant's audio lineup is extensive, and each segment has its own control features.Redmi Airdots' budget models often require longer sensor retention, whereas the flagship Mi Buds may have a separate button on the case to reset.
The Airdots S and Basic series have a problem with one headphone remaining in mono mode, and this is where the double-on method helps: after reset, put both headphones in the case, close the lid, wait 10 seconds and pull them out at the same time. They must flash blue twice, which means successful synchronization with each other.
Secrets of models without a button on the case
If your charger case doesn't have a physical reset button, all the magic happens through touch control. You'll have to be agility to press both headphones at the same time.

This often happens when watching videos or in games where audio delay becomes noticeable. First of all, check the sound balance in the special features settings of your Android smartphone. Go to Settings → Special facilities → Rumor → Make sure the slider is in the middle, and if the balance is knocked down, the phone will send the entire audio stream to just one channel, giving the illusion that the headset is broken. Another reason could be the low battery charge in one of the headphones, and the system can automatically turn off the discharged module to save energy. Charge the case and headphones completely using the original cable, as powerful chargers for phones can damage the power controller of the low-power garn tour. ⚠️ Warning: Avoid using chargers with currents above 1 Amp to charge a case of headphones. High current can cause the battery to overheat and fail, making it impossible to connect one of the headphones. Sometimes users accidentally activate mono-phone mode, thinking that the second headphone broke. In this mode, both headphones work independently or the sound is reduced to one channel. To turn off this feature in Xiaomi smartphones with a shell MIUI HyperOS needs to go to Bluetooth settings. Find the connected device in the list and click on the gear icon or arrow to the right of the name. In the menu that opens, make sure that you do not check the "Mono-audio" box. If this option is not available in the Bluetooth menu, check the "Special Opportunities" section in the general system settings. For some Redmi models, there is a hidden triple-touch mode. Check the instructions for your particular model to keep useful controls from turning off. If you haven't used triple-touch, chances are the problem lies deeper in the system. 💡If after all the manipulations the sound remained monophonic, try to connect the headphones to another device (tablet, laptop), this will help you to understand where the malfunction is: in the headset or in the smartphone. Software conflicts and firmware updates Modern headphones are mini-computers with their own operating system. Firmware bugs can cause periodic shutdowns of one channel. Manufacturers regularly release updates that improve connection stability. Use the official Mi Wear app (for global versions) or Xiaomi Earbuds (for Chinese versions) to update. Connect your headphones to your phone, open the app and check for updates. It takes a few minutes, where the headphones are supposed to be next to your phone. If the update doesn't work, try clearing the Bluetooth cache on the phone itself. Go to Settings. → Annexes → Show all applications → Bluetooth → Memory. → Clear the cache. Then restart the smartphone. This action will reset all temporary files that are responsible for the operation of wireless modules. 💡Updating the firmware of headphones through the official application solves 80% of software problems with communication and sound quality. Frequently Asked Questions (FAQ) Why does the phone see two devices with the same name? This means that the headphones have lost communication with each other and are operating independently. You need to perform a full reset so that they reunite into one stereo pair before connecting to the phone. Can you use only one Xiaomi headphone? Yes, most models support Mono mode. To do this, just take out one headphone from the case. However, to return to the stereorerereset, you need to put both headphones back in the case and get them out at the same time. What if one headphone is a flasher? How does one headphone not get a flashlight from the other, and you probably have a bad one from the battery charger, and you have a 1? Usually, the inside of the leg or body is marked L (Left) and R (Right), and when connected, the Bluetooth settings often display the charge of each earphone separately, allowing you to identify them.
