Owners of wireless headsets from the Chinese giant often face a situation where the right and left channels stop working in pairs. This is a common problem, requiring the right sequence of actions to restore functionality. Synchronization is a process that is easily disrupted by a random touch or glitch in Bluetooth software.
Modern models like AirDots, Redmi Buds and the flagship Mi True Wireless Earbuds use complex communication protocols. If one earbud doesn't "hear" the other, the sound will come from only one channel or monophonically. You don't have to carry the device to the service, because in 90% of cases, the problem is solved by manual resetting.
In this article, we will look at all the nuances of how to make your headphones work in tandem again, we will look at the algorithms for different series of devices and eliminate the typical mistakes that users make when trying to pair.
Reasons for the desynchronization of the right and left earphone
Before you start doing something, you have to understand the nature of the failure, and often the problem is that one of the batteries is actually actually going to run out of power, and if one of the headphones went out faster than the other, it could shut down and exit the pairing mode while the other one was still running.
Another common cause is signal interference, and if you're in a place with a large concentration of Wi-Fi routers or other Bluetooth devices, communication between channels can be interrupted, especially for models running in the 2.4 GHz band.
⚠️ Note: If you notice that headphones lose communication only in certain places (office, shopping center), the problem may not be in the device, but in the noisy air.
Also worth mentioning are the software glitches of the smartphone itself: Updating the Android or iOS operating system sometimes changes the algorithms of the Bluetooth stack, leading to conflicts with old connection profiles, in which case removing the device from the list of conjugated gadgets helps.
💡
Always keep the headphone case charged. If the case goes to zero, the headphones inside may lose sync with each other the next time you pull it out.
Basic preparation before setting up
Before you try to combine Xiaomi headphones, you need to perform a number of preparatory steps, which will eliminate false positives and speed up the process. First of all, make sure that your smartphone is on Bluetooth and it is visible to other devices.
Put both earphones in the charger case and close the lid. 10-15 This action will force the Bluetooth modules inside the headset to shut down and restart their internal logic.
Go to your phone's Bluetooth settings. Find your model (e.g. Mi True Wireless EBs Basic) in the list of previously saved devices. Click on the gear or information icon and select "Forget Device" or "Disable" option.
☑️ Preparation for reconnection
Then turn off Bluetooth on your phone completely, which is an important step to prevent the phone from automatically connecting to one of the headphones as they pair together internally, and then you can move on to the basic methods.
Coupling methods for different Xiaomi models
How Xiaomi headsets are connected depends on the specific series of devices, and the company's engineers use different algorithms for budget and premium lines.
AirDots (1 and 2 generation) and Redmi Airdots often require manual initiation of the mode (pairing), usually by long-term retention of touch zones or mechanical buttons. If there is a button on the body, press it for 5-7 seconds before the indicator blinks.
In newer models, such as the Mi True Wireless Earbuds Basic 2 or Redmi Buds 3, the process is often automated. Just remove both headphones from the case at the same time. They must find each other within 5 seconds, as signaled by the rapid flashing of indicators.
The secret to fast synchronization
If the automatic mode did not work, use the universal method with a button on the case (if any). Press the button on the back of the charging case for 10-15 seconds. The indicator should light up in orange or white, signaling the transition to Pairing mode.
Step-by-step: Full reset (Hard Reset)
When standard methods fail, you need to perform a full factory reset, which clears the internal memory of the headphones of all stored profiles and configuration errors.
Put both earbuds in the charger case. Make sure the contacts are clean and the headphones start charging (lights are on). Leave them in the case for 10 seconds to stabilize power.
Now press and hold the touch zones on both headphones simultaneously. 20-30 First, the lights can flash, then they can go out, and then they can light up again, and you only have to let them go after the lights are flashing. 2-3 red-white.
| Model headphones | Action for discharge | Indication of success |
|---|---|---|
| Mi AirDots / Redmi Airdots | Hold sensors for 20-30 seconds | Triple flashing. |
| Mi True Wireless 2 / 2S | Case button 10 seconds. | White flashing |
| Redmi Buds 3 Pro | Hold sensors for 10 seconds. | Orange light |
| Mi Buds 3T / 4 | Case button 2 seconds + sensors | Light pulsation |
After reset, the lights should go out. Put the headphones back in the case, close the lid and wait 5 seconds. Now open the case, the headphones should go into search mode for each other. One of them will flash faster, indicando, that he is looking for a "partner."
⚠️ Warning: During the reset process, do not remove the headphones from the case prematurely. Interrupting the procedure may cause the microcontroller to software freeze.
Connecting to a smartphone after synchronization
Once you’ve made sure the headphones are connected (only one light flashes or they flash in sync slowly), you can turn on Bluetooth on your phone. The list of available devices should show one headset name, not two separate ones.
Click on the name of the device to connect. If the system requests a pairing confirmation, click OK or Connect. In some cases, you may need to enter PIN-The standard code is 0000 or 1234.
Once you've successfully connected, check the sound. Play music or video. The sound should be stereo. If it's monophonic or it's only coming from one ear, repeat the reset procedure, taking more time to hold the buttons.
💡
Key point: A successful connection is confirmed by the fact that the phone’s Bluetooth list displays ONE device, not two identical names.
For Android users, it will be useful to install the Mi Buds M8 or Xiaomi Earbuds app. These utilities allow not only to manage settings, but also to update the firmware of the headphones, which often eliminates bugs communication.
Solving Typical Problems and Errors
Even after doing all the steps correctly, there may be nuances, like the phone seeing the headphones but not connecting, in which case, try rebooting the smartphone itself, which will update Bluetooth services and clear the cache of connections.
If one earphone is discharged more than the other, they may refuse to sync. 30-40 Differences in battery charge can block the pairing process TWS-headset.
Another rare issue is profile conflict: If you've previously connected these headphones to another phone that's right next to you and on, they may be trying to connect to it. Make sure other devices with Bluetooth enabled are away.
⚠️ Warning: Don't try to connect headphones of different models with each other.The left earphone from AirDots 1 will not work in pairs with the right one from AirDots 2, even if they look the same.
In the case of a problem that doesn't work, it's probably a hardware problem. Check the charging contacts in the case. If they're contaminated, the headphones may not charge until the end, which simulates a software failure. Wipe the contacts with a dry cotton swab.
