How to disable one headphone Xiaomi: solving problems of desynchronization

When a single Xiaomi headphone stops working or doesn't want to connect to a smartphone, it's familiar to many wireless speakers. It happens suddenly: you take the headset out of the case, and only the left or right channel plays, and users often think that the device is broken and rush to carry it to the service center, although the problem lies in the software failure.

In fact, dissynchronization between modules is a regular, if unpleasant, feature of TWS (True Wireless Stereo) technology. Headphones may have lost touch with each other and now work as two independent monodevices. In most cases, hard resetting helps bring them back to life in a couple of minutes without losing warranty.

In this article, we will discuss in detail all the ways to force disable and reconnect one of the Mi True Wireless headphones. You will learn to distinguish between software errors and hardware malfunctions and understand how to correctly conduct the reset procedure for your particular model.

Reasons for the desynchronization of wireless headphones

Before you start to actively shut down, you need to understand the nature of the error, and most often the problem is that the connection protocol between the left and right modules has been broken, and this can happen if one of the headphones has completely discharged while the other one is still running, or if you have taken them out of the case at different speeds.

Another common cause is Bluetooth connection conflict: If your smartphone was previously paired with this headset, it could have "remembered" the wrong status of the devices. The phone's memory now stores data on two separate devices instead of one stereo pair, which prevents correct operation.

⚠️ Warning: Don’t force the headphone to turn off by simply turning off Bluetooth on your phone.This won’t solve the problem of desynchronization between the headsets themselves, but will only break the connection with the smartphone.

Electromagnetic interference is also a factor to consider: If you are in an area with a lot of Wi-Fi routers or powerful transmitters running, the signal between the headphones can be interrupted, causing them to temporarily disconnect. In rare cases, the software of the smartphone itself is to blame for improperly processing A2DP profiles.

Basic reboot and clean up Bluetooth cache

The easiest and safest method to try first is the full reset loop. Often, it’s enough to simply “forget” the device in your phone’s settings to erase the erroneous configuration files. Go to your smartphone’s Bluetooth menu, find your Xiaomi model in the list, and select “Forget the device” or “Unpair.”

Then put both earbuds in the charge case and close the lid. 10-15 So, you can take a second to get them to standby completely, and then you can reopen the lid, but don't take the headphones out right away, give them time to internalize. If the lights are on, you have a charge, and you can move on to the next step.

Now turn on Bluetooth on your smartphone again and try to search for devices. If you have one device with your model name on the list instead of two identical devices, then the basic reset was successful. If you see two identical names or one doesn't appear, you will need a more in-depth hard reset procedure.

💡

Before re-pairing, be sure to restart the smartphone itself. This will clear the temporary buffer of the Bluetooth module and eliminate software glitches of the operating system.

Hard Reset methods for different models

If a simple reboot doesn't work, you need to start a factory reset of the headset settings. How to execute this command depends on the specific model of your Xiaomi or Redmi headphones. Manufacturers use different algorithms for activating pairing and reset mode.

For the Mi True Wireless Earbuds Basic series (including versions 2 and 2S), the procedure is as follows: remove both headphones from the case. Find a touch or physical button on each of them. Press and hold the buttons on both headphones simultaneously for 5-7 seconds until the indicators flash red. This means that the settings are reset.

For more advanced models, such as the Mi True Wireless Earphones 2 or Air 2, where there is a charge case with a button, the algorithm is different. Put the headphones in the case, leaving the lid open. Find the function button on the case case case case case (usually hidden or located on the end). Press and hold it for 10 seconds until the indicator flashes white.

It's important to do everything consistently and take your time. If you release the button too early, the reset mode will not activate. Once the indicators have gone out or changed color, close the case, wait a few seconds and open it again. Now the headphones should be in pairing mode.

Specificity of the disconnect for models Redmi and Mi AirDots

The Redmi AirDots and Mi AirDots line of budget headphones have their own features that often confuse users. These models often lack a button on the case, and all control is through the touch zones on the headphones themselves, which is where one earphone is most often “lost.”

To force one earpiece in this series to be turned off and reconnected, manual activation is often required. Remove the right earpiece (which is usually a master device) and tap the touchpad 5 times quickly. This action puts it into search mode. Then a similar procedure is done with the second earpiece so that they find each other.

Sometimes this trick helps: turn off Bluetooth on your phone, remove both headphones and press them 2 times to turn them off (usually a red indicator). Then again press and hold 5-7 seconds to turn on and enter pairing mode. Only after that turn on Bluetooth on the phone.

⚠️ Note: When resetting Redmi AirDots headphones, make sure they are not in close proximity to other active Bluetooth devices they were previously paired with to avoid automatically connecting to an "alien" source.

Solving charging and contact problems

Often the reason for "disabling" one earphone is trivial — it just ran out and does not charge in the case. In wireless headsets, contact pads play a critical role. If they get moisture, earwax or dust, the electrical circuit does not close, and the earphone remains discharged.

Carefully examine the metal contacts on the earpiece and inside the recess of the case, wipe them with a dry lilaless napkin or cotton swab slightly moistened with alcohol, make sure that the earpiece sits tightly in the socket and magnets attract it with a characteristic click.

If one of the headphones consistently shows a lower percentage of charge or is turned off first, the problem may be the “memory effect” of the power controller. In this case, it is useful to completely discharge both headphones “to zero”, leaving them on outside the case, and then charge up to 100% when turned off.

💡

Regular cleaning of contacts with a cotton swab prolongs the life of the battery and prevents situations when one earphone stops turning on due to lack of power.

Using the Mi Buds app for diagnostics

For Android smartphone owners, the official Mi Buds app (or Xiaomi Earbuds) is a great tool for managing, allowing you not only to adjust the equalizer, but also to conduct a deep diagnosis of the state of each module, and through the application you can see the exact percentage of charge of the left and right earphone separately.

Firmware is often available in the program interface. If the desynchronization is caused by a software bug, the manufacturer could release a patch to fix this error.

You can also find the function of finding headphones or forced disconnection, which sometimes works more than standard Android tools. If the application sees both headphones, but the sound comes from only one, try changing the sound balance in the application settings or resetting the equalizer settings.

⚠️ Warning: Do not interrupt the firmware update process even if the earphone is “hanging.” Interrupting the data record can lead to irreversible damage to the earphone software.
