How to connect two headphones Xiaomi Airdots with each other

When wireless headphones stop working in pairs, that's familiar to many budget speakers, because instead of stereo, you hear music in one ear, and the other one is silent or broadcasting a mono signal, which means that the right and left channel have lost communication with each other and are working independently, most often after one module has been discharged, a Bluetooth protocol has failed, or a device has been accidentally paired with another.

Fortunately, you can restore normal operation of the Xiaomi Mi True Wireless Earbuds Basic headset (formerly known as Airdots) on your own, without visiting the service center. The process does not require complex tools, but requires precise adherence to the sequence of actions. In this article, we will discuss all the nuances of synchronization, from simple reconnection to a complete reset (Hard Reset).

Before you start complex manipulations, make sure that the problem lies in the software rassynchon, not in the hardware breakdown. Bluetooth modules inside the case and the headphones themselves are quite sensitive to contamination of contacts. If metal charging pens formed oxide plaque or got moisture, the devices may not “see” each other physically while in the case. Wipe the contacts with dry limpless fabric before starting the procedure.

Preparing devices for synchronization

The first step is to completely clean up the list of stored devices on your smartphone. While the phone tries to automatically connect to the broken headphone configuration, you can't reconfigure them. You need to go to the Bluetooth settings, find the Xiaomi Earbuds list. Basic_R Or Right, and select "Forget device" or "Delete" -- the same thing if you have a second headphone left on the list.

Once you delete your phone profiles, turn off Bluetooth on the smartphone itself. This is a critical point: the phone's radio module should not be emitting search signals while setting up the headset. If Bluetooth remains on, the headphones can connect to the phone in mono mode before you pair them together in a stereo pair.

💡

Make sure that both earbuds are charged at least 50% before setting up, so that the process does not stop due to the discharge at the most inopportune moment.

Now, put both earbuds in the charge case and close the lid. Let them lie there. 10-15 This is to make them completely de-energize and standby. Then remove both earbuds at the same time. If they start flashing white at different intervals or don't respond at all, that's why you need to manually solder the connection.

The double reset method (Hard Reset)

The most effective way to get Mi True Wireless Earbuds back to work in pairs is to perform a full reboot. There are two main options for this procedure, depending on the specific revision of your headphones. Most modern models use a method with long-term retention of touch panels.

Remove the headphones from the case. If they turn on (the indicators light up), press the touch areas on both headphones simultaneously. Hold on for about 5-7 seconds until the indicators go out. Don't let your fingers go out right away! Continue to hold the sensors for another 15-20 seconds after turning off. At some point, the indicators should blink red and then white several times. This is a signal that the reset has been successful.

⚠️ Note: If one earphone continues to flash red and white alternately after reset, and the other one is silent, then they are not synchronized. Try repeating the procedure, but this time hold the sensors a little longer (up to 30 seconds).

Some older versions of firmware may have different algorithms. If prolonged retention didn't work, try an alternative method: press and hold the sensors until the indicators turn red (off). Immediately after turning off, release the sensors, then press and hold them again for about 2 seconds to turn on the headphones, at which point an automatic attempt to pair the left and right modules should occur.

The process of combining left and right channels

When the reset is successful, the headphones go into pair-finding mode, at which point one of them (usually the right one, the master device) flashes white quickly, waiting for the second one to be connected. The left earphone may flash less often or have a different glow rhythm, and your task is to wait for them to "find" each other.

This process usually takes 5 to 10 seconds. When the connection between the L and R modules is established, the indication will change. The right earpiece (master) will continue to blink slowly white, signaling readiness to connect to the phone. The left earpiece (slave) should go out or blink very rarely (once every few seconds), which means successful audio stream from the right channel.

If the visual indication shows that the pair is created (one flashes, the second almost does not burn), you can turn on Bluetooth on your smartphone. Basic_R. Note that after a successful connection, there should not be two identical names on the list. If you see two devices with the same name, then the stereopara is not assembled, and you need to reset again.

It is important to understand the difference in the behavior of indicators for different generations: the first generation (Airdots 1) models have a white indicator that burns constantly while working, and the second generation (Airdots 2 / Redmi Airdots) it flashes quickly when searching and slowly when waiting for connection, knowing this feature helps not to confuse mode with error.

Features of Airdots 1, 2 and Redmi Airdots

Budget line TWS-Xiaomi's headphones are constantly being updated, and different versions use different chipsets and algorithms, which affects how channels are paired. For example, in the very first generation of Airdots, there was often a problem when the left earphone just “falls off” and stops responding to commands.

Redmi Airdots 2 is more synchronized, but it is more sensitive to interference from other Wi-Fi devices. If you have a router near the charging point, try moving the headphones to another room while you set up. In the Pro version, the reset procedure may require sensors to be held for up to 30 seconds, as it loads a more complex software module.

Some users note that the work of the headphones is affected by the version of the smartphone operating system. On Android 10 and above, the reconnection process can take place automatically immediately after extraction from the case, if a reset was not performed beforehand. On iOS devices sometimes require manual removal of the profile even after resetting the headphones themselves.

Common Errors and How to Resolve Them

Even with strict adherence to instructions, users sometimes find that the headphones do not connect. One of the most common mistakes is trying to connect them while Bluetooth is active on the phone. A smartphone can intercept one of the headphones while he is still looking for a pair and block the possibility of creating a stereo connection. Always start with Bluetooth turned off.

Another common problem is different battery charge: If the right earbud is 10% charged and the left earbud is 90% charged, the connection protocol may not start because the potential difference or software constraints will prevent them from combining. Charge both modules in the case to the full indicator (usually lit red, then go out or turn green).

⚠️ Note: Do not try to connect headphones if one is in the case and the other is outside. Both modules must be removed simultaneously and in close proximity to each other. 10-15 centimeter).

Also worth mentioning are software conflicts: If you've previously used these headphones with another phone and it's within range, they may be trying to connect to it. Make sure all previously paired devices are out of reach or off.

Connection quality check and balancing

Once you have managed to combine two Xiaomi Airdots headphones, you need to check the sound quality. Turn on music with clearly distinguishable stereo effects (for example, tracks where the instruments are separated by channels). Walk around the room, moving away from the phone. A stable connection should be kept at a distance of up to 10 meters without obstacles.

Note the latency of the sound when watching the video. If the out-of-synchronization occurred due to a firmware failure, the delay should disappear after the reconnection, and if the sound is interrupted or stuttered, it may be a problem with radio interference or low battery charge of one of the modules.

💡

A successful connection is confirmed when ONE device is displayed in the phone’s Bluetooth menu and music is played in both ears in stereo mode.

To make a final check, you can run a voice recorder or video camera and record the sound, closing the microphone in turn from different sides, which will help make sure that both microphones (if they are in the model) and speakers work correctly and synchronously.

Preventing desynchronization in the future

To make the problem of "separating" headphones less of a concern for you, follow simple rules of operation. First of all, always put the headphones in the case immediately after use. Do not leave them on the table, as this leads not only to discharge, but also to the accumulation of errors in the Bluetooth stack of the device.

Clean the contact areas in the case and on the headphones themselves regularly. Use a dry cotton swab. Contact oxidation is the main reason that the headphone in the case does not charge or turn off, which eventually leads to desynchronization the next time you turn on.

Try not to drop the case with the lid open. Mechanical impact can disrupt the contact between the headphone and the charging saws, which makes the device not realize that it is placed on the charger, and will remain on, losing charge and communication with the pair.
