Headphones Xiaomi Airdots connect separately: how to fix

The situation when TWS-Headphones stop working in pairs and start to reproduce sound independently of each other, is one of the most common problems owners of wireless acoustics. Instead of hearing the stereo mix, the user finds that the left channel is playing in one ear and the right channel is playing in the other, or the devices can’t see each other at all when trying to connect to the smartphone. most often there is a software failure of synchronization between the master device and the plume.

The reason lies in the peculiarities of the data protocol, where one of the headphones (usually the right one) acts as the main one, and the second connects to it. If this bundle is broken, Xiaomi Airdots go into mono-work mode. To restore functionality, you need to perform a forced re-pairing, resetting the current Bluetooth settings and starting the search process again. Below we will discuss in detail the algorithm of actions that will return your headphones to a full stereo.

Why the headphones work in mono mode

The fundamental reason for the desynchronization lies in the fact that each ear of wireless headphones has its own MAC-The address and memory of the last connected device: In normal mode, the right headphone (Master) connects to the smartphone and relays the signal to the left (Slave). When communication between the two is lost, the left earbud can try to plug in to the phone itself, perceived by the system as a separate device. In the Bluetooth list, this is often displayed as "Mi True Wireless EBs." Basic_L" and "Mi True Wireless EBs" Basic_R".

The second reason may be different battery levels, and if one of the ears is completely discharged and turned off, and the second one is still working, when you put them in the case and then remove them, automatic synchronization may not occur, and the stability of the connection is also affected by external radio interference or an active Bluetooth module in the neighboring device that tries to impose its connection.

⚠️ Warning: If the problem persists after resetting and re-pairing, check the charging contacts on the headphones themselves. Oxidation or contamination of the contacts can cause one of the ears to fail to charge in the cack and go into deep discharge, causing dissynchronization.

It's important to understand that software failure may have occurred when you're out of the case, that you could have pulled out your headphones too long, or touched your touchpads, and you could have activated different scenarios, and that the control system perceives this as a command to work independently, so the key is the complete reset procedure, which causes the devices to forget each other and the phone, starting the process of getting to know each other from scratch.

Preparation for the restoration of synchronization

Before you start to do complex manipulations, you need to get the right starting conditions. The first step is to completely clean the list of paired devices in your smartphone. Find in the Bluetooth settings all the records associated with Xiaomi Airdots, Redmi Airdots or Mi True Wireless, and click "Forget the device" or "Delete." This is critical, as old profiles will interfere with the creation of a new master channel.

The second step is to check the charge. Make sure the case is charged, the headphones are sitting tight in the sockets and the indicators are lit red. If one of the ears is not charged, wipe the contacts with a dry cotton swab. Without sufficient charge (at least 30-40%), the synchronization procedure can be interrupted halfway, and the connection protocol will again be lost.

It is also recommended to turn off Bluetooth on the smartphone itself or put the phone in aeronautical mode while setting up, which will prevent the headphones from automatically connecting to the phone during their mutual synchronization, and if the phone intercepts the headphones ahead of time, they will again work as two separate mono-devices, rather than as a single stereo system.

Step-by-step: complete reset and pairing

The most effective way to get the right and left earbuds working together again is to perform a manual reset. For Xiaomi Airdots, Redmi Airdots S and analogues without physical buttons on the body (touch only control), the procedure is as follows: Remove both earbuds from the charging case. They must turn on automatically.

Now you need to touch the touch areas on both headphones simultaneously and hold your finger for about 5-7 seconds. You need to wait until the indicators on both devices do not go out, signaling that you turn off. Then, without letting your fingers go (or pressing again if they turn off), hold the sensors for another 15-20 seconds. Key point: the indicators should flash red several times (usually 2 or 3 times), which means successfully resetting the settings to the factory.

Once the lights are gone, put the headphones back in the case and close the lid for 10 seconds. Then open the case and remove the devices. At which point they should start flashing white quickly, entering search mode for each other. Once one of the headphones (usually the right one) stops flashing or flashes less often, and the second one continues to flash white often, which is a sign of success. So the master channel is created, and now you can turn on Bluetooth on your phone and look for one device, "Mi True Wireless EBs Basic" instead of two.

⚠️ Note: While holding the sensors to reset, the headphones can emit audio signals or voice prompts in Chinese or English ("Power off", "Pairing"). Don't pay attention to them, the main thing is visual control of the color of the indicator (red flashing).

Synchronization Features for Different Models

Xiaomi’s wireless acoustics lineup and its sub-brands (Redmi, Poco) include many modifications, and the reset algorithm may vary slightly depending on the presence of physical buttons. Airdots 3, Redmi Buds 3 Lite or Mi True Wireless Earbuds Basic 2 models, where there is no touch control or it works differently, often require the use of physical keys.

If your headphones have buttons, the algorithm changes: you need to remove the headphones from the case and press the button on each of them (or the button in the case, if it is intended to reset the pair) and hold about 10-15 seconds until the display mode changes. In some models, such as the Xiaomi Air 2 SE, the pair is reset by prolonged pressing (about 20 seconds) on the touch areas of both headphones simultaneously until the indicator lights up in orange.

For advanced models that support Xiaomi Earbuds or Mi Home, the reset can be done software-based through the smartphone interface, if at least one of the ears is connected. However, with full desynchronization ("disparate" channels), the hardware method with the retention of the sensors remains the most reliable. Below is a table of differences in the indication for understanding the status of the device.

Solving problems with connecting one headphone

There are situations where, after a reset, only one headphone is connected to the phone and the other one is silent. This is a classic desynchronization problem where the phone only sees the master device. If you see two devices on the Bluetooth list with the same name or with the name L and R, then the stereo pair is not assembled, in which case you need to delete both devices from the phone's memory again.

Then reset the procedure, but with a focus on retrieving the two earbuds at the same time. If they don't connect together (both flashing white quickly), put them back, close the lid, open and re-extract. Sometimes it takes 3-4 case headphone cycles to get the TWS protocol to prioritize correctly and connect the channels.

If only the left earbud connects and the right is silent, try connecting the left to the phone first, play the sound, and then, without turning off Bluetooth, pull the right one out of the case. In some firmware, this causes the right earbud to look for an active connection and "attach" to the left one as a secondary device, restoring the stereo.

💡

Try connecting your headphones to another smartphone. If they're stereo on another device, the problem is your main phone's Bluetooth cache, and then clearing the Bluetooth cache in your Android settings will help -> Annexes -> Show system-based -> Bluetooth -> Memory -> Clear the cache).

Software conflicts and firmware updates

Sometimes the problem is not the hardware, but the software. Outdated headphone firmware can contain bugs that cause unstable connections. For models that support the Xiaomi Earbuds app (for the global market) or Mi Home (for the Chinese market), it is worth checking for updates.

Connect your headphones to your phone, open the app, and find the firmware Update section. If a new version is available, install it by putting your headphones in your case and plugging the case into charging (or making sure it's fully charged). The upgrade process can take 10-15 minutes, at which time you can't open the case lid or zoom the smartphone too far.

Also worth paying attention to is the version of Android or iOS on your smartphone. Sometimes, after upgrading the phone's operating system, old Bluetooth encryption protocols can conflict with the headphones. In such cases, removing the device and re-pairing, as described at the beginning of the article, helps. A critical factor in stability is the version of the smartphone's Bluetooth drivers, which cannot be updated separately from the system, so keeping the OS up-to-date indirectly affects the operation of accessories.

⚠️ Warning: Do not interrupt the process of updating the firmware of the headphones. If the battery sits down or the connection breaks down during the recording of new data, the headphones can turn into a "brick" and stop turning on, requiring a difficult recovery in the service center.
