How to sync headphones Xiaomi Airdots 2 with each other

Budget speakers often face a situation where one earbud stops hearing another. Instead of stereo, you get mono mode or complete silence in one of the channels. It's a classic sign of loss of internal synchronization between the right and left headset modules. Xiaomi Airdots 2 is no exception, and you don't have to bring the gadget to the service center to fix the situation.

In most cases, the problem is a software glitch that can be easily fixed by manually restarting the communication modules, and you'll need to do a series of forced pairings to make your left and right headphones friends again, a process that takes only a couple of minutes, but requires alertness to indicators and accurate timing.

Before you start to take action, you need to make sure that the problem is in the desynchronization, not in a dead battery or break the speaker. Often users try to reconnect the device to the phone, not realizing that the synchronization must occur first between the headphones themselves, and only then they connect to the smartphone as a whole.

⚠️ Warning: Before starting the procedure, make sure that both earphones are at least 30% charged. If the charge is critically low, the pairing process may be interrupted in the middle, leading to re-matching of the channels.

Reasons for desynchronization of headphones Xiaomi

Understanding the nature of the problem helps prevent it from recurring in the future, and the main reason is because of the Bluetooth protocol and the energy-saving algorithms, and when you put your headphones in your case or take them out, they can lose contact with each other if one of the modules goes into deep sleep early.

Also a frequent culprit is connecting to multiple devices at once. If your Airdots 2 has previously been linked to a tablet or other phone, they may try to automatically reconnect with the old gadget, ignoring the current request to create a stereo pair, which creates a priority conflict in the device's memory.

Another factor is interference in the air or software glitches of the smartphone operating system. Updating Android or iOS sometimes changes the logic of the Bluetooth stack, which leads to an incorrect handshake process when connecting, in which cases, a complete reset of the headset settings to factory parameters helps.

• 🔋 The discharge of one of the headphones is below the critical level, which prevents the transmission of the control signal.
• 📡 Active Bluetooth devices nearby that create radio interference or intercept a connection.
• 🔄 Errors in headphone firmware that require rebooting the internal controller.
• 📱 Connection profile conflict when trying to link a headset to a new smartphone without removing the old one.

Preparation for discharge and pairing

Success of the operation 90% It depends on the right preparation. The first step is to clean the list of conjugated devices in your smartphone. 2 (or AirDots BASIC_R) and select "Forget the device" or "Delete" which is critically important that the phone stops trying to connect to the headphones in their current, misguided state.

Then you have to turn off the Bluetooth completely on the phone, and while you're doing the flashing between the modules, any external connection attempts can knock you down. Put both earbuds in the charge case and close the lid on the charge case. 10-15 seconds so that they are guaranteed to go into charging mode and turn off.

Check the contacts. Dirt or oxidation on the charging contacts can cause one earphone to fail to charge and therefore not turn on when removed. Wipe the contacts with dry cloth. Make sure the indicators on both headphones light up when placed in the case.

Step-by-step: how to synchronize Xiaomi Airdots 2

Now, the most important thing is that the forced mating procedure, the algorithm of actions must be done quickly and consistently. Take both earbuds out of the case at the same time. If you do this with a long delay, one of them may have time to turn on the standby mode of connection to the phone, and the synchronization will not start.

Immediately after extraction, start quickly pressing the touchpad of both headphones. You need to make 5 quick presses on each headphone. Do not release your finger after the fifth press - on the sixth press (or when holding after the fifth, depending on the firmware revision), hold your finger for about 5-7 seconds. Indicators should flash red several times, and then go out. This is a signal that a reset has occurred.

Once the lights are gone, put the headphones back in the case. Wait 5-10 seconds. Now pull both headphones out again. At which point they should start looking for each other. The lights will flash white (or blue, depending on the version). When they find each other, one of the lights (usually the right earpiece) will flash slowly, and the other (left) will go out or blink very rarely. This means that the stereopara is created.

Now turn on Bluetooth on your smartphone and start looking for devices. One Xiaomi Airdots 2 device should appear on the list. If you see two devices (for example, with L and R consoles), then the synchronization failed, and the procedure should be repeated, pause between steps a little more.

Sequence of action:


1. Remove both earbuds.




2. 5 times quickly press the sensor of each.




3. At the 5th press, hold your finger 5-7 seconds until red flashing.




4. Put it in the case for 10 seconds.




5. to reach and wait for the connection between them (one flashes, the other does not).




6. Search the Bluetooth phone.

⚠️ Attention: During the sensor pressing procedure, try not to touch the metal contacts on the inside of the headphones so as not to knock off the electrical signal.

Table of indicators and their significance

Understanding color can help diagnose headphones without a phone connection. Different blinking modes report the stage of the pairing process or the presence of errors. Below is a transcript of the basic states for the Airdots 2 model.

Note that blinking speed matters. Fast blinking usually means finding or waiting for a connection, slow blinking is an active connection or playback. Red almost always indicates low charge or reset mode.

Typical errors and methods of their elimination

Even with strict adherence to the instructions, nuances can arise, and users often complain that after resetting, the headphones are seen by the phone as two separate devices: AirDots. BASIC_R and AirDots BASIC_L. This means they couldn't shake hands with each other. Try putting them in the case, closing the lid and repeating the reset procedure, but this time take them out more slowly, almost simultaneously, but with minimal delay in the process. 0.5 seconds.

Another common problem is that only one earbud has sound, although Bluetooth displays connectivity to both. In this case, the "ignor" method will help. Connect the headphones to the phone, make sure that the sound is only coming from one. Then, in Bluetooth settings, tap the gear next to the device and select "Unplug" (not "forget", but temporarily turn off).

Sometimes the Bluetooth cache on the smartphone itself gets in the way. If nothing helps, go to your phone's settings, find Apps, select Show System Processes, find Blueetooth, and click Clear Cache and Clear Data. This won't delete your files, but resets all wireless connection settings, which often solves the compatibility problem.

• 📱 Bluetooth Version Conflict: On Old Phones (Android) 6-7) You can have codec problems. Try changing the default version of Bluetooth or codec in the Developer menu. SBC.
• 🔊 Volume imbalance: If one earbud is quieter, check the "Absolute Volume" settings in the Android developer menu.Sometimes system volume is out of sync with headphone volume.
• 🔄 Cyclical reconnection: If the headphones are constantly blinking and not plugging in, they may have "remembered" another device nearby. Take the phone to another room away from other gadgets and try connecting there.

💡

Useful tip: If you use an iPhone, try using Bluetooth settings to click on the "i" icon next to the headphones, select "Forget the device," then reboot the iPhone itself. Once you turn on the phone, reset your headphones (5 taps) before connecting, which solves 95% of iOS problems.

Features of connecting to different operating systems

The process of syncing the headphones themselves is universal, but the initial connection to the smartphone has nuances. On Android devices, it often requires confirmation of a request for access to contacts and a call log. Without this, the headphones can only work as a headset for music, but not for calls, or vice versa.

iOS owners should remember that Apple has strict control over power consumption. If the headphones are not used for 15 minutes, the iPhone can force the connection to break to save energy, and the headphones will go to a spave. In this case, just touch the sensor to wake up the connection, you do not need to re-mating.

MIUI devices (Xiaomi, Redmi, POCO) have a proprietary pop-up feature when opening a case. However, for the Airdots 2 (basic version), this window may not appear, as it is designed for the more expensive Mi True Wireless series models. Don't think it's a malfunction, just plug them in through the standard Bluetooth menu.

💡

TWS's main principle is that the right headphone (Master) always connects to the phone first and transmits the signal to the left (Slave).

Prevention and care of the device

To keep the desynchronization problem from returning, follow simple rules of operation. Don't let the case battery run completely out. If the case runs out of power, the headphones inside can lose charge faster than usual, causing them to become deeply discharged and the controller to malfunction.

Clean the speaker grid and charge contacts regularly. Earwax and dust, when they hit the contacts, create resistance, which makes the earphone in the case think that it is not charging, and does not turn off correctly. Use a soft dry brush or cotton swab with minimal alcohol.

Keep your headphones dry. Humidity is the enemy of electronics. Sweat or rain can cause internal contacts to oxidize, causing Bluetooth to be unstable and often out of sync. If your headphones get wet, don't put them in the case right away, let them dry at room temperature for at least 24 hours.
