Budget speakers often experience one headphone stop working or devices can't find each other, which creates a sense of failure, although in most cases the problem lies in a software protocol failure. Left-right-handed synchronization is a critical process for sound.
To restore the functionality of Xiaomi Redmi AirDots, you need to perform a series of forced pairing actions, the most effective way is to completely reset the settings through prolonged retention of touch zones, which initiates a reboot of the microcontroller inside each module.
Reestablishing communication between two headphones requires a certain sequence of actions. In this article, we will discuss in detail an algorithm of actions that will help to revive even those devices that seem completely inoperable.
Reasons for the desynchronization of headphones
The main reason for the loss of communication between the right and left headphones is the desynchronization of Bluetooth profiles. When one module connects to the phone, the second can remain in standby mode or try to connect to another device. The Bluetooth protocol in this model implies that one headphone is a master and the other is a client.
Sometimes the problem arises from a software glitch in the smartphone operating system. Updating drivers or changing priorities in the list of associated devices can cause AirDots to stop understanding each other's commands, in which case manual initiation of the reconnection process is required.
⚠️ Warning: Do not try to connect the headphones to the device while they are in the charging case.This can cause address conflict and prevent proper initialization.
Also consider the physical wear of the contacts or battery discharge in one of the modules. If the left or right earphone is discharged more, it may not have time to communicate with the master device.
- 📡 Failure in the Bluetooth protocol when switching between devices
- 🔋 Different battery levels in the left and right modules
- 📱 Program conflict in the smartphone operating system
- 💾 Overflow of memory of the connection cache on headphones
Preparation for the interface procedure
Before you start manipulating, you need to clear your smartphone connection history. Go to your mobile device's Bluetooth settings, search the Redmi AirDots or Mi True Wireless EBs Basic list, and select the "Forget Device" or "Delete" option. This is a critical step.
After deleting the profile, turn off Bluetooth on the phone.This will prevent you from automatically trying to reconnect during setup.Now make sure both earbuds are sufficiently charged.Put them in the case for 10-15 minutes if you're not sure of their power level.
It's important to keep the contacts clean. Wipe the metal dots on the bottom of the headphones and inside the case with dry cloth. Oxidation or dust can prevent the correct transmission of charge and status data.
☑️ Preparation for discharge
Step-by-step instructions for resetting settings
Hard Reset is a universal solution for most communication problems. Remove both earbuds from the charging case. Make sure they're off (the indicators don't burn). If they turn on automatically, turn them off by holding the touch areas for 5 seconds.
Now, press and hold the touchpads on both headphones simultaneously. Hold it for about 20 seconds. The indicators will flash red several times, then go out, and then turn red again. You only need to release the buttons after the second light of the red light.
Then put the headphones back in the case. The indicators on the case should light up, signaling the start of charging. Wait about 10 seconds, then re-extract both headphones. They should automatically pair with each other.
⚠️ Attention: If you release the touchpads too early, reset will not occur.Keep your fingers pressed until the indicator flashes red a second time.
What do the indicators mean?
Reconnecting to the smartphone
After a successful reset, the headphones go into pair-search mode, at which point the indicators on both modules should flash quickly white, which is a signal that the TWS (True Wireless Stereo) mode is activated and the devices are looking for each other.
Turn on Bluetooth on your smartphone and start looking for new devices. The list of available gadgets should appear Redmi AirDots. Note: if you see two identical names, then the synchronization between the headphones did not go through, and the reset procedure should be repeated.
Click on the name of the pairing device. Once successfully connected, the voice assistant will report status (usually the phrase "Connected" or similar), and the music must now be played through both channels.
- 🔍 Make sure there is only one device in the Bluetooth list called AirDots.
- 🎧 Wait until the indicators stop blinking quickly and start flashing less often.
- 📲 Do not bring your phone too close to your headphones during the first pairing.
💡
If the phone sees two Redmi AirDots devices, delete both profiles from the phone’s memory and repeat the reset procedure from the start, paying special attention to the sensor retention time.
Diagnosis (Frequent problems)
Sometimes users are faced with a situation where one earbud is working and the second is silent, even after reset. This may indicate that the second module is asleep and does not go out of power saving mode. Try to put a working earbud in the case, and leave the non-functioning outside.
Then tap the sensor of the broken module 5 times quickly. In some versions of the firmware, this action forcefully wakes the device. If this does not help, check the charging contacts. Perhaps the second earphone just went off to zero and needs time to "rock" the battery.
Problems can also arise from interference in the air. Wi-Fi routers, microwave ovens and other Bluetooth gadgets can create interference. Try setting up in another room or outdoors.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Only one works. | Dissynchronization of channels | Perform Hard Reset (20 seconds) |
| Sees 2 devices. | The headphones are not paired with each other. | Remove from Bluetooth and reset |
| Quiet sound | Dynamic grid contamination | Clean the net with a soft brush |
| No auto-connection. | Memory overload | Clear the list of couples on the phone |
💡
Successful synchronization is confirmed when only ONE Redmi AirDots device is displayed in the phone’s Bluetooth list, rather than two separate devices.
Features of working with different OS
Owners of Android devices may experience aggressive energy saving; the system can kill the Bluetooth service process, considering it inactive; the phone settings for the Bluetooth service (or the Mi Earbuds app, if used) must allow work in the background.
iOS (iPhone) users rarely face compatibility issues, but sometimes face audio delay.This is due to codecs. Xiaomi Redmi AirDots use a standard SBC codec that provides stability, but not always perfect quality when a bad signal is in place.
Windows computers may have driver problems. If your PC sees headphones but doesn't play audio, check the sound settings in the control panel. Make sure the default playback device is installed on Headphones (Redmi AirDots Stereo) rather than Headset (Redmi AirDots Hands-Free AG Audio).
⚠️ Attention: Hands-Free mode AG Audio is only for calls and has poor sound quality.For music, always choose Stereo mode.
Care and malfunction prevention
To avoid the recurrence of connection problems, it is important to store the headphones properly. Always return them to the case after use. This not only charges them, but also turns them off, preventing battery drain and accidental pairing with foreign devices.
Clean the charging contacts regularly. Sweat and skin fat conduct current and can short-circuit between contacts in the case, resulting in incorrect charge determination. Use a cotton swab lightly soaked in alcohol (not in water!).
Don't let the headphones go too deep. If you're not planning on using the headphones for a long time, charge the case and the modules themselves to the top. 50-60% And leave them off. Check the charge level every three months and recharge them.
- 🧼 Wash your contacts with alcohol once a month
- 🔋 Do not keep your headphones completely discharged.
- 📦 Always clean up after listening.
