Modern wireless headphones such as the Xiaomi Redmi AirDots (including versions of the S, 2, Pro and Mi True Wireless Earbuds Basic) have become incredibly popular due to their availability and sound quality. However, users often face a situation where the device only works on one side, or the phone sees two separate devices instead of one stereo complex, which is puzzling, because it is expected that the wireless headset should work as a whole immediately after extraction from the case.
The problem with desynchronization is often that the right and left earbuds have forgotten each other and are trying to work independently. Instead of stereo, you get mono sound in only one ear, and the second one is silent or plays the same track with a delay, and to correct this, you need to perform a series of actions to force synchronization and reset the settings to factory settings, which will return the devices to the ability to communicate with each other.
In this article, we will take a look at all the steps of connection, from initial pairing to complex resets if standard methods don’t work. You will learn how to use touch panels, status indicators and Bluetooth system settings correctly to restore the full operation of your headset.
Primary preparation and activation of headphones
Before you try to connect the Xiaomi Redmi AirDots to your phone, make sure that both modules are charged. Often one of the headphones is discharged to zero and does not turn on, which makes it impossible for the system to create a stereo pair. Place both devices in a charging case and connect it to the power supply for at least 15-20 minutes. The indicators should light up red during charging and go out or change color when fully charged.
After charging, remove both earbuds from the case at the same time, at which point they should automatically turn on, as the indicators will signal. Pay attention to the blink: if the devices blink white alternately or quickly, this means search mode. If only one indicator is on, it is possible that the second earbud is not activated or is in sleep mode.
⚠️ Warning: Don't take your headphones out one at a time, and if you get the left one and the right one first, they may not be able to sync and start looking for different Bluetooth devices.
For successful activation, it is important that both modules are removed from the case within a short period of time (literally 1-2 seconds), which gives them the opportunity to shake hands with each other before they start scanning the airwaves for your smartphone. If you see the indicators flashing synchronously or one after the other at a certain frequency, then the TWS (True Wireless Stereo) mode is active.
💡
If the indicator on one of the headphones does not light up after removal, try to press it slightly in the case to check the contact with the charging pins.
The process of pairing with Android and iOS
The process of connecting to a smartphone is almost identical to Android and iOS operating systems, as it uses the standard Bluetooth protocol. Open your phone's settings and go to the Bluetooth section. Make sure the power slider is activated and the phone starts searching for available devices around.
The list of available devices should show the name of your model, for example, Mi True Wireless EBs Basic or Redmi AirDots. Importantly, if you see two identical names on the list (for example, two AirDots or L and R separately), this is a sign that the headphones are not paired with each other, in which case, connecting to one of them will give sound in only one ear.
After clicking on the device name in the list, the system will request a confirmation of pairing. Press "Plug" or "Pair." At which point the headphones can request a voice confirmation or simply emit a characteristic success sound. If the connection is successful, the voice assistant will say "Connected", and the headphone indicators should stop blinking and burn dull or go out, signaling the connection stability.
☑️ Checklist of successful pairing
It is worth noting that some Xiaomi models require confirmation of pairing through the system window, which pops up on the smartphone screen. If you missed this window, the connection may not be established until the end, in which case, remove the device from the saved list (forget the device) and repeat the procedure again, carefully watching the phone screen.
The solution to the problem: only one headphone works
The situation when after connecting the sound comes from only one headphone, is the most common complaint of budget owners. TWS-This is because the left-right interface is out of sync, the right-hand interface is usually connected to the phone, and the left-hand interface is connected to the right, and if that link is broken, the second channel is inactive.
The first step in solving this problem is to remove the device from the phone's memory. Go to Bluetooth settings, find your Redmi AirDots and select the "Forget" or "Unpair" option. After that, turn off Bluetooth entirely on the smartphone. Now place both headphones back in the charging case and close the lid (if any) or just leave them in the contacts for 10 seconds.
⚠️ Warning: Before resetting, be sure to delete the headphone profile from the phone's memory. If you don't, the phone can automatically reconnect to one module before they sync with each other.
Next, you need to perform a hard reset. To do this, while the headphones are in the case (or outside it, depending on the model, but more often outside), press and hold the touch panels on both headphones simultaneously for 20-30 seconds. The indicators should flash red several times, and then light up white (or red and white alternately).
Why does not the reset always help the first time?
Synchronization of left and right channel (TWS Pairing)
The key to the stereo system is the right TWS-After you do the reset, when the lights start flashing quickly, don't be too quick to turn on Bluetooth on your phone. 5-10 And then they have to stand next to each other on the table for a second, and then they have to find each other and connect together in a network.
A sign of successful synchronization between each other (before connecting to the phone) is the change in the rhythm of the flashing indicators. They usually start flashing slowly (every 2-3 seconds) or one of the indicators goes out while the second continues to blink (meaning that it has become a master device and waits for connection). If the blinking remains fast and frequent on both modules, then they do not see each other.
In some cases, this lifehack helps: connect your headphones to your phone, then turn off Bluetooth on your phone. Then reset the sensors again. When the indicators go into slow blinking mode, only then turn on Bluetooth on your smartphone and look for the device, which ensures that the priority for the headphones will be finding a partner on the stereo pair, not the phone.
💡
The main secret of synchronization is that headphones must make friends with each other before they connect to a smartphone, and the rush to turn on Bluetooth on the phone often breaks this process.
Diagnostics and indicator table
Understanding the Xiaomi Redmi AirDots color display makes it much easier to diagnose problems. Different blink modes tell the user about the current status of the device. Below is a table that will help decipher your headphone signals and understand where the connection process is.
| Color of indicator | Blinking mode | Importance of status |
|---|---|---|
| Red. | It's burning all the time. | Charging is in progress. |
| Red. | It's gone. | Charging complete (100%) |
| White | Fast blinking. | Interconnection mode (device search) |
| White | Slow blinking | Device is connected or waiting to be connected (TWS is active) |
| Red + White | Alternate flashing | Resetting mode or critical synchronization error |
If you see non-standard behavior of indicators, for example, they do not light up at all or flash chaoticly, this may indicate a hardware malfunction or a deep battery discharge. In the case of a deep discharge, leave the headphones in the case on charging for 1-2 hours, even if the indicators do not respond immediately.
Also worth checking the contacts. Oxidation or contamination of the gold contacts on the headphones and inside the case can prevent charging and transferring data. Wipe them with a dry soft cloth or cotton swab dipped in alcohol. Clean contacts are the key to stable electronic filling.
Additional settings and optimization of sound
After successfully connecting both headphones, it is recommended to check additional settings in the smartphone to improve the sound quality. In Settings → Bluetooth, find the AirDots connected and click on the gear or information icon next to the name. Here you can change the usage profile (for example, select Music instead of Calls, if media is given priority).
If your phone and headphones support AAC or aptX codec (although basic AirDots usually run on SBC), make sure that the Developer Options menu selects the best codec for better audio quality. However, for most scenarios, the standard settings are the most stable.
Don’t forget to update your headphone firmware if the manufacturer is releasing updates through the Mi Wear or Xiaomi Earbuds app. While basic models rarely receive updates over the air, having a current app can help in fine-tuning touch controls and fixing software bugs.
⚠️ Warning: Do not use third-party bass enhancement apps or equalizers with aggressive settings immediately after you connect.This can create the illusion of a speaker malfunction.
