Xiaomi’s all-wireless headphones are growing in popularity every year, and the Redmi Airdots remains one of the most popular devices in the budget segment. However, after purchase, users often face the need for proper initial synchronization to ensure stable operation of both headphones at the same time. Incorrect setting can lead to channel dissynchronization when sound is coming from only one ear, or problems with connecting to a smartphone.
The process of configuration of the device does not require special technical knowledge, but requires strict adherence to the sequence of actions. In this guide, we will examine all the steps from extraction from the case to deep tuning through the engineering menu and hidden codes, you will learn how to make the gadget work in mono-headset or stereo mode, as well as how to fix common connection errors.
Before you start pairing, make sure your smartphone is on Bluetooth and visible to other devices.It is also important to check the charge level of the headphones and the charge case, as at low battery voltage, the device may not enter search mode or quickly turn off during the setup process.
Primary pairing and activation of the mode
The most important step is to put the headphones in visibility mode. Unlike many of their counterparts, Redmi Airdots does not have a separate pairing button on the body. To activate the search mode, you need to remove both earphones from the charging case simultaneously. The indicators must light up red to signal the start of the activation process.
Once removed, the device will automatically go into Pairing mode, as reported by a fast-blinking white indicator. If the indicators do not flash, it is possible that the headphones have already been paired with another device or discharged, in which case it is recommended to place them back in the case for a few seconds, and then remove again to restart the detection process.
On the screen of your smartphone in the list of available devices should appear the name Redmi Airdots or Redmi. Airdots_R. It's important to click on the main recording, because the right earpiece acts as a master device, which then broadcasts the sound to the left channel.
- 🎧 Remove both headphones from the case at the same time and wait for the red glow of the indicators.
- 📱 Open Bluetooth settings on your smartphone and start searching for new devices.
- 🔗 Select Redmi Airdots from the list and confirm the pairing request.
- ✅ Wait for the voice notification “Connected” and stop flashing the indicator.
⚠️ Warning: If you hear a voice message "Power on" but there is no white blink, then the earphone has not switched to pairing mode. Try holding the touchpad on the earphone for 5 seconds while it is outside the case to force the search to start.
Setting up touch control and voice commands
Redmi Airdots is controlled exclusively through the touchpads located on the outside of each headphone. By default, the settings may not match your habits, so it's important to know what actions are responsible for. Double tap is usually designed to respond to a call or launch a voice assistant, while triple tap often activates the previous track.
Changing the logic of the sensors on Xiaomi devices with a MIUI shell often requires the use of the additional Xiaomi Earbuds application or analogues from Google Play, since the standard Bluetooth menu has limited functionality. However, the basic commands work at the firmware level of the device itself and do not require software installation.
The voice assistant is activated by long-term retention or triple touch (depending on the firmware version). If you have an iPhone, the system may not correctly recognize commands due to the characteristics of the data protocol, so Siri may need a special setting in the iOS accessibility menu to work properly.
Hidden commands of control
It's worth noting that sensor sensitivity can vary, and if you don't execute commands the first time, you don't push too hard -- a fairly confident, but light touch with your finger -- and dirt or moisture on the surface of the sensor can reduce the accuracy of the response.
Modes of operation: Stereo, Mono and TWS
One of the key features of Redmi Airdots is that it supports different modes of operation. The standard TWS (True Wireless Stereo) mode involves both headphones as a single stereo system. However, the device also supports mono-headset mode, which is convenient for long conversations or when you need to hear the environment.
To use the headphones in mono mode, you just need to pull out one of the cases (usually the right one) and connect it to the phone, and the left earphone remains in the case or off. If you pull out the second headphone later, it will try to sync with the first one, but this process does not always go smoothly without first reset.
In some cases, users are faced with a situation where the headphones work independently from each other (separate stereo mode), and the sound comes from only one channel. This is not a standard mode, but rather a synchronization error between modules.
💡
To save battery power, use your headphones alternately: while one is running, the other is charged in a case, which will increase the total time of listening to music during the day by two times.
| Mode of work | Description | How to activate |
|---|---|---|
| Stereo (TWS) | Both earphones work in sync. | Remove both earphones at the same time |
| Mono | There's only one channel. | Remove one headphone, leave the second in the case |
| Playing | Reduced latency | Fifth touch of the sensor (on supported versions) |
| Search | Interfacing mode with new device | Long-term retention of the sensor (5 seconds) outside the case |
Resetting settings and eliminating desynchronization
The most common problem for Xiaomi Redmi Airdots owners is channel desynchronization, when one earphone stops transmitting sound or works quieter than another, which can occur after a battery is zero, a smartphone update or a failure in the Bluetooth protocol.
To do the reset, you need to place both earbuds in the charging case. Make sure they start charging (red lights are burning). Then, without removing them from the case, press and hold the touchpads on both earbuds simultaneously for 15-20 seconds. The indicators should blink red several times, then go out.
After a successful reset, the headphones will go into search mode (fast flashing white). On the phone, you need to remove the old Redmi Airdots pairing from the list of Bluetooth devices ("Forget the device") and perform pairing again, as in the first purchase, this action clears the internal memory of the modules from configuration errors.
☑️ Checklist for headphone reset
⚠️ Attention: During the reset procedure, do not remove the headphones from the case prematurely. Interrupting the process of holding the sensors can cause the reset to fail and the headphones will remain in a state of error.
Specificity of connecting to iOS and Android
While Redmi Airdots is marketed as a universal device, operating systems handle their connection in different ways. Android smartphones, especially those with a MIUI shell, often have the ability to display the charge level of each headphone separately in a Bluetooth widget.
iPhone users sometimes face a problem when the phone sees two devices: Redmi Airdots and Redmi. Airdots_R. In this case, you need to connect to the version with the prefix R (Right). If you connect to the main name, the sound can only go to one channel, since the stereopara is not formed correctly.
To improve the quality of calls on Android, it is recommended that the developer’s settings check the Bluetooth codec. If you have a choice, it is better to leave SBC or switch to AAC if your smartphone and headphones support this codec. This can improve the quality of voice and music transmission.
💡
The rule of thumb for iOS is to always remove both devices (main and R) from your phone’s memory before repairing to avoid channel addressing conflicts.
There's also an automatic connection feature available on Android devices. If you want your headphones to connect right when you open your case, make sure that Bluetooth settings don't limit your connection to just when you request it. In some versions of Android, it's called "Automatically Connect."
Advanced settings through engineering menu and codes
For advanced users who want to make the most of Redmi Airdots, there are ways to access hidden settings through the Android engineering menu, which allows you to change codec settings, sampling rates and other parameters that affect sound. However, beware: the wrong settings can make the device inoperable.
To get to the engineering menu, open the Phone app and type a special code. For most Xiaomi devices, it is ##6484## or ##3646633#. In the menu that opens, you need to find the Bluetooth-related section (often in the Hardware Testing -> Bluetooth tab).
You can check the signal strength here (RSSI), perform a data transfer test and see MAC-Some users use these menus to reset the Bluetooth stack at the system level if the software resetting of the headphones themselves doesn't help.
