Xiaomi Redmi Airdots 2 wireless headphones have become one of the most popular models on the market due to their excellent price-performance ratio. Many users face difficulties in pairing with the first pairing, as the process has its own nuances that distinguish them from conventional Bluetooth headsets. Proper synchronization of left and right headphones between themselves is a critical step before connecting to a smartphone.
In this article, we will take a look at all the steps of connection, look at possible errors and how to fix them, you will learn how to activate the pairing mode if the indicator does not flash, and what to do if the phone sees only one playback channel, following the algorithm will help avoid common problems with the Bluetooth protocol.
It's worth noting that the Airdots 2 (also known as the Redmi Airdots Basic 2) uses TWS (True Wireless Stereo) technology, which means complete channel independence. This requires a special procedure to pair the headphones themselves with each other before going on the air to search for your phone, and ignoring this step often leads to dissynchronization of the sound.
Preparation of headphones and smartphone for work
Before you start actively searching for the device in the phone settings, you need to make sure that both components of the system are ready. Charge the case and the headphones themselves, as at a low charge, the Bluetooth module can work unstable or not turn on at all. The indicators on the body should burn red during charging and fade or change color when fully charged.
Turn on Bluetooth on your mobile device. To do this, go to Settings → Bluetooth and activate the slider. Make sure your smartphone is not currently connected to other audio headsets that can intercept the signal. This is especially important for Android and iOS devices that are looking to automatically restore the last connection.
⚠️ Note: If the headphones were previously paired with another phone, they may try to connect to it automatically.Stop Bluetooth temporarily on the old device or remove Airdots 2 from the list of stored devices on it.
Remove both headphones from the charge case at the same time. They should light up indicators: red means waiting for connection or charging, and white (or dull blue) blinking signals the search mode for pairs. If the indicators do not light up, check for protective films on the charging contacts, which often remain on new devices.
💡
Before first use, wipe the contact areas on the headphones and inside the case with dry cloth to ensure reliable contact and correct charge determination.
The process of primary pairing with the device
The main step of setting up is to start the search mode correctly. Once removed from the case, the headphones must automatically switch to pairing with each other. This usually takes 5 to 10 seconds, after which one of the headphones (most often the right one) will flash white at a low frequency, which means that they are ready to connect to the phone.
Open the list of available devices on your smartphone and search the list for the name Redmi Airdots 2 or Mi True Wireless EBs Basic 2. Click on the name to start the connection procedure. In the process, you may receive a request for confirmation of pairing - agree with it. Successful connection is confirmed by a voice message "Connected" and a characteristic beep.
☑️ Checklist of successful connection
If the list of devices shows only one headphone or two of the same name, this is a sign of desynchronization, in which case you need to remove the device from the Bluetooth list on the phone, put the headphones in the case, close it, wait 10 seconds and repeat the extraction procedure again, sometimes you need to perform a full reset, which we will talk about below.
Setup of functions and sound management
After a successful connection, the user gets access to basic control, but to expand the functionality, it is recommended to install a specialized Xiaomi Earbuds application (for Android) or use standard Bluetooth settings (for iOS), this allows you to check the charge level of each headphone separately and update the device’s firmware if the manufacturer has released new patches.
Playback is controlled via touch or mechanical buttons (depending on the revision) on the headphone case. Single tap usually pauses the track or resumes playback, double switches to the next track, and triple returns to the previous one.
| Action. | Right earpiece | Left earpiece |
|---|---|---|
| Single tap | Pause/Reproduction | Pause/Reproduction |
| Double-push | Next track | Previous track |
| Triple press. | Activation of the assistant | Activation of the assistant |
| Holding 2 seconds | Dismissing the call | Take on the challenge |
Latency (Latency)
If the sound is quiet even at maximum, check if the minimum volume is set on the mobile device itself. Some smartphone models allow you to separately adjust the volume of media and the volume of Bluetooth devices in advanced audio settings.
Problem Solving: Only one headphone is visible
One of the most common problems Xiaomi Airdots 2 owners have is when the smartphone sees and connects to only one channel (usually the right one), while the second one is silent.This happens when the synchronization between the left and right modules is disrupted and they work as two independent mono-devices, rather than as a stereoopara.
To fix this problem, you need to perform a forced soldering of the channels. First remove the Redmi Airdots 2 from the list of conjugated devices on the phone and turn off Bluetooth. Put both headphones in the case, then pull them out at the same time. Quickly press 5 times on the touchpad of each earphone (or press the buttons if the model is mechanical) until the indicators flash red several times. This will trigger reset mode.
⚠️ Warning: Keep your headphones close to each other (at a distance) during reset 10-20 They have to find each other and sync before reconnecting to the phone.
Once the lights go into rare flashing mode (one flashes, the second does not burn or flashes less often), turn on Bluetooth on your phone again and search. Now one device should appear on the list that combines both channels, connecting to it will restore stereo sound.
Reset to factory settings (Hard Reset)
If standard reconnection methods do not help, or the headphones behave incorrectly (intermittent sound, no response to buttons), it is recommended to perform a complete reset.This procedure returns the internal memory of the headphones to the original state, removing all saved profiles and settings of the equalizer.
Place both earbuds in the charge case. Make sure they are locked and in contact with the charging pins. Press and hold the touchpads (or mechanical buttons) on both earbuds simultaneously for a period of time. 20-30 The indicators should flash red several times before they go out.
💡
Full reset solves 90% of software errors associated with the freeze of the Bluetooth module or desynchronization of stereo channels.
After the procedure, the headphones will automatically go into pairing mode. You need to re-find them in the Bluetooth list of the smartphone, as when you first turned on. Remember that the name of the device in the list can be reset to the default Mi True Wireless EBs Basic 2.
Features of connecting to iOS and PC
Connection to Apple devices (iPhone, iPad) is the standard algorithm, but there are nuances in the display of battery power. The standard Bluetooth menu in iOS does not always show the exact percentage of charge for each Xiaomi headphone. For detailed information, it is recommended to use third-party apps from the App Store that are compatible with the MIUI protocol.
When connecting to a Windows or Linux computer or laptop, make sure that the Bluetooth adapter supports the Advanced Audio Distribution Profile (A2DP) profile. Without this profile, the computer can see the headphones as a low-quality headset (Headset mode) rather than a musical device.
For stable communication with the PC, it is recommended to keep the Bluetooth adapter at a distance of no more than 1-2 meters from the headphones, since the transmitter power in laptops is often lower than in modern smartphones. The presence of metal barriers or working USB 3.0 ports near the adapter can cause interference in the 2.4 GHz range.
