Xiaomi Redmi Airdots 2 wireless headphones have become a hit thanks to their affordable price and decent sound quality, but the process of initial tuning and pairing them often raises questions for beginners. Many users face difficulties in trying to make the right and left modules work in pairs rather than independently of each other, leading to confusion in the list of Bluetooth devices of the smartphone.
In this article, we will discuss all the steps in detail: from activation for the first time to forced resetting if standard methods do not work, you will learn the intricacies of the indicator, how to update the firmware through a special application and methods for eliminating common sound problems.
By following the steps, you can quickly activate your TWS-It is important to understand that the correct initial configuration guarantees stable operation of the gadget in the future.
Primary activation and extraction from the case
The process of getting to know the device starts from the moment you unpack, and there's an important nuance that's often overlooked: The new Redmi Airdots 2 comes with protective insulation stickers on the charging contacts located on the inside of each earphone. If you just open the case and try to get them out, the device may not turn on because there's no electrical contact with the dock.
Take both modules out of the charging case and carefully examine the bottom of each, carefully remove the transparent or blue film from the metal contacts, then return the headphones back to the charging case, and the indicators on the front should light up red, signaling the beginning of the energy storage process.
Once the devices are in the case for a few minutes, you can start the first switch on. Just remove them from the charging compartment, they must automatically go into pairing mode, as a quick flashing indicator will tell you. If this does not happen, it is possible that the battery is completely discharged, and you need to wait about 15-20 minutes.
💡
When first used, leave the headphones in the case for 30-40 minutes, even if the indicators show charge to calibrate the power controller.
Connection with Android and iOS devices
The smartphone is set up using the standard algorithm for Bluetooth accessories, but has its own characteristics depending on the operating system. Owners of Android smartphones, especially Xiaomi, Redmi and Poco models, are the luckiest, since MIUI and HyperOS have built-in support for pop-up windows for fast synchronization.
For iPhone and other Android devices, the process looks classic: you need to open the case lid without removing the headphones themselves, or pull them out to activate the search mode. In your phone's Bluetooth settings, a new device will appear, most often displayed as Redmi Airdots 2 or simply Airdots 2.
Click on the device name in the list of available gadgets and confirm pairing. In some cases, the system may request permission to access contacts or location — this is the standard procedure for widgets to work and determine battery power. Once the connection is successful, the voice assistant can say the phrase "Connected", confirming readiness.
☑️ Connection check
Synchronization of left and right headphone
One of the most common problems faced by budget owners TWS-The model is channel desynchronization, where the phone sees two devices with the same name or only one headphone is running, and this is due to a failure in the data protocol between the modules, and the task requires manual resetting to factory settings.
To restart the pairing process, first remove the device from the Bluetooth list on the phone by selecting the "Forget device" or "Unpair pairing" option. Then place both earbuds in the charging case and make sure they start charging (red lights are on). Without removing them from the case, press and hold the touchpads on both headphones simultaneously for 5-7 seconds.
The indicators have to flash red several times before they go out. That means the memory is clear. Now, get both of the headphones out at the same time -- they have to blink white quickly, find each other, and one of them will stop burning, going to standby mode while the other one continues to blink, waiting to be connected to the phone.
⚠️ Warning: If after resetting the headphones continue to be defined as two different devices, repeat the procedure, but this time hold the buttons longer until the end of the day. 15-20 seconds until the indicators flash three times red.

Status indication and management
Understanding LED color signaling is critical for comfortable use, as the Redmi Airdots 2 doesn’t have a screen or complex display.Red usually reports charging process or low energy levels, while white indicates active mode, device search or successful connection.
Playback and call management is done through touchpads located on the outside of each earpiece. The logic is simple: a single touch starts or pauses a track, a double tap on the right module often calls a voice assistant, and on the left one switches tracks back.
The table below shows the transcript of the main signals of the indicator, which will help you quickly diagnose the condition of the gadget without connecting to the phone.
| Color of indicator | Mode of work | User action |
|---|---|---|
| Red (burns) | Charging. | Leave it in the case. |
| Red (flashing) | Low charge. | Put it on charge. |
| White (blinks) | Interconnection mode | Search in Bluetooth. |
| White (burning) | Connected. | We can use it. |
Update to the firmware through Mi Earbuds Basic
While Xiaomi Redmi Airdots 2 is a budget model, they support software updates that can improve connection stability and sound quality.This will require the official Mi Earbuds Basic app (or Xiaomi Earbuds), which is available on Google Play and the App Store.
Once the app is installed and the headphones are connected, the program will automatically check the Firmware version. If a new version is available, a notification will appear on the screen. The update process takes a few minutes, and at this time it is extremely important not to close the application and keep the headphones next to the phone.
It’s worth noting that the update can fix interrupt bugs or improve the microphone, but if your headphones are stable, it doesn’t always make sense to force a firmware search, as the new version can change the way sensors work.
💡
Updating the firmware is the only way to fix the microphone software errors that cannot be fixed by resetting settings.
Resolving Sound and Microphone Problems
Users sometimes complain of quiet sound or poor hearing, and often the reason is not the breakdown, but the settings or contamination. Make sure that the Bluetooth settings on the smartphone do not activate the "Absolute volume" mode, which can conflict with the volume control on the headphones themselves.
Also worth checking is the speaker mesh — a protective film or earwax can significantly silence the sound, gently wipe them with a dry soft cloth or use a soft brush. To improve the microphone, try not to cover the bottom of the earphone with your fingers during a conversation, as there are noise-cancelling holes.
If the sound is monophonic or missing from one channel, try the full reset described above. In rare cases, the problem may be in the codec: go to Settings → For Android developers and try changing Bluetooth Audio Codec to SBC or AAC if the choice is available.
⚠️ Note: Do not use headphones in high humidity or rain, as the Airdots 2 model has spatter-only protection (IPX4), but not intended for submersion in water.
