Modern wireless headphones have become an indispensable accessory for an active lifestyle, but their initial setup often raises questions among users. Xiaomi’s Redmi AirDots 2 model has an excellent price-performance ratio, but the process of synchronizing with a smartphone has its nuances. Understanding the principles of Bluetooth protocol will help you avoid common mistakes during the first launch.
In this article, we will discuss how to pair devices correctly so that sound is transmitted without delays and breaks. You do not need to be a technician to set up an audio gadget in a few minutes. We will look at the features of working with the Android operating system, and also touch on the aspects of connecting to the iPhone.
Proper radio channel setup ensures stable connection up to 10 meters away.If you've just unpacked the box or experienced connection problems after upgrading, follow our guidelines.The right approach ensures you can enjoy your favorite music or talk on the phone without technical glitches.
Redmi AirDots 2 Prepared for First Included
Before looking for a device in the list of available networks, make sure the headphones are ready to go. Charge the case and the liners themselves for at least 30-60 minutes using a complete Micro-USB cable. The indicators inside the case should light up red during charging and go out or light up white when fully charged.
It's important to remove both earbuds from the charger at the same time, and that's when they automatically go into pairing mode, as evidenced by the flashing lights, and if you pull out just one earbud, it may not go into search mode, as the system is waiting for the second part of the headset to appear.
💡
Keep the charging case closed while charging to avoid overheating and ensure the contacts on the bottom of the headphones are in proper contact.
Make sure your smartphone has a wireless module on. Go to Settings → Bluetooth and activate the slider. Now the phone will start scanning the space for available devices, and in a few seconds you will see the name Redmi AirDots 2 on the list.
Step-by-step instructions for connecting to Android
The process of syncing with Android devices is the most common use case: Open the Quick Settings menu or navigate to the Bluetooth section through the main Settings menu. Make sure your phone is visible to other devices, although this is not always strictly necessary for connectivity, but simplifies diagnosis.
- 🔍 Click on the Redmi AirDots 2 name in the list of available devices to start pairing.
- 🎧 Wait for the sound signal in the headphones, confirming the successful connection.
- 📱 Check the connection status in the status bar where the headphone battery icon should appear.
Once the connection is successful, the system can request permission to access contacts and call logs, so that you can see the name of the caller and control through buttons on the case, and if you refuse access, the headphones will only work as a headset for output.
☑️ Connection check
In some MIUI shells, additional confirmation may be required. If the connection is not established on the first attempt, try removing the device from the saved list and repeating the procedure. Often, simply turning off and turning on the Bluetooth module on the smartphone helps.
Features of pairing with iPhone (iOS)
Apple owners can also use these headphones, although the functionality can be slightly limited compared to Android.The connection process is almost identical: remove the headphones from the case and go to Settings → Bluetooth on your iPhone.
Note that iOS won’t display the exact percentage of charge of each headphone in the widget, as it does with the original AirPods. However, the charge level of the main device is often displayed in the Battery widget or in the control center.
Why is the auto-pause on the iPhone not working?
If you've previously connected your headphones to another phone, they might try to connect to it automatically, in which case you'll need to click "Forget this device" on your iPhone if it's on the list, and pair it again. Connectivity on iOS is usually high, but depends on the version of the operating system.
Mono mode and channel separation
One of the great things about Redmi AirDots 2 is that you can only use one headphone, which is convenient for calling or when you need to hear the environment, and to activate this mode, just remove one headphone from the case, leave the other one inside, or touch the touch zone on one of them if they're already removed.
In monophone mode, the second earpiece acts as a signal transmitter from the phone, which means that the battery consumption on the active earphone will be higher, and there may be a slight increase in the delay of sound when watching video, as the signal goes a double way: phone → earphone 1 → earphone 2 (if it is on).
| Mode of work | Indication | Energy consumption | Features |
|---|---|---|---|
| Stereo (both) | Blinking synchronously | Standard. | Surrounding sound |
| Mono (left) | It's burning all the time. | High-pitched | I hear the surroundings. |
| Mono (right) | It's burning all the time. | High-pitched | Main microphone |
| Waiting. | Rare flashing | Minimum | Ready to connect. |
To return to stereo, you just need to remove the active earphone in the case and re-extract both, and the system automatically reconnects in True Wireless Stereo mode. If that doesn't happen, you may need to reset, which we'll talk about later.
Control of touch buttons
Playback and call control is done through touch zones located on the outside of the case. Pressing should be short and clear. Long-term pressing is usually used to activate the voice assistant or answer an incoming call, while single or double touch regulates the tracks.
The configuration of the buttons may vary depending on the firmware, but the standard command set looks like this:
- 🎵 One touch: Play/Pause (playback/pause).
- ⏭ Double touch: Next track.
- 📞 Long press (2 seconds): Accept a call / End the call / Activate the assistant.
Use a controller on your smartphone to change the sound level. Some users have noted that triple tapping can activate the previous track, but this depends on the specific version of firmware.
Resetting settings and troubleshooting problems
If the headphones are no longer connected to each other or the phone can't see them, you need to perform a complete reset. This procedure returns the device to factory settings and clears the memory of previous pairings. First, remove the device from the Bluetooth list on the phone ("Forget the device").
Then place both earbuds in the case. Press and hold the touch zones on both earbuds simultaneously for 20 seconds until the indicators flash red several times. After that, remove them, and they should go into fast blink mode, ready for a new connection.
⚠️ Warning: Keep your headphones in your hands and not in your case when resetting, unless the instructions for your specific revision require otherwise. Make sure they are at least 20% charged or the process may be interrupted.
A common problem is to desynchronize the channels when the sound comes from only one earpiece, which helps to repeat the reset procedure, and also check if the headphones are connected to another device nearby that can intercept the signal.

Hard Reset solves 90% of software problems with connecting and dissynchronizing channels in Redmi AirDots headphones.
Technical specifications and compatibility
Redmi AirDots 2 is based on Bluetooth 5.0, which provides energy efficiency and stable signal. SBC codec is the main audio transmission, which guarantees compatibility with any modern smartphone, tablet or laptop.
The IPX4 moisture protection allows the headset to be used during sports training or in light weather, but diving or exposure to a high jet is strictly prohibited. Headphone drivers are tuned to a balanced sound with an emphasis on medium frequencies.
⚠️ Note: Do not use headphones immediately after leaving a cold room to a warm room without acclimatization, condensation inside can damage electronics.
The running time on a single charge is about 4 hours of continuous listening, and the case allows you to extend this time to 12-14 hours, the charging speed of the case is about 1.5 hours, which is the average for this price segment.
