Modern wireless headphones, such as Xiaomi Redmi AirDots, have become an integral accessory for owners of smartphones based on Android. The initial setup process usually takes a few minutes, but beginners often have difficulties with pairing mode or synchronizing the left and right channels. Understanding the logic of operation TWS headset (True Wireless Stereo) will help you avoid common mistakes when connecting.
In this article we will analyze in detail the algorithm of actions for successfully connecting your phone and headphones. You will learn how to correctly enter the device into visibilitymode, what to do if the phone does not see the headset, and how to force a factory reset. This knowledge will be useful not only during the first purchase, but also in situations where the connection is suddenly interrupted.
Please note that the procedure may vary slightly depending on the version of your operating system Android and the specific model of headphones (regular AirDots, S or Pro). However, the basic principle of interaction via the protocol Bluetooth remains the same for all devices in the ecosystem.
Preparing the headphones for the first use
Before trying to find a device in the list of available connections, you need to make sure that the headphones are charged and ready to use. Often users skip this step when trying to connect discharged cases, which leads to an initialization error. Remove both headphones from the charging case at the same time.
After removal, the indicators on the cases should light up red, signaling the start of operation. At this moment, an automatic search for each other occurs to create a stereo pair. If you take them out one at a time at a long interval, synchronization between the left and right channels may not occur correctly.
⚠️ Attention: Do not put the headphones back into the case immediately after removing them. Give them 5-10 seconds to establish communication with each other before activating Bluetooth on your phone.
Make sure that the protective films from the contact pads on the headphones themselves are removed (this is true for new devices). Lack of contact with the charging pins in the case may result in the indicator not lighting up when removed, and the device will be considered turned off.
If the indicators do not light up when removing, try pressing the headphones firmly against the contacts inside the case for a few seconds to activate charging, and then take them out again.
Activating pairing mode on smartphone
Now let's move on to the settings of your mobile device. To get started, you need to activate the wireless communication module in the system Android. Open the notification curtain by swiping from top to bottom and find the icon Bluetooth.
Click on the icon to make it active, or go to the menu Settings → Connected devices → Bluetooth. In this section, the system will begin automatically searching for all available devices within range. Make sure that geolocation is enabled, as in new versions of Android this is a requirement to search for BLE devices.
Your model name should appear in the list of available devices, for example Redmi AirDots or AirDots_R. It is important to understand that for stereo sound you need to select only one device from the list. If you see two identical names, this is a sign that the channels are out of sync.
- 📱 Open quick settings with the notification shade.
- 🔍 Press and hold the Bluetooth icon to go to the full menu.
- 🔄 Refresh the list of devices by swiping down if the desired name does not appear immediately.
The connection process and channel synchronization
When you click on the device name in the list, the phone will send a pairing request. At this stage, you may need to confirm the passcode, although most headsets Xiaomi use a standard code or connect automatically without entering numbers.
Successful connection is confirmed by a voice message inside the headphones in English or Chinese (“Connected” or “Yi Lian”). At the same time, the indicators on the headphones should go out or start flashing at different intervals, indicating an active connection with the phone.
☑️ Checking successful connection
If the sound is played only from one earphone, it means that a stereo pair has not been formed. In this case, the phone is connected to only one of the modules (usually the right one, which is the master). You need to turn off Bluetooth on your phone, put the headphones in the case and repeat the extraction procedure synchronously.
⚠️ Attention: If two identical names are displayed in the list of devices (for example, two "AirDots_R"), delete both profiles from the phone's memory through the "Forget device" menu before trying to connect again.
Compatibility table and connection characteristics
Important for correct operation take into account the Bluetooth protocol version supported by your smartphone. Although the standard is backward compatible, using older versions may result in audio delays or an unstable connection.
| Bluetooth version | Connection stability | Range | Power consumption |
|---|---|---|---|
| 4.2 and below | Low (breaks are possible) | Up to 5 meters | High |
| 5.0 | Stable | Up to 10 meters | Optimal |
| 5.1 and higher | High (low latency) | Up to 15 meters | Low |
| 5.3 (latest) | Maximum | Up to 20 meters | Minimum |
Use Bluetooth 5.0 and above guarantees better synchronization of the audio and video stream. If your phone only supports older standards, you may notice lip synchronization when watching videos on social networks.
Why is the Bluetooth version important?
Newer versions of the protocol use improved signal encoding algorithms, which allows you to transmit more data with less radiation power. This is critical for TWS headphones, where every milliwatt of energy counts.
Resetting settings and solving connection problems
Sometimes a software glitch causes the headphones to stop responding to commands or not see each other. In such cases, a procedure is required Hard Reset. This process returns the device to factory settings and clears the memory of previous pairings.
To perform a reset, place both earbuds in the charging case. Make sure they start charging (the lights are red). Then press and hold the touchpads on both headphones simultaneously for 20-30 seconds.
Reset sequence:1. Insert into case.
2. Press the sensors for 20 seconds.
3. Wait for the indicator to flash 3 times.
4. Remove and re-pair.
The indicators should flash red three times, indicating a successful reset. After that, you need to take them out again, wait for them to synchronize with each other, and only then look for them in your phone. In this case, it is advisable to delete old connection profiles on the phone.
⚠️ Attention: Android settings interfaces may differ depending on the manufacturer’s shell (MIUI, OneUI, ColorOS). Menu items may be named differently, but the logic of actions remains the same.
Operation optimization and additional settings
After successful connection, you can customize the behavior of the headphones to suit your needs. Some models allow control via a voice assistant or change touch functions. To expand the functionality, it is recommended to install a proprietary application Xiaomi Earbuds.
The application allows you to update firmware headphones, which often corrects connection errors and improves sound quality. There you can also turn off voice prompts if they are annoying, or reassign actions to double and triple taps.
- 🎧 Update the firmware through the stability application.
- 🔇 Disable voice notifications in settings.
- ⚡ Check the charge level of each earphone separately.
Regular firmware updates via the official application are the best way to eliminate micro-sound delays and problems with automatic shutdown.
Frequently asked questions (FAQ)
Why does the phone see only one earphone?
This means that the headphones are not synchronized with each other in a stereo pair. Perform a full reset (Hard Reset) while holding the sensors in the case, and redo the pairing procedure, taking out both devices at the same time.
How to connect Redmi AirDots to two phones at once?
Models of the AirDots series do not support Multipoint technology for simultaneous connection to two sources. You need to turn off Bluetooth on the first device so that the headphones can connect to the second.
The headphones run out quickly, what is the reason?
Check the contact pads in the case and on the headphones. If they are dirty, charging may not proceed. Wipe the contacts with a dry cotton swab. Also, the battery may wear out after 2-3 years of active use.
Can only one headphone be used?
Yes, you can use any of the headphones in mono mode. To do this, simply remove one of them from the case and leave the second one inside or turn it off. The phone will connect to the active module.
