Modern wireless headphones from the Xiaomi brand and the sub-brand Redmi have gained popularity due to the affordable price and stable operation. However, the process of initial pairing or reconnecting to a new device sometimes raises questions for users. The correct sequence of actions ensures not only an instant start of listening to music, but also a stable signal without breaks in the future.
In this article, we will analyze in detail the algorithms for connecting different models of headsets, from classic neckband versions to fully wireless ones. TWS-You'll learn about the intricacies of the Bluetooth protocol in the shell. MIUI and HyperOS, and get instructions on how to solve typical communication problems.
Before we move on to specific models, it's important to understand the general principle of wireless data technology: pairing is the process where two devices exchange encryption keys to create a secure communication channel, and without successfully passing this procedure, the audio stream will not be transmitted to the speakers.
Preparation for pairing and activation of the search mode
The first step should always be to prepare the equipment. Make sure your Redmi Buds headphone or wired headset with a Bluetooth adapter is charged at least 20-30%. Low battery power can cause the device to not go into detection mode or to function unstable immediately after you connect.
To enter the pairing mode, you usually need to press the function button on the case body or neck bow. The indicator must start flashing blue (sometimes in combination with white or red) This is a signal that the Bluetooth module has moved to active standby mode for command from the smartphone.
If the indicator doesn’t light up, check the charging contacts in the case or try replacing the cable. In some models, such as the Redmi AirDots, the headphones must first be removed from the case to activate, and only then clamp the touch panels to reset or go into search mode.
⚠️ Note: Do not hold the button to switch to pairing mode for too long (more) 15-20 seconds) without needing it, as this may trigger a full reset to factory settings, which will require the device to be re-registered in the phone.
In parallel with the preparation of the headset, you need to activate the corresponding module on the smartphone. Go to the system settings and make sure that the Bluetooth slider is in the "On" position. In the new versions of MIUI and HyperOS, this option is controlled in the upper curtain of notifications for quick access.
💡
If the headphones have previously been connected to another phone, they may automatically try to connect to it. temporarily turn off Bluetooth on the old device so that the Redmi headphones start looking for your current smartphone.
Connection algorithm TWS-Models (Redmi Buds, AirDots)
Fully wireless headphones require a more careful approach, as they synchronize three devices: left channel, right channel and smartphone, first to ensure communication between the ears themselves, and then connect them to the phone.
Remove both headphones from the charge case. In most cases, they will automatically go into pairing mode if they are turned on for the first time. If the device has been used before, you may need to manually start. On some Redmi Buds 3 or 4 Pro models, you just need to open the case cover next to the unlocked Xiaomi phone.
A pop-up window with animation and model name should appear on the smartphone screen. Press the "Plug" button. The system will set up the necessary profiles for Calls and Media (music). If the automatic window does not appear, find the device in the list of available networks manually.
- 🎧 Remove the headphones from the case and wait for the flashing of indicators.
- 📱 Open the Bluetooth menu on your smartphone and start searching for new devices.
- 🔗 Select your model name (e.g. Redmi Buds 3 Pro) from the list.
- ✅ Confirm the pairing request if it appears on the lock screen.
Special attention should be paid to the Redmi AirDots (first generation), which often require manual channel synchronization. If only one earphone is playing, you need to reset their settings by clamping the touchpads on both devices simultaneously for 5-7 seconds before a red flash.

Connection of neck and overhead headsets
The Redmi Neckband series necksets or Mi Headphones overheads are connected in a similar scenario, but have their own controls, and the power button in these models is often combined with the pairing function.
To activate the search mode, hold the switch off for about 5-7 seconds. The indicator should start flashing blue quickly. This means that the device is visible to all surrounding gadgets within a radius of 10 meters.
Unlike in the TWS-models, there is no risk of desynchronization of the left and right channel, as they are physically connected. However, the sound quality may depend on the version of the codec"LDAC/AAC") The optimal value for your model is selected.
When you connect to a PC or TV with an Android TV shell, the algorithm remains the same, and the main thing is to make sure that the operating system does not block new connections for security reasons or energy savings.
| Model headphones | Action for the coupling regime | Indication | Feature |
|---|---|---|---|
| Redmi Buds 3 / 4 | Open the case / Press the case button | White flashing | Auto-Pairing with Xiaomi |
| Redmi AirDots | Hold sensors down (5 seconds) | Red flashing | We need channel synchronization. |
| Redmi Neckband | Hold the power button | Blue flashing | Voice menu |
| Mi Headphones | Bluetooth button / Power button | Blue-red | Hi-Res support |
Customization of sound and additional functions in the application
After a successful connection, it is recommended to install the branded Xiaomi Earbuds app (or use the built-in functionality in MIUI), which allows you not only to check the battery power of each channel, but also to adjust the equalizer to your ear.
In the app menu, you'll find noise reduction settings (ANCs). For Pro-level models, it's important to choose the right mode: "Transport," "Office" or "Maximum." The wrong mode choice can create a "pressure" effect on your ears or miss too much external noise.
Firmware updates are also available here. Regular updates to firmware headphones are critical to fix connection bugs and improve microphone stability. Don't ignore notifications of new software versions that appear in the app.
Users can reassign actions when touching touchpads, such as double taps can trigger tracks and triple taps can trigger a voice assistant, and flexible customization makes it as comfortable as possible for everyday tasks.
⚠️ Warning: When setting up noise reduction in windy weather, a strong whistle may occur. In such situations, the application should be automatically or manually switched to Transparency or Shutdown mode".
Problem Solving: Headphones are not visible or connected
If your smartphone can't see the headphones, the first thing you do is try to "forget" the device. Go to the list of paired devices, click on the gear or the information icon next to the headphone name, and select "Delete" or "Forget this device." After that, repeat the pairing procedure from scratch.
A common problem is overflowing the Bluetooth memory list on your phone. If you have more than 10-15 old devices saved, the new gadget may simply not be added.
Another reason is Bluetooth version conflict. Although the protocol is backward compatible, sometimes older headphones (Bluetooth 4.0) can not work properly with the latest smartphones (Bluetooth 5.3) without updating the phone's firmware. Check for system updates in the Settings → About Phone → MIUI version.
- 🔄 Reboot your smartphone and headphones (full shutdown cycle).
- 🗑️ Remove the headphone profile from the phone’s Bluetooth memory.
- 🔋 Charge the case and headphones to 100%.
- 📶 Reset your headphones to factory settings (Hard Reset).
In rare cases, radio interference is the problem. If you're near a powerful Wi-Fi source (router) or microwave, try to step away by 2-3 meters. 2.4 GHz protocols can conflict, causing delays or connection breaks.

Optimizing Bluetooth for a stable signal
For owners of Xiaomi and Redmi devices, the Quick Connect feature is available. It allows you to open a case next to your phone and instantly see the charge status on the lock screen without going to the settings menu. Make sure that geolocation (GPS) is enabled, since in Android, Bluetooth search is often tied to location services.
Energy saving is an important aspect. Aggressive battery settings can "kill" the Bluetooth background service process, causing the music to stop when the screen goes out. Go to Settings → Applications → All apps → Bluetooth and allow auto-start and work in the background.
Use high-quality codecs if your smartphone and headphones support them. AAC provides better quality on iOS and Android, while aptX and LDAC are preferred for high-end Android devices. You can switch the codec from the developer menu or in the audio settings.
💡
Connection stability is 90% dependent on the cleanliness of the paired device list and the relevance of the headphone firmware, and regular Bluetooth list hygiene prevents most errors.
