Modern wireless headphones have become an essential accessory for smartphone owners, offering freedom of movement and no entangled wires. Xiaomi and its sub-brands such as Redmi and Poco are especially popular due to their excellent price-to-sound ratio. However, initial setup or re-connection of devices sometimes raise questions among users, especially if it comes to specific features or compatibility issues.
The connection process usually takes no more than a minute, but requires a certain sequence of actions to successfully synchronize Bluetooth protocols. In this article, we will discuss in detail all the stages of connection, from preparing gadgets to fine-tuning in the Android system, you will learn how to activate pairing mode, what codes may be required and what to do if the smartphone does not see the headset.
It is important to understand that the algorithms of operation may vary slightly depending on the version of the operating system and the accessory model. We will consider universal methods suitable for most devices, and also pay attention to the nuances of working with the Xiaomi Earbuds application.
Preparation of devices for pairing
Before you start any manipulation of wireless interfaces, you need to make sure that both devices are ready to work. Battery charge plays a critical role: if the headphones were in the case for a long time, their batteries could run out of charge. Place them in the charging case and connect it to the network for at least 15-20 minutes to ensure a stable start.
Also check the status of the Android smartphone itself. Make sure that the Bluetooth module is in good condition and is not in flight mode. Sometimes temporary system failures can prevent you from finding new devices, so it is not superfluous to restart the phone before starting the procedure.
⚠️ Note: If your headphones have previously been paired with another phone, they may automatically try to connect to it when turned on.For a successful connection to a new device, it is recommended to temporarily disable Bluetooth on an old gadget or remove the headphones from its list of forgotten devices.
Special attention should be paid to the cleanliness of the contacts. On the inside of the headphones and inside the case are metal contacts for charging. Pollution or oxides can interfere with normal charge, which will prevent the device from entering the pairing mode.
☑️ Checking before connection
Activation of the pairing mode on headphones
The most important step is to put the headset in visibility mode, unlike wired models, TWS-True Wireless Stereo headphones don’t always automatically become visible immediately after being removed from the case. The activation mechanism depends on the specific Xiaomi, Redmi or Poco model.
For most modern models, such as the Mi True Wireless Earbuds or Redmi Buds, it is necessary to remove both headphones from the charging case.If they do not start flashing indicators, press and hold the touch zones on both headphones simultaneously for 3-5 seconds.
Some models, such as Xiaomi FlipBuds or PRO-The versions have a physical button on the case of the charging case, in which case the headphones can not even be removed, just open the case cover and press the button on the back or bottom until the LED indicator on the case begins to pulse. This means that the device broadcasts a signal to search.
- 🔹 Classic method: Remove both headphones, they will automatically go to search mode (flashes the indicator).
- 🔹 Manual activation: Clutch the touchpads of both headphones simultaneously on 3-5 seconds before the indication appears.
- 🔹 Through the case: Open the cover of the charging case and press the pairing button on the case (if provided by the design).
- 🔹 Reset for: If conventional methods don't work, put the headphones in the case, press the button for 10 seconds before the red flash, then try again.
If you don't plan on plugging them in right now, it's best to put them back in the case or turn them off so you don't drain the battery. Visibility mode is usually active for 2-3 minutes, after which the device goes to sleep to save life.
Why can't the headphones be seen by the phone?
Search and Connect via Android Settings
Once the headset has gone into visibility, you need to perform actions on the smartphone side. Android interface may differ depending on the shell MIUI or HyperOS, but the logic of actions remains the same. Open the settings menu and find the section responsible for wireless connections.
In most cases, the path is as follows: go to Settings → Bluetooth. Make sure the activation slider is in the "On" position. The smartphone will automatically search for available devices within range. The list of gadgets found will be displayed at the bottom of the screen in the "Available devices" section.
Find the name of your model in the list. It can look like Xiaomi Earbuds Basic, Redmi Buds 3, or just as the model code. Click the name for initiation of the connection. The system can request confirmation of pairing or input. PIN-The standard code for most Xiaomi devices is 0000 or 1234, but modern models are often paired without asking for code thanks to the security protocol. SSP.
Once you've successfully connected, you'll hear voice confirmation in your headphones (usually the phrase "Connected" or a beep), and on your phone screen, status will change to "Connected." Now the audio stream will be transmitted wirelessly. If the sound didn't go automatically, check the output in the notification curtain or in the media settings.
Using the Xiaomi Earbuds app to customize
While the basic connection works right away, a dedicated app is recommended to unlock the full potential of Xiaomi accessories.The official Xiaomi Earbuds app (formerly known as Mi Earbuds) lets you control noise reduction, equalizer and update firmware. You can download it from Google Play or through scanning. QR-code-in.
Once you install the app and provide the necessary permissions (geolocation, Bluetooth, notifications), launch it. the app will automatically detect the connected headphones. If this does not happen, click the add device button and follow the instructions on the screen. In some cases, you may need to re-pair through the interface of the application itself to activate advanced functions.
The following important settings are available inside the application:
- 🎚️ Equalizer: Selection (preset) of sound profiles (bass, vocals, balance) or manual frequency setting.
- 🔇 Noise suppression (ANC): switching modes (active, transparent, off) to adapt to the environment.
- 🖱️ Touch control: reassigning actions to double or triple touch (track switching, calling an assistant).
- 🔋 Battery monitoring: accurately displaying the left and right headphone charge separately, which is not always available in the standard Android interface.
⚠️ Note: For the correct operation of the Xiaomi Earbuds application, you need to allow access to geolocation, even if you do not plan to use the headphone search features on the map (BLE) scanning.
Check the update section of the app regularly. Xiaomi engineers periodically release firmware updates that improve connection stability, microphone performance and noise reduction algorithms. The update process takes a few minutes, and at this time, it is better not to use the headphones and keep them near the phone.
💡
For more stable operation of the Xiaomi Earbuds app, add it to the battery exception list (Sun Run) so that the Android system does not close it in the background.This will provide a permanent widget with battery charge in the notification curtain.
Compatibility table and connection characteristics
Not all headphone models support the same set of features when connecting to different versions of Android. Below is a table showing the dependencies between the operating system versions and the available codecs or features for Xiaomi devices.
| Model headphones | Min version of Android | Support for aptX Adaptive | Application for setting | Sound delay (MS) |
|---|---|---|---|---|
| Redmi Buds 3 Pro | Android 6.0+ | Yes (with a compatible phone) | Xiaomi Earbuds | ~80-90 |
| Mi True Wireless 2S | Android 5.0+ | No (AAC/SBC only) | Mi Earbuds | ~120 |
| Xiaomi FlipBuds Pro | Android 8.0+ | Yes (LHDC 4.0) | Xiaomi Earbuds | ~60 (Game Mode) |
| Poco Buds Pro | Android 6.0+ | Yes. | Xiaomi Earbuds | ~90 |
| AirDots 3 | Android 5.0+ | No. | Not required | ~150 |
As you can see from the table, using advanced high-resolution codecs like LHDC or aptX Adaptive requires not only an appropriate accessory, but also a smartphone that supports these standards at the hardware level. If your phone does not support a particular codec, the connection will automatically switch to universal AAC or SBC, which will ensure work, but with less sound quality.
The game mode that reduces the latency of sound also depends on support from the phone. In the Xiaomi Earbuds app, you can force the low latency mode to be turned on, but its effectiveness will vary depending on the model of the smartphone processor and the Bluetooth version.
💡
The sound quality and the presence of advanced functions directly depends not only on the headphones, but also on the capabilities of the Bluetooth module of your smartphone.
Solution and resetting of settings
Even if you do the instructions correctly, you can have technical difficulties, and the most common problem is that the phone sees the headphones, but the connection doesn't happen, or the connection is constantly interrupted, and in such cases, the effective method is to completely reset the headphones to the factory.
To perform the reset, place both earbuds in the charge case. Make sure they're charged. Find the function button on the case (or use the touch zones if the button isn't there). Press the button and hold for about 10-15 seconds. The indicator should flash red several times before going out or catching white. This means the headphones' memory is cleared and they're ready for new pairing as new devices.
Other common problems and solutions:
- 📶 Quiet sound: Check to see if the Android developer's "Absolute Volume" settings are on, or try to turn it off. Also make sure the speaker safety nets aren't clogged with gray.
- 🔇 Only one headphone works: Reset (as described above), then remove the device from the Bluetooth list on the phone ("Forget the device") and pair again by delivering both headphones at the same time.
- ⚡ Fast discharge: Check if constant noise cancellation or game mode is activated if not necessary. Also update the firmware through the app.
If you reset and try to connect again, try connecting your headphones to another smartphone, which will help localize the problem: if the other phone is working, it's your Android settings. If not, the accessory or battery may be faulty.
⚠️ Note: When you reset your headphone settings, all previously saved pairs will be deleted. You will have to reconnect them to all devices with which they were previously paired.
