Modern smartphones line Xiaomi, Redmi and POCO equipped with advanced Bluetooth modules, which makes it easy to connect any periphery, including popular TWS-Headsets and full-size models. The pairing process often seems complicated only at first glance, but in an operating system. MIUI It's as automated as possible, but users often face nuances when the device is not visible in the list of available devices or the connection is constantly broken.
In this article, we will discuss in detail the algorithm of actions that will help you quickly activate the mating mode and adjust the quality sound. You will learn about the hidden functions of codecs, how to solve typical errors and the peculiarities of working with accessories of different brands on the devices of the Chinese giant.
Before we get into technical manipulation, itβs worth noting that the success of the operation depends not only on the phone, but also on the battery charge of the headset. Make sure your headphones have enough charge to enter detection mode. If the battery is completely dead, the device may not respond to touching or pinching buttons, which often confuses users about the health of the gadget.
Preparation of the headset for the coupling mode
The first and most important step is to put the audio device in visibility mode, and many users mistakenly believe that it is enough to simply turn on the headset, but for the first connection to a Xiaomi smartphone you need to activate a special search mode, without which the phone simply will not be able to βseeβ the new device on the air.
For most people. TWS-True Wireless Stereo models, such as AirPods, Galaxy Buds or Xiaomi Earbuds, have the following algorithm: place both headphones in a case, open the lid, and find a function button that can be located on the back, inside the speakers, or on the end of the case.
- π Press the button on the case on 3-5 seconds before the indicator flashes quickly.
- π§ If the button is not there, remove both headphones and simultaneously touch touch touch areas (or press mechanical buttons) on the headphone. 5-7 seconds.
- π‘ Watch for the LED: it should light up white or start blinking quickly, which signals readiness for (conjugation).
In the case of full-size models, such as the Sony WH-1000XM or JBL, it is usually required to press the on button or a separate Bluetooth button. The indication should change the blinking pattern from slow to frequent. If you previously connected these headphones to another phone, they can automatically try to connect to it, ignoring your Xiaomi, in which case it is better to temporarily turn off Bluetooth on the old device.

If the indicator is lit red or flashes red, first put the headphones on charging - in low-charge mode, the pairing mode is often blocked.
Bluetooth configuration in the MIUI and HyperOS interface
After the headset is ready, we move on to the smartphone settings. Xiaomi's shell interface may vary slightly depending on the Android version and regional firmware, but the logic remains the same. You need to get into the wireless module control center.
The quickest way is to lower the swipe notification curtain from top to bottom. Find the Bluetooth icon and click on it (not just turn it on, but click to go to the menu). If you use the old curtain style, the icon can be hidden in the optional button editing menu.
The alternative path through the system menu is as follows:
- Open the Settings app.
- Go to the Bluetooth section (in some versions it is inside the Connection and Sharing point).
- Activate the slider at the top of the screen if it is turned off.
Now, look at the "Available Devices" list. The smartphone will start scanning the ether. This process can take anywhere from 5 to 15 seconds. If your headset is properly placed in search mode, its name will appear on the list. Note that sometimes the device may appear under the model's code name rather than the marketing name.
βοΈ Checking before connection
Connection process and access confirmation
When your headset name appears on the list of available devices on the Xiaomi screen, click on it. The system initiates the handshake procedure, during which the encryption keys are exchanged, at which point a request for confirmation of pairing with the code or simply a notification βConnectedβ may appear on the screen.
In some cases, especially when connecting car systems or specific headsets, input may be required. PIN-The standard combinations are most often 0000 or 1234, but this information is always in the instructions for a particular accessory. TWS-Headphones usually do not require code entry, relying on a secure pairing protocol.
Once the connection is successful, the device will change its status to Connected (or Connected: Music, Calls) and the sound from the phone will be broadcast to the headphones. If that doesn't happen, check the output settings: sometimes the phone will connect but will continue to play music through the speaker.
β οΈ Warning: If you have a message that says "Unconnected" or "Pairing error" when you connect, don't panic. Often it's a temporary protocol failure. Try turning off and on Bluetooth on your phone, and then try again.
An important aspect is allowing access to contacts and call logs. When you first connect, Xiaomi will ask permission to sync contacts. If you plan to use the headset for conversations, you need to click Allow. Otherwise, you will hear the sound of the call, but you will not be able to see the name Caller ID.
Compatibility table and sound codecs
The sound quality depends on the supported codecs. Xiaomi mid- and high-end smartphones support modern compression standards such as aptX, aptX HD and LDAC. However, the headset itself must also support these formats, otherwise the sound will be broadcast in the basic quality of SBC.
Below is a table showing the influence of the codec on audio stream parameters when using a compatible phone-earphone pair:
| Codec | Bitrate (example) | Delay (Latency) | Sound quality |
|---|---|---|---|
| SBC | 328 kbps | High (220 ms) | Basic |
| ACC | 256 kbps | Medium (150 ms) | Good (iOS standard) |
| aptX | 352 kbps | Low (70 ms) | High. |
| LDAC | 990 kbps | Variable | Hi-Res (maximum) |
You can use an engineering menu or special applications to check which codec is currently in use, but standard MIUI tools often hide this information from the average user, but the system automatically selects the best available option.

Advanced sound settings and equalizer
Once successfully connected, it makes sense to customize the sound to your preferences, with Xiaomi phones being run by the built-in Mi Sound or Dirac Audio module (in flagship models), which allows you to adjust the frequency characteristics of the connected headphones.
To access the settings, go to Settings β Sound and Vibration β Sound Quality and Effects (the path may vary). Here you will find a graphical equalizer. If you use headphones with a focus on bass, you can slightly lower the low frequencies to remove the humminess.
- π΅ Choose the preset ready: Pop, Rock, Jazz or Classic for quick setup.
- π Enable the βMi Sound Enhancerβ function for virtual stereo expansion.
- π§ Adjust the balance of the left and right channel if you hear a skewed sound.
You also need to pay attention to the Absolute Volume feature, which sometimes turns the volume of the phone to the maximum, and the headphones are silent, or vice versa. Switching this setting to the developer menu or in special Bluetooth settings can synchronize volume sliders.
β οΈ Warning: Donβt overuse the bass boost through the equalizer at maximum volume.This can lead to the wheezing of speakers in budget models of headphones and even to their mechanical damage (retraction of the coil).
Problem Solving: Headphones are not connected or not working
Despite standardizing protocols, Xiaomi users have been plagued by problems, with a crowded list of paired devices being a common cause, and the phone may try to connect to an old garnitta that is out of reach, blocking the search for a new one.
To solve this problem, go to the Bluetooth menu, find old or unnecessary gadgets in the My Devices list, click on the gear icon next to them and select Cancel pairing or Forget device. After cleaning the list, repeat the search.
Another common problem is the desynchronization of the left and right headphones in the TWS-If the sound comes from only one ear or the channels are mixed, you need to reset the headphones themselves, usually by clamping the sensors on both earphones simultaneously on the headphones. 10-20 seconds until the indicators flash a specific color (often red).
If nothing works, try the following algorithm:
- Turn off Bluetooth on your phone.
- Remove the headphone profile from the phoneβs memory.
- Reboot your Xiaomi smartphone.
- Reset the headphones to factory settings.
- Repeat the process of pairing from the beginning.

In 90% of cases, the problem is solved by completely cleaning the list of conjugated devices on the phone and restarting the smartphone, since the Bluetooth module could hang in the background.
