Modern Xiaomi and Redmi smartphones offer users not only powerful hardware, but also user-friendly interfaces to work with the peripherals. Connecting wireless headphones has become the standard, allowing you to enjoy music or talk without unnecessary wires. However, despite the automation of processes, users often face the nuances when the device is not in place or the connection is cut off.
In this article, we will discuss in detail the algorithm of actions for successfully pairing a Bluetooth headset with a MIUI or HyperOS shell. You will learn how to correctly translate accessories into search mode, where to look for hidden codec settings and what to do if your phone “does not see” a new device.
Preparation of headphones and smartphone for pairing
Before starting the procedure, make sure that both devices are ready to go. On Xiaomi, Redmi or POCO smartphones, the Bluetooth module is usually turned on by default, but check will not be unnecessary.
The most critical aspect is the introduction of the headphones themselves into visibility mode, and many users mistakenly believe that simply turning on the device is enough. It's not: if the headphones were previously paired with another phone, they can automatically connect to it, ignoring your new Xiaomi.
⚠️ Note: If your headphones have been used with another phone before, be sure to turn off Bluetooth on your old device or remove the headphones from its paired list, otherwise they will try to connect to it automatically.
To go into search mode on most models TWS-Headphones need to press the touchpad or physical button for 5-7 seconds before the flashing indicator (usually white or red-blue) appears.
💡
For a stable connection, make sure that the headphones are charged at least 20-30%, since at low charge, some models go into energy-saving mode and become invisible.
Step-by-step connection instruction via MIUI settings
The MIUI shell interface may vary slightly from one version to another, but the logic of the Bluetooth module remains the same. First step, open the Settings app on the home screen or in the notification curtain.
In the menu that opens, look for the Bluetooth section, which can be located in the top of the quick action list or inside the Connect and Sharing category. Click the switch to activate the module if it is turned off.
The system will automatically start scanning the available devices, and the name of your headset should appear on the Available Devices list, often matching a model like AirDots, Haylou, or the manufacturer's brand.
☑️ Connection algorithm
Click on the device name. You may see a request for confirmation of pairing or input on the screen. PIN-After a successful link, the status will change to "Connected", and next to the icon of the battery level will appear.
Use of quick menus and widgets
For those who value time, there is a faster way to activate search: In Xiaomi smartphones, just swipe down from the top right corner of the screen to open the control center.
Press your finger on the Bluetooth icon (or press and hold) to go to the extended menu. Here you will see a list of newly connected devices. If the desired headset is not in the list of My devices, the system will offer the button “Other devices” or automatically start a search.
The advantage of this method is that it allows you to quickly switch between previously saved gadgets without deep immersion in the settings, which is especially convenient when using multiple pairs of headphones for different purposes.
⚠️ Warning: Do not try to connect to the device if the indicator on the headphones is on or off – they should be sure to flash, signaling a detection mode.
In some versions of the firmware when bringing a charging case TWS-The headphones to the unlocked smartphone Xiaomi pops up automatic pairing window. This is a proprietary feature that works with devices of the Mi ecosystem.
Customization of sound quality and codecs
Once the connection is successful, it makes sense to check additional audio output options. Xiaomi supports various compression codecs that affect the quality of audio transmission. Standard is the SBC codec, but for Hi-Res audio, it is better to use aptX or LDAC.
To check for supported codecs, go to the Bluetooth menu, click on the gear next to the name of the connected headphones. If the device supports high-quality transmission, relevant information may be displayed here.
For advanced users, the hidden developer section is available, and to activate it, you need to quickly click on the build number 7 times in the About Phone section» → «For developers, you can find the item “Bluetooth audio codec».
Should I turn on LDAC?
You can also turn off the "Absolute Volume Level" feature, which is useful if the volume of the headphones and phone is out of sync (for example, on the phone maximum, but in the headphones quiet).
Table of popular Bluetooth codecs
Understanding the differences between codecs will help you choose the optimal listening mode. Below is a comparison of the main standards supported by Xiaomi smartphones.
| Codec | Sound quality | Delay (MS) | Compatibility |
|---|---|---|---|
| SBC | Basic | 200-250 | Universal. |
| aptX | High (CD) | ~120 | Android, Qualcomm |
| aptX HD | Hi-Res (24-bit) | ~120 | Android flagships |
| LDAC | Highest. | 200-250 | Android 8.0+ |
Codec selection is often automatic depending on the capabilities of both devices, but you can force the developer menu to set a priority format for data transfer.
💡
Low latency is critical for gaming, so aptX Low Latency codecs or game modes in Bluetooth settings are preferable to LDAC.
Solution: Headphones not connected or the sound interrupted
If automatic pairing fails, try resetting your network settings. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks, and Bluetooth. This action will delete all stored networks and devices, but often resolves software conflicts.
Another common cause of problems is a crowded Bluetooth cache. In the application menu, find the system process "Bluetooth", go to "Memory" and click "Clean". After that, the phone needs to restart.
If the sound is interrupted or only one headphone (left or right) is working, perform a full reset. TWS-This is usually done by holding the sensors on both headphones inside the case or outside for a long time until the indicators flash a certain color (see manual for a particular model).
⚠️ Warning: When you reset your headphones, they may be removed from the list of paired devices on your phone, and you will have to re-search and connect as if to a new device.
It’s also worth checking if the Mono-Audio feature is activated in the special features section, which brings the stereo signal into one channel, which sometimes causes conflicts with Bluetooth drivers.
