Modern smartphones of the Xiaomi Redmi i Poco line offer users advanced multimedia capabilities, but the first thing to do after purchase is to set up wireless audio transmission. Connecting a headset via cable is becoming a thing of the past, giving way to the convenience of technology Bluetooth. However, the pairing process on the shell MIUI or a new one HyperOS has its own nuances that can confuse a beginner.
In this guide, we will analyze in detail the algorithm of actions for a stable connection, consider hidden codec settings and solve typical problems when the phone does not see the device. Correct settings at the start will save you nerves in the future and provide high-quality sound when listening to music or talking.
Before moving on to the menu settings, make sure that your headphones are charged and in ready-to-pair mode. Often, users try to connect a device that is already paired with another gadget, which leads to detection errors.
Preparing the headphones for pairing mode
The most critical stage is putting the headset into discovery mode. Many users simply turn on the headphones, but this is not enough to connect to a new phone for the first time. The device must actively broadcast the search signal.
For most models, including popular AirDots or Redmi Buds, you need to remove both headphones from the case and hold the touch panels (or physical buttons) for 3-5 seconds. The light will flash white or red to indicate it's ready.
If you have a full-size headset, the procedure may vary. Typically, you need to hold down the power button or a special button with a Bluetooth image until the indicator flashes quickly. Without active flashing of the indicator, the Redmi phone will not be able to detect the device in the list of available ones.
Make sure that there are no other active devices nearby that the headphones were previously connected to. They can automatically intercept the connection, and the Xiaomi phone simply will not see the headset in search mode.
If the indicator flashes slowly or is constantly on, it means the headphones are not in pairing mode. Try turning them off and repeating the procedure of holding the button longer.
Search and connect in the MIUI and HyperOS settings
The Xiaomi shell interface may change from version to version, but the logic of the communication module remains the same. You need to get to the wireless interface control center.
Open the application Settings and find the section Bluetooth. In new firmware versions, this item is often moved to the top of the menu or combined with the Connection and sharingsection. Make sure that the activation slider is switched to the position On.
The phone will automatically start scanning the airwaves. This process may take from 5 to 15 seconds. The name of your headset should appear in the list. Click on it to initiate the pairing procedure. Available devices The name of your headset should appear. Click on it to initiate the pairing procedure.
- 📱 Make sure that the phone screen is unlocked during the search, as scanning may pause in sleep mode to save energy.
- 🔋 Check whether it is turned on GPS (Geolocation) —in some versions Android this requirement is mandatory for the Bluetooth scanner to work.
- 🔄 If the device does not appear, click on the three dots in the corner of the screen and select
Updateto search again.
After clicking on the device name, the system will ask you to confirm pairing. In rare cases, you may need to enter a PIN code; the standard value is usually 0000 or 1234, but modern models do without this step.
☑️ Successful connection algorithm
Setting the sound quality and codecs
After a successful connection, standard settings may not reveal the potential of your audio system. The Xiaomi shell allows you to flexibly control sound transmission parameters, which is especially important for music lovers.
Go to the Bluetooth menu, click on the gear next to the name of the connected headphones. Here you will find the switch HD Audio. Activating this option allows you to use advanced codecs, such as aptX, aptX HD or LDAC, if they are supported by both devices.
The item Auto-connectis also available in this menu. If you disable it, the headphones will not try to connect to your phone automatically when turned on, which is useful if you use one headset with several gadgets.
⚠️ Attention: Enabling HD Audio mode may increase the battery consumption of both the smartphone and the headphones, as well as cause slight audio delays in games.
Hidden menus are available for users involved in mobile development or fine-tuning. You can force a codec selection through the engineering menu, but this should only be done if you have technical knowledge.
How to enter the engineering menu to check codecs
Enter the code in your phone ##6484## to enter the CIT menu or use the Activity Launcher application to search for Bluetooth system activities, but be careful when changing system parameters.
Problem solving: the phone does not see the headphones
The situation when Xiaomi Redmi ignores a wireless headset is not uncommon. Most often, the reason lies not in a breakdown, but in a software conflict or service cache failure.
First of all, try rebooting both devices. This is a simple but effective tip that clears temporary errors in the Bluetooth stack. If this does not help, go to deeper settings.
Go to Settings → Applications → All applications. Click on the three dots in the corner and select Show system processes. Find the process Bluetooth or Bluetooth servicesin the list, go into it and click Clear → Clear cache. Do not delete data unless you want to reset all saved pairs.
| Problem symptom | Possible cause | Solution method |
|---|---|---|
| Headphones are not visible in the list | Pairing mode is not active | Hold the button on the headphones until it flashes quickly |
| The connection is reset immediately | Profile conflict or low charge | Charge the devices, delete the pair and create again |
| The sound is interrupted or wheezing | Wi-Fi interference or air overload | Turn off Wi-Fi or move away from the router |
| No sound in the media player | Incorrect connection profile | In the Bluetooth settings, check the "Media Audio" checkbox |
If the problem persists, check if the mode Do not disturb or Silent modeis enabled, although usually they do not affect the actual connection itself, only blocking audio output.
Features of working with multiple devices
Modern Xiaomi smartphones support connecting to several audio devices simultaneously, but with limitations. You can have a list of dozens of saved gadgets in your memory, but only certain combinations can be active.
The Dual Audio function (dual audio) allows you to output sound to two pairs of headphones at once. This is convenient for watching movies with a friend. To activate this, connect the first headset, then in the same Bluetooth menu, find and connect the second.
However, it is worth remembering the channel bandwidth. Simultaneous transmission of a stereo stream to two devices may increase latency, which will make use in dynamic games uncomfortable.
⚠️ Attention: When connecting a second headset, the volume may automatically decrease. This is normal system behavior to protect hearing and save battery.
Priority control is automatic: if you receive a call, the music in the headphones is paused. If you want the call to go through the phone speaker and music to play through the headphones, you need to configure this in the developer options or special applications.
The system remembers up to 10-15 recent devices, but for stable operation it is better to remove from the list those headsets that you have not used for a long time.
Resetting settings and deleting profiles
Sometimes the software failure is so deep that only a complete reset of the device profile helps. This does not delete data from the phone, but it erases the history of all Bluetooth connections.
To do this, go to Settings → Bluetooth. Click on the gear next to the problematic device and select Cancel pairing or Delete. Confirm the action.
If a global reset of network settings is required (this will also delete saved Wi-Fi networks and mobile data settings), use the path Settings → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.
After this procedure, the phone will be like new in terms of network connections. You will have to re-enter your Wi-Fi passwords and re-pair all wireless accessories.
- 🗑️ Delete old pairs of devices that you no longer own to avoid cluttering the list.
- 🔌 When resetting your network settings, make sure you have Internet access to quickly re-set up Wi-Fi.
- 💾 Before a global reset, make sure that important data is synchronized with your Mi Cloud or Google account.
After deleting the profile, be sure to turn off and on Bluetooth on your phone so that the module restarts with a clean list of devices.
Why do the headphones connect, but there is no sound?
Most often the problem is in the profile. Go to the Bluetooth settings, click on the gear next to the device and make sure that the switch Media Audio is active. If it is turned off, the phone sees the headset only as a device for calls.
Can AirPods be connected to Xiaomi Redmi?
Yes, AirPods work like regular Bluetooth headphones. You'll be able to listen to music and talk, but features like automatically switching between Apple devices or showing the exact charge of each earbud in the curtain won't work without third-party apps.
How to improve the quality of the microphone during calls?
In the developer settings (if they are enabled), you can try changing the setting Absolute Volume or choose another codec for voice, for example, mSBC instead of CVSD, but this depends on the support of the headset itself.
What to do if the sound lags behind video?
Audio delay (latency) is typical for the SBC codec. Try turning on HD Audio in your Bluetooth settings to use aptX Low Latency. Also close background applications that load the processor.
Is it safe to leave Bluetooth on all the time?
From the security point of view of modern protocols, yes. However, this consumes battery power. If you do not use a headset or watch often, it is better to turn off the module through the notification shade to save energy.
