Modern Xiaomi smartphones are equipped with advanced Bluetooth modules, which makes it easy to synchronize them with a variety of acoustics. The process of connecting wireless headphones takes only a few seconds if you know the right procedure. However, users often encounter nuances of the interface of the shell MIUI or HyperOS, which can confuse the beginner.
In this article, we will look at all the stages of pairing, from activating the search mode on the headset to fine-tuning the codecs. You will learn to eliminate typical connection errors and optimize the sound for games or listening to music. The critical point is the correct sequence of the pairing mode on the headset itself, because without it, the phone will not be able to detect it.
Whether you’re using proprietary AirDots or third-party models from Sony and JBL, the basic principles of Bluetooth in Android remain the same. We’ll look at universal methods that will suit any device in the Xiaomi ecosystem, including budget Redmi and flagship Mi.
Preparation of headphones for pairing
The first step is always to put the headset in visibility mode. Many users mistakenly believe that it is enough to just turn on the device, but for the first connection it is not enough. Headphones must actively "scream" about their presence on the air so that the smartphone can find them.
For most TWS (True Wireless Stereo) models, both earbuds must be removed from the case and touch pads or physical buttons must be pinched. The indicator usually flashes white or red-blue to signal readiness for (mating).
- 🎧 Press the button on the case on 3-5 seconds before the indicator flashes quickly.
- 🔋 Make sure the headphone battery is at least 20% for stable operation.
- 📱 Keep the headset no more than 1 meter away from the smartphone during setup.
If you have a full-size model, the algorithm is often similar: long-term retention of the power button or a separate Bluetooth button. PIN-A code whose standard value is 0000 or 1234.
💡
If the light flashes slowly or is on with a steady light, then the pairing mode is not activated. Try turning off the headphones and repeat the procedure of pressing the button again.
Bluetooth settings in the Xiaomi interface
After the peripheral is ready, we'll move to the smartphone settings, and in the MIUI shell, the Bluetooth menu is prominent, but it has its own display features, so open the settings and select the Bluetooth partition or use the notification curtain.
The system will automatically start scanning the available space, and the name of your headset should appear on the "Available Devices" list, and note that sometimes the device can be displayed twice: as an audio output and as an input device (if you have a microphone).
Click on the model name to initiate the connection. The system can request a pairing confirmation — press OK or Connect. Once the link is successfully established, the battery icon or Connect status will appear next to the name.
☑️ Checking Bluetooth connection
Advanced sound and codec settings
Once successfully connected, Xiaomi offers users a deeper understanding of data quality settings, especially for audiophiles who want to make the most of their High-Res headphones. The standard SBC codec is often inferior in quality to more advanced peers.
To access hidden settings, go to Settings → Bluetooth, click on the arrow next to the name of the connected headphones. Here you will find the item "Bluetooth Codec." If your headset supports aptX, LDAC or AAC, the system will suggest switching to them automatically or manually.
⚠️ Note: Use of high resolution codecs (LDAC, aptX HD) can significantly increase the battery consumption of the smartphone and the headphones themselves, and also cause small delays in games.
You can also configure noise reduction functions in this menu if they are supported by a specific headphone profile, and some models allow you to switch transparency modes directly from the Xiaomi interface, bypassing touch control on the body.
| Codec | Sound quality | Delay (MS) | Compatibility |
|---|---|---|---|
| SBC | Basic | 150-250 | All devices. |
| AAC | Good. | 100-150 | iOS, Android |
| aptX | High. | 40-80 | Qualcomm chips |
| LDAC | Hi-Res | 100-200 | Android 8.0+ |
Managing two devices at the same time
Modern versions of Android onboard Xiaomi smartphones support Dual Audio, which allows you to stream sound to two pairs of headphones at once, which is the ideal solution for co-watching a movie or listening to music in the company.
To activate this feature, plug the first pair of headphones in the usual way. Then, without turning off the first device, put the second pair into pairing mode and connect it through the Bluetooth menu, the system automatically redirects the audio stream to both outputs.
It is important to consider that when you connect two devices, the load on the Bluetooth module increases, the range can decrease slightly, and in rare cases, micro-latency synchronization between channels is possible.
What if the sound comes from only one earpiece?
Solving Typical Connection Problems
Despite the stability of the technology, sometimes there are failures: the phone can see the headphones but not connect, or the sound can be interrupted, most often the problem lies in a crowded Bluetooth cache or a conflict of profiles.
The first thing you need to do is forget the device. Go to Bluetooth settings, click on the gear icon or arrow next to the headphone name, and select Remove or Forget the device. Then repeat the pairing procedure from scratch.
- 🔄 Reboot your smartphone – this clears up temporary errors of the communication module.
- 📡 Turn off Wi-Fi for connection time as 2.4GHz frequencies may conflict.
- 🔋 Check if the headphone battery is discharged, since at low charge the signal power drops.
If the problem persists, try clearing the Bluetooth service cache. To do this, go to Settings → Apps → All apps, find in the Bluetooth list (may need to enable system processes display) and click Clear cache.
Optimizing work for games and calls
Minimum latency is critical for gamers. Xiaomi smartphones have a game mode that prioritizes Bluetooth connectivity to reduce lag. Activate Game Turbo through the sidebar while playing.
When calling, voice quality matters. If someone complains about a quiet voice, check the microphone settings. In some cases, switching the codec to the one that is better optimized for voice (usually mSBC or standard SBC), although modern codecs like aptX Adaptive can switch automatically, helps.
Also worth mentioning is the MI Sound feature, which allows you to customize the equalizer to a specific headphone model. Go to Settings → Sound and Vibration → Mi Sound and select the profile as close as possible to your model, or adjust the frequencies manually.
💡
Game Turbo not only optimizes the performance of the processor, but also redistributes the priorities of Bluetooth packets, which reduces the sound latency to a minimum.
