Set up wireless headphones to the Xiaomi Redmi phone via Bluetooth

Modern Xiaomi Redmi smartphones come with advanced Bluetooth modules that allow high-quality audio transmission. However, the initial synchronization process of accessories can raise questions for users accustomed to automatic pairing. Proper tuning opens up access to hidden features of the MIUI or HyperOS shell that are not visible on a standard connection.

In this article, we will not only look at the basic algorithm of actions, but also look at the intricacies of working with codecs and device priorities. Bluetooth technology has undergone significant changes in recent years, and old methods may not work with new models of headsets. Understanding these nuances will allow you to avoid dissynchronizing sound and video.

Before we get to the practical steps, it's worth mentioning the importance of connection stability. If you plan to use headphones for games or watching movies, audio delay can be a critical problem, and optimizing system-level settings often solves this problem more effectively than flashing the accessory itself.

Preparation of the smartphone and accessory to pairing

The first step is always to check the battery charge of both devices.The low energy levels in the headphones can cause them to be out of sight in the list of available devices or the mating process to be interrupted halfway.Make sure the headset is at least 30-40% charged for the radio module to work smoothly.

Then you need to activate detection mode on the audio device itself. Unlike some other brands, Xiaomi headphones and third-party models often require forced switching to the mode (pairing), usually by holding the on button or a special pairing button on the case for a long time until the indicator starts flashing quickly.

⚠️ Warning: If the light flashes slowly or is on a straight light, the device is in standby mode or already connected to another gadget.

On the smartphone side, you should also pre-clean the list of old devices. Go to Bluetooth settings and delete records of previously used headsets that you no longer use. A crowded link cache sometimes causes driver conflicts, especially on older MIUI devices.

Make sure geolocation is enabled. In modern versions of Android, access to Bluetooth scans is often tied to location permission. Without that, the system search service might simply not run the ether scan.

Step-by-step connection instruction via Bluetooth menu

The MIUI and HyperOS connection process is standardized, but has its own display features. Open the Settings app and select Bluetooth. Make sure the slider is activated and the phone starts searching for devices within a 5-10 meter radius.

• 🔍 Click on the search or list update icon if the desired device does not appear within a period of time. 10-15 seconds.
• 📱 In the Available Devices list, find the name of your model, such as the Redmi Buds 3 Pro or Mi True Wireless Earbuds.
• ✅ Tap the name to initiate the pairing request.
• 🔐 If you request code confirmation or access permission, click Connect or enter 0000.

Once the connection is successful, the system will automatically distribute profiles: A2DP for music and HFP/HSP for calls. Connection status will appear in the notification curtain and battery widget if the Xiaomi ecosystem is used. In some cases, additional confirmation of access rights to contacts and call log may be required.

If the pairing is successful but no audio, check the audio output settings. Sometimes the priority of the sound remains on the speaker of the phone. Click on the gear next to the name of the connected device in the Bluetooth menu and make sure that the Media and Call Sliders are active.

Using the Xiaomi Earbuds app for advanced customization

To fully unlock the potential of wireless headphones, the standard Bluetooth menu is not enough. Xiaomi has developed a special application Xiaomi Earbuds (formerly Mi Buds M8), which is available in Google Play and GetApps. It is through this software that deep calibration of sound and customization of touch control takes place.

After installing the app and first running, it will automatically detect the connected headphones. The interface will prompt you to update the accessory firmware if a new version is available. The firmware update often fixes bugs with (break connection) and improves noise cancellation.

In the app, you can customize the control gestures. They can be uncomfortable by default, but the flexibility of the system allows you to assign a double touch, a long press or a triple tap for specific actions. Touch control becomes much more accurate after calibrating in the application.

⚠️ Warning: Do not interrupt the process of updating the firmware of the headphones. If the battery sits down while recording data, the device may turn into a “brick” and require maintenance repairs.

Customization of codecs and sound quality in the engineering menu

For audiophiles and users who value data quality, choosing the right codec is important. The standard Bluetooth protocol SBC provides basic quality, but modern codecs like AAC, aptX or LDAC are able to convey much more detail. Redmi smartphones often support an extended set of codecs.

To check and change the codec, you need to activate the developer menu. Go to Settings → About phone and quickly click on the build number (MIUI Version) 7 times. After the message “You became a developer”, go back to the main settings menu.

Settings → Additional settings → For developers → Bluetooth audio codec

In the list that opens, select your preferred codec. If your headphones support aptX Adaptive or LDAC, the system will suggest them in the list. Choosing a better codec can increase battery consumption, but improve sound detail when listening to Lossless tracks.

Not all apps support high-resolution audio, but streaming services can limit bitrate depending on your subscription settings, and make sure that the music player settings are set to the highest quality of playback.

Solving Connection and Signal Stability Problems

Even with the right setup, there can be situations where communication is unstable. A common problem is to desynchronize the left and right channels. To solve this problem, perform a full reset of the headphones. This is usually done by clamping the sensors on both earphones for 10-15 seconds until the indicators flash red.

Another common cause of interference is operating in an area with a lot of Wi-Fi networks or other Bluetooth devices. 2.4 GHz radio frequency interference can interrupt the flow of data. Try to move away from the router or turn off the data transfer on the phone over Wi-Fi for verification.

• 🔄 Forget the device in Bluetooth settings and create a pair again.
• 🔋 Charge the case and headphones to 100%, then discharge them completely and charge again.
• 📵 Turn off Bluetooth on other nearby devices that can automatically connect to the headset.

If the problem persists on only one particular phone, it may be the cache of the Bluetooth system service. Clearing the data of the Bluetooth system application through the application management menu can help. Find it in the list of system processes and click Clear Data.

💡

Use the code ##2832# in the dialer to log into the Bluetooth engineering test menu (not all Redmi models) to check the antenna signal strength.

Optimizing work for games and video content

When watching a video or playing a game, the latency can be critical. The standard Bluetooth latency is about 150-200 ms, which is noticeable to the eye. To compensate for this effect, there is often Game Mode in Bluetooth settings or in the headphone application.

Activating this mode puts the headphones in the forefront of data speeds at the expense of sound quality and energy saving, and latency is reduced to 60-80 milliseconds, making shooter shooting or rhythm games more responsive, but the battery runs out faster.

It’s also worth checking the settings of a particular app. Some video players, such as VLC or MX Player, have an Audio-Video Synchronization feature that allows you to manually shift the audio track to compensate for Bluetooth lags.

⚠️ Note: Game mode is incompatible with codec LDAC. When you turn on Game Mode, the system will automatically switch to the codec SBC or AAC provide low-latency.

Frequently Asked Questions (FAQ)

💡

A key factor in stable operation is the timely update of the headphone firmware through the official app, as manufacturers often release patches to improve compatibility with new versions of Android.
