Modern Xiaomi and Redmi smartphones have powerful multimedia capabilities, but the sound quality of the built-in speaker is often inferior to external audio devices. Users often face the need to connect a headset to listen to music, watch videos or play games without interference. The pairing process can vary depending on the type of accessory used and the version of the MIUI or HyperOS operating system.
In this article, we will take a look at all the available connection methods, from the classic pin connector to advanced wireless protocols. You will learn about the intricacies of audio codecs, how to fix common errors and secrets that will help unlock the potential of your acoustic system.
Use of wired connection via 3.5 mm connector
Many Xiaomi smartphones still feature a standard audio jack, which is a huge plus for fans of high-quality sound without the need for adapters. To get started, simply insert the headset plug into the appropriate hole before the characteristic click.
If you don't automatically switch, you need to check your settings manually. Go to Settings → Sound and vibration → Output and make sure you pick the right source. Sometimes it helps to simply restart the device if the audio driver fails on the first connection.
Consider that sound quality is directly dependent on the type of cable used and the headset itself. Cheap models can create background noise or have unbalanced frequencies. Flagship owners can appreciate support for Hi-Res Audio if they connect compatible headphones.
⚠️ Warning: When removing the plug, always hold onto a metal or plastic base, rather than pulling the wire itself to avoid breaking contacts inside the cable.
💡
Use a 3.5mm USB-C adapter with built-in DAC (DAC) if your smartphone doesn’t have a separate audio chip – this will significantly improve sound quality.
The pairing of Bluetooth headsets and TWS-headphone
Wireless connectivity is the most popular use case due to the lack of wires and convenience.Be sure to make sure your system is ready before starting the procedure. TWS-The headphones are charged and in pairing mode, and usually you need to press the touchpad or the button on the case body before the flashing light starts.
On the Xiaomi smartphone, do the following:
- 📱 Open the notification curtain and (click) the Bluetooth icon.
- 🔍 Wait for the scanning of available devices to end in range.
- 🎧 Click on the name of your headset in the list of found devices.
- ✅ Confirm the pairing request if it appears on the screen.
Once the connection is successful, the system can offer to configure noise reduction or equalizer functions through the Xiaomi Earbuds app. For stable operation, it is important that the Bluetooth version on the smartphone and headphones is compatible. Current models support the aptX Adaptive and LDAC protocols, which provide high-resolution audio transmission.
☑️ Check before buying Bluetooth headphones
Customization of audio codecs and audio in MIUI and HyperOS
Xiaomi’s operating shells provide advanced options for fine-tuning the audio stream. In the Settings menu → Sound and Vibration → Sound quality and effects, you can activate various improvements. Here you can access presets equalizers such as Rock, Pop or Jazz, as well as the ability to manually adjust frequencies.
For advanced users, choosing a Bluetooth codec is important. By default, the system chooses the most compatible option, but you can force the switch to a higher quality one. This is done through the developer menu, which is activated by clicking seven times on the build number in the About Phone section.
In the menu that opens, find the Audio section and select your preferred codec from the list:
- 🎵 SBC — Basic codec, ensures compatibility with all devices.
- 🎼 AAC — standard for Apple devices, gives good quality in compression.
- 🔊 aptX – technology from Qualcomm for sound transmission CD-quality.
- 🎧 LDAC — Sony codec transmits 3 times more data than standard codec SBC.
⚠️ Note: Use of high resolution codecs (LDAC, aptX HD) can significantly faster consume battery power as a smartphone and headphones.

Solving Display and Connection Problems
Sometimes people are faced with a situation where the headphones are connected, but the sound is not coming, or the device does not see the headset at all. The first step should always be to check the volume. In Android, there are separate volume sliders for media, calls and alarm clocks. Make sure that the media volume is twisted.
If the problem persists, try "forgetting" the device in the Bluetooth menu and creating the pair again. A common cause of failures is the accumulated cache of the Bluetooth service. You can clean it through Settings → Apps → All applications → Show system → Bluetooth → Memory → Clean.
The table below shows common symptoms and methods of their elimination:
| Symptoms. | Possible cause | Method of decision |
|---|---|---|
| Headphones not visible in search | The pairing mode is not activated | Press the button on the case until blinking |
| The sound is intermittent | Signal interference or low charge | Get closer to the source, charge |
| No sound in games. | The conflict of audio priorities | Restart the app or phone |
| Only one headphone works. | channel-synchronization | Reset your headphones to the factory |
Use of adapters and USB-C headsets
Many modern Xiaomi models lack the classic 3.5mm connector, which forces the use of digital interfaces. Connecting via a USB Type-C port requires a digital-to-analog converter (DAC) inside the headset or adapter itself. Analog headphones without a built-in DAC will not work through the adapter.
When choosing an adapter, pay attention to support for the Audio Class 1.0/2.0 protocol. Cheap Chinese counterparts can not work properly at volume or cause cracking. Xiaomi original accessories usually do not have these problems and provide stable signal transmission.
If you use an adapter, the system may not display the headphone icon in the status bar, but the sound will be redirected automatically.In some cases, you need to install third-party apps to force the external DAC to turn on if the smartphone does not recognize it automatically.
⚠️ Note: Not all adapters USB-C 3.5mm compatible with all smartphones, make sure the accessory supports the analog audio standard if it doesn't have an embedded chip.
💡
Digital USB-C headphones and high-quality DAC adapters provide sound better than the built-in audio track of most mid-range smartphones.
Additional functions and sound control
Xiaomi's ecosystem allows you not only to listen to music, but also to control playback. Most headsets support track and volume control through buttons on the body. To adjust actions with double or triple pressing, you may need a proprietary application, such as Xiaomi Buds or Mi Wear.
Also worth mentioning is the Mi Sound Enhancer feature, which software improves the sound in headphones by expanding the stereobase, which can be activated in the audio settings, and in Game Turbo, there is an option to improve the positioning of the sound, which gives a tactical advantage in shooters.
Remember to update the firmware of the headphones themselves. Manufacturers regularly release updates that fix connection bugs and improve the operation of the noise cancellation system. You can check for updates on the Bluetooth menu by clicking on the gear icon next to the device name.
