Modern wireless headphones like the Xiaomi Buds 3 have become the standard for sound quality and autonomy, but their use is limited not only to smartphones. Many users want to enjoy their favorite music or watch movies on the big screen using a laptop as a signal source. The process of synchronizing devices may seem difficult due to the lack of a proprietary application on the PC, but this is only a superficial misconception.
In fact, the headset is connected to a computer running Windows 10 or 11 through standard Bluetooth protocols built into the operating system. You do not need to search for specific drivers or download questionable utilities, since the system itself recognizes the device as a high-quality audio codec. The main thing is to correctly activate the pairing mode on the headphones themselves, since they do not always automatically go into this mode when you open the case.
In this guide, we will take a look at all the details of the setup, from entering the mode (pairing) to fine-tuning the microphone parameters for video calls. You will learn how to ensure a stable connection and what to do if the laptop “can’t see” your Buds 3. Following the step-by-step instructions, you will be able to fully use the potential of your headset in conjunction with your computer.
Preparation of headphones for the pairing mode
Before you start searching for devices on your computer, you must force the Xiaomi Buds 3 to detect. Unlike some models that immediately become visible after extraction from the case, manual intervention is required to initially connect to the new gadget. Make sure that the headphones are inside the charging case and the cover is open.
On the back or bottom of the case is a functional button responsible for controlling the state of the device. You need to press this button and hold it for 2-3 seconds. The indicator located on the front panel will flash white, signaling that the headset is ready to connect.
⚠️ Warning: If the indicator flashes red, the charge of the case is critically low. 10-15 minutes before attempting to connect, otherwise the process may be interrupted.
It is important to understand that the pairing mode is active for a limited time. If you do not have time to find the device in the Bluetooth list on the laptop within 1-2 minutes, the search mode will turn off automatically and the procedure will have to be repeated.
💡
To save battery power, turn off Bluetooth on your smartphone while connecting your headphones to your laptop so that devices don’t conflict when you try to auto-connect.
Find and connect a device in Windows 10 and 11
Once you activate the headphone search mode, you go to the operating system settings. Windows 10 and 11 are different, but the logic of the actions remains the same. Open the Start menu and select the gear icon to enter the Settings section, or just press the Win + I key combination on the keyboard.
In the window that opens, look for the wireless connection section. In Windows 10, this is Devices, and in the eleventh version, it's Bluetooth and Devices. Make sure that the Bluetooth slider is moved to On. If the switch is missing or inactive, you may not have Bluetooth module drivers installed on your laptop.
Then click on the “Add Bluetooth or other device” button. In the window that appears, select the first item — “Bluetooth” (Mice, keyboard, pen or audio..) The system will start scanning the ether, and in a few seconds the Xiaomi Buds 3 item should appear in the list. Click on it to start the connection.
- 🔍 Open “Options” through the Start menu or hot keys.
- 📡 Go to the Bluetooth section and make sure the module is activated.
- ➕ Click Add Device and select Bluetooth type.
- 🎧 In the list, find Xiaomi Buds 3 and click to pair.
Once the connection is successful, the system will give a notification, "Device ready to use." Now the sound from the laptop will be broadcast to your headphones. However, to fully work the microphone and control may require additional adjustment in the sound control panel.
☑️ Connection check
Configuring playback and recording devices
Often, once connected, sound continues to go through the laptop speakers and the microphone in the apps doesn't work. This is because Windows doesn't always automatically switch the default playback device to the gadget you just connected. To fix this, right-click on the speaker icon in the tray (near the clock) and select "Sounds" or "Open audio settings."
In older versions of Windows, go to Control Panel -> Sound. On Playback, find your Xiaomi Buds 3 in the list. If there are more than one (such as Hands-Free AG Audio and Stereo), select the option with the word Stereo for listening to high-quality music. Right click and select "Use by default."
You need to do the same thing in the Record tab, find your headphone microphone, turn it on (if it's disabled), and also set it as the default device, which is critical for Zoom, Skype, or Discord, otherwise people may hear you through the built-in microphone of the laptop, which often creates an echo.
| Parameter | Stereo mode | Hands-Free mode |
|---|---|---|
| Sound quality | High (Hi-Fi) | Low (Mono) |
| Use of microphone | Unavailable. | Available. |
| Appointment | Music, movies | Calls, conferences. |
| Codec | SBC / AAC / LDAC | CVSD / mSBC |
And the thing about Bluetooth is that you can't have high-quality audio and microphones at the same time, and when you activate the microphone in the app, the system automatically switches the headphones to Hands-Free mode, and the quality of the music drops to the phone, which is normal behavior, not a defect in the headphones.
💡
For music, always choose Stereo mode, and for video calls, the system itself will switch to Hands-Free, but it is better to control this manually in the settings of a particular application.
Management and additional functions on PC
Unlike smartphones, on a computer you won’t be able to use Xiaomi’s proprietary Earbuds app to adjust the equalizer or reassign gestures.The whole control comes down to standard operating system features and multimedia keys.However, basic commands like Play/Pause, track switching and volume control work correctly through touch-based control on headphone legs.
To access the advanced sound settings in Windows, you can use the sound effects control panel. Press Win + R, type in mmsys.cpl and press Enter. In the properties of your headphones, you can try to turn on a virtual surround sound or equalizer if you don't have enough standard sound.
It’s also worth mentioning the ability to connect to two devices at once. Xiaomi Buds 3 supports Dual Device Connection. If your headphones have already been paired with a smartphone, just turn on Bluetooth on your phone and they’ll connect to both devices. Now you can watch videos on your laptop, and when you call in, the sound will automatically switch to your mobile phone.
⚠️ Note: When using the microphone on the laptop (Hands-Free mode), notifications from the phone may not play in the headphones or interrupt the audio stream, since the bandwidth of the channel is limited.
If you want to change the noise reduction settings (ANC) or transparent mode, you will have to use a smartphone. Changes made to the application on the phone (for example, noise reduction level) are stored in the memory of the headphones themselves and will act when you connect to the laptop.
The secret of dual connection
Solution: Laptop doesn't see headphones
When a computer ignores Xiaomi Buds 3, it is common and most often associated with software driver failures or a Bluetooth module cache. If you have completed all the steps according to the instructions, but the device does not appear in the list, try rebooting the Bluetooth service. Open the Device Manager (devmgmt.msc command), find the “Bluetooth” section, right-click on your adapter and select “Delete Device” and then restart the laptop.
Another common reason is that the headphones get stuck in connection mode to the last active device.If your Buds 3 was previously connected to a phone that is nearby and has Bluetooth enabled, they can automatically connect to it, ignoring the requests of the laptop. temporarily turn off Bluetooth on the smartphone or forget the device in its settings.
Also worth checking for Windows services: Press Win + R, enter services.msc, and find the Bluetooth Support Service. Make sure the startup type is set to Automatic and the service is running. If it is stopped, click Launch.
- 🔄 Restart your laptop and headphones (put in a case and close for 10 seconds).
- 🗑️ Remove the device from the list of known in Windows and try again.
- 📱 Turn off Bluetooth on your smartphone to rule out priority conflict.
- 🛠️ Update Bluetooth drivers through Device Manager or Manufacturer’s website.
In rare cases, the problem lies in the outdated firmware of the headphones themselves. Since you can not update them via your PC, connect them to your smartphone, launch the Xiaomi Earbuds app, check for updates and install them.
Optimizing the quality of sound and codecs
It is important for audiophiles to know which codecs support a bundle of laptop and Xiaomi Buds 3. These headphones support SBC, AAC and LDAC codecs. However, Windows by default often uses the basic SBC codec, which may not reveal the full potential of the headset. Verification and activation of advanced codecs is possible, but requires the appropriate Bluetooth adapter.
To check the current codec, run the command line on behalf of the administrator and enter a command that will display the Bluetooth properties of the device, but this information is hidden in the standard Windows interface. An easier way is to install third-party utilities such as Bluetooth Command Line Tools or view properties in specialized software from the adapter manufacturer (Intel, Realtek).
If your laptop is equipped with a modern Bluetooth 5.0 module and higher, the likelihood of using an AAC codec is high, which will ensure good transfer quality. To activate LDAC, you may need to install additional drivers or use alternative Bluetooth stacks, which is a task for advanced users.
Remember that noise quality is also affected by interference. 2.4GHz Wi-Fi routers can interfere with the Bluetooth signal. If you notice a crack or stutter, try moving your laptop away from your router or switching to 5GHz Wi-Fi.
⚠️ Attention: Use USB 3.0 devices (external hard drives) in close proximity to the Bluetooth antenna of the laptop can cause severe interference. USB-hub.
