Use of wireless TWS-Headphones from Xiaomi (Redmi Buds, AirDots or Mi True Wireless series) significantly improve comfort when working at the computer, but the Windows 7 operating system does not always correctly recognize new Bluetooth devices without prior preparation. Unlike the more modern versions, the Seven requires manual intervention to install the right drivers and activate detection services.
The challenge is that many users try to plug their headphones in right after they're removed from the case without putting them in pairing mode, which leads to search errors or audio inability to play back. In this article, we'll look at all the nuances of pairing, from checking the laptop hardware to fine-tuning the codecs.
Checking for Bluetooth adapter and installing drivers
The first step is to make sure that your laptop is equipped with a wireless communication module at all. On older Windows 7 devices, there were often models without built-in Bluetooth, in which case you would need an external one. USB-Adapter. Check for the appropriate icon in the Control Panel → Device Manager: If you see an unknown device or exclamation point, there are no drivers.
For the correct operation of Xiaomi Earbuds requires a full protocol stack, which in the “seven” is often absent by default. You will need to find and install drivers for your specific chipset (Realtek, Atheros, Broadcom).
Important: Don’t rely on automatic driver search through Windows Update, as support for Windows 7 has officially stopped and servers may not find the files they need.
⚠️ Warning: Installing Windows 10 or 11 drivers on the “seven” can cause critical system errors (BSOD). Use only versions marked as compatible with Windows 7.
After installing the software, restart your computer and make sure that the Bluetooth icon appears in the tray (near the clock). If the icon is not, check if the module is disabled by a physical button on the laptop case or by a key combination (often Fn + F5 or a key with an antenna image).
Activation of the pairing mode on Xiaomi headphones
The most common mistake is trying to connect without putting the headset into visibility mode. Xiaomi headphones of different series enter Pairing mode in different ways, and ignoring this step makes the device invisible to the computer.
For the Redmi AirDots and Mi True Wireless Earbuds Basic series, both headphones must be removed from the case. If they do not start flashing the white indicator automatically, press and hold the touch zones on both headphones for 5-7 seconds until the indicators start flashing quickly, only at this point the laptop will be able to "see" them.
In leg models such as Mi True Wireless Earphones 2, the algorithm may be different: sometimes you need to hold the button on the charging case itself when the lid is open.
What to do if the indicator does not flash?
Step-by-step connection instruction through the control panel
After getting the hardware ready and putting the headphones into search mode, we move to the software part. In Windows 7, the Bluetooth device management interface is slightly different from the newer versions and hidden in the depths of the menu.
Perform the following actions consistently:
- 📍 Click the Start button and enter the word “Bluetooth” in the search bar, then select “Changing Bluetooth settings».
- 📍 In the window that opens, make sure that the check box is “Allow Bluetooth devices to detect this computer».
- 📍 Go to the Start menu → Devices and printers».
- 📍 Click the “Add Device” button in the top toolbar.
The system will start searching for available gadgets when the name of your headphones appears on the list (for example, MI True Wireless EBs Basic_R), Select it and click "Next." Windows will try to install device drivers.
☑️ Checklist of successful connection
The process can take anywhere from 30 seconds to 2 minutes. If the system requests a confirmation code, type 0000 or 1234, although for modern systems, the process can be carried out in the form of a new code. TWS-The headset is rarely required.
Customization of sound reproduction and elimination of delays
Even after a successful connection, the sound may not go or be very quiet.This is because Windows 7 by default doesn't switch the playback profile to a Bluetooth device.
Right-click on the speaker icon in the tray and select Play Devices. In the list that opens, find your Xiaomi headphones. If none are available, right-click in the empty window and select Show Devices Disconnected and Show Devices.
Select your headphones, right-click and select "Use by default." Also go to Properties → Levels tab and make sure the volume is twisted to maximum.
💡
To minimize the latency of audio in games and videos on Windows 7, turn off the audio enhancements. In the headphone properties, go to the Improvements tab and check the "Disable All Sound Effects" box.
If you use headphones for calls (Skype, Zoom), make sure that your Xiaomi Earbuds are also chosen as the recording device, otherwise the interlocutor will not hear you, although you will hear him.
Compatibility table of profiles and codecs
Sound quality and functionality depend on the profiles supported. Windows 7 has limitations compared to Windows 10/11, especially in terms of high-resolution codecs.
| Profile/Code | Description | Support for Windows 7 | Impact on sound |
|---|---|---|---|
| A2DP | The main profile of stereo sound | Complete (through third-party drivers) | High quality music |
| HSP/HFP | Headset profile (mono) | Complete (native) | Low quality, only for calls |
| AVRCP | Reproduction management | Partial | |
| aptX / AAC | High quality codecs | Only with codecs from the manufacturer | Improves bitrate and detailing |
It is worth noting that the standard Bluetooth stack in Windows 7 often limits the performance of A2DP profiles, which can cause the sound to be monophonic or intermittent.
💡
Full A2DP stereo sound on Windows 7 often requires a third-party Bluetooth stack (such as Toshiba or Broadcom) to be installed if the native driver is not working properly.
If you notice that music is playing in low quality (as in a phone conversation), check if an app using a microphone is running.In this mode, Windows forcefully switches the profile to HSP, reducing the sound quality.
Solving Typical Connection Problems and Errors
Users often experience a laptop that sees headphones but says, "Device driver was not installed" or "Disconnected." This is a classic service conflict problem in Windows 7.
Try removing the device from the Devices and Printers list, then completely turn off Bluetooth on your laptop, restart your computer, and repeat the procedure again.
⚠️ Note: If the Bluetooth adapter is marked with a yellow triangle with an error code 43 in Device Manager, try turning off the Energy Savings option in the properties. USB-root concentrator to which the module is connected.
The problem can also be in a crowded Bluetooth cache: Cleaning the C:\Windows\System32\drivers\etc folder from unnecessary entries (for power users only) or using the Bluetooth Command Line Tools utility can help reset the suspended services.
Additional settings and optimization
To extend the work time of Xiaomi TWS and improving connection stability on older OSes, it is recommended to disable unused Bluetooth services. → services.msc) and find the Bluetooth Support Service. Make sure the startup type is Automatic rather than Manual».
If you use a laptop in a place with a lot of Wi-Fi networks (office, hostel), the Bluetooth signal (2.4 GHz) can be jammed. Try switching Wi-Fi to 5 GHz if the router supports dual-band mode.
Regularly update the firmware of the headphones themselves via the Mi Wear or Xiaomi Earbuds app on your smartphone before connecting to your PC. New versions of the software often contain compatibility patches with older Bluetooth stacks.
