In this article, we will not only break down the standard pairing process, but also look at the unique nuances of connecting Xiaomi headphones to Windows 7, including updating drivers, configuring Bluetooth services and solving typical errors like βThe device is connected, but there is no sound.β The Redmi AirDots, Mi True Wireless Earbuds and Mi models are also available. ANC Type-C, which most often cause questions among users.
If your laptop doesn't see the headphones or the connection is constantly being reset, don't be quick to blame the tech. 90% of the time, the problem is solved software-based, and we'll show you how to do it without going to the service center.
1. Checking the compatibility of Xiaomi headphones with Windows 7
Before you start connecting, make sure your Xiaomi headphones are compatible with Windows 7. Most models released after 2018 support Bluetooth 4.2 or 5.0, but additional drivers may be needed to work properly on the legacy OS.
Here are the key points to pay attention to:
- πΉ Bluetooth Version: Headphones with Bluetooth 5.0 (like Redmi AirDots 3 Pro) can connect to Windows 7, but with limited functionality (like no support). LC3 codec).
- πΉ Bluetooth Profiles: Make sure your laptop supports profiles A2DP (for sound transmission) and AVRCP (play-control).
- πΉ Adapter drivers: Built-in Windows 7 drivers often donβt recognize modern Bluetooth adapters. Youβll need manual installation from the manufacturerβs website (e.g. Qualcomm or Broadcom).
If your laptop is released before 2012, chances are that its Bluetooth module is running version 2.1 or 3.0. In this case, Xiaomi headphones can connect, but with constant communication interruptions or no sound.+ (For example, TP-Link UB400).
2.Laptop Preparation: Update of Bluetooth Drivers
The main reason for the failure of the connection is outdated or missing drivers. Windows 7 does not have built-in support for modern Bluetooth stacks, so they will have to be installed manually.
Follow this algorithm:
- Open Device Manager (click Win) + R, enter devmgmt.msc).
- Find the Bluetooth Radio Modules section or Network Adapters section (sometimes the Bluetooth adapter is hidden there).
- Right-click on your device (e.g. Broadcom 20702 Bluetooth) and select Update Drivers.
- Select Search for drivers on this computer β Select a driver from the list of already installed.
- If the list does not have a suitable driver, download it from the official website of the manufacturer of a laptop or chipset (for example, for Intel - from intel.ru).
To simplify the process, use the utilities of automatic driver updates:
- π§ DriverPack Solution (Free Edition).
- π§ Snappy Driver Installer (Offline).
- π§ IObit Driver Booster (paid, but with trial period).
π‘
If the Bluetooth panel has disappeared from the tray after the driver update, check the Bluetooth Support Service at services.msc. It should be started and configured to Automotive Mode.
3. Step-by-step instructions for connecting headphones
When the drivers are updated, you can start pairing. Let's look at the process with Redmi AirDots 2:
βοΈ Preparation for connection
Step 1. Put the headphones in pairing mode:
- For Redmi AirDots: Press the button on the case of the charging case for 5-7 seconds until the indicator starts flashing white and red.

Even after successful pairing, Windows 7 users are faced with errors, and consider the most common and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Laptop doesn't see headphones | Outdated Bluetooth stack or disabled adapter | Update drivers or enable adapter in Device Manager |
| Connection resets after 5-10 seconds | Conflict with energy conservation | Disable Allow Disconnection of this Device to Save Energy in Bluetooth Adapter Properties |
| The sound is interrupted or delayed. | Low Bluetooth version or interference | Use an external Bluetooth 4.0 adapter+ Or change the audio codec to SBC |
| The microphone is not working. | No support for HFP profile | Install a Broadcom or Qualcomm driver with Hands-Free Profile support |
If the headphones are connected but there is no sound, check:
- π Volume settings in volume mixer (sometimes headphones are muted separately).
- π Sound Format: Go to Device Properties β Additionally, select 16 bits, 44100 Hz (Quality) CD).

If after all the manipulations, the sound never appeared, try connecting the headphones to another device (for example, a smartphone), if the problem persists, the malfunction in the headphones themselves, not in the laptop.
5. Alternative ways of connecting
If standard Bluetooth pairing doesnβt work, consider alternatives:
1.Use of an external Bluetooth adapter
Adapters on a chip CSR 4.0 or Broadcom 20702 (e.g. Orico) BTA-403) They provide stable connectivity even on Windows 7:
- π Bluetooth support 4.0/5.0 backward-compatible.
- π Included are drivers for outdated OS.

When buying an external adapter, pay attention to support. A2DP β Without it, the headphones will connect, but the sound will not be transmitted.
6.Setting up energy saving for stable operation
Windows 7 is aggressively energy-saving, which often causes Bluetooth connections to break down.
Turn off the power saving for the Bluetooth adapter:
- Open Device Manager.
- Find your Bluetooth adapter, right-click β Properties.
- Go to the Power Management tab.
- Uncheck the tick from Allow this device to be turned off to save energy.
Set up a power supply plan:

- π Find the section The parameters of the wireless network adapter β Power saving mode and set maximum performance.
These settings are especially important for laptops with weak Bluetooth modules (such as Dell Inspiron or Dell Inspiron). HP Pavilion of the early 2010s).
Why do headphones turn off when the battery of the laptop is low?
7. Checking codec compatibility
Xiaomi headphones support several audio codecs, but not all of them work correctly with Windows 7:
| Codec | Support for Windows 7 | Sound quality | Delay. |
|---|---|---|---|
| SBC | Yes (embedded support) | Average. | ~100-150 ms |
| AAC | Partially (drivers required) | High. | ~80-120 ms |
| aptX | No (supported adapter required) | Very high. | ~40-60 ms. |
| LC3 | No. | High (for Bluetooth 5.2)+) | ~20-40 ms |
By default, Windows 7 uses SBC, And that leads to mediocre sound quality. AAC:
- Download and install Bluetooth Audio Receiver (e.g. BlueSoleil).
- In the program settings, select a priority codec AAC.
- Reconnect the headphones.
AptX will require an external adapter that supports this codec (e.g. Creative). BT-W5).
8.Resetting headphone and laptop settings
If all previous methods did not help, perform a full reset:
For Xiaomi headphones:
- π Place the headphones in the charging case.
- π Press the button on the case for 15-20 seconds until the indicator flashes red and white.
- π Get the headphones out - they will be reset to factory settings.
For the laptop:
- Remove all Bluetooth devices in the Control Panel β Devices and printers.
- Open Device Manager, find a Bluetooth adapter and select Delete.
- Restart the laptop β the drivers will be installed automatically.
- Repeat the connection process from scratch.
