Wireless headphones have become an integral part of everyday life β they allow you to listen to music, answer calls and watch videos without entangled wires. TWS-In this article, we will analyze not only the basic pairing procedure, but also the nuances of the configuration for different models of headphones (Redmi Buds, Mi True Wireless, Haylou, etc.), and also solve typical problems - from the lack of sound to constant communication interruptions.
The feature of Xiaomi phones (including the Redmi, POCO and Mi lines) is the MIUI shell, which can make adjustments to the standard connection process. For example, some firmware versions require additional permission to access geodata for Bluetooth to work, which is often overlooked. We will take into account all such moments to make your headphones work the first time.
1. Preparation of headphones and telephone for pairing
Before you start connecting, make sure both devices are ready to interact: the headphones should be charged (at least 30% of the battery), and the phone is freed from background tasks that can interfere with finding devices.
For most Xiaomi models (Redmi Buds 4 Pro, Mi AirDots Pro 2, etc.), the pairing mode activation occurs automatically when first removed from the case.
- π Charging the case: connect the case to the power source for 10-15 minutes, even if the indicator shows charge.
- π± Cleaning up Bluetooth cache on your phone: go to Settings β Annexes β Application management β Three dots (menu) β Show system-based β Bluetooth, then press Clear Cache.
- π Reset headphones: For most models, press the button on the case (or touchpad on headphones) for 10-15 seconds until the indicator starts flashing red and white.
β οΈ Note: If your headphones were previously connected to an iOS device (such as an iPhone), before pairing with Xiaomi, perform "Forget this device" in the Bluetooth settings on the iPhone. Otherwise, there may be a conflict of profiles. A2DP.
2. Step-by-step instruction for connecting via Bluetooth
Now, the pairing process itself is universal for all Xiaomi smartphones based on MIUI 12-14, but may be slightly different for older versions (for example, MIUI 11 and below).
- Activate Bluetooth on your phone: Open Settings β Connections & Sharing β Bluetooth and move the slider to the βOnβ position. Alternatively, swipe down the screen to open the Quick Settings Panel and press the Bluetooth icon.
- Translate the headphones to pairing mode: Remove the headphones from the case (they must automatically turn on). If the indicator on the case or headphones does not flash white / blue, press the touch panel or button for 3-5 seconds.
- Find headphones in the list of devices: In the Bluetooth menu on the phone will appear the name of your headphones (for example, "Redmi Buds 3 Lite").
- Confirm pairing: If you receive a request for code confirmation (usually 0000 or 1234), enter it. In most cases, the code is not required - just click "Connect".
βοΈ Checklist before connection
Once you've successfully connected, the Bluetooth device list will have a "Connected for Sound and Calling" status, and if you see "Connected for Calls Only" instead, you'll have no A2DP profile (responsible for music transfer) activated, and the solution to this problem is described in the troubleshooting section.
3. Customize Bluetooth sound and profiles after connecting
Xiaomi defaults to the headphones in the basic mode, but for full use, you need to adjust several settings, especially for models that support aptX or LC3 codecs (for example, Xiaomi Buds 4 Pro).
Go to Settings β Sound and Vibration β Bluetooth Sound Quality and select the best codec:
- π΅ SBC: universal codec, works with all devices, but with mediocre quality.
- π AAC: Best for music, supported by all Xiaomi and Apple devices.
- π aptX/aptX HD: High quality, but requires support from headphones (e.g. Mi True Wireless) 2S).
- β‘ LC3: New codec for Bluetooth 5.2+, sparingly consumes the battery.
| Codec | Bitreit | Xiaomi support | Latency |
|---|---|---|---|
| SBC | 328 kbps | All models. | 100-200 ms. |
| AAC | 256β320 kbps | All models. | 80-150 ms. |
| aptX | 352 kbps | Flagships (Mi 11 and newer) | 40-80 ms. |
| LC3 | 160β345 kbit/s | MIUI 13+ with Bluetooth 5.2 | 20-50 ms |
It is also recommended to enable the option of "Double audio" (in the same audio settings) if you want to use the headphones at the same time as a speaker or other device.
π‘
If the sound is interrupted after you connect, try turning off the Absolute Volume feature in the developer settings. Go to Settings β About Phone β MIUI Version (click 7 times), then Settings β Additional β For Developers, and deactivate the option to Turn off Absolute Volume Bluetooth.
4. Solving Connection Problems
Even if you follow the instructions correctly, you can have failures, and let's look at the most common mistakes and how to fix them.
4.1 Phone can't see headphones
If the headphones are not displayed in the list of available devices:
- π Reboot the phone and headphones (put the headphones back in the case, close the lid, wait 10 seconds, then remove again).
- π΅ Make sure the headphones arenβt connected to another device (like a laptop or tablet).
- π οΈ Update the phone firmware: Settings β The phone. β Updating the system.
4.2 Connection interrupted or sound lost
The reasons can be different β from interference to conflict profiles:
- πΆ Check the distance to the phone (optimally no more than 10 meters without obstacles).
- π Headphones under 20 percent charge can cause communication failures.
- ποΈ In Bluetooth settings, turn off the option "Automatic Shutdown of Audio Devices" (if any).
β οΈ Note: Some Xiaomi models (such as the Redmi Note 10 Pro) have a Bluetooth 5.0 bug where the headphones turn off when the screen is locked.Solution: Turn off Bluetooth battery optimization in Settings β Battery β Optimizing the battery β All applications β Bluetooth.
4.3 The sound is only in one earphone
