Wireless headphones have become an integral part of everyday life โ they allow you to listen to music, answer calls and watch videos without getting tangled wires. However, many Xiaomi Redmi users have difficulties when connecting for the first time: devices do not find each other, connection is interrupted or sound is distorted, this guide will help you understand all the nuances from basic settings to solving non-standard problems.
We will consider the pairing process on the example of popular models Redmi Note 12/13 Pro, Redmi 10/11 and POCO X5, but the instruction is relevant for older smartphones on MIUI 12-14. Particular attention will be paid to the settings of codecs (AAC, SBC, aptX), which affect the sound quality, and also to understand why some headphones (for example, AirDots or Sony WH-1000XM5) can connect not the first time.
If you have already tried to connect devices, but faced with the error โfailed to connectโ or headphones are constantly turned off โ at the end of the article there is a section with the diagnosis of problems and a table of compatibility of popular models of headphones with Redmi.
1. Preparation of headphones and telephone for pairing
Before you start connecting, make sure both devices are ready to go, which will eliminate 80% of the typical errors associated with a dead battery or the aircraft mode on.
For headphones:
- ๐ Charge headphones to at least 30% (most models refuse to turn on at a level below 15%). On Xiaomi AirDots and Redmi Buds, charging is checked by LED in the case: red - less than 30%, blue - more than 60%.
- ๐ฆ Get your headphones out of the case (if that's it) TWS-model - they must automatically turn on. If this does not happen, press and hold the power button. 3-5 seconds.
- ๐ Reset previous connections (if the headphones were already paired with another device). This usually requires holding the button on the case or earphone. 10-15 seconds before flashing the red/white indicator.
For the Xiaomi Redmi phone:
- ๐ถ Turn off In-plane mode in the notification curtain or through Settings โ SIM-maps and mobile networks.
- ๐ Reboot the Bluetooth module: turn it off in the curtain, wait 10 seconds and turn it back on.
- ๐ง Update the firmware: go to Settings โ The phone. โ System updates. Outdated versions MIUI (below 12.5) may not support new audio codecs.
Important! If you plug in Apple AirPods or Samsung Galaxy Buds headphones, note that they are optimized for their ecosystems. Xiaomi may not have gestures or Autostop Playback when you remove the earpiece from your ear.
2. Step-by-step instruction: how to connect headphones via Bluetooth

Instructions for MIUI 12-14:

- Activate the Bluetooth slider (it should turn blue) and the phone will start searching for available devices.
- Click on the name of your headphones in the list. If they are not, make sure they are in pairing mode (usually the indicator flashes white/blue).
- Confirm the connection on the phone (a window may appear with a request for permission). On some headphones (for example, JBL Live 660NC), you need to additionally press the button on the case.
- Wait for the message "Connected." In some cases, the sound will only appear after the music or video is triggered.
If the headphones require input PIN-code (rarely, but found in older models), try standard combinations:
- ๐ข 0000 is a universal code for most devices.
- ๐ข 1234 - Alternative version.
- ๐ข See the code in the headphone instructions (usually on the last page).
๐ก
If the headphones donโt appear in the list, try turning off and re-enable Bluetooth on your phone, and rebooting your headphones (most models need to hold the power button for 10+ seconds).
3. Customize sound and codecs for better quality
Once successfully connected, itโs worth optimizing your audio settings. By default, Xiaomi Redmi uses SBC (basic) or AAC (for Apple devices), but some headphones support more advanced formats like aptX or LDAC.
To change the codecs:
- Open Settings โ Sound and vibration โ Bluetooth sound quality.
- Select the connected headphones from the list.
- In the Audio codec section, select the available option. For example, for Sony WH-1000XM5, you should choose LDAC (high quality, but more battery consumption), and for Xiaomi AirDots 3, AAC (balance of quality and stability).
We also recommend that you include:
- ๐ง Sound enhancement โ bass and high frequency enhancement (not working on all models).
- ๐ Mono mode โ if one earphone is lost or discharged.
- ๐ต Adaptive sound โ automatic adjustment to ambient noise (available on the Internet) MIUI 13+).
| Codec | Sound quality | Delay (MS) | Battery consumption | Supported headphones |
|---|---|---|---|---|
| SBC | Average. | 100-200 | Low. | All Bluetooth headphones |
| AAC | Good. | 150-250 | Medium. | AirPods, Beats, Xiaomi AirDots |
| aptX | High. | 40-80 | High-pitched | Sony, JBL, Bose |
| LDAC | Maximum. | 50-100 | Very tall. | Sony WH-1000XM4/5, Sennheiser |
Note: On Redmi Note 10/11 and older, aptX and LDAC codecs are supported only on MIUI 13+ firmware. If the desired codec is not on the list, update the system.
