Before you start settings, make sure that the problem is not with the headphones themselves. Try connecting them to another device (laptop, tablet or second smartphone). If the sound is played correctly, then it is with the Xiaomi settings. If the problem persists, maybe the cable, connector or one of the headphone speakers is faulty.

1. Check basic sound settings in MIUI

The first thing to do is to make sure that the system does not activate functions that affect the distribution of sound channels. MIUI There are several parameters that can lead to a "muttled" sound:

• 🔊 Balance of sound: If the slider is moved to the left or right, one of the channels will be louder or quieter.

2. reset Bluetooth settings (for wireless headphones)

If you use TWS-Headphones (e.g. Xiaomi Buds 4, Redmi Buds 5 or POCO Buds X1), The cause of the "muttled" sound may lie in an incorrect connection profile, in which case resetting Bluetooth settings will help:

3. Select Remove this device (or "Forget the device").
4. Turn off and re-enable the headphones in pairing mode (usually you need to hold the power button for 5-10 seconds until the indicator starts flashing white / blue).

On some models (such as the Xiaomi Buds 3T Pro), the reset is done via the Mi Earphones mobile app. If installed, open it, go to the headphone settings and select Reset to factory.

3.Use of the engineering menu (for advanced users)

If standard settings don’t work, you can try changing the configuration of the audio channels through the Hidden Menu, which is suitable for advanced users, as incorrect changes can lead to malfunctions in the audio system.

On some Xiaomi models (e.g. Redmi Note 11 or POCO X5), the 3.5mm headphone jack may not be fully compatible with other brands due to differences in the layout, in which case an adapter or replacement of headphones with original ones (e.g. Xiaomi Piston) will help.

💡

If you connect wired headphones to the phone, you can say, "Accessories not supported," it could mean that the phone recognizes them as a headset with a microphone, not as stereo headphones, and in this case, channel inversion is normal behavior.

5. Applications for forced change of sound channels

If hardware and software methods don't work, you can use third-party apps that allow you to manually swap left and right channels.

For use of SoundAssistant:

1. Install the app from Google Play.
2. Open it and go to the Sound Balance section.
3. Activate the channel exchange option (L)↔R).
4. Check the sound on the headphones.

Attention! Apps like ViPER4Android require root rights or installation through Magisk, which can disrupt the system or lead to loss of warranty. On Xiaomi models with a blocked bootloader (such as global versions), installing such applications may not be possible.

If none of these things worked, it's probably the hardware of the smartphone or the headphones that's the problem, and here are the most common malfunctions.

• 🔧 A damaged audio codec: The chip that handles the sound on the smartphone motherboard fails, in which case the sound can be played with distortions or inverted channels.
• 🎛️ Faulty connector Type-C/3.5 mm: oxidation, mechanical damage or disconnection of contacts lead to incorrect signal transmission.
• 🔊 Problems with headphone speakers: if one of the headphones is damaged speaker, the sound can "jump" into another channel.
