How to increase the volume in Xiaomi headphones: safe and effective methods

Have you ever encountered a situation where even at maximum volume, the music in Xiaomi headphones sounds too quiet? This is a common problem, especially on budget models like Redmi AirDots or Mi True Wireless Earphones. The manufacturer limits the maximum volume level for safety reasons to prevent hearing damage. But what if you are confident in your headphones and want to unleash their potential?

In this article, we will discuss 7 proven ways to increase the volume in Xiaomi headphones, from standard smartphone settings to hidden functions of the engineering menu and third-party applications. It is important to understand that some methods can cancel the warranty or damage equipment if used improperly. We will explain the risks in detail and give recommendations on how to minimize them.

Before you start settings, make sure that the problem is not with the headphones themselves. Check them on another device, clean the connectors (for wired models) and update the firmware of the smartphone. If the volume is still not enough, start optimizing.

MIUI Sound Settings: What Can Be Changed Without Risk

Starting with the safest method, using built-in MIUI tools, modern firmware versions offer several sound enhancement options that do not require superuser rights or interference with system files.

The first thing to check out is the eQUALIZER and the bass amplifier, which don't increase the physical volume, but they can make the sound more intense and clear, which subjectively improves the perception.

• 🎵 Open Settings → Sound and vibration → Equalizer.
• 🔊 Select the preset Bass or Rock, which amplifies the lower frequencies, which creates a louder effect.
• 🎧 Activate the Mi Sound Enhancer option (if available) to optimize the sound for headphones.
• 🔄 Turn on Adaptive Sound (in some versions MIUI) to allow the smartphone to automatically adjust the volume to the surrounding environment.

Another useful tool is the volume limiter, which is the default MIUI set hard limits, but you can relax them.

1. Go to Settings → Special features → Improve the sound.
2. Turn off the Volume Limit option (if it is active).
3. In some models (for example, Redmi Note 10 Pro) here you can turn on the Mono sound, which sometimes increases the volume in one headphone.

💡

If your MIUI version does not have the Equalizer option, try connecting your headphones and restarting your smartphone – sometimes the option only appears after the audio device is detected.

2. Engineering menu: hidden volume settings

To get a deeper sound setting, you can use the Engineering Mode, a hidden section that stores low-level device settings, including volume limits, and changes to the engineering menu can cause the audio system to run unsteady or even damage the headphones if you set the values too high.

To get into the engineering menu, follow the following steps:

• 📱 Open the Phone app and type the combination: ##36446337###
• 🔧 Some models (e.g. Poco F3) run the code: ##4636## → Select Hardware Testing → Audio.
• 🎧 Connect your headphones before you enter the menu, otherwise the audio options may not show up.

In the engineering menu you are interested in two sections:

1. Headset Mode — you can change the settings for wired headphones, Max Vol or Media Max Volume points are responsible for maximum volume.
2. Headphone Mode (or Earphone Mode) – similar settings for wireless headphones.

Recommended values for increasing volume:

💡

Do not set values above 180-200 – this can lead to overloading of the amplifier in the headphones and their failure.

⚠️ Warning: After you change the engineering menu, restart your smartphone. If the sound gets distorted or background noise appears, return the values to the standard and check the headphones on another device.

3. Apps to amplify sound: top-5 utility

If the standard methods didn't work, you can use third-party applications, and they work on two principles:

1. Software amplification – increase the volume due to sound processing algorithms (may reduce quality).
2. Bypassing Android restrictions – changing system volume settings (requires ROOT or ADB).

We have selected 5 reliable applications that are compatible with Xiaomi and do not contain malware:

• 🔊 Volume Booster GOODEV is a simple booster with presets for different types of headphones. It doesn't require root, but the efficiency depends on the model of the smartphone.
• 🎛️ Equalizer FX is a powerful equalizer with bass amplification and general volume. There are presets for Xiaomi and Redmi.
• 🛠️ ViPER4Android is a professional audio driver with support for FX and IRS. Requires installation via Magisk (for root devices).
• 📱 Precision Audio Mod — a modification of the system sound, increases volume by 20-30%. Compatible with MIUI 12/13.
• 🔧 SoundAssistant (from Samsung, but runs on Xiaomi) – allows you to fine-tune the volume for each type of content (music, video, calls).

The most effective solution on this list is ViPER4Android, but installing it requires unlocking the bootloader and obtaining root rights. If you are not ready for such radical measures, start with the Volume Booster GOODEV or Equalizer FX.

⚠️ Warning: Applications like Volume Booster can cause sound distortions at high volume levels. If you have wheezing or crackling, reduce the amplification or turn off the effects.

4. Modification of configuration files (for advanced)

This method is suitable for those who are ready to work with system files. It allows you to remove the volume restrictions at the firmware level, but requires the presence of ROOT- rights or access through ADB. An error in editing files can lead to loss of sound or cyclic restart of the device.

The main files responsible for volume limits in MIUI:

• /system/vendor/build.prop contains the ro.config.media_vol_steps (number of volume steps).
• /system/etc/audio_policy.conf – here are the maximum volume values for different output devices.
• /system/etc/mixer_paths.xml - Audio route configuration, including headphone restrictions.

For editing through ADB (no root):

1. Connect your smartphone to your PC and activate USB Debugging in Settings → About Phone → MIUI version (click 7 times).
2. Open the command prompt and type: adb pull /system/etc/audio_policy.conf This will copy the file to your computer.
3. Open a file in a text editor (like Notepad++) and find lines with speaker_volume or headphone_volume.
4. Increase your values by 10-15% (for example, from 85 to 95).
5. Save the file and download back: adb push audio_policy.conf /system/etc/ adb reboot

For users with ROOT, the process is simplified – you can use Root Explorer or FX File Manager to directly edit files.

5 Hardware methods: when software does not help

If all the software is exhausted and the volume is still low, the problem may be in the hardware.

• 🔌 Contact oxidation (for wired headphones). Clean the 3.5mm connector with alcohol and cotton swab. Xiaomi often uses connectors with dust protection, which accumulates dirt over time.
• 🔋 Battery discharge (for wireless headphones) When the charge level is below 20%, many Xiaomi models automatically turn the volume down.
• 🎧 Speaker wear. Over time, the headphone membranes lose their elasticity, which causes the volume to go down. Check on another device.
• 🔊 Smartphone audio chip malfunction. If all headphones are affected, the audio amplifier may have failed (a common problem with the Redmi Note 8/9).

For Xiaomi wireless headphones (such as AirDots Pro or Buds 3), there is another trick: resetting the settings:

1. Place the headphones in the case and close the lid.
2. Press and hold the button on the case for 10-15 seconds until the indicator flashes red.
3. Reconnect the headphones – sometimes it restores factory volume.

If you suspect a smartphone audio chip malfunction, you can temporarily use an external Bluetooth transmitter (such as the Xiaomi Bluetooth Audio Receiver) that connects to the headphones and transmits sound directly, bypassing the phone's built-in amplifier.

6. Alternative solutions: when nothing works

If all of the above methods fail, consider alternative options:

• 🔄 Headphone firmware update: Some Xiaomi models (e.g. Mi True Wireless Earphones 2) support software updates via the Mi Home app or Xiaomi Wear.
• 🎵 Use an external amplifier. For wired headphones, you can purchase a portable amp (e.g., FiiO A1) that connects to a 3.5mm connector.
• 🔧 Replace headphones. If your model is outdated (like the 2019 Redmi AirDots S), it may be time to upgrade.The new Xiaomi Buds 4 or FlipBuds Pro have improved speakers and support LDAC.
• 📱 Smartphone change. Some Xiaomi models (e.g. Mi 11 Ultra or Mix 4) use a separate Qualcomm Aqstic audio chip that provides a higher volume margin.

If you listen to music in low bitrate (for example, 128 kbps MP3), try the files in FLAC or AAC 320 kbps. The difference in volume can be as high as 10-15%.

7 Risks and how to avoid them

Turning up the volume above the factory limits is always associated with risks, and here are the main ones and ways to minimize them:

To minimize the risks, follow these rules:

• 🔍 Before any changes, test the headphones on another device to make sure they are working properly.
• 📉 Turn up the volume gradually — listen to music for 5-10 minutes after each change, checking for distortion.
• 🔄 If you use third-party apps, roll back changes if audio artifacts appear.
• 🛠️ For models with Qualcomm Snapdragon (e.g. Poco X3) you can use ADB to temporarily increase the volume without root: adb shell settings put global volume_steps 30 (increases the number of volume control steps).

⚠️ Warning: If you use headphones with impedance below 16 Ohms (for example, many Chinese models), the risk of damaging the speakers increases by 2-3 times as volume increases.
