How to increase the volume of headphones on Xiaomi: from standard settings to hidden MIUI features

You've connected your headphones to a Xiaomi smartphone, but the sound is too quiet, even at maximum volume? The problem is familiar to many owners of MIUI devices — the manufacturer artificially limits the volume level to protect hearing. But these restrictions can be circumvented by legal means without resorting to risky firmware manipulation.

In this article, we will analyze 7 proven methods - from basic settings MIUI Before working with the engineering menu and third-party applications, you will learn how to safely increase the volume without loss of sound quality, which Xiaomi models (including Redmi and other products). POCO) They support these functions, and what to do if the sound is still weak. MIUI 12-14 and Android 11-14.

Before you start settings, check the obvious: clear the 3.5mm connector (if any) of dust, update the firmware to the latest version, and test the headphones on another device. If the problem persists, read on.

1. Standard volume settings in MIUI

To start with, you may not be aware of the hidden audio options in MIUI. The manufacturer has added some useful features that many users are missing.

Open the Settings → Sound and vibration app. Here, pay attention to:

• 🔊 Amplify the sound in the headphones – an option available on some models (for example, Xiaomi 13 Pro, Redmi Note 12.
• 🎧 Equalizer – choose Preset Bass or Rock to emphasize low frequencies that are perceived as “loudness".
• 🔄 Adaptive sound – automatically adjusts the volume to the surrounding noise (works only with the original Xiaomi headphones).

If your MIUI version doesn’t have “Amprovement”, try to turn on the headphone mode in the same menu, which optimizes the output of sound for a specific headphone model (works with Mi True Wireless Earbuds, Redmi Buds, etc.).

⚠️ Attention: On models POCO F5, Xiaomi 12T And then again, when you activate "Amprovement of sound" you may get background noise. If it's critical, turn off the function and move on to the next way.

2. Engineering menu: hidden sound settings

The Engineering Mode allows you to manually adjust the sound card settings, including volume limits, which works on most Xiaomi devices, but requires caution – incorrect settings can lead to distortion of the sound.

To open the engineering menu:

1. Open the Phone app and enter the combination: ##36446337###
2. Go to the Hardware Testing → Audio section.
3. Select Headset Mode (for wired headphones) or Headphone Mode.
4. In the Max Vol field, increase the value from 144 to 160 (maximum 255, but it is dangerous for speakers!).

For Bluetooth headphones, the path will be different: Hardware Testing → Audio → Bluetooth → A2DP Volume. Here you can increase the Max Vol to 127 (standard – 100).

3. Sound amplification applications

If standard methods don't work, try third-party utilities that work on top of system settings and can increase volume by 20 to 30 percent without risking hardware.

Top.-3 tested applications:

• 📱 Volume Booster GOODEV — A simple booster with presets for different types of headphones. MIUI rootless.
• 🎛️ Equalizer FX — It combines equalizer and amplifier, allows you to point-to-point the frequencies, which visually increases the volume.
• 🔊 Precise Volume – gives access to hidden volume levels in Android, useful for Xiaomi models with limited range of adjustment.

Install any of these apps from Google Play, plug in your headphones and follow the instructions on the screen. Importantly, some utilities (like ViPER4Android) require Magisk and root rights, which voids the warranty.

💡

Before installing the sound booster, check it is compatible with your Xiaomi model.Some apps (like Equalizer FX) may conflict with the built-in MIUI equalizer - disable it in the audio settings.

4. Equalizer setting for visual volume enhancement

The human ear perceives low and high frequencies as "louder" than average. The right alignment of the equalizer can create the illusion of increased volume without changing the actual signal level.

How to set up:

1. Open Settings → Sound and vibration → Equator.
2. Select the preset "User."
3. Lift sliders to 60 Hz (bass) and 10-12 kHz (high frequencies) by +3–+5 dB.
4. Reduce the average frequencies (250 Hz – 3 kHz) by -2 dB for balance.

For Bluetooth headphones, use an equalizer in a companion app (such as Mi Audio for Xiaomi Buds). If you don't, install Wavelet from Google Play (works without root).

Increase 60 Hz by +4 dB|

Increase 10 kHz by +3 dB|

Reduce 1 kHz by -2 dB|

Activate "3D-sound MIUI (if)-->

⚠️ Note: On Xiaomi 13 Ultra and POCO F5 Pro too aggressive equalizer settings can cause delays in games. For gaming, use the preset "Games" or turn off the equalizer completely.

5 Hardware solutions: adapters and amplifiers

If the software methods fail, the problem may be the weak amp in the smartphone itself, in which case external devices will help:

• 🔌 USB-C → 3.5mm adapter with amplifier – for example, Xiaomi Type-C to 3.5mm Audio Adapter or Apple USB-C to 3.5mm (It's working with Xiaomi. It's 15 to 20 percent louder with external DAC.
• 🎧 Bluetooth transmitter with amplifier - connects to USB-C It sends a signal to the headphones with amplified sound. BT-W5, FiiO BTA30.
• 🔊 Portable amplifier, such as FiiO A3 or iBasso DC05. Connects between smartphone and headphones, powered by battery.

For Xiaomi with a 3.5 mm connector (for example, Redmi Note 11, POCO M5), an inexpensive Zorloo ZuperDAC-S amplifier is suitable, which is inserted directly into the connector and does not require separate power supply.

6. Checking for program constraints

Sometimes the quiet sound in headphones is not due to hardware limitations, but to software bugs MIUI.

• 🔍 Do Not Disturb Mode – even if it is disabled, some apps (such as Mi Security) may limit sound. → Annexes → Permits → Autostart and disable Autostart for Mi Security.
• 📱 Restrictions for specific applications - in Settings → Annexes → App management select a player (such as Mi Music) and check if the check box is “Limit background activity".
• 🔄 Resetting sound settings - go to Settings → System system → Resetting settings → Reset the audio settings. It'll bring all the parameters back to factory settings, including the hidden constraints.

On Xiaomi models with a Snapdragon 8 Gen 2 processor (e.g. Xiaomi 14, POCO F6), overheating protection can work, which automatically reduces the volume under high load. Check the CPU temperature in the CPU Monitor app - if it is above 60 ° C, let the smartphone cool down.

7. Alternative methods: from root to firmware replacement

If none of these things work, there are radical measures that require technical skills and can be warranty-free, but give you maximum control over sound.

• 🛠️ Getting root rights + ViPER4Android — It allows you to fine-tune the sound tract, including volume limits.
• 🔄 Install custom firmware, like LineageOS or Pixel Experience, which is not limited. MIUI, but require unlocking the loader.
• 🔧 Modification of the file mixer_paths.xml — in this file (is in the /system/vendor/etc/) You have to change the values, you have to root and you have to know the syntax.

To unlock the bootloader on Xiaomi you need:

1. Link your Mi Account to your device in Settings → Additional → Unlock OEM.
2. Wait 7 days (compulsory requirement of Xiaomi)
3. Use the official Mi Unlock Tool utility.

⚠️ Note: On Xiaomi models from 2023 to 2026 (e.g. Xiaomi 14, Redmi Note 13 Pro)+) Unlocking the bootloader can lead to the Widevine block L1, Netflix and other streaming services will stop working HD-quality.

💡

Custom firmware and root rights give you maximum freedom in the setting of sound, but they are not warranty-free and can cause security problems. Use these methods only if other methods have not worked.
