How to make the sound louder in headphones on Xiaomi smartphones: all working ways

You've turned on your favorite track, but the sound in Xiaomi's headphones is barely audible even at maximum? This problem is familiar to many owners of Redmi, Poco and Mi smartphones. The reasons can lie in both the software limitations of MIUI and the hardware features of the device. In this article, we will discuss 8 proven ways to increase the volume, from standard settings to hidden functions of the engineering menu.

It is important to understand that some methods require caution, for example, changing the settings in the engineering menu or using third-party applications can lead to audio distortion or even damage to the speakers. We will explain in detail which methods are safe and where to be extremely careful. If you use wireless headphones (for example, Xiaomi AirDots or Buds), some of the recommendations will be especially relevant for you.

So let's start with the simplest solutions that don't require any additional software or deep knowledge of Android settings, and if they don't work, we'll move on to more advanced techniques.

1. Check basic sound settings in MIUI

Before digging deeper, make sure the problem isn't in the obvious settings. MIUI often resets audio settings after updates or new devices are connected.

• 🔊 Multimedia Volume: Press the physical volume button and make sure that the Multimedia slider (not the Call or the Alarm) is set to maximum.
• 🎧 Headphone Profile: Connect the Headphones and go to Settings → Sound. → Sound quality and effects. Safe volume (limits sound level) can be activated here).
• 🔄 Reconnect the headphones: Remove the plug (or turn off Bluetooth) and reconnect. MIUI Incorrectly determines the type of connected device, which limits the volume.

If you use Bluetooth headphones, check the codec settings. In the same section, Sound Quality and Effects, you can choose between SBC, AAC, or aptX. For example, aptX often gives a cleaner sound, but sometimes AAC plays louder on some Xiaomi models.

2. Disable volume limit in developer settings

Android hides some of the audio settings behind the developer mode. In MIUI, this section allows you to disable system constraints, which often lower the volume for the user's "safety." Here's how to do this:

1. Activate Developer Mode: Go to Settings → About Phone and 7 times click on the MIUI Version. a notification will appear "You became a developer".
2. Go back to the main settings menu and find a new Developer section (usually at the bottom of the list).
3. Scroll down to Multimedia and find the option Disable Absolute Volume. Activate it.
4. Below may be the option to Turn off the Bluetooth Volume Limit – turn it on if you use wireless headphones.

After these changes, restart your smartphone. Please note that on some Xiaomi models (such as the Redmi Note 10 Pro or Poco X3 Pro), these settings may not be available or may be called differently. If you do not find the right item, move to the next method.

💡

If the section does not appear after activating the developer mode, try clearing the Settings cache (Settings → Applications → Application Management → Settings → Storage → Clear the cache).

3.Use of the Engineering Menu (MTK/Qualcomm)

The engineering menu is a hidden tool for deep tuning of the hardware components of a smartphone. On Xiaomi with Qualcomm processors (most models) or MediaTek (such as Redmi 9A), you can manually increase the volume of the headphones. Attention: the wrong changes here can lead to audio distortion or damage to the speakers!

Instructions for Qualcomm:

1. Open the Phone app and type in the combination: ##36446337## (or #4636## → Phone information → Select test type → Audio).
2. From the Audio menu, select Headset Mode (or Headphone Mode).
3. Check the current Max Vol values for Media, Voice Call and Ring. Standard values are usually 80–100. Increase them by 10–20 units (e.g., 110–120), but don’t exceed 150!
4. Press Set and restart the device.

For MediaTek:

1. Enter the phone keyboard: ##36446337## or #54298##.
2. Go to Hardware Testing → Audio.
3. Select Headphone and manually increase Volume values for Normal Mode and Headset Mode.

4. Apps to amplify sound: top-5 tested utilities

If the system methods didn't work, third-party applications will come to the rescue, and we tested dozens of utilities and selected those that work well on Xiaomi without critical bugs. Importantly, some applications require root rights, but most do without them.

We recommend starting with the Equalizer FX or Wavelet, which gives a noticeable increase in volume without severe distortion. If you need maximum amplification and you are willing to sacrifice quality, try the Volume Booster, but do not forget the risk of damaging the speakers with prolonged use at high levels.

Make sure that security settings allow installation from unknown sources (Settings → Applications → Special Access → Install Unknown Applications)

Before installing ViPER4Android, check compatibility with your Xiaomi model at the 4PDA forum.

Create a restore point in TWRP (if there is root) to roll back when you have a sound problem.

After installation, restart your smartphone so that the changes take effect.-->

5. Equalizer settings in MIUI Music and third-party players

Many users don't realize that the standard MIUI Music player has a built-in equalizer that can increase perceived volume.Even if you're using Spotify or YouTube Music, setting up the system equalizer will affect the sound.

How to set up:

1. Open the Music app (standard MIUI player).
2. During the playback of the track, tap on the icon. ⚙️ Settings in upper right corner.
3. Select the Equalizer and activate it.
4. Choose Rock or Pop presets – they usually amplify the medium and high frequencies, making the sound subjectively louder.
5. Manually lift the sliders by 3-5 dB in the range of 100 Hz – 1 kHz (this will add the “body” to the sound).

For Spotify and YouTube Music:

• 🎵 In Spotify: Settings → Reproduction → equalizer → Activate and select Preset Loudness.
• 📺 YouTube Music: Settings → equalizer → Increase the sliders in the range of 250 Hz – 2 kHz.

The equalizer doesn't increase physical volume, but by adjusting the frequencies, the sound is perceived as more saturated and "louder," which is absolutely safe for headphones and smartphones.

💡

The equalizer is the only way to increase volume without the risk of damage to the speakers or distortion, and is especially effective for cheap earphones with poor frequency performance.

6 Hardware problems: when software methods don't help

If none of the software methods worked, the problem could be in the hardware, and here are the most common causes and signs:

• 🔌 3.5mm contaminated connector: If you use wired headphones, check the connector for dust or oxidation. Clean it carefully with a wooden toothpick (not metal objects!).
• 🔋 Weak amplifier in a smartphone: Some Xiaomi models (e.g. Redmi) 7A or Redmi 8) They have a weak built-in headphone amplifier, and in this case, only external ones will help. USB-C/DAC.
• 🎧 Damaged headphones: Connect other headphones to your smartphone. If the sound gets louder, the problem is your headphones. Check the integrity of the wire (especially the plug) and the membranes.
• 📶 Bluetooth interference: Wireless headphones can lose volume due to weak signal.Make sure there are no obstacles between the smartphone and the headphones (walls, metal objects).

To diagnose hardware problems:

1. Connect your headphones to another device (PC, other smartphone), and if the sound is quiet everywhere, the problem is with the headphones.
2. Try to play the sound through the speaker of your smartphone, if it's loud and the headphones are quiet, it's the jack or the amplifier that's to blame.
3. Install SoundAbout and force the sound to be redirected to the headphones, and if that doesn't work, it's a hardware problem.

💡

If you suspect a 3.5mm connector malfunctioning but are afraid to clean it yourself, use compressed air (a tank for cleaning equipment).

7.Alternative solutions: from USB-C adapters to custom firmware

If standard methods don’t work, consider these options:

• 🔗 USB-C/DAC Adapter: Cheap adapters (e.g. Xiaomi Type-C to) 3.5mm) They often have a weak amplifier. Try an external adapter. DAC, Like iBasso. DC05 Or AudioQuest DragonFly, which will make a clean, loud sound.
• 📱 Brush firmware: Firmware like LineageOS or Pixel Experience often have less aggressive sound limitations. Note that installation will require unlocking the bootloader and TWRP.
• 🔊 Magisk modules: For rooted devices, there are modules like the Audio Modification Library or JamesDSP that profoundly modify the Android sound stack.
• 🔧 Replacement of connector/amplifier: If the problem is hardware, contact the service center. On Xiaomi, replacing the 3.5 mm connector costs ~1000-1500 rubles, amplifier - from 2000 rubles.

Before installing custom firmware or Magisk modules, make sure they are compatible with your Xiaomi model. F3 One firmware will do, and another for the Redmi Note 11. 4PDA or XDA Developers.

8. Frequent mistakes and how to avoid them

When you try to turn up the volume, many users make mistakes that lead to the opposite result - the sound gets worse or disappears altogether.

• 🚫 Set volume to maximum in the engineering menu: Values above 150 in the Max Vol lead to distortion and the risk of burning the speakers. Optimal range is 110-130.
• 🚫 Use "sound amplifiers" without feedback: Many apps in the Play Market (like Super Volume Booster) are dummy or malware. Check ratings and reviews before installing.
• 🚫 Clean the connector with metal objects: Needles or paper clips can damage the contacts. Use only wooden or plastic tools.
• 🚫 Ignore updates MIUI: Newer versions of firmware often fix sound bugs. Check for updates in Settings → The phone. → Updating the system.

Also avoid using multiple amplification methods at the same time, for example, if you turn up the volume in the engineering menu and use the Volume Booster, the sound can be distorted beyond recognition. Choose one method and test it in different scenarios (music, video, calls).

💡

If the sound is hoarse or intermittent after the changes, immediately return the settings to standard. Prolonged playback of distorted sound at high volume can physically damage the earphone dynamics.
