How to increase the volume of headphones on Xiaomi smartphones: all ways from simple to advanced

You've connected your headphones to Xiaomi, but the sound is too quiet, even at maximum volume? The problem is familiar to many smartphone owners of this brand - the manufacturer's limitations, MIUI firmware features or hardware limits can turn down the volume. In this article, we'll look at 7 proven ways to make the sound louder, from standard settings to hidden functions of the engineering menu.

It's important to understand that not all methods are equally safe. Some can damage the headphone speakers or damage the sound quality. We'll list the risks in each section so you can choose the best option. We'll start with the simplest solutions that don't require super-user rights.

1. Check basic sound settings in MIUI

Before digging deeper, make sure the problem isn't with the standard settings. Xiaomi often hides volume sliders in non-obvious menus.

• 🔊 Separate adjustment for headphones: B MIUI 12-14 The volume for the headphones and speakers is adjusted separately. Connect the headphones, then press the volume button, and a separate slider will appear.
• 🎵 Equalizer and Effects: Go to Settings → Sound and vibration → Sound quality. Turn off all effects (e.g. Mi Sound Enhancer) as they can turn down the volume.
• 🔄 Resetting sound settings: In the same menu, click “Reset audio settings” – this will return factory settings that sometimes work better than custom ones.

If the sound is still quiet after this manipulation, move on to the next section. Note: on some models (for example, Xiaomi 12 Pro or Redmi Note 11) there is an option in the Sound Quality menu called “Adaptive Sound” – it should also be turned off, as it automatically lowers the volume depending on the ambient noise.

2.Use of the developer mode to increase volume

MIUI has a developer mode that allows you to fine-tune the sound settings, and here's how to activate it and use it:

1. Go to Settings → About Phone and click on the MIUI version 7 times until the notification “You became a developer” appears.
2. Go back to the main settings menu, find a new section for developers (usually at the bottom of the list).
3. Scroll to the Network and Multimedia block and find the options: 🔊 Absolute Bluetooth Volume – Turn on if you use wireless headphones. 🎧 Turn off absolute volume control - is important for wired headphones.

After applying these settings, reconnect the headphones. On some firmware (for example, MIUI 13.5 for Xiaomi 11T Pro), these options may not be available - this depends on the version of the software. If you do not find the right items, try updating the system or move to the next method.

💡

If the sound starts to distort after the settings change, return the parameters to the original state, which is a sign that the headphones are not coping with the increased load.

3. Engineering menu: hidden volume settings

The Engineering Mode is a powerful tool for fine-tuning hardware settings, including amplifying sound. Careful: wrong actions here could cause system failures.

Instructions for entry:

1. Open the Phone app and enter the code: ##36446337## Some models (e.g. POCO X3 Pro) may have code ##4636##, but the desired section is missing.
2. Select Hardware Testing → Audio → Headset Mode.
3. In the Type field, enter Media, in Value, enter a number from 140 to 160 (maximum depends on the model).

Values above 150 can cause audio distortion or damage to the speakers! We recommend starting at 140 and gradually increasing as you test the sound quality.

4. Apps to amplify sound: top-5 provenance

If the standard methods didn't work, third-party apps will come to the rescue, and we tested dozens of programs and selected the 5 most effective for Xiaomi:

For most users, the best choice is Equalizer. FX — It combines amplifier and equalizer, does not require root and has minimal distortion. ViPER4Android It is suitable for advanced users who are ready to understand the settings IRS-profiles and convolutional filters.

5 Modification of system files (root only)

If you have a super-user license, you can change the system files that control volume, which is a maximum amplification method, but you need to be careful.

Instructions for experienced users:

1. Install Root Explorer or FX File Explorer with root access.
2. Cross the path: /system/vendor/etc/ Find the file. mixer_paths.xml (on some models — mixer_paths_qrd_skuh.xml).
3. Make a backup copy of the file, then open it in the text editor.
4. Find the lines with the parameters: <path name="headphone"> <ctl name="HPHL Volume" value="XX" /> <ctl name="HPHR Volume" value="XX" /> Increase the value by 10-15 units (for example, from 60 to 75).
5. Save the file, set the rights to 644 (rw-r--r---) and restart the phone.

⚠️ Attention: Incorrect editing mixer_paths.xml It can cause you to lose sound completely or get your phone looped on the boot. If you're not sure about your abilities, skip this method.

On models with a Qualcomm Snapdragon processor (for example, Xiaomi 12S Ultra or POCO F4 GT), the path to the file may differ:

/system/vendor/etc/audio_platform_info.xml

It's looking for parameters. speaker_gain and headphone_gain.

6. Hardware solutions: when the problem is not the phone

If the software methods didn't work, maybe the problem is with the headphones or the phone jack.

• 🎧 Headphone resistance: Headphones with impedance above 32 ohms (e.g. Beyerdynamic) DT The 770 Pro) requires an amplifier. Xiaomi does not do well with high-omnipotent load.
• 🔌 Connector pollution: Oxidation or dust in the 3.5mm connector (on models like the Redmi Note 9 Pro) reduces the quality of contact. Clean the connector with alcohol and cotton swab.
• 🔋 Battery wear: At a discharge below 20% MIUI Turns down the volume automatically to save energy.

If you use Bluetooth headphones, try:

• 📶 Switch to the aptX codec or LDAC (in the settings of Bluetooth-device).
• 🔄 Reset your headphone settings (press the power button for 10 seconds).
• 📱 Disable the dual connection function in Bluetooth settings – it can turn down the volume.

💡

On Xiaomi models with a MediaTek processor (such as the Redmi 10C), the problem of quiet sound is often caused by drivers, and updating the firmware to the latest version of MIUI can solve it without additional manipulation.

7. Alternative firmware: when nothing helps

If you've tried all the methods, but the sound on your headphones is still quiet, the radical solution is to change the firmware. Custom firmware (like LineageOS or Pixel Experience) often offers more flexible audio settings without the limitations of MIUI.

What you need to know:

• 🔓 Requires an unlocked bootloader and root.
• 📱 Supported models: Xiaomi Mi A2, POCO F1, Redmi Note 7/8 Pro et al. (full list at wiki.lineageOS).
• 🔊 In custom firmware, system amplifiers are available (for example, AudioFX), which are not available in the system. MIUI.

The process of installing firmware is beyond the scope of this article, but we recommend starting with the Pixel Experience - it is as close to "pure" Android as possible and has minimal sound bugs.

⚠️ Note: Create a backup of data through TWRP Or OrangeFox Recovery. Custom firmware installation resets the phone to factory settings and can result in a loss of warranty.
