How to increase the volume of headphones on the Xiaomi phone: all ways

You've connected your headphones to a Xiaomi smartphone, but the sound is too quiet? This is a common problem, especially on Redmi Note 10/11/12, POCO X3/X4 or Mi 11/12, where the manufacturer limits the default maximum volume. The reasons can vary from the software limits of MIUI to the hardware features of the audio chip. In this article, we'll look at 10 proven ways to increase the volume, from basic settings to hidden functions of the engineering menu.

It's important to understand that not all methods are equally safe. Some can cause sound distortion or even damage to the earphone speakers when used at maximum volume for long periods of time. We'll flag the risks in each section so you can choose the best option. Let's start with the simplest solutions and gradually move on to the advanced ones.

1. Check the basic sound settings in MIUI

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

• 🔊 Volume Control: Press the physical volume button and make sure the Media slider (not the call!) is raised to the maximum.Some Xiaomi models have a separate headphone regulator - you can see it when you plug in the headset.
• 🎧 Sound Profile: Go to Settings → Sound and vibration → Sound quality. Choose High quality or Dynamic profile, they increase the amplitude of sound by processing.
• 🔄 Resetting sound settings: In the same audio quality menu, click Reset settings. This will return factory equalizer settings that may have been changed by third-party apps.

If the volume hasn't changed after this manipulation, the problem goes deeper, maybe it's at the firmware level or the audio driver level, and then we go to more radical methods.

2. Turn off volume limit in developer settings

Manufacturers, including Xiaomi, often block the maximum volume through the EU (European Volume Limit) limiter, a standard designed to protect users' hearing, which can be turned off via the developer menu:

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. Return to the main settings menu and open a new section for developers (or additionally → for developers on some firmware).
3. Find the option Disable Absolute Volume and activate it, allowing the headphones to use their own amplifier instead of the MIUI constraints.
4. Find the Bluetooth Audio Codec below and select SBC or AAC instead of LDAC/aptX – these codecs sometimes turn down the volume to save energy.

Warning: After the EU limiter is turned off, the sound may become nonlinear at high frequencies (especially on cheap headphones).

💡

If the "Switch off absolute volume" option is not in your firmware, try updating MIUI to the latest version or using the method with the engineering menu (section 4).

3.Use equalizer and sound effects

The built-in MIUI equalizer allows you not only to adjust the frequencies, but also to increase the overall volume by compressing the dynamic range.

• 🎛️ Open the Settings. → Sound and vibration → equalizer.
• Choose a Bass or Rock preset – they automatically raise low and medium frequencies, which subjectively increases the volume.
• 🔧 Manually lift sliders at 100Hz, 250Hz and 1kHz per +3…+5 dB. Do not increase the high frequencies (8-16 kHz) – this will lead to distortion.
• 🔊 Turn on Adaptive Sound (if any) – it dynamically adjusts volume depending on ambient noise.

For more flexible customization, install a third-party equalizer, such as Wavelet or Poweramp Equalizer.

• Increase pre-amp to +6 dB.
• Use a compressor that “aligns” quiet and loud sounds.
• Use virtual surround to create a surround sound effect.

Set up a preset of "Bas" or "Rock"|Raise 100-250 Hz by +4 dB|Keep high frequencies unchanged|Enable adaptive sound (if available)|Turn off the normalization of volume in the player-->

4. Engineering menu: hidden audio settings

If standard methods don't work, it's time to look at the Engineering Mode, where you can remove the hardware volume limits, but be careful: improper changes can damage the speakers or microphone.

Instructions for Xiaomi:

1. Open the Phone app and type in the combination: ##36446337## (some models run ##4636## → Hardware Testing → Audio).
2. From the Hardware Testing menu, select Audio → Headset Mode.
3. Check the current Max Vol values (usually 80-100). Try to increase them by 10-15 units, but not above 120!
4. Press Set and restart the phone.

⚠️ Warning: Changing the Speaker Max Vol settings can cause physical damage to the membrane. Never raise this value above the factory's!

5. Install custom software or patch for audio

If your Xiaomi is running on an unlocked bootloader, you can install modified audio drivers or firmware with advanced audio settings.

• 🔧 Magisk modules: - ViPER4Android FX — A powerful sound processor with compressor and amplifier. - Audio Modification Library - increases the maximum volume by 20-30%. - JamesDSP - improves sound quality and removes restrictions.
• 📱 Brush firmware: - Pixel Experience or LineageOS often have less aggressive sound limitations. MIUI EU (For example, xiaomi.eu allows you to disable the limiter EU via settings.

The installation will require:

1. Unlock the bootloader through the Mi Unlock Tool (the official way from Xiaomi).
2. Install custom recovery (TWRP or OrangeFox)
3. Switch the selected module or firmware.

⚠️ Attention: Installing custom software resets the warranty and can lead to a device blink if you make an error. TWRP → Backup!

6. Check the headphones and the jack

Sometimes the problem isn't with the phone, it's with the hardware.

• 🔌 Connector pollution: Blow the 3.5mm connector or USB-C Compressed air. Oxidation of contacts can turn down the volume. Use a cotton swab soaked in isopropyl alcohol to clean.
• 🎧 Headphone resistance: Headphones with impedance above 32 ohms (e.g. Beyerdynamic) DT The 770 Pros require more power. Xiaomi may not rock them without an external amp.
• 🔋 Bluetooth codecs: For wireless headphones, open Settings → Connected devices → Settings gear next to the headphones and select the codec AAC or SBC instead LDAC (The last eats volume for quality).

If you use a USB-C → 3.5mm adapter, try connecting the headphones directly to another device. Cheap adapters often have a weak built-in DAC that limits power.

💡

Before buying new headphones, check their impedance: for smartphones, 16-32 Ohms are optimal. Models with a resistance of 100+ Ohms will require an external amplifier.

7. Third-party applications for sound amplification

If you don't want to go through the settings, you can use specialized applications that run on top of the system audio driver and amplify the signal software.

How to use amplifiers correctly:

1. Install the app from Google Play (avoid third party sites!).
2. In the app settings, find the Boost Volume or Pre-Amp option and raise it by 10-15%.
3. Turn off the built-in MIUI equalizer to avoid conflict.
4. Check the sound on different tracks – some apps only amplify certain frequencies.
