How to increase the volume of Xiaomi headphones to the maximum: from software settings to firmware

Xiaomi headphones are among the most popular accessories due to the ratio of price to quality, but many users face the problem of insufficient volume. Even at maximum settings, the sound can appear quiet, especially in noisy conditions or when using models with passive noise cancellation, the reasons for this lie in both hardware limitations (weak speakers, resistance of the coils) and software - the manufacturer artificially lowers the volume to protect hearing.

In this article, we will discuss 7 working methods to increase the volume on Xiaomi headphones, from basic smartphone settings to deep firmware modifications. It is important to understand that some methods require root or specialized software rights, and improper actions can lead to damage to the device or loss of warranty. We will specify the risks for each method and give recommendations for security.

The material is relevant for all models of headphones brand: Mi True Wireless Earbuds, Redmi Buds, Xiaomi Hybrid, Mi ANC and wired options (for example, Mi Basic or Mi Dual Driver). Also provides universal tips for users of smartphones Xiaomi, Redmi and POCO based on MIUI.

1. Check the basic sound settings on the Xiaomi smartphone

Before you resort to radical measures, make sure the problem isn't with standard settings.There are a few hidden settings on Xiaomi smartphones that can limit volume.

Open Settings → Sound and vibration and do the following:

• 🔊 Turn off "Safe Volume Level" -- this feature automatically lowers volume after a long listening period. Switch the slider to "Off.".
• 🎧 Select the Music profile under Sound Modes – it usually gives more volume than Talk or Game".
• 🔄 Reset the sound settings (bottom of the page) – this will return all parameters to the factory if they were changed accidentally.
• 📱 Check individual app settings: Some players (such as Mi Music or Spotify) have their own volume controller.

If you use Bluetooth headphones, go to Settings → Bluetooth, find your device, and turn on the option “Absolute Volume” (if available).

2.Using uniform gain (EQ) in MIUI

The built-in equalizer in MIUI not only allows you to adjust the sound, but also slightly increase the volume by amplifying certain frequencies, which will not give a dramatic increase, but can make the sound more saturated.

How to set up:

1. Go to Settings → Sound and vibration → Equator.
2. Choose the preset Bass or Rock – they usually turn up the volume.
3. Manually lift the sliders 100 Hz and 1 kHz 2-3 divisions. Do not raise high frequencies (8-16 kHz) - this can cause distortion.
4. Save your settings as a new profile (e.g., Max Volume).

For more fine-tuning, use the Wavelet app (available on Google Play).It supports automatic calibration for specific Xiaomi headphone models and has an advanced limiter that prevents clipping (distortion) when the volume goes up.

💡

If the sound becomes hoarse after the change in EQ, reduce the amplification at frequencies above 5 kHz - this will eliminate high-frequency distortion.

3. Unlocking the engineering menu (for wired headphones)

Xiaomi smartphones have a hidden engineering menu where you can change hardware volume limits, which only works for wired headphones and requires caution – incorrect settings can damage speakers.

Instructions:

1. Open the Phone app and enter the code ##36446337## (or #4636## for older versions of MIUI).
2. Go to Hardware Testing → Audio → Headset Mode.
3. Find Max Vol or Headset Volume and increase the values by 2-3 units (usually a maximum of 160).
4. Save the changes and restart the smartphone.

⚠️ Warning: Increasing volume through the engineering menu can cause speakers to overheat and fail.Don't push the values above 160 - this is the limit for most Xiaomi models.

If the code doesn’t work, try an alternative method:

• Install the MTK Engineering Mode app (for MediaTek processors) or Qualcomm EngineerMode app (for Snapdragon).
• In the Audio section, find the settings for Headset and adjust Volume.

4. Modification of the file mixer_paths.xml (root)

For root-right users, there is a way to change the system volume limits by editing the file. mixer_paths.xml. This method gives the largest volume increase, but requires technical skills.

Step-by-step:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Cross the path: /system/vendor/etc/mixer_paths.xml (or /system/etc/mixer_paths.xml old-device).
3. Make a backup of the file!
4. Open the file in the text editor and find the lines with the parameters: <path name="headphones"> <ctl name="HPHL Volume" value="60" /> <ctl name="HPHR Volume" value="60" /> Increase the value to 80-90 (no higher!).
5. Save the file, set the rights to 644 (rw-r--r---) and restart the device.

⚠️ Attention: Incorrect editing mixer_paths.xml It can cause loss of sound or looping of the bootloop. Check your smartphone model before changing it - the paths to the file may differ!

5. firmware of the custom core or modified MIUI

For power users, the most effective way to increase volume is to install a custom core (such as FrancoKernel or ElementalX) or firmware with modified audio drivers. This method requires an unlocked bootloader and TWRP.

Popular Firmware with Improved Sound:

• 🔧 Pixel Experience – contains Google’s audio drivers with advanced settings.
• 🎵 ViPER4Android — requires separate installation via Magisk, but gives a powerful equalizer and amplifier.
• 📱 MIUI EU — European version of firmware without volume restrictions.

Instructions for installation of ViPER4Android:

1. Install Magisk and ViPER4Android FX module through it.
2. Download drivers for your smartphone model (e.g. V4A Compatibility Patch).
3. In the settings of ViPER4Android activate: Amplifier → Headphones → Gain: +6 dB Limiter → Disable
4. Reset the device.

After installing the custom core, the volume can increase by 20-30%, but be prepared for possible bugs (for example, increased battery consumption or audio distortion at high frequencies).

Hardware methods: signal amplification and speaker replacement

If the software fails, the problem may be the hardware of the headphones, such as cheap Xiaomi models (such as the Mi Basic) using speakers with high resistance (32 Ohms), which require more power for normal volume.

Options for a solution:

• 🔌 Use an external amplifier (e.g. FiiO) A1 Xiaomi USB-C Amplifier. It increases signal power and improves sound.
• 🔧 Replace the speakers with a lower resistance (16-24 ohms) suitable for wired headphones but requires soldering.
• 🔋 Check the cable, often the problem is in a damaged wire or contacts. Try cleaning the 3.5mm connector with alcohol.

For Bluetooth headphones (such as Redmi Buds 3 Pro), a weak codec signal may be the cause of quiet sound. In Bluetooth settings, select the codecs in this priority order:

1. aptX HD (maximum quality, but not all models support)
2. AAC (Optimum balance of quality and volume)
3. SBC (most compatible, but quietest)

⚠️ Note: Replacing the speakers in Xiaomi headphones voids the warranty. If you are not sure about your soldering skills, contact the service center. The cost of repairs usually does not exceed 500-1000 rubles.

7. Alternative applications for sound amplification

If you don't want to interfere with system files, try third-party applications to amplify the volume. They work as an intermediate layer between the player and the headphones, increasing the amplitude of the signal.

Top.-3 apps:

How to use the Volume Booster:

1. Download the app from Google Play.
2. Activate the "Hearphone Amplifier" option.
3. Set the slider to 120-130 percent (higher is the risk of distortion).
4. Turn on the music and check the sound.

The downside of these applications is that they consume an additional battery (up to 5-10%) and may conflict with system sound drivers. If there is stuttering or noise after installation, turn off the amplifier.

💡

Third-party applications to amplify sound do not increase the actual power of the speakers, they only amplify the signal, which can lead to distortion. For best results, combine them with hardware methods (for example, an external amplifier).
