How to Add Volume to Xiaomi Headphones: Expert Guide

Xiaomi’s current wireless headphones, whether popular Redmi Buds or flagship Mi True Wireless, often delight users with build quality and autonomy. However, many owners face the problem when standard sound levels are not enough to comfortably listen to music in noisy vehicles or on the street.

Device owners often wonder why Xiaomi's smartphone has a high-speed audio spin, but still seems quiet in headphones. The answer lies in deep system settings that are hidden by default from the user. Unlocking the full potential of the audio system requires a series of sequential actions, which we will discuss in detail in this material.

In this article, we're not just going to look at standard volume sliders, but we're going to go into the engineering menu and the developer's system flags, and you're going to learn to bypass software limits that artificially lower the output level to get the clearest and loudest possible sound.

Basic volume setting through the system menu

The first thing to do before making complex changes is to make sure that all the basic volume levels are maxed out. In the MIUI shell (now HyperOS), the sound control is divided into several independent channels: media, alarm, call and notifications. Often users only raise the volume of the call, forgetting about the multimedia track.

To access the advanced adjustment menu, press the physical volume button on the smartphone body. Once the slider appears on the screen, tap the three-point icon or gear to deploy the full mixer. Here you will see separate scales for each type of sound. Make sure that the Media slider is raised to the right.

Also worth checking your Bluetooth device settings. Go to Settings → Bluetooth, find your connected Xiaomi headphones in the list, and click on the gear icon next to them. The menu that opens can have a separate volume slider that syncs or works independently of the system. If there is one, it also needs to be twisted to the maximum.

It is important to note that some headphone models have their own control logic. For example, double touching on the sensor can adjust the volume of the track, rather than switching songs. Check the gesture settings in the Xiaomi Earbuds or Mi Buds M8 app to make sure the sound control is set up correctly.

• 🎧 Press the volume button and select "three dots" to access the full sound mixer.
• 🔊 Make sure that the Media channel is 100% unscrewed, not just the Call».
• 📱 Check the settings of a specific Bluetooth device in the pairing menu.
• 👆 Set up touch control in the branded headphone app.

💡

Check whether Quiet or Do Not Disturb is enabled in the notification curtain, as it can programmatically limit the maximum volume of notifications and media.

Activation of Bluetooth absolute volume

One of the most effective features for increasing sound is the option “Absolute Volume.” Android can default to not synchronize the volume levels of the phone and headphones, creating a “ceiling” that cannot be broken by standard methods.

To activate this option, you will need access to the developer menu. → About the phone and find the line "Version" MIUI» Or, "OS Version." Quickly click on this line 7 times in a row until the message "You're a developer" appears. Then a new option will appear in the main settings menu "Additional" or "Extended settings", where you need to select "Developers For Developers».

Inside the developer menu, scroll down to the "Network" or "Bluetooth" section. Find the "Disable absolute volume" item. Here's the important point: if the switch is off, the absolute volume works. If it's on, it's off. You need to get the volume of the phone and headphones to be the same. Experiment with the position of this switch: in some versions of Android, you need to turn it on, in others, turn it off to achieve the desired effect.

When you change the setting, be sure to reconnect the headphones. Turn off and turn on Bluetooth or pair again. Now, when you change the volume with the buttons on the phone, you should see how the indicator on the headphones themselves (if any), which indicates successful synchronization.

Use of System Equalizer and Dolby Atmos

Xiaomi smartphones are equipped with advanced audio modules that are often underestimated by users. Built-in equalizer and Dolby Atmos technology (if supported by the model) can not only improve sound quality, but also significantly add volume through software signal processing.

To access the equalizer, go to Settings → Sound and Vibration → Sound Effects. Here you will see a list of preset profiles: Pop, Rock, Jazz, etc. Choose a profile that matches your genre, or create a custom one. In manual mode, try to lift all the frequency sliders upwards, creating a smooth curve with a slight rise in the mid- and high-frequency areas, which subjectively adds brightness and volume to the sound.

Dolby Atmos is a feature that deserves special attention. If your smartphone supports this technology, include it in the same audio effects menu. Dolby Atmos not only makes the sound louder, it optimizes dynamic range, making quiet sounds more audible and louder ones clear. Headphones are often available special mode that expands the stereobe.

Also, the audio effects menu may include the option “Mi Sound” or “Enhanced headphones.” Activate it and select the type of headphones installed (for example, “Earbursers-in-ears” or “Plug-in-Hear”). The system will use a special correction algorithm adapted to the design of the speaker, which often leads to a noticeable increase in power.

💡

The combination of Dolby Atmos enabled and the manual equalizer setup gives the greatest increase in subjective volume without the use of third-party software.

Third-party sound amplifiers

If there's not enough system tools, specialized applications from the Google Play Store come to the rescue, and they work on the principle of Gain Boost, letting audio stream through their filter before sending it to a Bluetooth module, which allows you to exceed the standard Android restrictions.

One of the most popular and reliable solutions is the Volume Booster GOODEV app, which has a minimalist interface and no unnecessary features. After installation, simply move the Boost slider to the right. However, beware: values above 40-50% can lead to wheezing of the earphone speaker or even damage.

Another powerful tool is Bass Booster & Equalizer, a combines equalizer and amplifier, which allows you to adjust frequencies more flexibly than Xiaomi’s standard equalizer, and has a separate gain regulator (Pre-amp).

And the Super Volume Booster app, which automatically amplifies the sound when you start media players, is useful if you often forget to check your settings, but remember that using third-party amplifiers increases battery consumption, as the processor has to constantly process the audio stream.

⚠️ Attention: Using software amplifiers above 60% can cause permanent damage to the speaker membrane in the headphones.

• 🚀 Volume Booster GOODEV — Simple and effective amplifier with one slider.
• 🎛️ Bass Booster & Equalizer – a complete solution for adjusting frequencies and volume.
• 🔋 Remember that third-party boosters increase smartphone power consumption.
• 🎧 Start the amplification with small values so as not to spoil the dynamics.

Engineering menus and hidden codes

For advanced users, there is an engineering menu where you can change the audio output parameters at the driver level, which is the riskiest method, but also the most effective if the software constraints are too tight. In the engineering menu, you can increase the Gain for Bluetooth protocol.

To enter the engineering menu, open the Phone app and dial the code ##6484## or #4636##. Codes may vary depending on the version of MIUI and the CPU model (Snapdragon or MediaTek). If the code is not working, it is possible that access to the engineering menu is blocked by the operator or firmware.

In the test menu, select Speaker or Audio. You can find audio playback tests here. However, the real setting is often hidden in the Audio Debug submenus or requires you to switch to Engineer Mode via special applications like MTK Engineering Mode (for MediaTek processors). In the Volume section, you can find settings for Media and Headset. Increasing the values in these fields (for example, from 120 to 150) will raise the maximum volume threshold.

Be extremely careful: an unjustified increase can lead to digital distortion (clipping), when the sine wave of the audio signal is “cut off”, creating an unpleasant crack.

Popular codes for entering test modes:


##6484## — CIT (Hardware Test)
#4636## - Testing (Phone Information)
##3646633## — Engineer Mode (MediaTek)

⚠️ Warning: Change the parameters in the engineering menu is done at your own risk. Write down the initial values before making the changes so you can get it back.

Resolving problems with quiet sound

Sometimes the problem isn't the settings, but technical malfunctions or contamination. If Xiaomi headphones suddenly become quieter, even after all the settings, the first thing to do is check the speaker grid. Earwax and dust can clog holes, blocking up to 50% of the sound stream.

Carefully clean your headphones with a soft dry toothbrush or a special Velcro for cleaning equipment. Do not use sharp objects, as you can damage the membrane. Also check the battery power: some models of headphones at low charge automatically reduce the volume to save energy.

Another possible reason is to desynchronize the device, try a full Hard Reset, which is usually done by slamming the touch zones or a button on the case. 10-20 After reset, remove the device from the Bluetooth list on your phone and pair again.

If neither method helped, there may be a problem with the Bluetooth codec. On the developer menu (Settings → Developer → Bluetooth Codec), try changing the codec from AAC or SBC to aptX or LDAC (if supported by both devices). Higher quality codecs sometimes run more stable and louder, although they consume more traffic.
