How to turn up the volume on Xiaomi headphones: the full guide

Modern wireless headphones from Xiaomi and Redmi are often pleasing with design and autonomy, but sometimes users are faced with a situation where the maximum sound level seems insufficient. This is especially noticeable in noisy places, such as the subway or the street in windy weather. The insufficient volume can be caused by the software limitations of the operating system, Bluetooth codec settings, or simply the features of a particular headset model.

Before you panic and take your device to the service center, you should check a number of software settings that are often ignored. There are several levels of audio adjustment in the Android ecosystem and the MIUI or HyperOS shell, and sometimes they conflict with each other, and the signal level is also affected by the connection quality and version of the Bluetooth drivers.

In this article, we will look at all possible solutions, from basic checks to advanced engineering menu tuning techniques, how to activate absolute volume, adjust the equalizer to amplify high frequencies, and what applications can help bypass system limits. Follow the instructions carefully to safely increase the sound level without losing its quality.

Basic verification of hardware buttons and pairing

The first step should always be to check the physical condition of the device and the correct pairing. Often the problem lies not in the software failure, but in desynchronizing the volume levels between the smartphone and the headset. Make sure that you use the original charging cable (if the headphones are wired or require charging to activate) and that the contacts are clean.

Try re-pairing: remove the device from the Bluetooth list on the phone, put the headphones in the case, close it, then open it and reconnect. This action resets temporary connection profiles. Reconnect often solves the problem if the data protocol was installed with an error.

Pay attention to the control buttons on the headphones themselves or the touch zones. In some models, such as the Xiaomi Mi True Wireless Earbuds Basic 2, long pressing or double tapping can adjust the volume, but by default there is track management. Check the instructions for your particular model.

• 🔍 Make sure that Bluetooth settings include Multimedia, not just Phone Sound".
• 🔌 Check battery power: at low charge levels, some models automatically limit speaker power.
• 🔄 Reboot your smartphone to reset Bluetooth services and audio drivers.
• 🧹 Clean the speaker mesh of earwax that can physically drown out sound.

⚠️ Attention: If after reconnecting the sound became quieter, but there was a crack, perhaps a problem in the hardware of the speaker or moisture.

Setting the absolute volume in Android

One of the most common causes of silent sound is the desynchronization of volume sliders. In Android, there's a "Absolute Volume" feature that links the sound level of the phone and the headphones into a single control loop, so if this function is not working correctly, the phone may think it's spinning 100% of the sound and the headphones are turning 50% of the signal.

To fix this, you need to go to the developer menu. The path usually looks like this: Settings. → The phone. → Press 7 times on "Version" MIUI". After the inscription "You became a developer" we move to the → For developers, you need to find the item "Offline absolute volume".

If the switch is active, try to change its state. If it was turned on, turn it off, and vice versa. Once you change the setting, be sure to restart the device. This method is especially effective for Redmi Buds 3 Pro and AirDots models, which sometimes conflict with new versions of Android.

It is worth noting that on some versions of HyperOS, this item may be called differently or hidden, in which case you can use the search by settings by entering the "absolute" query.

Use of equalizer and sound effects MIUI

Xiaomi’s built-in sound processing tools offer powerful tools to amplify the signal. The standard equalizer allows you not only to adjust the frequencies, but also to increase the overall volume by amplifying certain ranges. Go to Settings → Sound and vibration → Sound effects.

Here you will find a graphical equalizer. To increase the volume, it is recommended to raise all sliders up, creating a flat line at the top of the graph, or select a preset "Rock" or "Pop" profile, which usually have a more aggressive setting. Also activate the Mi Sound Enhancer effect, if it is available for your model.

Special attention should be paid to the "Advanced Sound" feature, which is called "Audio Effects" in some regions. The option "Adaptive Sound" can automatically adjust frequencies to the shape of the ear canal (calibration is required), which subjectively increases the volume and clarity.

💡

Use the Rock profile in the equalizer even for listening to podcasts – it often gives the maximum volume increase by raising the average frequencies.

Boost apps and third-party software

If you don't have enough system settings, Google Play's specialized apps come to the rescue, and they act as an intermediate layer that amplifies the audio stream before being sent to a Bluetooth module, and the leader in this niche is the Volume Booster GOODEV app, which allows you to exceed the standard limit of 100%.

Another powerful tool is Precise Volume. This app allows you to create profiles for different devices. You can set up a profile specifically for your Xiaomi Buds. 4, reinforce 20-30% It's important not to overdo it, because it can lead to wheezing.

There are also apps with their own codecs, like Poweramp Equalizer, which require finer tuning but give you better control over sound quality. When using third-party software, make sure the app has the necessary permissions to access the microphone and system audio settings.

⚠️ Attention: Installation of gain above 20-30% in third-party applications can lead to irreversible damage to the headphone speakers due to overloading the membrane.

Remember that using such programs increases the battery consumption of the smartphone, as the processor processes the audio stream more actively. To save energy, turn off boosters when they are not urgently needed.

Secrets of the engineering menu and hidden settings

For advanced users, there is an engineering menu where you can change the maximum volume level at the driver level, and you can log in via a set of code in the phone book, for example, ##6484## (code may vary depending on the model and region), and you can find the Audio or Speaker section in the menu.

You can find Gain settings for different scenarios: Headset, Bluetooth, Media. Increasing the value in these fields raises the volume ceiling. However, changing the values in the engineering menu carries a high risk: incorrect settings can lead to complete absence of sound or the need to flash the device.

Alternative safe method - use of ADB-When you connect the phone to your computer, you can type a command that turns off the volume limit for Bluetooth:

adb shell settings put global absolute_volume_enabled 1

This method is less risky than direct register editing in the engineering menu, but requires a PC and installed ADB drivers. Before any manipulations, it is recommended to make a full backup of data.

Optimization of Bluetooth codecs

The sound quality and volume are directly dependent on the data codec used. Xiaomi supports various codecs: SBC, AAC, aptX, LDAC. SBC codec is basic and often gives the lowest volume and quality. Codecs like aptX Adaptive or LDAC transmit more data, which can positively affect the perception of volume.

You can check and change the codec from the developer menu. Find the Bluetooth Codec and choose the best quality one available for your headset. If the headphones support LDAC, be sure to switch to it. You should also experiment with bitrate in the LDAC settings by selecting Sound Quality Priority.

Sometimes it helps to disable the option "LDAC: Adaptive connection" if the signal is unstable. Forced selection of high bitrate can stabilize the flow of data by eliminating micro-gaps that are perceived as silence or volume reduction.

• 🎧 SBC — Basic codec, minimum quality.
• 🎵 AAC — Apple standard, good quality on Xiaomi.
• 🚀 aptX / aptX HD — High quality and low latency.
• 🔥 LDAC — Maximum quality but higher battery consumption.
