How to add sound in headphones on Xiaomi: safe ways without harm to technology

You've connected your headphones to a Xiaomi smartphone, but the sound is too quiet? The problem is familiar to many owners of MIUI devices — even at maximum volume, music or video can barely be heard. The reasons can vary from the software limitations of the firmware to the hardware features of a particular model. In this article, we will discuss 5 proven ways to increase the volume in headphones without risking damage to the speakers or losing the warranty.

It is important to understand that Xiaomi artificially lowers the volume level in the headphones to protect the hearing of users (according to EU Volume Limit standards). However, these restrictions can be circumvented by legal methods - without root rights or dangerous modifications of the system. We tested all methods on the Redmi Note 12 Pro+, POCO F5 and Xiaomi 13T models, so the instructions are relevant for most devices on MIUI 14/15 and HyperOS.

If you use wireless headphones (such as Xiaomi Buds 4 Pro or Redmi AirDots 3), some of the methods will be different — we will talk about this in a separate section.

1. Check basic sound settings in MIUI

Before you resort to third-party solutions, make sure that the problem is not in the standard settings of the system.

• 🔊 Volume Controller: Press the physical volume button on the side panel of your smartphone and check that the Media slider (not Call!) is set to maximum. MIUI These regulators are divided.
• 🎧 Headphone Profile: Connect the Headphones and Open Settings → Sound and vibration → Headphones, there could be a separate volume control for accessories.
• 🔄 Adaptive sound: In the same audio settings, turn off the option Adaptive sound or Smart volume – it automatically lowers the level depending on the surrounding noise.

If the sound is still quiet after this manipulation, move on to the next step. Note: on some models (for example, Xiaomi 12S Ultra) there is a separate item in the headphone menu called Sound Amplifier - turn it on if it is available.

⚠️ Note: On HyperOS devices (e.g. Xiaomi 14), the path to headphone settings may be different: → Connected devices → [The name of your headphones. "" Sometimes there's an extra equalizer hidden here.

2.Using the built-in MIUI equalizer

The MIUI system equalizer allows you not only to adjust the sound, but also indirectly increase the volume by amplifying certain frequencies.

1. Open Settings → Sound and vibration → Equator.
2. Select the User Profile (or Custom in new versions).
3. Pull the 300 Hz and 1 kHz sliders up 3-4 divisions, which will increase the average frequencies where the main energy of voice and musical instruments is concentrated.
4. Save the preset under the name Max Volume.

This method doesn't increase the volume directly, but it makes the sound more dense and sharp, which is subjectively perceived as leveling up. For better effect, combine it with turning off Dolby Atmos (if it's on), which sometimes eats up dynamic range.

3. Disable volume limit in developer mode

MIUI has a setting that limits the maximum volume for headphones, and you can turn it off through the developer menu:

Turn on Settings → About Phone → MIUI Version (click 7 times)| Return to Settings → Additional → For Developers | Find the item Turn off the absolute volume (or Disable Absolute Volume) |Reboot the device-->

After restarting, check the volume, which can increase up to 15-20% on some models (such as the POCO X5 Pro), but the effect depends on the firmware version: in MIUI 14 and later, this option may not work.

If there is no absolute volume switch, try an alternative method:

adb shell settings put global volume_music_speaker_scale 1.5

This command must be typed in through ADB (the instructions for setting up the ADB for Xiaomi can be found in our separate article). 1.5 increases volume by 50% – experiment with values from 1.2 to 2.0, but do not exceed the last threshold to avoid distortion.

⚠️ Note: Change of system parameters through ADB This can cause audio drivers to crash. Before experimenting, back up your settings in Settings. → Additionally. → Backup.

4. Third-party applications for sound amplification

If system methods didn't work, look at specialized utilities. We tested 7 applications and selected 3 of the most effective ones:

For most users, the best choice is Volume Booster — it's easy to use and doesn't require root rights. Install an app, allow access to media files, and move the slider to the maximum. Note that some apps (like Spotify or YouTube Music) may block audio amplification due to their internal limitations.

💡

If the sound gets distorted after installing the booster, lower the gain to 70-80% and turn on the Limiter option in the app settings, which will remove the wheezing without losing volume.

5. Features of setting up Xiaomi wireless headphones

For Xiaomi Buds, Redmi AirDots and others TWS-There are separate rules for headphones. First, check the firmware version of the headphones:

1. Open the Mi Home or Xiaomi Wear app.
2. Find your headphones in the list of devices.
3. Go to Settings → Update firmware.

Outdated firmware can cause sound problems. For example, Xiaomi Buds 3 Pro before version 4.7.15 had a bug with an artificial volume limit of 60% from the maximum.

Second, use the branded app to fine-tune:

• 🎛️ In Mi Home, open the equalizer and select the preset Bass Boost - this will add "volume" to the sound.
• 🔇 Turn on the option Transparent Mode (if any) – it amplifies external sounds, which indirectly increases the perception of volume.
• 🔄 Turn off Adaptive Noise Cancelation – it can automatically turn down the volume.

6. Hardware causes of silent sound and their elimination

If the software methods do not work, the problem may lie in the "hardware":

• 🔌 Contaminated 3.5 mm connector: On models with audio connector (e.g., audio connector, POCO M5) Check it for dust or oxidation.
• 🔋 Weak headphone battery: Wireless headphones at low charge (less than 20%) automatically turn down the volume.
• 🎵 Damaged audio chip: If the sound is quiet in all applications and after resetting, the audio codec may have malfunctioned (e.g., Qualcomm) WCD9385 It's in Xiaomi's flagships.

To diagnose hardware problems, perform the test:

1. Connect your headphones to another device (PC, other smartphone), and if the sound is normal, the problem is in your smartphone.
2. Try other headphones with your Xiaomi. If they are quiet too, it's the firmware or hardware fault.

⚠️ Note: On Type-C models (without 3.5mm connector), the quiet sound may be associated with a non-original adapter. Use only certified Xiaomi or Google adapters - cheap counterparts often do not provide enough power to amplify the adapter.

💡

If a quiet sound appeared after a smartphone falls or moisture gets in, DO NOT try to amplify it programmatically - this can damage the speakers.

7. Alternative solutions: from Bluetooth codecs to custom firmware

For advanced users, there are radical methods:

• 🔄 Change of Bluetooth codec: In Settings → Connected devices → [Your headphones] → Select the audio codec by aptX or LDAC instead SBC. This will improve the sound quality and may add volume.
• 📱 Castom firmware: Firmware like Pixel Experience or LineageOS has no limitations MIUI However, this requires unlocking the bootloader and losing the warranty.
• 🔊 External DAC: USB-C DAC (e.g. Xiaomi) HD Audio Dongle bypasses the smartphone’s built-in audio track, giving a clean and loud sound.

Remember: installing custom firmware or modifying system files can lead to a ban on your Mi Account (if the device is tied to Xiaomi Cloud) or problems with your device. OTA-Use these methods only if you are prepared for the risks.

For owners of POCO F4 GT or Black Shark 5, there is a bonus: in game mode (Settings → Special Options → Game Turbo Mode), all sound restrictions are automatically turned off. Activate it even if you do not play - this will give you an increase in volume.
