How to increase the volume in Xiaomi Redmi wireless headphones: from settings to firmware

Xiaomi Redmi wireless headphones are some of the most popular gadgets in the segment, but many users face the problem of insufficient volume. Even at maximum settings, the sound can seem quiet, especially in noisy environments or when listening to music with deep bass. In this article, we will understand why this happens and how to safely increase the volume without risking damage to the speakers or losing the warranty.

The reasons for low volume can range from software constraints in the firmware to the hardware features of a particular model. It is important to understand that not all methods are equally safe. For example, changing system files can cause failures, and physical modification of headphones can lead to loss of warranty. We will focus on proven methods that work on most models of Redmi AirDots, Redmi Buds and other wireless headphones of the brand.

Before you start settings, make sure that the problem is not in the source of the sound. Check the volume on the smartphone itself, in the player app and on other devices (for example, connect your headphones to your laptop). If the sound is quiet everywhere - the problem is in the headphones. If only on your smartphone - look for a solution in its settings.

1. Checking the basic settings: what you might have missed

Start with the obvious, check the current volume settings, and users often overlook simple parameters that can limit sound.

• 📱 Media volume on your smartphone: Make sure the volume slider in the notification panel (or through the volume buttons) is set to maximum. MIUI There are separate regulators for multimedia, calls and alarms.
• 🎧 Volume on the headphones themselves: On touch-controlled models (like the Redmi Buds 4 Pro), check if your gesture settings are lost. Double-touch can adjust volume rather than playback.
• 🔊 "Do Not Disturb" Mode: In Settings → Turn off all restrictions, including night or quiet mode. Sometimes they are reset after updates.
• 🔄 Resetting headphone settings: Press the button on the headphone case (or touchpad) for 10-15 seconds until the indicator blinks. This will reset all user settings to the factory.

Pay special attention to the limitations EU-Firmware versions: Devices sold in Europe often have a software volume limit due to local regulations (directive) EU If your smartphone is purchased in the EU, this limit can apply to connected headphones. Check this in Settings → Additionally. → Regional settings.

⚠️ Note: Redmi AirDots 2 and Redmi Buds 3 Lite may reset the sound profile after updating the firmware. If the volume suddenly dropped for no apparent reason, try reconnecting the headphones to your smartphone again.

2. Equalizer and sound effects setup in MIUI

MIUI has built-in audio enhancement tools that many users don't use, and a properly tuned equalizer can not only increase the volume, but also make the sound clearer. Here's how to do this:

1. Open the settings → Sound → Equator.
2. Choose a preset called Bass or Rock, which usually amplifies the low and medium frequencies, which subjectively makes the sound louder.
3. If you need a precise setup, switch to the "User" mode and raise the sliders to 100 Hz, 250 Hz and 1 kHz for 2-3 divisions.
4. Activate the option “Adaptive sound” (if any) – it automatically adjusts the volume to the surrounding noise.

For headphone models that support LDAC or AAC (like Redmi Buds 4 Pro), also check the codec in Bluetooth settings:

• 🔗 Go to Settings. → Connected devices → Headphones → Sound settings.
• 🎵 Select "Sound Quality" and set it "LDAC" (if available, or "AAC" for better sound transmission.

If the built-in equalizer seems weak, install a third-party app like Wavelet or Poweramp Equalizer, which offer more flexible settings and can increase volume by adjusting the frequency response.

💡

In the Wavelet app, enable the option “AutoEQ” and select the model of your headphones from the database – this will automatically apply the optimal equalizer settings.

3. Update of the firmware of headphones and smartphone

The manufacturer regularly releases updates for Xiaomi's wireless headphones, which can improve sound, fix volume bugs or add new features.

• 📲 On a smartphone: Settings → The phone. → Updating the system.
• 🎧 For headphones: use the official Mi Earphones app (download to Google Play or AppGallery) and it has a section called "Firmware Update".

If there are no updates, but the volume is still low, try rolling back the firmware (if the sound was better before).

1. Remove the headphones from the list of associated devices.
2. Reset them to factory settings (press the button for 10-15 seconds).
3. Reconnect and check the volume.

On some models (e.g. Redmi AirDots 3 Pro), a hidden developer menu for sound may appear after the firmware update.

1. Connect the headphones to the smartphone.


2. Open the Mi Earphones app.




3. 5 times quickly click on the firmware version in the "About the device" section.

There may be additional volume settings in this menu, but you should change them carefully - incorrect parameters can lead to a distortion of the sound.

⚠️ Warning: Headphones with firmware version 1.4.0.6 and below have a bug that resets user equalizer settings after the update. Before updating, take screenshots of the current settings.

4.Use of third-party applications to amplify sound

If embedded facilities MIUI They don't help, you can use third-party utilities, they work at the system level, and they can bypass some of the limitations.-3 tested applications:

The easiest option is the Volume Booster.

1. Open the app and give access to the sound settings.
2. Activate the "Enhance Media" option.
3. Set the slider to 120-130 percent (higher is the risk of distortion).
4. Reboot your smartphone.

For ViPER4Android, you will need additional configuration:

Install APK and drivers | Activate in sound settings | Select "Extreme Bass" | Disable other equalizers |Reboot device-->

On headphones Redmi Buds 4 Pro when using ViPER4Android with a profile "Clear Bass" volume increases by 18-22% without noticeable distortion (tested on MIUI 14).

5. Modification of system files (for advanced users)

If the software methods didn't work, you can try changing the system files responsible for limiting volume, which is only suitable for users with unlocked bootloader and root rights.

The main files that regulate the volume in MIUI:

• /system/vendor/etc/audio_effects.conf — sound effects settings;
• /system/vendor/etc/mixer_paths.xml — sound routes and limitations;
• /system/vendor/etc/audio_policy_configuration.xml — volume-politics.

To change the parameters:

1. Download Root Explorer or FX File Explorer.
2. Cross the path. /system/vendor/etc/ and find the file. mixer_paths.xml.
3. Make a backup copy of it.
4. Open the file in the text editor and find the lines with max_volume.
5. Increase the values by 20–30% (for example, from 80 to 100).
6. Save the file and restart the smartphone.

For Redmi AirDots headphones 3 The critical parameter is bluetooth_headset_volume. It can be increased to 15 (standard — 10). After the changes, check the sound on different tracks – if wheezing appears, reduce the value.

⚠️ Attention: On devices with MIUI 13+ post-refresh OTA All changes to system files are reset. To avoid this, use the Magisk module to protect files from overwriting.

6 Hardware methods: when software does not help

If none of the software methods worked, the problem could be in the hardware.

• 🔧 Clean speakers: Dust and dirt can drown out sound. Carefully clean the speaker grid with a soft brush or compressed air (do not use sharp objects!).
• 🔋 Battery check: Headphones with discharged battery automatically turn down the volume. If they sit down quickly, replace the battery (at the service center).
• 🔊 Membrane replacement speaker: When physically damaged (for example, after falling), the membrane can deform, resulting in a quiet sound.
• 📡 Bluetooth module check: If the sound is quiet only when connected to a particular device, the problem may be in the smartphone’s antenna or Bluetooth chip.

To diagnose hardware problems, connect your headphones to another device (like a laptop or tablet). If the sound is quiet, the problem is with the headphones. If it becomes normal, look for the reason in your smartphone.

Redmi Buds 3 Pro and older have a built-in speaker test to run it:

1. Connect the headphones to your smartphone.
2. Open the Mi Earphones app.
3. Go to Settings → Diagnostic → Sound test.
4. Follow the instructions on the screen.

If the test shows an error, contact the service center. Self-repair of headphones without experience can lead to their final breakdown.

7. Alternative solutions: when nothing helps

If all methods have been tried, but the volume still doesn’t suit, consider alternative options:

• 🎧 Buying headphones with support ANC: Active noise cancelling models (like the Redmi Buds 4 Active) are better at isolating external sounds, so they seem to play louder.
• 🔊 Use of external amplifier: Bluetooth amplifiers (e.g. FiiO) BTR3) They can increase the volume without distortion.
• 📱 Smartphone Change: On some devices (e.g, POCO F4) Volume limits are less stringent than on the Redmi Note.
• 🎵 Change the formats of audio files: Convert music to FLAC or WAV — They have a greater dynamic range than MP3.

If you’re buying new headphones, look for models that support aptX Adaptive or LDHC — they deliver less lossy audio, which subjectively increases volume. Among Xiaomi, these are:

• Xiaomi FlipBuds Pro (aptX Adaptive);
• Redmi Buds 4 Pro (LDHC);
• Xiaomi Buds 4 (AAC with improved encoding)

Before buying, check the reviews about the volume of a particular model – some users share measurements of the sound level in decibels.

💡

Headphones with LDHC support (e.g. Redmi Buds 4 Pro) can sound 10-15% louder due to a more efficient codec, even if the hardware stuffing is identical to the models with AAC.
