How to increase the volume of wireless headphones on Xiaomi Redmi: from MIUI settings to engineering menu

Xiaomi Redmi wireless headphones are a popular choice due to the combination of price and quality, but many users face the problem of insufficient volume. Even at the maximum level, the sound can seem quiet, especially in noisy environments or when listening to music at low frequencies, the reasons for this lie both in the limitations of the MIUI firmware and in the hardware features of the headphones themselves.

In this article, we’ll look at 7 working ways to turn up the volume on Redmi AirDots, Redmi Buds and other models, from basic smartphone settings to hidden engineering menu features. It’s important to understand that some methods can affect sound quality or speaker life, so we’ll explain the risks in detail and give you recommendations for safe use. If you’re willing to experiment, let’s go!

1. Check basic volume settings on Xiaomi Redmi

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

The first thing to do is check the individual volume settings for each type of content:

1. Open the Settings. → Sound and vibration.
2. Click on Volume (or swipe down the notification bar and tap the volume icon).
3. Make sure that Media, Calls and Alarms sliders are set to maximum.

Bluetooth devices

If the sliders are already at their maximum, but the sound is still quiet, try:

• 🔄 Reconnect the headphones: Turn them off in Bluetooth settings, then plug them back in again.
• 📱 Reboot your smartphone: sometimes system failures affect the output of sound.
• 🎧 Test the headphones on another device (such as a PC or other phone) to rule out hardware malfunction.

⚠️ Note: If the headphones sound louder on another device, the problem may be the limitations of Xiaomi’s firmware.

2. Turning off volume limits in MIUI (without root)

MIUI firmware sets volume limits by default to protect the user's hearing, and these restrictions can be removed without superuser rights using hidden settings.

Instructions for Xiaomi Redmi on MIUI 12/13/14:

1. Open the Settings app.
2. Go to About Phone and tap 7 times on the MIUI version line to activate the developer mode.
3. Return to the main settings menu and open Additional → for developers.
4. Find the option to turn off the absolute volume level (or Disable Absolute Volume) and activate it.
5. Also enable USB debugging (you will need for the following methods).

After that, reconnect the headphones - the volume should increase by 10-20%.

If you don’t have Disable Absolute Volume, try the alternative option via the engineering menu:

1. Open the Phone app and enter the combination: ##36446337###.
2. From the EngineerMode menu, go to Hardware Testing → Audio.
3. Select Headset Mode (or Bluetooth Mode for wireless headphones).
4. Set Max Vol to 160 (usually 140-150 by default).

⚠️ Warning: Changing the parameters in the engineering menu can cause sound distortion or overheating of the speakers. Do not set the value above 160 - this can cause the headphones to fail.

3.Use of third-party applications to amplify sound

If standard settings don't work, Google Play apps will come to the rescue, allowing you to bypass system constraints and increase volume through software-based audio processing.

Top.-3 Proven applications for Xiaomi Redmi:

How to use the Volume Booster:

• 📥 Install the app from Google Play.
• 🔊 Run it and move the slider 120-150 percent (above is the risk of distortion).
• 🎧 Connect your headphones and check the sound.
• ⚙️ In the application settings, turn off Notifications so that they do not interfere with.

Important: Some apps (like Spotify or YouTube Music) have their own volume limits, in which case it will help to turn off the sound normalization in the player settings.

4. Equalizer adjustment to improve volume perception

Sometimes the problem is not the volume itself, but the wrong frequency balance. For example, if the headphones are weakly listening to low frequencies (bass), the sound seems quieter.

How to set up the built-in equalizer in MIUI:

1. Open Settings → Sound and vibration → Equator.
2. Choose a Bass or Rock preset (they amplify low frequencies).
3. If you need to adjust more accurately, select Custom and lift the sliders to 60 Hz and 250 Hz.

For the Redmi Buds 4 Pro and other LDAC-enabled models, also enable this codec in Bluetooth settings – it delivers sound with less loss.

Advice for setting up:

• 🎛️ Don’t raise all frequencies at the same time – it will create a porridge effect in the sound.
• 🔊 For speech content (podcasts, audiobooks) increase the average frequencies (1-4 kHz).
• 🎵 For bass music (hip-hop, electronic music) accent 60-150 Hz.

Critical: On Redmi AirDots S and Redmi Buds 3 Lite, the built-in MIUI equalizer may not work with Bluetooth devices, in which case use third-party applications such as Wavelet (with Bluetooth support).

💡

Before setting up the equalizer, listen to the original track unchanged to understand what frequencies are missing.

5. Update of the firmware of headphones and smartphone

Low volume can be due to outdated firmware on headphones or smartphones. Manufacturers regularly release updates that fix sound bugs.

How to Update Redmi's Firmware Buds/AirDots:

1. Make sure the headphones are connected to the smartphone.
2. Open the Mi Home or Xiaomi Wear app (depending on the model).
3. Find your headphones in the list of devices and check for updates in the firmware section.
4. If the update is available, connect the headphones to the charging case and wait for the process to be completed (don’t turn off Bluetooth!).

For the smartphone:

• 📱 Go to Settings. → The phone. → Updating the system.
• 🔄 Click Check Updates and install the latest version. MIUI.
• 🔋 Make sure your battery is above 50% to avoid crashes.

After the update:

• 🔊 Check the volume – often new firmware versions remove the restrictions.
• 🎧 Reset the headphone settings (press the button on the case for 10 seconds) if the sound has not changed.

⚠️ Note: If after updating the firmware headphones stopped connecting, reset to factory settings via Bluetooth Settings → ⚙️ → Forget the device, then plug them back in.

Hardware methods: cleaning headphones and replacing pads

If the software didn't work, the problem could be in the physical condition of the headphones, and the dust, the earwax, the worn out earbuds, reduce the sound quality and create a muted effect.

How to Clean Redmi AirDots:

• 🧹 Use a soft brush (for example, for the camera lens) or a cotton swab soaked in alcohol to remove dirt from the speakers.
• 💧 Do not use liquids – they can damage the membrane.
• 🔍 Check the microphone holes (if any) - they can clog too.

For models with active noise cancellation (for example, Redmi Buds 4 Active), cleaning should be carried out every 2-3 months.

If the headphones are inserted, try changing the earbuds:

• 🎧 Buy foam pads (for example, Comply Foam) – they better isolate external noise, making the sound seem louder.
• 🔄 Choose a size that fits tightly to the ear canal (usually included in the kit are available). S/M/L).

Also check:

• 🔋 Case and headphone charge - with a low charge, the volume can automatically decrease.
• 📶 Distance to smartphone – if you are far from the device, Bluetooth communication weakens and the sound becomes quieter.

7. Radical methods: engineering menu and firmware modification

If none of the above has worked, there are advanced methods that require caution, which are suitable for power users and can lead to a loss of warranty.

Method 1: Change of parameters in the engineering menu (MTK)

For smartphones running MediaTek processors (e.g. Redmi 9A, Redmi 10C):

1. Enter the dialer: ##36446337##.
2. Go to Hardware Testing → Audio → Normal Mode.
3. Find the Max Vol and Min Vol settings for Headset and set: Max Vol: 160 Min Vol: 0
4. Save the settings and restart the phone.

Method 2: Installation of a custom core (requires root)

For advanced users who are ready to get root access:

• 📱 Install Magisk and module ViPER4Android.
• 🔊 In the settings ViPER4Android Activate Master Limiter and install Gain on the +3–6 dB.
• ⚠️ Be careful – incorrect settings can damage speakers!

⚠️ Warning: Modifying system files or firmware can cause a device to blink (completely inoperable).Before experimenting, back up via Settings → Additionally. → Backup.

💡

Engineering menus and custom firmware are extreme measures. Before using them, exhaust all other methods, as they can disrupt the stability of the device.
