Xiaomiβs Bluetooth headsets are some of the most popular on the market, thanks to a combination of price, quality and functionality. However, many users face a problem: even at maximum volume, the sound in Xiaomi AirDots, Redmi Buds or Mi True Wireless headphones seems quiet. This may be due to firmware limitations, codec features or the settings of the smartphone itself.
In this article, weβll look at 7 proven ways to increase the volume of a Bluetooth headset, from standard MIUI settings to hidden developer settings and third-party apps. Itβs important to understand that some techniques can affect sound quality or speaker life, so use them with caution. If you hear distortions at maximum volume, check the headphones on another device first β perhaps the problem is in the hardware.
We will proceed to a detailed analysis of each method, starting with the safest and ending with advanced tricks for experienced users.
1. Check basic volume settings on a smartphone
Before you resort to radical measures, make sure that the problem is not the basic settings. On Xiaomi devices with MIUI firmware, the volume for Bluetooth devices is adjusted separately from the main sound.
Open the Quick Settings Panel (swipe down from the top edge of the screen) and find the volume slider. Tap the "Cog" icon next to it, and a menu with separate regulators will open for:
- π Calls (turns on the volume of the headset during a conversation)
- π΅ Media (music, video, games)
- π Notifications and alarm clocks
Make sure the Media slider (or Bluetooth, if any) is set to maximum, and check if the Do Not Disturb mode (Settings β Sound and Vibration β Do Not Disturb) is activated, which can automatically turn down the volume.

If the volume is reset after connecting the headset, try turning off the Adaptive Sound function in the Bluetooth device settings (if any).
2. Set up an equalizer in the Music or Mi Sound Enhancer app
MIUI has an integrated equalizer that can artificially amplify low and high frequencies to create a higher volume effect.
Settings β Sound and vibration β Equalizer or Settings β Additional β Mi Sound Enhancer
Choose a preset called Bass or Rock, which amplifies the low frequencies, which subjectively makes the sound louder. If you don't have the desired effect, create a custom profile:
- ποΈ Increase sliders by 60Hz and 250Hz (bass)
- ποΈ Increase 1 kHz to 4 kHz (medium frequencies, responsible for vocals)
- π« Donβt push 16 kHz β it will lead to distortions
After setting up, turn on the option βApply to all applicationsβ so that the equalizer works not only in the player, but also in messengers, games, etc. Please note: excessive bass amplification can lead to wheezing at high volume.
3. Activation of the developer mode and changing hidden parameters
If standard methods donβt work, you can try changing the hidden Android settings that control Bluetooth volume.
- Activate Developer Mode: Go to Settings β About Phone and 7 times click on the MIUI Version. a notification will appear βYou became a developerβ.
- Open the settings β Additional β for developers.
- Find the option to turn off the absolute volume of Bluetooth (Disable Absolute Volume) and turn it on.
- Restart your smartphone and check the volume.
This setting disables the synchronization of the volume level between the smartphone and the headset, allowing the devices to work at their maximum values. However, once activated, the volume adjustment may not work correctly - for example, when the level on the phone changes, the sound in the headphones will remain the same.
What if there is no "disable absolute volume" item?
4.Use of third-party applications to amplify sound
If the built-in tools don't work, Google Play apps will come to the rescue, and we tested a few and selected the most effective ones:
| Annex | Functions | Pluses | Cons |
|---|---|---|---|
| Volume Booster | Increases volume to 200 percent of standard volume | Simple interface, works without root | Can distort the sound at maximum |
| Equalizer FX | 10-band equalizer + bass amplifier | Preset support, low battery consumption | Advertising in the free version |
| ViPER4Android | Advanced sound processing, compressor, limiter | Maximum customization, supports Bluetooth 5.0+ | Complex setup, requires Magisk for full functionality |
Try Volume Booster first:
- Install the application and open it.
- Move the slider 150-180% (donβt put 200% β there will be a strong distortion).
- Turn on the option of Apply to Bluetooth.
- Restart the music playback.
ViPER4Android is suitable for power users.
- π§ Activate Bluetooth Compatibility Mode in Settings.
- ποΈ Enable Master Limiter and install Max Gain on 3-5 dB.
- π In Convolver, select Preset Club or Live.
Install the latest version of Magisk (for root access)| Download ViPER4Android from the official website (not from Play Market)| Install drivers manually via Magisk Module | Disable other audio modifiers-->
π‘
ViPER4Android is the best, but it requires root rights to work properly, and without them, some of the features will be unavailable.
5. Update of the firmware of the headset and smartphone
Manufacturers regularly release updates to fix sound problems. For Xiaomi headsets, the firmware is updated through the Mi Home or Xiaomi Wear app (depending on the model).
Instructions for Xiaomi AirDots Pro 2:
- Connect the headset to your smartphone.
- Open Mi Home β Device profile β Settings (βοΈ) β Firmware update.
- If a new version is available, install it (make sure the headphone charge is >50%).
For a smartphone, check for updates along the way:
Settings β About the phone β System update
After updating, reset the headset settings to factory:
- π Put the headphones in the case.
- π Press the button on the case on 10-15 seconds (before the indicator flashes red/white).
- π Connect again via Bluetooth.
π‘
If the sound gets worse after the update, roll back the headset firmware through the Mi Home app (if the previous version is available).
6. Reset Bluetooth settings and re-pair
Sometimes the problem is that the devices are not paired properly.
- Open Settings β Connections β Bluetooth.
- Click on the icon. βοΈ near your headset.
- Select Forget the Device (or Disable + Delete).
- Turn off Bluetooth for 30 seconds, then turn it back on.
- Transfer the headset to pairing mode (usually pressing the button for 3-5 seconds before the indicator flashes).
- Reconnect it.
If the Xiaomi headset is not defined, try:
- π Charge the case to 100% (sometimes a low charge blocks pairing).
- π± Reboot your smartphone.
- π Reset network settings: Settings β Connections β Resetting Wi-Fi, Mobile Network and Bluetooth.
π‘
After resetting Bluetooth, all the stored devices will be deleted. MAC-addresses of important gadgets (such as smartwatches) if they are not automatically connected.
Hardware methods: cleaning and checking of speakers
If the software didn't work, the problem could be physical contamination of the speakers or wear on the membranes.
- π Light a flashlight into the sound holes β if dust or pile is visible, carefully remove them with a soft brush (do not use toothpicks!).
- π§ If your headphones get caught in rain or sweat, dry them in rice or silica gel for 24 hours (do not use a hair dryer!).
- π Check the sound balance: in some models (for example, Redmi Buds 3 Pro) you can separately adjust the volume of the left / right earphone in the Mi Home application.
β οΈ Warning: If the sound is still quieter or wheezing is seen, the speaker membrane is probably damaged, in which case repairs are only possible in the service center - disassembly by yourself will lead to loss of warranty.
To check for hardware health, connect the headset to another device (for example, a laptop or tablet). If the problem persists, a malfunction in the headphones. If the sound is normal, look for the reason in the settings of the smartphone.
