Youβve turned on your favorite track, but the sound in Xiaomi headphones is barely audible even at maximum? The problem of quiet sound is found in both wired and wireless models β from the budget Redmi Buds to the flagship Xiaomi FlipBuds Pro. The reasons lie in the limitations of MIUI firmware, Bluetooth codec settings or hardware features of the headphones themselves.
In this article, we'll look at 7 proven ways to turn up the volume, from basic smartphone settings to hidden engineering menus to modifications to system files. Importantly, some methods require root rights or cancel warranty, so we'll highlight the safe and risky options separately.
1. Check basic volume settings on Xiaomi
Before digging deeper, make sure the problem isn't with the trivial settings. Xiaomi has separate volume controls for media, calls and alarms - they're easy to confuse.
Open the Quick Settings Panel (swipe down from the top edge of the screen) and check:
- π Volume slider - it should be at maximum (the indicator lights up green) Sometimes it gets lost after connecting new headphones.
- π§ Headphone mode - in Settings β Select the Music or Game profile (they give you a Music or a Game profile). +10-15% volume compared to "conversation").
- π Do Not Disturb mode is turned off β it can automatically turn down the volume for all devices.
If the sound is still quiet after this manipulation, then move on to the next step. Note: on some models (for example, Xiaomi 13 Pro) in MIUI 14+ there is a separate volume control for Bluetooth devices, which can be found in the menu of the connected gadget.
2. Equalizer and sound effects setup
Xiaomi's built-in equalizer can both improve and degrade sound. By default, the "Normal" preset, which cuts the high and low frequencies, creates the illusion of quiet sound.
To optimize the sound:
- Go to Settings β Sound and vibration β Equator.
- Choose a preset called "Bas" or "Rock" - they amplify the low frequencies, which subjectively makes the sound louder.
- Activate the option βAdaptive soundβ (if any) β it automatically adjusts the volume to the surrounding noise.
For owners of Xiaomi Buds 4 Pro and others TWS-headphones LDAC or aptX Adaptive:
- ποΈ Enable high-quality codec in Bluetooth device settings (path: Settings) β Connected devices β Headphones β Sound settings).
- π Reconnect your headphones after changing the codec β sometimes a reset connection is required.

If your headphones have your own app (e.g., Xiaomi Earbuds for FlipBuds Pro), upgrade to the latest version β new releases often optimize sound profiles.
3. Reset Bluetooth settings and re-pair
Errors in the profile of a Bluetooth device are a common cause of quiet sound, for example, if the headphones previously connected to another phone with volume restrictions, these settings could stick to their profile.
Perform a full reset:
Forget the device in Settings β Bluetooth| Turn off the headphones for 30 seconds | Turn on pairing mode (usually hold the power button 5-10 seconds) | Connect again and check the volume-->
For models with MIUI 13+, there is a hidden option to reset all Bluetooth settings:
Settings β About the phone β MIUI version (shap 7 times)
β Additional settings β Network reset β Reset Bluetooth settingsβ οΈ Warning: After resetting, you'll have to reconnect all Bluetooth devices, including smartwatches and fitness bracelets. Don't use this method if you have a lot of conjugated gadgets.
4. Engineering menu and hidden sound settings
Xiaomi has a hidden engineering menu where you can manually increase volume limits, which works on most models, but requires caution β incorrect changes can lead to distortion of the sound.
Instructions for MIUI 12-14:
- Open the Phone app and enter the code: ##36446337## (or alternative ##4636## β select Phone Information).
- Go to Hardware Testing β Audio β Headset Mode.
- Check the current Max Vol values (usually 150-160). Try to increase by 10-20 units, but do not put above 180 - this is fraught with distortion.
- Save the settings and restart the phone.
For POCO or Redmi owners with custom firmware, the path may be different. If the menu doesn't open, try using the MTK Engineering Mode app (available on Google Play for MediaTek-based devices).

5 Modification of system files (for advanced)
If previous methods failed, you can change the volume limits at the system file level, which requires root rights or an unlocked bootloader, and also cancels the warranty.
Instructions for devices with Magisk:
- Install the ViPER4Android module via Magisk Manager.
- In the module settings, activate: π Master Limiter (set 0 dB) ποΈ Volume Boost (try it out) +5...+10 dB) ποΈ Dynamic System (disable if wheezing occurs)
Restart the device and check the sound.
For users without root, there is a workaround through ADB:
adb shell settings put global volume_music_speaker_scale 1.5
adb shell settings put global volume_alarm_speaker_scale 1.5
adb shell settings put global volume_notification_speaker_scale 1.5β οΈ Attention: Scaling up the volume above 1.5 can cause the sound to be distorted at high levels. On some models (e.g. Redmi Note 11), this also causes the processor to overheat during long-term playback.
6. Hardware causes of silent sound
If the software methods did not give a result, the problem may lie in the "iron":
| Reason. | Signs. | Decision |
|---|---|---|
| Contaminated connector 3.5 mm or Type-C | The sound disappears when the stacker moves, wheezing is heard | Clean the connector with alcohol and compressed air. For Type-C, check the integrity of the contacts. |
| Wear of the dynamics membrane | Silent sound + distortion at high frequencies | Replacement of the speaker in the service center (cost) ~1500-3000β½) |
| Problems with Bluetooth antenna | The sound is interrupted, quiet only in wireless headphones | Check the integrity of the antenna (often departs after falls). on Xiaomi 11T Pro it is a typical problem. |
| The weak sound amplifier in the phone | Silent sound in all headphones, but normal in speakers | Use an external DAC (e.g. Xiaomi USB-C Audio Adapter) |
To diagnose hardware problems, connect your headphones to another device. If the sound is quiet, the headphones are to blame; if it becomes normal, the smartphone is to blame.

Xiaomi models with Snapdragon 8 Gen 1/2 processor (e.g. Xiaomi 12 Pro, 13 Ultra) often have a chip defect in the sound amplifier. Symptoms: quiet sound in the headphones + normal in the speakers. The solution is to replace the motherboard.
7. Alternative solutions: applications and accessories
If nothing helps, consider these options:
- π§ Sound amplifiers: Volume Booster GOODEV β Increases volume to 200% (works without root, but can distort sound). FX β Advanced equalizer with preamplifiers.
- π External DAC/amplifiers: Xiaomi USB-C to 3.5mm Adapter (built-in amplifier, ~1000β½). FiiO BTR3K (Bluetooth headphone amplifier, ~5000β½).
- π Replacement of headphones: If your model is older 2-3 In years, speakers could have degraded. 4 Pro or SoundPEATS Air3 grant 30-40% louder sound with the same settings.
For owners of the POCO F3/F4 and other models with a 3.5 mm connector, there is an unexpected solution: use a Type-C β 3.5 mm adapter even if you already have a 3.5 mm connector.
