How to Make Louder Sound in Xiaomi Headphones: From Standard Settings to Hidden Features

Quiet sound in headphones on Xiaomi, Redmi or POCO smartphones is a common problem that users face after updating MIUI, connecting new headsets or even for no apparent reason. The manufacturer limits the maximum volume by default to protect hearing, but sometimes these restrictions seem excessive. In this article, we will analyze all the working ways to increase volume, from basic settings to hidden functions of the engineering menu and third-party utilities.

It's important to understand that not all methods are equally safe. Some can cause sound distortion, overheating of the headphone speakers, or even damage to the audio chip of the smartphone. We will note the risky options and give recommendations on how to use them without harming technology. If you use wireless headphones (for example, Xiaomi AirDots or Redmi Buds), some of the ways will be different — this will also be discussed separately.

1. Check basic sound settings in MIUI

Before digging into the engineering menu or installing third-party apps, make sure the problem isn't in standard settings. Xiaomi often hides useful options in non-obvious sections.

Open Settings → Sound and vibration. Here, pay attention to:

• 🔊 Media volume - the slider should be at its maximum, sometimes it is reset after connecting new headphones.
• 🎧 Type of connected devices — MIUI It can misidentify headphones as "headset" (with a microphone), which reduces volume.
• 🔄 Adaptive sound – the function automatically adjusts the volume to the ambient noise.

If you're in your version MIUI There is a section called Sound Settings. → Sound effects, check if the bass amplifier or equalizer is on, and these options can artificially lower the overall volume in an attempt to "align" the sound. → Special facilities → Hearing – this is sometimes where volume restriction is activated for people with hearing problems.

2.Use of the engineering menu (#3646633##)

The engineering menu is a hidden settings section where you can manually adjust the settings of the audio chip, and caution: the wrong changes can cause the sound to crash or even "brick" the smartphone, and we recommend this method only to advanced users.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##3646633## (some models may require ##4636###).
3. Go to the Hardware Testing → Audio section.

In this menu you are interested in the following parameters:

• 🔊 Headset Volume is the maximum volume for wired headphones. The default value is usually 160, you can increase to 180-200 (but not higher than that!).
• 🎧 Speaker Volume – loudness speaker (not to be confused with headphones!).
• 🔄 Normal Mode: The audio chip is in mode. If the sound gets distorted, try changing it to High Performance.

Remember the initial settings |Do not turn up the volume above 200|Reboot the phone after the changes |Check the sound for distortion

-->

⚠️ Note: On Qualcomm Snapdragon models (e.g, POCO F3, Redmi Note 10 Pro: The Menu of Engineering MTK Engineering mode, even if it's from another manufacturer. Don't worry, that's okay. But on smartphones with MediaTek Helio, like Redmi. 9A) It is better not to touch the Mic Volume settings - it can break the microphone.

3. Sound amplification applications: Viper4Android and others

If standard methods don't work, third-party utilities will come to the rescue, the most popular being Viper4Android, but it requires root rights on most modern Xiaomi smartphones.

• 🎛️ Equalizer FX — A simple equalizer with presets for different genres of music, can increase the volume by 10-15%.
• 🔊 Volume Booster — an app that artificially amplifies the sound, but can cause distortions.
• 🎧 Wavelet – advanced audio processor with support LDAC And aptX. It's good for wireless headphones.

To install Viper4Android on Xiaomi without root:

1. Download APK from the official website (not from Google Play!).
2. Install Magisk and the Viper4Android FX module.
3. In the application settings, select the Headphone profile and activate Master Limiter (increases volume without distortion).

On models with MIUI 13/14 (Xiaomi 12, Redmi Note 11), the Viper4Android may not work due to manufacturer restrictions. In this case, try JamesDSP, an analogue with support for Android 12+.

💡

Before installing audio mods, back up your audio settings in MIUI: go to Settings → About Phone → Backup and save the Sound profile.

4. Bluetooth headphones setup: codec and bitrate

If you use wireless headphones (Xiaomi Air 2 SE, Redmi Buds 4, etc.), the problem may lie in the settings of the Bluetooth codec. By default, MIUI chooses SBC - the most versatile, but not the highest quality codec.

To change it:

1. Put the headphones on the phone.
2. Open Settings → Connected devices → Settings gear next to the headphones → Audio codec.
3. Choose AAC (best quality for Apple Music) or aptX (if the headphones support).

Also check the bitrate (data rate). In the same menu, you can have the option Audio Quality - set the maximum. On some models (POCO X3 Pro, Redmi K40), this option is hidden - then the Developer Options app will help (you need to turn on Developer Mode through Settings → About Phone → MIUI version by pressing 7 times).

⚠️ Note: Xiaomi with MediaTek chip (e.g. Redmi 10, POCO M4 Pro) codec LDAC It can be unstable, the sound will be interrupted, in which case you should choose aptX Adaptive or AAC.

5. Hardware problems: dirt, oxidation, malfunctions

If the software methods didn’t help, the problem could be in the hardware:

• 🔌 Oxidation of contacts in the connector 3.5 mm (relevant for Redmi 9, POCO M2 Check the connector for green plaque.
• 🧹 Contamination of the earphone speakers -- dust and pile turn down the volume. Clean them with a soft brush.
• 🔋 Weak battery in wireless headphones – at a discharge below 20%, the sound automatically mutes.

To check the 3.5mm connector:

1. Put your headphones on and move the plug a little bit, and if you hear a sound, it goes away, and it's a problem with the contacts.
2. Try other headphones. If they sound louder, your headset malfunctions.
3. Use a Type-C adapter (if you have a 3.5mm smartphone like the Xiaomi 11T).

On dual speaker models (POCO X3, Redmi Note 10S) check if one of them is disabled.

1. Open Settings → Sound and vibration → Sound quality.
2. Make sure that Stereodynamics mode is on.

6. Update MIUI and reset sound settings

Sometimes a quiet sound is a firmware bug. Xiaomi regularly releases updates to fix audio problems.

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, install it.

If the update didn’t help, try resetting the sound settings:

1. Open Settings → Applications → Application Management.
2. Find the Audio Settings (or Audio Settings) and select Storage → Clear Data.
3. Reboot the phone.

On models with MIUI 14 (Xiaomi 13, Redmi Note 12) can help reset Bluetooth settings:

1. Go to Settings → Connected Devices → Bluetooth Settings.
2. Select Reset (or Forget all devices).
3. Reconnect the headphones.

💡

After the update MIUI So the sound is quieter, try to revert to the previous version via Fastboot. 4PDA model-themed.

7.Alternative methods: from the tape recorder to USB-C

If nothing helps, consider the following non-standard solutions:

• 🎵 External DAC - a device connected through USB-C, It's good for audiophiles, like iBasso. DC05).
• 🔊 Bluetooth transmitter – if your smartphone has a 3.5mm problem, connect the headphones via an external adapter (e.g. Creative). BT-W5).
• 📻 FM-transmitter is an old but working way: transmit the sound to a car radio or radio.

For models without a 3.5 mm connector (Xiaomi 12 Pro, POCO F4), the only way out is a USB-C adapter or wireless headphones.

• Not all adapters are equally good. Cheap Chinese models can produce background noise.
• Nana MIUI Sometimes there's not enough power to power the adapter. OTG-feed-in.

On Xiaomi smartphones with Snapdragon 8 Gen 1/2 chip (e.g. Xiaomi 12S Ultra, Redmi K50 Gaming), USB-C → 3.5 mm adapters may not work properly due to driver conflict. The solution is to disable MIUI optimization for audio devices in the Developer Settings (option Disable USB audio effects).
