How to increase the volume of AirPods Pro on Xiaomi smartphone: from basic settings to hidden features

Why AirPods Pro is Quietly Playing on Xiaomi and What to Do About It

You bought an AirPods Pro, plugged it into a Xiaomi Redmi Note 12 or POCO X5 Pro, but the sound is barely audible even at maximum volume? The problem is familiar to many iPhone owners who use it with Android devices, because of the limitations of the Bluetooth A2DP protocol, the difference in audio processing between iOS and MIUI, and the factory volume limits set by Apple to protect hearing.

In this article, we’ll look at 7 proven ways to turn up the volume of the AirPods Pro (1st and 2nd generation) on any Xiaomi smartphone, from basic audio settings to hidden engineering menus and third-party apps. Importantly, some methods require developer rights or install additional software, so read the warnings carefully before you act.

If the problem occurred suddenly (the sound was normal before), check first:

• 🔋 Headphone Charge – at a level below 20%, the volume automatically decreases.
• 🧹 Clean speakers – A buildup of earwax or dust can drown out sound.
• 📱 Updates MIUI — Some firmware versions have bugs with Bluetooth audio (especially in the MIUI 13.0.4–13.0.6).

Method 1: Configure volume limit in MIUI

By default, Xiaomi limits maximum volume through security settings, and this limit applies to Bluetooth-connected devices, including the AirPods Pro.

1. Open the Settings. → Sound and vibration.
2. Switch to additional settings (or depending on the version of MIUI).
3. Choose Safe Volume or Volume Limitation.
4. Turn off the slider Limit volume or move it to maximum.

If there's no Safe Volume, your device is using a different limiting system.

Settings → Special features → Hearing → Turn off “Safe Sound”

💡

After disabling restrictions, check the volume in the YouTube or Spotify app – some apps have their own limits that are independent of system settings.

Method 2: Enabling Developer Mode and Changing Bluetooth Parameters

You can use the developer menu to increase the power of Bluetooth audio transmission, which sometimes solves the problem of quiet sound.

1. Activate Developer Mode: Go to Settings → About Phone. tap the MIUI version 7 times (you will receive a notification "You became a developer").
2. Return to the main settings menu and open Additional settings → Developer settings.
3. Find the Network section and turn on: Absolute Bluetooth volume (if any). Disable Bluetooth bitrate restriction (A2DP).

Reboot your smartphone and check the sound.

On some Xiaomi models (for example, Mi 11 Ultra or Redmi K50 Pro) in the developer settings, Bluetooth Audio Codec is available. Try changing the codec from SBC to AAC or aptX - this can improve the quality and volume of the sound.

Method 3: Use of uniform sound amplification (Equalizer)

System or third-party equalizer will help not only increase the volume, but also improve the sound of the AirPods Pro by adjusting the frequencies. MIUI there's a built-in tool:

1. Open Settings → Sound and vibration → Equalizer
2. Choose Basa or Rock presets – they usually raise the overall volume.
3. Manually lift the sliders 100 Hz and 1 kHz 3-5 dB.

If there is no built-in equalizer (for example, on the POCO M5), install one of the applications:

• 🎛️ Wavelet - Supports LDAC and aptX, has a built-in amplifier.
• 🔊 Poweramp Equalizer – Up to 150 percent of the original volume.
• 🎧 ViPER4Android — It requires root but gives you maximum control over sound.

Important: When using equalizers, watch for sound distortion. Excessive amplification of low frequencies can damage the AirPods Pro speakers due to overload.

Method 4: Reset Bluetooth settings and reconnect headphones

Sometimes the problem is that the devices are not paired properly.

Remove AirPods Pro from the list of associated devices |Reboot smartphone |Reset network settings (Settings → Data Transfer → Reset Wi-Fi, mobile network and Bluetooth) |Enable pairing mode on AirPods (press the button on the back of the case to flash white light) |Reconnect the headphones again

-->

If the sound doesn’t improve after the reset, try changing your Bluetooth profile:

1. Connect AirPods Pro to your smartphone.
2. Open the settings → Connected devices.
3. Slip the gear icon next to the AirPods Pro.
4. Choose Use for Media Audio (if available).

⚠️ Attention: On some firmware MIUI When you reset Bluetooth, you may lose the sound in your calls. → Annexes → Permit management → Phone and enable microphone access for AirPods Pro.

Method 5: Volume up through the Engineering Menu (MTK/Qualcomm)

On Xiaomi smartphones with Qualcomm Snapdragon processors (like Redmi Note 11 Pro+) or MediaTek (POCO M4 Pro), you can change the audio settings through the engineering menu. Careful: wrong actions can lead to crashes!

For Qualcomm:

1. Open the Phone app and enter the code: ##36446337##
2. Go to the Hardware Testing → Audio section.
3. Select Max Vol and set the value of 160 (by default 80-100).
4. Save the settings and restart the device.

For MediaTek:

1. Enter the code ##3646633##
2. Go to Hardware Testing → Audio → Normal Mode.
3. Find Max Vol options for Headset and Speaker, increase the values by 20-30%.

⚠️ Warning: Changes in the menu can cause sound distortion or damage to the speakers. Do not increase the values by more than 30% of the standard. If there is a wheezing or crackling after the changes, return the settings to the factory settings.

Method 6: Install custom firmware (for advanced users)

If none of the methods worked and the sound is still too quiet, the reason could be a limitation on the MIUI firmware level.Some custom firmware (like Pixel Experience or LineageOS) doesn't have such limits and works better with AirPods Pro.

Advantages of custom firmware for sound:

• 🔊 No artificial volume limits.
• 🎛️ Support for codecs LDAC aptX HD.
• 🔄 Ability to fine-tune Bluetooth stack.

However, there are risks:

• ⚠️ Loss of guarantee.
• ⚠️ Possible bugs with AirPods Pro connection (for example, no charge indicator).
• ⚠️ The need to unlock the bootloader (bootloader unlock).

If you decide to do this, follow the official instructions for your model on the XDA Developers forum or 4PDA. First, check the firmware compatibility with your device through the LineageOS Wiki site.

💡

Custom firmware can solve the volume problem, but it requires technical skills. Start with less radical methods, and only if they didn't help - consider firmware.

Method 7: Hardware inspections and alternative solutions

If the software methods did not give a result, the problem may be in the hardware:

If you are convinced that the problem is not headphones, try alternative solutions:

• 🎧 Use AirPods Pro with another device (like an iPad or MacBook) – if the sound is normal, the problem is with the smartphone.
• 🔄 Buy a Bluetooth transmitter (for example, Creative Transmitter) BT-W5), It connects to a smartphone over a wire and transmits sound to headphones without restrictions. MIUI.
• 📱 Set up the second. SIM-card with a tariff that includes unlimited traffic for music (for example, MegaFon "All for yours"), and listen through streaming services without compressing the sound.
