How to increase the volume on Xiaomi headphones: from standard settings to hidden features

You bought Xiaomi headphones, but the sound is too quiet even at maximum volume? The problem is familiar to many owners of Redmi AirDots, Mi True Wireless or wired models like Mi Basic. The reasons can lie in both the limitations of the MIUI firmware and the hardware features of the headphones themselves. In this article, we will discuss 7 working ways to increase the volume, from basic settings to hidden functions of the engineering menu.

It's important to understand that not all methods are equally safe. For example, changing the parameters in the engineer mode can lead to audio distortion or even damage to the speakers. We noted the risky steps with special warnings - read them carefully. At the end of the article, you will also find a table of methods for compatibility with popular Xiaomi headphones.

1. Check basic volume settings in MIUI

Before digging deeper, make sure the problem isn't with the banal settings. MIUI 12-14 has separate volume controls for media, calls and notifications, often confusing them or accidentally limiting the volume through the side buttons of the headphones.

How to check:

• 🔊 Open the Quick Settings Panel (swipe down from the top edge of the screen) and move the volume slider to the right to the stop. Make sure there is no "silent mode" icon next to the headphone icon".
• 🎧 Connect your headphones and play any audio (music, video, podcast). During playback, press the volume button on the smartphone body - sometimes MIUI Resets settings after connecting Bluetooth devices.
• ⚙️ Go to Settings. → Sound and vibration → Volume and check if the "Safe Volume" option is activated (it automatically lowers the sound level after prolonged use).

If you're still quiet after this manipulation, move on to the next section, and if you're using wired headphones, try connecting them to another device (like a laptop) to help rule out hardware malfunction.

2. Disable volume limit in developer settings

Android by default limits the maximum volume to protect hearing. In MIUI, this restriction can be removed through the developer menu. The method works on all Xiaomi smartphones, but requires the activation of hidden mode.

Instructions:

1. Activate the developer menu: go to Settings → About Phone and 7 times click on the MIUI version. the notification will appear "You became a developer".
2. Go back to the basic settings and open a new Developer section (usually at the end of the list).
3. Find the option to turn off absolute volume and activate it, which will allow you to adjust the volume separately on your smartphone and headphones.
4. Below, look for Bluetooth audio codec and select SBC or AAC codec – these usually give higher volume than aptX.

Activate the developer menu (7 taps according to MIUI)

Make a backup copy of the sound settings

Remember the current Bluetooth codec values

Reboot your phone after the changes-->

⚠️ Warning: When you turn off the restrictions, the sound may not only become louder, but it may also become more distorted at higher frequencies. If you notice wheezing or crackling, return the settings back.

3.Use of uniform equalizer (EQ) to amplify sound

If Xiaomi headphones quietly play only on certain frequencies (like weak basses), the problem can be solved with a built-in equalizer or third-party apps. MIUI has its own tool, but it is hidden in the audio settings.

How to set up built-in EQ:

• 🎛️ Go to Settings. → Sound and vibration → Equalizer (if no item, update) MIUI last-minute).
• 📊 Choose a preset called Bass or Rock, which amplifies the low and medium frequencies, which subjectively makes the sound louder.
• 🔧 Manually lift sliders at 60 Hz, 230 Hz and 910 Hz at 3-5 dB. Do not increase high frequencies (from 5 kHz) to avoid distortion.

For more flexible customization, install Wavelet (free on Google Play).It supports Xiaomi headphones and allows you to:

• 🔊 Apply automatic EQ headphone-based.
• 🎧 Use virtual surround to create a surround sound effect.
• 📱 Set up separate profiles for music, videos and calls.

💡

If after applying EQ sound became hoarse, reduce the amplification at frequencies above 3 kHz - this will reduce the load on the speakers.

Change of parameters in the engineering menu (for experienced users)

The Engineering Mode allows you to manually adjust the parameters of the sound card of the smartphone, which gives you the maximum volume increase, but if you set the wrong settings can damage the earphone speakers or the smartphone itself. Use it at your own risk!

Step-by-step:

1. Open the Phone app and enter the code ##36446337## (some Xiaomi models run code ##4636##, then select Hardware testing → Audio).
2. From the Hardware Testing menu, select Audio → Headset Mode (for wired headphones) or Headset Mode (Bluetooth).
3. Find options: - Max Vol (maximum volume) - increase the value from 80 to 100. - Type - select Media for multimedia. - Value - set 15 (usually 10 by default).
4. Press Set and restart your smartphone.

⚠️ Attention: If after changes in the headphone speakers there is background noise or the sound began to "break" at high volume, immediately return the values to standard. Prolonged use of inflated parameters can lead to burnout of the sound chip of the smartphone.

5. Verification of Bluetooth codec compatibility

Xiaomi’s wireless headphones (such as Redmi AirDots 3 or Mi True Wireless 2) support multiple audio codecs that affect volume and sound quality. By default, MIUI selects the codec automatically, but not always optimally.

How to change the codec:

• 🔗 Connect headphones to your smartphone via Bluetooth.
• 📱 Open the Settings. → Connected devices → Settings gear next to the name of the headphones → Codec.
• 🎵 Try the following codecs in decreasing order of volume: SBC — basic, loudest, but with mediocre quality. AAC — AptX is high quality, but quieter and doesn’t work on all Xiaomi smartphones.

If the sound is quieter after changing the codec, return the settings back. Also note that some codecs (for example, aptX Adaptive) can automatically turn down the volume when the Bluetooth signal is weak.

6. Resetting headphones and smartphone settings

Sometimes the problem is a software failure — for example, after updating MIUI or improper connection of the headphones, in which case the reset will help.

For wireless headphones:

• 🔄 Place both headphones in the case and press the button on the case for 10-15 seconds until the indicator flashes red and white.
• 📱 On your smartphone, remove the device from the Bluetooth list (Settings) → Bluetooth → Push the gear. → Delete).
• 🔗 Reconnect your headphones as a new device.

For the smartphone:

• 📲 Go to Settings. → The phone. → Resetting settings → Reset network settings. This will delete all stored Bluetooth devices and network settings.
• 🔧 If the problem persists, perform a soft reset (Settings). → Additionally. → Resetting settings → Reset all settings. Don't use a full reset, it will delete all data.

💡

Resetting the headphones to factory settings removes all user audio profiles, including the EQ settings in the Mi Earphones app, and you'll have to reset them once you reset them.

7. Third-party applications for sound amplification

If built-in methods didn't work, try specialized applications. They work in different ways: some amplify the signal at the OS level, others modify the audio stream in real time. We tested the 3 most effective options for Xiaomi.

Top.-3 applications:

1. Volume Booster GOODEV (Google Play) 🔊 Increases volume by 20-30% due to modification of the audio driver. 📱 It works without root, but requires permission to change system settings. ⚠️ It can cause distortion at maximum volume.
2. Equalizer FX (Xiaomi-enabled headphones) 🎛️ 10-band equalizer with presets for different genres. 🔧 Includes a bass amplifier and a virtual subwoofer. 📲 Compatible with MIUI 12-14, but may conflict with the built-in EQ.
