How to increase the volume of wireless headphones on Xiaomi: the complete guide

Weak audio in wireless headphones on Xiaomi smartphones is a common problem that spoils the experience of listening to music or watching videos. Even at maximum volume in MIUI, sound can remain quiet due to manufacturer limitations, Bluetooth codecs or audio profile settings. In this article, we will discuss all working ways to increase volume without loss of quality, from standard system functions to hidden features of the engineering menu.

Many users mistakenly believe that the problem lies in the headphones themselves, but 80% of the time to blame software limitations Android or MIUI. For example, Xiaomi default activated safe volume mode, which automatically reduces the sound level after exceeding the threshold of 85 dB. In addition, wireless headphones (especially budget models Redmi Buds or Haylou) often use compressed codecs like SBC, which limit dynamic range. But the good news is that almost all of these restrictions can be circumvented.

Before you go to radical methods, check the obvious points: headphone charge (below 20% the volume can automatically decrease), the cleanliness of the speakers (clogged grid extinguishes high frequencies) and the distance to the smartphone (at the border of the Bluetooth coverage area, the sound becomes quieter due to packet losses).

1. disable the limit of safe volume in MIUI

Xiaomi smartphones based on MIUI 12/13/14 have a built-in volume limit that works when you exceed 85 dB. This is done to protect your hearing, but often interferes with listening to music in noisy places.

Open Settings → Sound and vibration → Safe Volume. Here you will see a slider with a warning of the risk to hearing, move it to the right and confirm the action, then the maximum volume in the player or video will increase by 15-20%.

⚠️ Warning: Long-term listening to sound above 90 dB can lead to irreversible hearing loss. Use this feature only when necessary (for example, in transport) and remember to return the slider to its original position.

If you don't have Safe Volume on the menu, your MIUI version doesn't support this feature (relevant to older models like the Redmi Note 8), then move on to the next way.

2.Tune Bluetooth codecs for maximum sound

Xiaomi’s wireless headphones (such as the Xiaomi Buds 4 Pro or Redmi Buds 5) support several audio codecs: SBC, AAC, aptX and LDAC. By default, the system chooses SBC, the most versatile but also the most “compressed” codec that limits volume, to change it:

1. Connect the headphones to your smartphone.
2. Open Settings → Connected devices → Settings gear next to the headphones.
3. Choose Sound Quality or Audio Codec (name depends on MIUI version).
4. Try alternately AAC (better for Apple Music) and aptX (better for Spotify and local files).

🔹 Which codec to choose? LDAC It offers the best quality, but does not work with all headphones and can cause stuttering. aptX Adaptive is the gold standard for Xiaomi: it dynamically adjusts bitrate, keeping volume even with a weak Bluetooth signal.

If you don't have a codec in your settings, your smartphone or headphone model doesn't support your choice, and then a third-party app will help, as discussed in the next section.

3.Apps for amplification of sound: Equalizer and Volume Booster

If standard MIUI settings don't work, install one of the specialized applications, which work at the level of the system sound driver and can increase volume by 30-50% due to software signal processing.

📌 Top.-3 apps:

• 🎛️ Poweramp Equalizer is a plugin for the Poweramp player, but it works with other applications. It has pre-installed profiles for Xiaomi Buds.

⚠️ Note: Volume Booster applications can cause high volume audio distortions (wheezing, crackling). If you hear artifacts, reduce the amplification level in the application settings.

💡

💡

Before you install the equalizer, turn off the built-in equalizer in MIUI (Settings → Sound → Equalizer) to avoid a conflict of settings.

4. Engineering menu: hidden sound settings

Xiaomi smartphones have a hidden engineering menu where you can manually change the settings of the sound chip. This is the most effective way, but requires caution - incorrect settings can lead to failures.

🔧 How to Open an Engineering Menu:

1. Open the Phone app.
2. Enter the code ##36446337## (for MediaTek) or #4636## (for Qualcomm).
3. Go to the Hardware Testing → Audio section.

In the Audio menu, find the parameters:

• Headset Mode – Select High Performance.
• Max Volume – Increase the value from 80 to 100 (or as high as possible).
• Bluetooth Sco – Activate Enhanced Mode (if you have one).

⚠️ Note: Changes to the engineering menu are not saved after restarting. Use the app to fix the settings. MTK Engineering Mode (for MediaTek) or Qualcomm Engineer Mode (for Snapdragon).

5. Equalizer adjustment to enhance low and high frequencies

Sometimes the problem is not the overall volume, but the wrong frequency balance, for example, if the headphones are weak in bass or high frequencies, the sound seems quieter, and you can fix this through the built-in or third-party equalizer.

🔹 How to apply the settings:

💡

The equalizer doesn't increase the overall volume, but it makes the sound subjectively louder by amplifying key frequencies, which is safe for headphones and hearing.

6. Update of the firmware of headphones and smartphone

Manufacturers regularly release updates for wireless headphones that fix audio problems. for example, in Xiaomi Buds. 4 Pro after updating to version 4.7.15 The maximum volume level has increased 10%. You can check the relevance of the firmware through the Mi Earphones app (for the purpose of the application). Xiaomi/Redmi Buds or Haylou Fun (for Haylou).

🔄 How to update your headphones:

• 📱 Install an official app for your model (e.g. Xiaomi Earphones for Buds 3 Pro).
• 🔗 Connect the headphones to the smartphone.
• 🔍 In the app, find the Firmware Update or Firmware Update section.
• 📥 If a new version is available, download and install it.

⚠️ Warning: Don't interrupt the process of updating your headphones! If the battery runs out during firmware, the device may fail. Charge the headphones up to 50% before starting.

📲 Update MIUI:

Sometimes the quiet sound problem is solved by updating the system. MIUI:

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

7. Hardware causes of silent sound and their elimination

If the software methods didn't work, the problem could be in the hardware, and here are the most common reasons and ways to fix them:

🔧 Checking the headphone speakers:

• 🧹 Grid pollution: Use a soft brush or compressed air to clean. don't puncture holes with a needle!
• 🔋 Low charge: Xiaomi headphones at a charge below 15% automatically turn the volume down. Charge them to 100%.
• 🎛️ Driver malfunction: If the sound wheezes or disappears, contact the service center.

📱 Smartphone check:

• 🔌 Charging port/3.5 mm: If you use a wired headphone adapter, clean the port of dust (use a wooden toothpick).
• 📶 Bluetooth module: Reboot your smartphone and reset your network settings (Settings) → Connection → Reset Wi-Fi, mobile network and Bluetooth).
• 🔊 Smartphone speaker: Run a sound test through the engineering menu (#36446337## → Audio → Speaker Test).

Headphones Xiaomi Buds 3T Pro and Redmi Buds 4 Active have a hardware volume limit at the level of 92 dB. It is impossible to exceed it software - it is laid in the firmware of the controller.
