Xiaomi Buds 4: How to increase volume and adjust the sound

When buying flagship wireless headphones like the Xiaomi Buds 4, users expect to have perfect sound quality and ample volume. However, in practice, many people face a situation where maximum sound level is not enough in noisy places, whether it is a crowded subway car or a busy street. This can be due to the software limitations of regional versions, Bluetooth settings or simply the features of the acoustic system of a particular model.

In this article, we'll look at all the ways you can improve your audio output. System constraints often hide the real potential of your device, and their smart workarounds allow you to get a richer, louder sound without losing quality. We'll look at both standard methods through the application and more advanced techniques.

It is important to understand that excessive volume can negatively affect hearing and shorten the life of speakers. Sound pressure above 85 dB with prolonged exposure is considered dangerous for the human hearing aid. So use the methods described below wisely, trying to find a balance between the desired volume and the safety of listening.

Basic setup through the Xiaomi Earbuds app

The first and most obvious step is to use official software: To manage the Xiaomi Buds 4 headphones, you need to install the Xiaomi Earbuds app (or Mi Buds M8 in some markets). This is where the main levers of managing the audio profile are located. Once you connect the headphones to your smartphone, the app will automatically prompt you to update the firmware, which often solves problems with quiet sound.

Inside the app, you should go to the audio settings section. Here you will find an equalizer that allows you to adjust frequency characteristics. Often a standard Balance or Bas profile may sound quieter due to software compression. Switching to a Bright profile or manually adjusting sliders can visually and acoustically add volumes to medium and high frequencies, which subjectively makes the sound louder.

Also worth paying attention to is the noise reduction function (ANC). In some scenarios, active noise cancellation can "crush" a useful signal along with external noise. Try switching mode to "Transparency" or completely disabling the ANC to check if the volume level changes. For some users, turning off this feature gives a 10-15% increase in volume.

• 🎧 Open the app and select Bright Sound Mode for maximum impact.
• 📱 Make sure that the option “Absolute Volume” is disabled in Bluetooth settings (if available).
• 🔄 Update the headphone firmware to the latest version through the device menu.
• 🎚️ Manually lift all the sliders of the equalizer on 2-3 dB above standard values.

Synchronizing Bluetooth Volume on Android and iOS

One of the most common causes of silent sound is the de-synchronization of volume levels between the smartphone and the headphones themselves. Bluetooth allows devices to independently control their volume, and sometimes the phone thinks it has turned the sound 100% and the headphones are left 50%.

On Android devices, you need to activate the developer menu. Go to Settings → About phone and quickly click on the build number seven times. Then a new option will appear in the settings menu, "Additional settings" or "Extended settings", where you need to find the "Developers" section. Here you need to find the option "Disable Absolute Volume". If it is turned off, if it is turned off, try to turn on and restart the device.

iPhone owners should also check the settings. While iOS tightly controls Bluetooth volume, sometimes resetting the network settings helps. → Mainstream → Removing or resetting iPhone → Reset → Reset network settings. This action will not delete your data, but will return all network connections, including Bluetooth protocols, to factory parameters, which often eliminates software volume bugs.

⚠️ Warning: After changing the absolute volume settings, be sure to turn off Bluetooth entirely on your smartphone, put your headphones in your case and close it for 10 seconds, then re-pair.Without this step, the changes may not take effect.

Use of third-party sound amplifiers

If system methods are not enough, third-party equalizers and amplifiers come to the rescue. There are many solutions for the Android platform, such as the Volume Booster GOODEV or Bass Booster. These programs create a software layer on top of the system sound, forcefully amplifying the signal before sending it to the Bluetooth module.

When using such utilities, it is important not to set the Boost gain value to the maximum.The optimal value is considered to be in the range of 20-40%. Exceeding this threshold leads to wheezing, especially at low frequencies, and can cause clipping (digital signal restriction), which sounds extremely unpleasant and can damage the membranes of the Xiaomi Buds 4 speakers.

For iOS users, the choice of third-party amplifiers is limited by Apple's security policies, but there are equalizer apps that work through a local player or system audio hacks (require jailbreaking, which is not recommended).The alternative is to use a built-in equalizer in music streaming services such as Spotify or Apple Music, where you can lift all frequencies manually.

• 🔊 Download the verified volume booster from the Google Play Store.
• ⚙️ Set the gain level not higher than 30% to maintain quality.
• 🎵 Activate the “Night Mode” function in player apps to level the volume.
• 🚫 Avoid using multiple amplifiers at the same time to avoid conflict.

Comparison of volume levels with competitors

To objectively gauge how quiet your Xiaomi Buds 4s are, it’s useful to compare them to other models on the market.Technical specs often indicate maximum sound pressure, but the real perception depends on the design of the case and the driver settings. The table below compares the subjective volume of different models. TWS-headphone.

As the data shows, Xiaomi Buds 4 is at the top of the rankings in potential volume.If your headphones sound quieter than mid-range competitors, the problem is almost certainly software or grid contamination, not hardware.

💡

Xiaomi Buds 4 is technically capable of delivering loud sound comparable to top-end models, so quiet sound is a fixable anomaly, not a design feature.

Physical cleaning and speaker maintenance

And don't ignore the physical condition of the device. Within a few months of use, earwax and dust can clog up the speaker's protective grids, and this creates a mechanical obstacle to the sound wave, jamming the high frequencies and the general volume. Visually, the pollution may not be noticeable, but the impact on the acoustics is huge.

To clean the Xiaomi Buds 4, use a soft toothbrush or a special sticky mass (cleaning gel). Carefully brush the grid to remove plaque. It is strictly forbidden to use sharp objects such as needles or pins, as they easily pierce the speaker membrane, which will lead to irreversible breakage.

Check the sound after cleaning. Users are often surprised at how louder and cleaner the headphones become after a simple hygienic procedure. Regular cleaning once a month will help maintain optimal volume and prolong the life of the device.

• 🧹 Use a dry soft brush to remove dust from the nets.
• 💨 Gently blow the speaker holes (not with your mouth, better with a pear).
• 🚫 Do not use alcohol or solvents to wipe the nets.
• 👂 Check your earbuds (ear linings) for contamination.

⚠️ Warning: If the sound starts to wheez or disappears in one of the channels after cleaning, stop using immediately and contact a service center.
