How to increase the volume of Xiaomi wireless headphones

Users often face a situation where new Xiaomi or Redmi wireless headphones don’t sound loud enough, especially in noisy places.This may be due not to a defect in the device, but to software limitations of the Android operating system or regional hearing safety regulations. Owners of Chinese brand gadgets MIUI and HyperOS have access to advanced settings that allow you to bypass standard limits.

Before resorting to radical methods, basic diagnostics must be performed to rule out physical damage or connection problems. Often, a quiet sound is the result of dissynchronizing the volume levels of the smartphone and headset. In this article, we will discuss proven ways that will help you to squeeze the most out of your TWS-Headphones without loss of audio quality.

⚠️ Warning: Excessive amplification of sound at high frequency can lead to irreversible damage to speakers or hearing.

Basic check and pairing of devices

The first step should always be to check the physical condition and correct connection. Make sure that the protective mesh of the speakers is not filled with earwax or dust, as this is a common cause of falling volume.

Then you have to check the volume level in the system. Sometimes after reconnecting the Bluetooth device, the smartphone resets the sound level to a minimum. Open the control panel and twist the slider to the maximum. Also, make sure that the Bluetooth settings include the option Absolute Volume Level, which synchronizes the volume of the phone and headphones.

Try turning off the headset in the Bluetooth menu, select Forget the Device, and do the pairing again. This action often eliminates software failures of the data protocol. If the problem persists with only one earphone, check the channel balance in special features.

Equalizer settings in MIUI and HyperOS

Xiaomi shells provide built-in tools for fine-tuning the sound that users often ignore. Go to Settings → Sound and Vibration → Sound Effects. Here is a built-in graphic equalizer to amplify certain frequencies. To increase the overall volume, it is recommended to choose a preset "Rock" or "Pop", as they have a steeper amplitude of lift.

Some firmware versions have Mi Sound Enhancer, which greatly improves detail and perceived loudness without distortion, and also pay attention to Dolby Atmos settings if your model supports them – Dynamic mode often makes the sound louder and more saturated.

Be sure to check the settings of a particular music app. Services like Spotify, Yandex Music or YouTube have their own equalizers that can override system settings. Make sure the app doesn't have Night Sound or volume limiting.

💡

For maximum effect, turn on Mi Sound Enhancer and select the Pilot or Rock profile in the sound settings.

Use of engineering menu and Android codes

Android has a hidden engineering menu that allows you to change the system settings of audio drivers. To get there, open the Phone app and dial the combination ##6484## or ##4636##. The menu may vary depending on the processor model and Android version.

You can find a section that is related to audio or sound settings in the menu that opens. You can find Volume or Audio Debug. You can force the values for Media, Ring and Alarm channels to increase. Be very careful: changing unknown parameters can lead to distortion of the sound or its complete disappearance.

⚠️ Attention: Entering the engineering menu is at your own risk. Do not change the values that are not sure, so as not to disrupt the audio track.

There is also a less risky method through the developer's settings. Go to Settings → The phone. → Press 7 times on "Version" MIUI» Then, in the "Developers" section, look for "Development Turn off the absolute volume level." Turning it on or off can solve the problem of quiet sound.

Third-party applications for sound amplification

If regular funds are not enough, specialized applications from Google Play come to the rescue. The leader in this category is Precise Volume, which allows you to create complex volume profiles with increments of 1% and use the built-in amplifier. The application can automatically raise the volume when you connect a Bluetooth headset.

Another powerful tool is the Volume Booster GOODEV. This app adds a software amplifier that can increase the output signal to 60% above the standard level. However, it is worth remembering that digital amplification always introduces distortions, so it is not recommended to twist the booster to the maximum.

For users who are ready for a deeper setup, Poweramp Equalizer can capture audio streams and allow complex filters, compression and limiting, which subjectively makes the sound louder and denser, and it is important to give the app the necessary permissions to access the system settings of the sound.

The problem of desynchronization of volume

A common problem for Xiaomi wireless headphones is to de-synchronize the volume levels between the left and right channels, or between the phone and the headset, which is that even at the maximum on the phone, the sound in the headphones remains quiet.

To perform the reset, remove the device from the paired list, turn off Bluetooth on the phone, then put the headphones in the case and press the buttons on both headphones (or the button on the case) for 10-15 seconds before the indicator flashes. After re-pairing, the system recalibrates the levels.

It’s also worth checking if Hearing Safety is activated in Android settings or in the headphone app itself (such as Xiaomi Earbuds), a feature that artificially limits the maximum volume for long-term listening, and turning off this limit will return full power.

💡

Complete soldering (resetting) of headphones through button retention often solves the problem of quiet sound more effectively than setting up the phone.

Audio codecs and transmission quality

The volume and sound quality are directly dependent on the Bluetooth codec used. The standard SBC codec provides the base quality, but the AAC, aptX or LDAC codecs can transmit a signal with a large dynamic range. Check in the Bluetooth settings (the "Bluetoothooth Codec" section in the developer menu) which codec is active.

Sometimes the automatic selection of the codec by the system is incorrect, resulting in a quiet or deaf sound. Forced switching to another codec (for example, from AAC to SBC or vice versa) can change the nature of the sound and make it louder.

Note that some cheap headphones may have a physical power limit that is very difficult to get around software, and in such cases, using external amplifiers or DAC adapters can give you a small boost, but miracles are not to be expected.
