How to increase the volume of headphones Xiaomi Redmi AirDots 2

Many owners of the popular Xiaomi Redmi AirDots 2 wireless headphones face the unpleasant situation when the standard volume level is simply not enough, this is especially noticeable in noisy places such as the subway, city streets or the gym, where the background hum overlaps music. Low sound level can be caused by software limitations of the Android operating system, codec features or simply the wrong settings of the equalizer.

There are several proven ways to get around these limitations and make the most of your life. TWS-In this article, we will discuss both system settings and the use of third-party utilities that will help to significantly improve the sound picture. It is important to understand that excessive amplification can lead to distortions, so you need to act carefully.

Before we start taking any drastic measures, we should rule out the commonplace causes of quiet sound, such as contamination of the speaker grid or desynchronization of channels. Proper diagnosis of the problem is the first step to high-quality sound. Next, we will look at each method of increasing the volume in detail.

Basic inspection and physical cleaning of the device

Often the problem is not the software, but the simple physics, where the sulfur and dust that build up on the speaker grid create a dense plug that blocks the sound wave output, which makes even at maximum volume the sound seem deaf and quiet, and regular hygiene of the headphones is the key to clean and loud sound.

Use a soft dry toothbrush or cotton swab slightly soaked in alcohol to clean. Avoid sharp objects, as you can damage the speaker membrane inside the Redmi AirDots 2 body. Also check if the earbrush fits tightly to the ears, as poor insulation reduces the perceived volume of the basses.

Another important aspect is checking the channel balance: sometimes one earbud plays quieter than the other or both channels are not synchronized. Make sure that your smartphone's Bluetooth settings do not activate mono mode features or assistive settings that may limit audio flow.

• 🧹 Clean the speaker mesh with a soft brush of dust and sulfur.
• 🔌 Reconnect the headphones by removing them from the list of associated devices.
• 🔋 Check the charge level, as when the battery is discharged, the sound may become quieter.

⚠️ Warning: Never try to clean the speaker grid with sharp metal objects or needles - this is guaranteed to rupture the membrane and completely break the headphones.

Set up the system equalizer Android

Android provides built-in audio management tools that are often neglected. In the audio settings menu or in the About Phone section, you can find a basic equalizer. For Xiaomi owners, advanced functionality is often available through the MIUI Sound app or a standard music player.

In the equalizer, you have to lift all the sliders up, creating what's called a slide. Pay special attention to the average frequencies, because that's where most of the vocals and instruments are, but don't push them to the maximum to avoid clipping.

Also in the audio settings, there is often a feature called "Mi Sound Enhancer" or "Sound Improvement" activating this option allows you to select a headphone profile or customize the scene. Redmi AirDots 2 is best suited for the "In-ear" profile or manual mode with high-frequency amplification.

💡

Turn on the Dolby Atmos feature in the audio settings if it is available on your smartphone – this will add volume and increase the overall volume of the output signal.

Remember that some third-party players have their own amplification settings that override the system. Check the settings of your main music app, such as YouTube Music or Spotify, and make sure that there is no volume limit.

Use of volume-booster applications

If the system means are not enough, specialized booster applications come to the rescue. The most popular and effective solution is the Volume Booster GOODEV application. It allows you to programmatically amplify the signal output to a Bluetooth device, exceeding the standard 100% volume of Android.

When you first start such an application, you need to be extremely careful. It is recommended not to set the gain above 20-30%, as this can lead to overloading of Redmi AirDots 2 speakers and unpleasant wheezing. The algorithm is simple: the application receives an audio signal, amplifies it digitally and sends it to the output.

There are other analogues, like Super Volume Booster or Bass Booster, which work on a similar principle, but they can have different interfaces and additional noise reduction functions, and it's important to choose high-rated applications so that you don't harm the system.

⚠️ Attention: Prolonged use of boosters at maximum power can cause the headphone speakers to overheat and physically fail. Use moderate gain values.

Once you install the app, run the test sound and gradually increase the booster slider. Once you hear the distortion, turn it down a little bit, which will be your optimal volume limit for this model.

Activation of absolute volume mode

One of the most common causes of silent sound is the desynchronization of smartphone and headphone volume levels. Android and Bluetooth headsets can interpret the volume command differently. The solution is to include the "Absolute Volume" mode in the developer menu.

To access these settings, you need to activate the developer mode. Go to Settings → About the phone and seven times quickly click on the build number (MIUI Version! Then the "Advanced Settings" section will appear in the additional menu» → «For developers».

In the list of engineering options, find the item "Disable absolute volume." If it's turned off, turn it on, if it's on, try turning it off. You need to experimentally determine the state in which the volume slider of the phone will completely control the sound in the headphones.

Once you change this setting, be sure to reboot your smartphone completely and reconnect Redmi AirDots 2. This is a critical step to apply changes to the Bluetooth protocol.

Settings inside music apps

Remember that many streaming services and players have their own limitations and settings, such as Spotify and Yandex Music, which have their own equalizers and normalization features, and Normalization often levels the volume of tracks, making quiet songs louder, but can also understate the overall dynamics.

You can find the "Loudness" option in YouTube Music or YouTube settings that allows you to increase the sound level on top of the system. This works effectively for video content. Also check the stream quality: with low sound quality (96 kbps), the dynamic range is narrower and the sound seems quieter.

Set the maximum playback quality in the application settings. High bitrate (320 kbps) provides a denser and louder sound. For local files, use players like PowerAmp, which have powerful built-in amplifiers and equalizers.

Note the audio file format. Loss formats, such as low-bitrate MP3s, can sound quieter and flatter than modern AAC or FLAC codecs.

Resetting settings and reflashing headphones

If software methods didn't help, there may have been a failure in the headphones themselves.The Xiaomi Redmi AirDots 2 supports factory resets.This often solves problems with left and right channel desynchronization, which directly affects volume.

To reset, place the headphones in a case, press the touchpads on both headphones simultaneously and hold for about 20 seconds until the indicators flash red several times. After that, remove the device from Bluetooth on the phone and perform the pairing again.

It’s also worth checking for headphone updates through the Xiaomi Earbuds app (or Mi True Wireless Earbuds), which the company’s engineers periodically release updates to fix audio bugs and improve connection stability.

💡

A full reset of headphones often solves 90% of software problems with sound if the speakers are physically sound.

In rare cases, you may need to flash through special utilities on a PC, but for normal user operation, a standard reset is enough. If this does not help, the problem may lie in the hardware.
