How to increase the volume on headphones Xiaomi AirDots: step-by-step instructions

Xiaomi AirDots headphones (including Redmi AirDots, AirDots Pro, Air 2/3) are popular for their combination of price and quality, but many users face the problem of insufficient volume. Even at maximum levels, the sound can seem quiet, especially in noisy environments or when listening to low-frequency music, the reasons for this lie in both hardware constraints (small speakers, weak amplifier) and software settings - the manufacturer often lowers the volume to protect the hearing.

In this article, we’ll look at 7 proven ways to turn up volume on Xiaomi AirDots, from basic smartphone settings to advanced methods using third-party apps and firmware modifications. It’s important to understand that some methods can affect sound quality or headphone life — so we’ll point out the risks and alternatives. If you’re willing to experiment, start with the safest options and move on to radical ones only when needed.

1. Checking basic volume settings

Before you resort to complex manipulations, make sure that the problem is not in the obvious settings. Often users overlook simple settings that limit volume.

On Android (including Xiaomi/Redmi/POCO smartphones):

• 📱 Open the Settings. → Sound and vibration.
• 🔊 Check the slider Media Volume – it should be at maximum.
• 🎧 Make sure your AirDots are selected in the Bluetooth section of the device (sometimes the smartphone automatically switches to the speaker).

On the iPhone:

• 🍎 Go to Settings. → Bluetooth and make sure AirDots are connected.
• 🔊 At Control Point (swipe down) check the volume level for media.
• 🔄 Turn off and reconnect your headphones via Bluetooth.

If the volume is still low, move to the next step, and note that some MIUI firmware (e.g., the global version) may have Safe Volume activated, which you need to turn off in the audio settings.

2.Use of equalizer to amplify sound

Built-in or third-party equalizers allow volume to be increased by adjusting frequencies, a technique that does not increase the physical power of the speakers, but makes the sound subjectively louder by amplifying certain ranges (such as low or high frequencies).

On Xiaomi smartphones:

1. Open the Music (or Mi Music) app.
2. Put it on the icon. ⚙️ Settings → equalizer.
3. Choose the preset Bass or Rock – they usually amplify the low frequencies, which makes the sound richer.
4. Manually lift sliders to 60 Hz, 230 Hz and 1 kHz at +3–+5 dB.

For other Android devices:

• 🎛️ Install the Equalizer app FX Wavelet (on Google Play).
• 🔧 Turn on the equalizer and select the Loudness preset or create your profile with 100-500 Hz gain.
• 🔊 Activate the option "Basampler" (if any).

On the iPhone, the equalizer is built into the settings:

1. Settings → Music → Equalizer.
2. Choose "Late Night" (enhances quiet sounds) or "R&B" (increases bass).

⚠️ Attention: Excessively amplifying low frequencies can cause the sound to be distorted ("wheezing") at maximum volume.

Install preset "Bas" or "Rock" | Increase sliders by 60-230 Hz | Reduce high frequencies (10-16 kHz) for balance | Check the sound for distortions-->

3. Turning off volume restrictions in MIUI

MIUI firmware (especially global and European versions) often contains hidden volume limits for Bluetooth devices, which can be removed through developer mode or special commands.

Method 1: Through the Developer's Settings

1. Activate Developer Mode: Settings → About Phone → MIUI version (shap 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the option “Disable Bluetooth Absolute Volume” and activate it.
4. Restart your smartphone and check the volume.

Method 2: Engineering menu (for advanced)

This method requires caution – wrong actions can disrupt Bluetooth.

1. Open the Phone app and type ##4636##.
2. Select Phone Information → Bluetooth.
3. Find the "ABS Volume" option and turn it off (if any).
4. Put the headphones back together.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) POCO X3) The engineering menu may be missing or blocked. Do not use third-party apps to activate it, it is dangerous for the system.

4. Volume-boosting applications

If the built-in methods didn't work, you can use third-party utilities, and they work in different ways: some modify the system settings, others amplify the sound programmatically.

Top.-3 Android:

• 🔊 Volume Booster – a simple booster with presets for Bluetooth devices.
• 🎧 Precision Equalizer – Advanced equalizer with volume gain up to 200%.
• 📱 ViPER4Android — Professional audio processor (requires root rights for full functionality).

Instructions for ViPER4Android (the most powerful option):

1. Download ViPER4Android (requires a version for your Android).
2. Install the ViPER4Android Driver (available in the same archive).
3. Open the app, go to Master Limiter and increase Max Amplification to 5-7 dB.
4. Turn on "Convolver" and select the preset Super Bass.
5. Save the settings and restart the smartphone.

There are fewer options for iPhones due to iOS limitations, but you can try:

• 🎵 Boom 3D — Enhances sound through frequency processing (works with Bluetooth).
• 🔊 Equalizer+ — Simple equalizer with presets.

💡

If after installing the booster, the sound began to distort, reduce the gain level in the application settings or turn it off for calls (so as not to damage the speakers).

5. Modification of the headphone firmware (advanced method)

This is only suitable for advanced users, because it requires reflashing headphones, it allows you to remove hardware volume restrictions, but fraught with loss of warranty and the risk of disabling the device.

What you need:

• 💻 Computer with Windows or Linux.
• 🔌 USB-Type-C Cable (to connect the case).
• 📦 Firmware for your AirDots model (see forums) XDA Developers or 4PDA).
• 🛠️ Flippy or nRF Connect for firmware.

Step-by-step:

1. Download nRF Connect and install it.
2. Connect the case with headphones to the PC via USB (earphones must be inside the case).
3. Start nRF Connect, select DFU (Device Firmware Update).
4. Download the firmware file (usually with the.zip or.hex extension).
5. Start the firmware process and wait until it is completed (don’t turn off the case!).

Models that support reflashing:

• ✅ Redmi AirDots (1st generation) – the most popular for modifications.
• ✅ AirDots Pro – requires special versions of the firmware.
• ❌ Air 2/3 — Protected from flashing (risk of "bricking").

⚠️ Warning: After flashing the headphones may lose compatibility with the original Mi Home app, and there will be problems with updates. On newer than AirDots Pro 2 (2021), firmware modification is almost impossible due to secure boot.

6 Hardware methods of increasing volume

If the software fails, you can try to improve the sound on the physical level, and these methods don't require any firmware intervention, but some of them can void the warranty.

Methods without indiscriminate headphones:

• 🧲 Magnetic cleaning - sometimes dust or oxidation of contacts in the case worsens the sound.
• 🔋 Battery replacement – if the headphones discharge too quickly, a weak battery may limit the power of the amplifier.
• 🎧 Using ear liners of a different size – a tight fit improves sound insulation, and the volume subjectively increases.

The following are the methods (for experienced ones only!):

• 🔧 Replacement of speakers – AliExpress sells more powerful speakers for AirDots (for example, with a resistance of 16 Ohms instead of 32 Ohms).
• 🔊 Installation of an additional resistor - allows you to increase the current on the speaker (requires a soldering iron and knowledge of electronics).

⚠️ Note: When you're decomposing Xiaomi AirDots, it's easy to damage plumes or microphones. If you're not sure about your skills, contact the service center. The cost of repairing after a failed modification may exceed the price of new headphones.

💡

Hardware methods give the most noticeable volume boost, but require skill and often lack warranty. Start with the safest options (cleaning, liners), and only if they don't help - consider disassembly.

Alternative solutions

If none of these methods worked, maybe the problem isn't with the headphones, but with the source of the sound or the processing of the sound.

Smartphone problems:

• 📱 Resetting sound settings – sometimes helps to return factory settings: → System system → Resetting settings → Reset network settings/sound.
• 🔄 Software Update – Check for smartphone and headphone updates (via Mi Home).
• 🎵 Use of external amplifiers – Bluetooth amplifiers (e.g. FiiO) BTR3) They can increase the signal strength.

Content issues:

• 🎧 Low recording quality – some tracks are initially recorded quietly. Try to normalize the volume in the player (ReplayGain option in Poweramp).
• 📺 Streaming Services – In Spotify or YouTube Music, check your sound quality settings (should be High or Very High).

Extreme measures:

• 🆕 Buying new headphones - if AirDots are old, maybe the speakers are worn out.Consider models that support aptX or LDAC (For example, Xiaomi Air 3 Pro).
• 🔧 Contact the service – if the headphones are warranty, describe the problem as “low sound quality” (don’t mention trying to turn up the volume).

💡

Before buying new headphones, check them at a show or with friends — sometimes the problem is individual hearing sensitivity. For example, people with hearing loss at high frequencies will subjectively hear a sound that is quieter.
