How to increase the volume in wireless headphones Xiaomi Redmi AirDots: all working ways

Xiaomi Redmi AirDots wireless headphones (including AirDots 2/3/Pro models) are often criticized for quiet sound — especially when listening to music in noisy places or while making calls. The problem is not always hardware constraints: in 80% of cases, the volume can be increased programmatically without having to replace speakers. In this article, we will analyze 5 proven methods, including hidden Android/iOS settings, equalizer customization and even headphone firmware — with detailed instructions for each model.

It is important to understand that the volume limit in Redmi AirDots is set by the manufacturer to protect the hearing (EU Volume Limit is not higher than 85 dB), but this limit can be circumvented legally without the risk of damaging the device, we will also tell you how to distinguish hardware problems (wear of speakers) from software, and what to do if the sound is completely lost.

1. Checking basic settings: what to do before changes

Before you go into deep settings, make sure that the problem is not trivial things.

• 🔊 Volume on phone: Press physical volume buttons on your smartphone while playing – sometimes system sound and media volume are separated.
• 🎧 Headphone volume: Twice tap the touchpad on any AirDots (except the first model) – this switches volume modes.
• 📱 Bluetooth codecs: In Bluetooth settings, select Redmi AirDots codec AAC or SBC (instead LDAC, slice-cutting).
• 🔄 Headphone reset: Press the button on the case of the charging case for 15 seconds - this will reset the settings to the factory.

If the sound is still quiet after this manipulation, then you can go to the following methods. Note: on the iPhone, some of the features (such as choosing a codec) may not be available - this is an iOS limitation.

2. Increase volume through phone settings (Android/iOS)

Smartphones artificially limit the volume for Bluetooth devices.

For Android:

1. Open the settings → Sound → additionally.
2. Find the option “Limit Bluetooth Volume” or “Safe Volume” and turn it off.
3. In some firmware (e.g. MIUI), you need to go to Settings → Special Options → Improve Sound and activate “Maximum Volume”.

For the iPhone:

iOS is stricter on security, but there is a workaround:

1. Go to Settings → Music → Equalizer.
2. Select the preset "Late Night" (increases low frequencies, which subjectively makes the sound louder).
3. Turn on Settings → Universal Access → Audiovisual → Monoaudio – this sometimes raises the volume by 10-15%.

Warning: Some smartphones (Samsung, OnePlus) may display a hearing risk warning after the restrictions are turned off.

3.Using an equalizer: how to "squeeze" the maximum out of sound

The correct equalizer settings can increase the volume by 20-30% without distortion.

• 🎛️ Wavelet (Android) – supports Redmi AirDots and has a built-in limiter (volume amplifier).
• 🎵 Equalizer FX — simple equalizer with presets for different genres.
• 🍎 Boom 3D (iOS) – paid, but gives a noticeable increase in volume due to 3D-effects.

The best settings for Redmi AirDots are:

⚠️ Warning: Do not lift the sliders higher +6 dB is going to cause distortion. If the sound starts to wheez after the equalizer settings, reduce the gain at high frequencies (3-6 kHz).

4. Headphone firmware: a risky but effective method

If nothing works, you can upgrade Redmi AirDots to a modified version with increased volume, which is only suitable for AirDots 2/3/Pro models and requires a computer.

Step-by-step:

1. Download the firmware from GitHub (choose the version for your model!).
2. Install the nRF Connect (Android/iOS) or QFlash Tool (Windows) program.
3. Connect the headphones to the PC in DFU mode: 1. Put the headphones in the case. 2. Press the button on the case for 10 seconds (the red indicator will light up). 3. Connect the case to the PC via USB.
4. Download the firmware via QFlash Tool by selecting the.hex or.bin file.

⚠️ Warning: The wrong firmware can permanently disable your headphones. If the sound is lost or distortions appear after the update, go back to the factory firmware (download it at Xiaomifirmware.com).

💡

Before you run the firmware, check the current version of the software: open the Mi Home app, find Redmi AirDots in the list of devices and see the About Device section.

5. Hardware causes of silent sound: when nothing helps

If the software methods have failed, the problem may be:

• 🔋 Battery discharge: At a charge level below 20%, the headphones automatically turn the volume down.
• 🔊 Contaminated speakers: Dust and earwax block the sound channels. Clean the speaker grid with a soft brush (do not use alcohol-containing liquids!).
• 🎛️ Damaged driver: If the sound is distorted or interrupted, the contact inside the headphone may have broken (requires repair).
• 📡 Bluetooth interference: Other 2.4GHz devices (Wi-Fi routers, microwaves) can "jam" the signal.

How to check the speakers:

1. Connect the headphones to another phone/PC.
2. Replay the test signal (e.g., here).
3. If the sound is quiet on all devices, the problem is with the headphones, if only on one, it's the smartphone.

💡

If the sound didn't recover after cleaning the speakers and the firmware didn't help, the membranes were probably worn out, in which case it's cheaper to buy new headphones than to repair old ones.

6. Alternative solutions: if nothing works

When all methods are exhausted, radical options remain:

• 🔧 Replacement of speakers: Xiaomi service centers change membranes for 800-1500 ₽ (model-wise).
• 🎧 Buying an amplifier: Bluetooth amplifiers (e.g. FiiO) BTR3K) add 10-15 dB of volume, but cost from 5000 ₽.
• 📱 Change of phone: Some smartphones (ASUS ROG Phone, Black Shark have a reinforced Bluetooth transmitter.

If you decide to buy new headphones, pay attention to models with support for the codec aptX Adaptive or LDAC – they provide a higher volume level without distortion. Among the budget options from Xiaomi, we recommend Redmi Buds 4 Pro or Xiaomi FlipBuds Pro.
