How to increase volume in Xiaomi Buds 3: all the ways from adjusting the software to hardware tricks

Why Xiaomi Buds 3 is playing too quietly and what to do about it

Owners of wireless headphones Xiaomi Buds 3 often face the problem of insufficient volume — even at maximum settings, the sound seems muffled compared to competitors. EU-versions of firmware or tuning of bluetooth codecs), and in hardware features - from clogged speaker grids to malfunctioning membranes.

In this article, we’ll look at all the working methods for increasing volume, from basic smartphone settings to firmware modifications to physical earbud cleaning. It’s important to understand that some of the ways can affect sound quality or device life — so we’ll highlight the safe and risky options separately.

If you just bought a Buds 3 and are disappointed with the quiet sound, start with the first three sections — they cover 90% of the time. For advanced users, at the end of this article, there are instructions on how to change system files and hardware improvements.

Method 1: Volume settings on your smartphone and in the Mi Earphones app

The first thing to check is the software restrictions on the smartphone side, and often the problem isn't with the headphones themselves, but with Android or iOS settings that artificially turn the volume down to protect your hearing.

On Android (especially on Xiaomi/Redmi/POCO):

• 📱 Open the Settings. → Sound. → Media volume and move the slider to the maximum.
• 🔊 Turn on the option Safe Volume (if any) and set the limit to 100%.
• 🎧 In the Mi Earphones app (download to Google Play), go to Headphone Settings → Sound. → Equator and select Preset Bass+" or "Rock" -- they turn up the volume.

On the iPhone:

• 🍎 Go to Settings. → Music. → Equalizer and select "Late Nights" (intensifies low frequencies) or "Rock".
• 🔇 Turn off volume limit in Settings → Sounds, tactile signals → Hearing safety.

💡

If the sound is quieter after connecting Buds 3 to a new smartphone, reset the headphones to factory settings: press both touch panels for 10 seconds until the indicator flashes red and white.

Method 2: Change the bluetooth codec and transmission protocol

By default, Xiaomi Buds 3 uses an SBC codec, which is compatible with all devices, but limits the volume and sound quality. If your smartphone supports AAC or aptX, switching to them can give you a 10-15% increase in volume.

How to change the codec:

1. On Android (with Developer Options support): Settings → About Phone → Assembly Number (tap 7 times) Settings → System → Developer Settings → Bluetooth Codec → Select AAC
2. On the iPhone, the codec changes automatically, but you can forcibly disable SBC if you turn off and reconnect the headphones in the “High Quality” mode (in Bluetooth settings).

Check out the Bluetooth protocol version:

• 🔄 If your smartphone supports Bluetooth 5.2+, Headphones are connected to 5.0, update the firmware of the phone.
• 📡 In the Mi Earphones app, update the headphone firmware (if available).

Method 3: Modification of the firmware headphones (for advanced)

Changing the system files of the Xiaomi Buds 3 firmware can increase the volume by 30-40%, but violates the warranty and risks bringing the headphones down.

The modification will require:

• 💻 PC Windows/Linux and installed by Python 3.8+.
• 🔌 Type-C cable for connecting headphones in firmware mode.
• 📂 Archive with modified firmware (see forums) XDA Developers or 4PDA Xiaomi Buds 3 loudness mod").

Step-by-step:

1. Download the utility. xiaomi_buds_flasher GitHub.
2. Connect your headphones to your PC in firmware mode: Press both touch panels for 15 seconds until the red light light lights up.
3. Start the command: Python flasher.py --device buds3 --file firmware_mod.bin
4. Wait until the end (the headphones will reboot).

⚠️ Attention: Modified firmware often disables overheating protection of speakers. With prolonged listening at maximum volume, the membranes can deform.

Method 4: Physical cleaning and hardware improvements

If the software methods didn't work, the problem could be contaminated speakers or bad fitting of earbuds, and over time, earwax and dust accumulate in the headphone grids, which drown out the sound.

How to Clean Xiaomi Buds 3:

• 🧼 Remove the silicone bottles and rinse them with warm water and soap.
• 🔍 Carefully remove dirt from speaker nets with a toothpick (do not use metal objects!).
• 💨 Blow the headphones with compressed air (a canister for cleaning equipment).

For advanced users, there is an option to replace the earpieces with a better soundproofing model (such as the SpinFit CP100+), which will increase the volume due to a better fit to the ear.

Make sure the headphones are off |Take off the earbuds carefully, don't pull the wires |Do not use alcohol or acetone to clean the plastic |Test the tightness after assembly-->

⚠️ Warning: If the sound gets worse after cleaning (wheezing, distortion), you probably damaged the speaker membrane.

Method 5: External sound amplifiers and uniform equalizers

If all previous methods failed, there are two options: use an external Bluetooth amplifier (e.g. FiiO BTR3K) or set the system equalizer to maximum gain.

The best Android apps:

• 🎛️ Wavelet (with support) ViPER4Android) — It allows you to raise volume by 6 dB without distortion.
• 🔊 Equalizer FX — Simple equalizer with presets for Xiaomi Buds.
• 📈 Poweramp Equalizer – Advanced settings for each track separately.

There are few alternatives on iPhones due to the limitations of iOS, but you can try:

• 🍎 Boom 3D — Enhances sound through virtual surround.
• 🎧 Enable “Bass Enhancement” in Apple Music Settings.

💡

External amplifiers (e.g. FiiO BTR3K) give the largest volume gain, but add latency when watching video.

Frequent errors and myths about increasing volume

You can find dozens of tips online that not only don't work, but they also hurt your headphones.

Myth 1: “Warming up your headphones at maximum volume improves sound”

❌ Reality: This leads to deformation of membranes and shortens the life of speakers. Xiaomi Buds 3 does not need "rocking" - their sound is optimized in the factory.

Myth 2: “You can turn up the volume by turning off one earphone.”

❌ Reality: Buds 3 uses dual speaker technology – turning off one headphone will not amplify the sound in another, but only violate the stereo effect.

Myth 3: “Firmware updates always increase volume”

❌ Reality: Most often, updates, on the contrary, reduce the maximum volume to meet European standards (directive). EN 50332-2).
