How to Make One Xiaomi Headphone Louder Than Another: All Ways

The problem of uneven volume in Xiaomi headphones is familiar to many users: one speaker sounds quieter due to factory defects, membrane wear or sound perception. Fortunately, you can correct the imbalance without going to the service center - just use built-in MIUI functions or third-party tools. In this article, we will discuss 5 working methods, including hidden settings, applications for fine-tuning the sound and even hardware solutions for older models.

It's important to understand that not all methods are universal: for example, volume balance in Settings → Sound is not available on all firmware, and some applications require root rights. We will specify the limitations for each method and provide alternatives. If you use Redmi AirDots headphones, Xiaomi Buds or a wired model, here you will find a solution for your case.

Before you start settings, check the obvious causes of the imbalance:

• 🔊 Mesh Pollution Speaker - Clean the headphones gently with a cotton swab.
• 🎧 Poor connection – reconnect your headphones or check the 3.5mm connector (for wired models).
• 📱 Software update – outdated firmware can knock down the sound settings.

1. Built-in sound balance setting in MIUI

The easiest way is to use standard MIUI tools, but this feature is not available on all firmware and smartphone models.

Open Settings → Sound → Volume Balance. If there is no point, try an alternative path:

1. Go to Settings → Special Opportunities → Hearing.
2. Activate the Mono-Audio option (this will combine the sound into one channel, but allow you to adjust the balance).
3. Return to Settings → Sound – now the balance slider can appear.

On Xiaomi smartphones with Android 12+ (for example, Redmi Note 11, POCO X4 Pro) the path may be different:

Settings → Connected devices → Headphones → Sound settings → Balance

⚠️ Note: Some models (e.g. Redmi) 9A) There's no built-in balance adjustment because of the simplified firmware. In this case, use methods 2-5.

Check the version of MIUI in Settings → About the phone

Connect headphones (wired or Bluetooth)

Make sure the volume is at maximum for fine tuning

Restart your phone if the sound disappears after you connect.-->

2. Applications for sound balance adjustment

If you don't have built-in tools, use third-party apps. We tested 3 of the most reliable options:

For most users, the best choice is SoundAssistant:

• 🎛️ Allows you to adjust the left/right channel balance in step 5%.
• 🔊 Works with Redmi AirDots and others TWS-headphone.
• 📱 Compatible with MIUI 12–14 without additional rights.

Instructions for setting up in SoundAssistant:

1. Install and open the application.
2. Go to the Sound Balance section.
3. Move the slider to the left (strengthen the left earpiece) or to the right (strengthen the right).
4. Save the profile for specific headphones.

⚠️ Attention: When in use ViPER4Android Xiaomi on Android 11+ You may need to disconnect MIUI Optimization in the developer settings. Otherwise, the sound driver will not boot.

💡

If the sound is hoarse after adjusting the balance in the application, reduce the overall volume by 20-30%, which will eliminate distortion due to channel overload.

3. Configure via the engineering menu (MTK/Qualcomm)

For advanced users, there is a way to adjust the balance through an engineering menu, which works on Xiaomi smartphones with MediaTek (Redmi 9, POCO M3) and Qualcomm (Redmi Note 10, Xiaomi 11T), but requires caution – incorrect settings can damage the audio system.

Instructions for MediaTek:

1. Open the Phone app and enter the code: ##36446337###.
2. Go to the Hardware Testing → Audio section.
3. Select LoudSpeaker Mode (for speakers) or Headset Mode (for headphones).
4. In the Left/Right Volume field, set values from 0 to 255 (e.g., 200 for the left and 180 for the right).

For Qualcomm, use the code ##4636##, then:

Phone information → Select “Audio” → Headset → Level adjustment

⚠️ Note: Changes to the engineering menu are not saved after rebooting on some Xiaomi models. MTK Engineering Mode (for MediaTek) with profile saving.

4. Hardware solutions for wired headphones

If the software methods didn’t help, and the problem is with Xiaomi wired headphones (such as Mi Basic or Redmi Hi-Res), check out the following points:

• 🔌 Wire damage - often rubbing at a plug or connector causes volume loss in one channel.
• 🔊 3.5mm connector fault – clean the socket of dust or try an adapter USB-C → 3.5 mm (for models without connector).
• 🛠️ Membrane repair – if the speaker is quieter due to physical damage, it can be restored in service (cost) ~500–1000 ₽).

For a temporary solution, use a sound amplifier (like the FiiO A1) connected between your smartphone and headphones to allow volume to be leveled by manually adjusting channel amplification.

How to check the wire on the cliff:

1. Connect the headphones to the PC and play the test signal (you can use this service).
2. Bend the wire at the plug and connector – if the sound appears / disappears, the cable is damaged.
3. For accurate diagnosis, use the multimeter in chain check mode.

💡

If headphones are guaranteed, do not disassemble them yourself - contact the Xiaomi service center. In 80% of cases, the volume imbalance is eliminated for free under warranty (provided there is no mechanical damage).

5. Features of settings for TWS-Headphones (AirDots, Buds)

Xiaomi wireless headphones (such as Redmi AirDots 3 or Xiaomi Buds 4) are regulated differently due to separate audio channels for each headphone.

• 📱 Mi Earphones is the official firmware and customization tool. Download it here.
• 🔄 Headphone reset — sometimes imbalances are due to sync failure. For reset: Put both earphones in the case. Press and hold the button on the case for 10 seconds (until the red light flashes). Reset the headphones to the phone.
• 🔊 Firmware update – check for updates in the Mi Earphones app. For example, AirDots Pro 2 patched balance bugs in version 1.4.0.
