How to turn off stereo on Xiaomi: a complete guide for all devices

Stereo sound on Xiaomi devices is a feature that creates surround sound by splitting the audio stream into left and right channels. However, in some situations, users want to switch to mono mode: for example, when using a single earphone, for people with hearing impairments or when connecting to external speakers that do not support stereo. In this article, we will discuss all possible ways to turn off stereo sound on Xiaomi TVs, smartphones and tablets, including hidden settings and alternative methods.

It is important to understand that the interface and location of options may vary depending on the device model and firmware version (MIUI, HyperOS, Android TV). We will look at universal solutions, as well as specific instructions for popular models such as the Mi. TV Q2, Redmi Smart TV X, Xiaomi 13 Pro and others. If you do not find your model in the article, use the general recommendations or check the relevance of the firmware.

Before you start settings, make sure that the problem is stereo sound, not hardware malfunction speakers. To do this, test the device with different audio sources (for example, YouTube, Netflix, local files) and check whether the effect is maintained when connecting external headphones or speakers.

Why would you need to turn off stereo?

The default stereo feature is activated on most Xiaomi devices, as it improves the perception of music and movies, but there are several scenarios where mono mode becomes preferred:

• 🎧 Using a single headphone (for example, when playing sports or while talking on the phone).
• 👂 Hearing impairments where stereo perception causes discomfort or dizziness.
• 🔊 Connecting to external speakers or amplifiers that do not support channel separation.
• 📺 Viewing content with poorly mixed sound (such as old movies or streams with unbalanced channels).
• 🎮 Game consoles or retro consoles where mono mode reduces sound delays.

Also on some Xiaomi TV models (e.g. Mi) TV 4S or Redmi Smart TV A Series) stereo sound can create a split voice effect in dialogs if the device does not correctly recognize the format of the audio track. In such cases, switching to mono helps to eliminate the problem without additional equalizer settings.

⚠️ Note: On devices with Dolby Atmos or DTS:X Turning off the stereo can automatically reduce the sound quality. If you're interested in volume, try adjusting the channel balance in your audio profile settings first.
