Step by step

1. 

   Open Accessibility

   Open Settings and tap Accessibility, below Xiaomi Account. On ours it was in the main Settings list, not under Additional settings.

   Done

2. 

   Open the Hearing tab

   Tap Hearing, the third tab at the top, between Vision and Physical.

   Done

3. 

   Turn on Mono audio

   Mono audio is below Beam for notifications: Combine channels when playing audio. It was off on ours. Tap the switch; it turns blue.

   Done

4. 

   Set Audio balance

   Below it, drag the Audio balance bar towards Left or Right, as Xiaomi says. The blue part shows where it is set: on ours it was filled to the middle, and shorter after we dragged it left.

   Done

5. 

   Put it back

   To undo it, drag the bar back until the blue part ends in the middle, and turn Mono audio off. Ours looked as it did at the start.

   Done

• No Hearing tab? Xiaomi's guide says to tap Hearing to adjust audio on the Hearing page. Ours had four tabs: General, Vision, Hearing and Physical. Source: Generic User Guide for HyperOS 3.0

If this does not work

• Sound louder on one side? Check Audio balance on the Hearing tab. The blue part should end in the middle, as it did on ours. Source: Generic User Guide for HyperOS 3.0
• One earbud quieter? Xiaomi's help for its Buds 5 Pro says to check in the Xiaomi Earbuds app that both earbuds are connected, clean dirt from the speaker holes and turn off Dimensional audio.

• Uneven in one song or video only? Xiaomi says the audio itself can have unbalanced left and right channels. Mono audio plays the combined channels, so turn it on.

About this guide

Xiaomi says Mono audio combines channels when playing audio. The Audio balance bar makes one side louder than the other.

The screenshots are from our Redmi Note 15 Pro 5G with Xiaomi HyperOS 3.0.308.0 and Android 16, in Light mode. We turned Mono audio on, moved the balance to the left, then put both back.

Good to know

Beam for notifications, at the top of the Hearing tab, uses the camera flash or colour beams on the screen as notifications arrive or the phone rings. Hearing devices said No hearing devices connected on ours.

Caption preferences, below, was Off on ours. For reading out text instead, see Select to Speak and text-to-speech.

In short: Settings, Accessibility, Hearing. Turn on Mono audio, or drag the Audio balance bar.
