Open Settings > Accessibility > Audio/Visual. Turn on Mono Audio. Audio from both channels is combined into a single signal. Optionally, use the Balance slider to adjust volume between the left and right sides.
Mono Audio
Merges left and right audio channels into a single combined signal.
What does this setting do?
Mono audio ensures that all sound information is heard equally in both ears, regardless of stereo separation. This is especially useful for people with partial hearing loss, auditory processing challenges or difficulty focusing when audio is spread across channels. All major operating systems provide this feature.
Instructions for different systems

Often mentioned in relation to the following conditions:
- Mild Hearing Loss – Difficulty hearing quieter audio cues, voice messages, or notifications.
- Tinnitus – Sensitivity to audio notifications or constant noise leading to concentration difficulty.
- Auditory Processing Disorder (APD / AVWS) – Difficulty processing auditory information, especially inconsistent or complex sounds.
- Anxiety Disorder – Heightened sensitivity to sudden changes, alerts, flashing content or notifications.
- Age-related Cognitive Changes – Slower processing, reduced working memory, and difficulty with complex navigation.
Commonly used for the following difficulties:
Mild Hearing Difficulty
Users with reduced hearing may miss quiet alerts. Louder tones, balanced audio, or visual cues can support recognition.
Sound Sensitivity
Sudden or loud system sounds can be uncomfortable or overwhelming. Lowering volume, reducing alert sounds, or enabling vibration-only modes can help reduce stress.

Relation to WCAG guidelines
For setting to be effective, a website or app often must be technically implemented in such a way that it respects operating system and browser settings.
Developers and designers should follow the Web Content Accessibility Guidelines (WCAG). The following WCAG criteria are particularly relevant for this setting:
