Mono audio and balance
Mono Audio combines the sound from the left and right channels into a mono signal played on 
both channels. This way you can hear everything with either ear, or through both ears with one 
channel set louder.
Turn Mono Audio on or off. Go to Settings > General > Accessibility > Mono Audio.
Adjust the balance. Go to Settings > General > Accessibility, then drag the Left Right Stereo 
Balance slider.
Subtitles and closed captions
The Videos app includes an Alternate Track button   you can tap to choose subtitles and 
captions offered by the video you’re watching. Standard subtitles and captions are usually listed, 
but if you prefer special accessible captions, such as subtitles for the deaf and hard of hearing 
(SDH), you can set iPad to list them instead, if they’re available.
Prefer accessible subtitles and closed captions for the hard of hearing in the list of available 
subtitles and captions. Go to Settings > General > Accessibility > Subtitles & Captioning, then 
turn on Closed Captions + SDH. This also turns on subtitles and captions in the Videos app.
Choose from available subtitles and captions. Tap   while watching a video.
Customize your subtitles and captions. Go to Settings > General > Accessibility > Subtitles & 
Captioning > Style, where you can choose an existing caption style or create a new style based 
on your choice of:
 
Font, size, and color
 
Background color and opacity
 
Text opacity, edge style, and highlight
Not all videos include closed captions.
