I think this is a nifty little trick to know, if the hearing between your ears is not the same.
If the hearing on your right and left ear differs, when you listen to music using earbuds or headphones, you’ll find that the quality of sound isn’t optimal. If you can get the balance correct, you’ll find that music sounds more full, and has more depth. I’m sure this is also possible on Android, but these are the steps for an iPhone:
Go to settings >
Select General >
Select Accessibility >
Scroll down to the section called “Hearing” and adjust the balance between the channels using the bar at the bottom of this section.
Enjoy!
PS, if you need some help doing this pop in and I’d be happy to help.
