A quick tip for iOS users. It’s possible to view the dB level that is currently being produced by your headphones at any time on iOS. This is useful if you want to make sure that your headphones don’t get too loud.
To view the decibel level, you’ll first need to add the “Hearing” widget to Control Centre. You can do this by going to the Control Centre menu within the Settings app. Once you’ve added Hearing, the next time you swipe open Control Centre and select the newly added widget, you will see live a dB meter beneath the name of your headphones.
