This setting has been around for a while, but it’s subtle enough to have slipped through the cracks for many.
Take a look at this tweet.
To see this setting at work, fire up some relatively loud music on your iPhone.
Now go to Settings, scroll down to Music, make sure EQ is set to off. Get a sense of the volume.
Now scroll down and select the Late Night EQ setting. Notice a difference? To me, the difference is significant, the quiet elements boosted, the overall impression louder.
If you don’t hear a difference, tap to turn EQ off, then go back to Late Night. It’s subtle, but a good tip, worth sharing.
