If you're one of those people who like their music as loud as possible, and you're stuck using the built-in iPhone speaker, then this trick might just be a blessing for you. Now be advised - this trick won't result in volume level that would make Pete Townsend smile, but it will (has been confirmed) to make your music play at least a bit louder.
I locked myself in a room and tried it with Beyoncé, Big Sean, and SZA, so I deduce that my scientific af experiments were conclusive enough.
Plus after seeing the tweet, a bunch of people also tried it and agreed that their ears were being blessed thanks to this discovery.
If you'd like to try the trick yourself you can find the complete instructions right here. And let us know in the Comments if it works.
