The iPhone 7 doesn't have a headphone port, which means you have to use special headphones or an adapter.
This should go without saying, but there's no headphone jack hidden inside your phone. So if you drill into your phone, you're just going to ruin it. It's not a "lifehack."
Internet pranksters are making viral memes suggesting that users take an electric drill to their new devices. And unfortunately some people are falling for it.
The video from TechRax at the bottom of this post has veen viewed nearly 10 million times, and the original concept started as $4.
There's no evidence that people are actually ruining thier new Apple products, unless $4 as proof.
If you're still curious about what's actually behind the speaker grill where the headphone jack used to be, you don't have to ruin your new device. $4 containing a "barometric vent" is hidden behind the metal.
Again, the following images and video are fake. They're pranks. Please don't do this.
