Remember the guy who built an iPhone 6s from scratch using spare parts purchased in China, for less than half the price of a new one? Well, he’s back at it with another DIY mod which adds a fully functional 3.5mm headphone jack into an iPhone 7.

Those who don’t wanna pay $159 for AirPods or cannot be bothered to insert their headphones into an adapter every time they listen to music needn’t drill a hole in their iPhone.

iPhone enthusiast and world traveller Scotty Allen has taken upon himself to add a working 3.5mm headphone jack to his iPhone 7.

In Scotty’s own words:

In April, I decided to finally upgrade my iPhone 6s to an iPhone7 to get better camera quality for the videos I was shooting when I was out on adventures in the industrial markets and manufacturing world.

But I was super annoyed that it doesn’t have a headphone jack!

I already have headphones I liked, and I didn’t like the idea of having to keep track of an adapter just to use them. So I figured I’d add my own—after all, how hard could it be?

It turns out, really really hard. But possible.

Bringing his vision to life required courage and skills—he had to find chips that convert digital signals into analog audio, design his own circuit board, obtain access to expensive machinery to make it all work without any hiccups and more.

The project took much longer than anticipated: he’s spent the past four months in Shenzhen, China, modifying an iPhone 7 to add a fully functioning headphone jack. “To the best of my knowledge, this is the first time anyone has done anything like this,” he said.

So, how much did it cost him to make this a reality?

According to the man himself, he’s spent “thousands of dollars” on this project.

I’ve bought three iPhone 7 devices to take apart, a handful of new screens, several handfuls of backs I mutilated and countless other parts I broke. I paid a factory to do seven manufacturing runs of circuit boards. And, oh God the headphone adapters. I bought lots and lots of official Apple headphone adapters to take apart.

This is quite an impressive feat. I wish more enthusiasts engaged in DIY projects like Scotty but it’s understandable many don’t given the high price of Apple’s smartphone.

    So keeping an adapter attached your headphones so you can plug in the lightning port is hard to do ?

      I understand what you mean by saying that, and i tried to do the same, but if you have “favourite headphones” it means you use it on multiple devices, not just your iphone. which is why i don’t like it. it’s extra wear and tear unplugging and plugging, not to mention it’s a STUPID design to use the charging port to also transmit audio.

      • burge

        Ware and tear !!! and there you are plugging it in and out of multiple devices, Lol.


      No, keeping your adapter attached headphones plugged in while you charge your phone using the lightning port is what most people seem to be having problems with. I haver no dog in the fight though. I don’t use an iPhone.

        The thing is though the device is portable so why are you using it when it needs charging and you want to use headphones, Surely allowing it to charge up without you draining it at the same time means it’s gonna charge quicker. I just don’t see it as a problem as it’s a potable device and being such why now tether yourself to a wall socket.

        And this post thread was before the iPhone 8 and iPhone X so it’s not now an issue if you have one of these devices.

    Neat, but I haven’t missed the headphone jack myself.

  • They didnt put it there for a reason
    – they want us to start foucaing on the wirless and Bluetooth headset

      it’s a pity they didn’t focus on having affordable superior sound quality wireless headsets established along with fully supporting codecs across the board(this may be a stretch) prior to the 3.5mm jack iremoval.

    wow nice 🙂 but wireless is future

    • Paul

      no it isn’t. CDs weren’t the future either. nor were MP3s. a serious musician won’t use wireless, or compression. Wireless is annoyingly inaccurate.
