Engineer Brings Back the Headphone Jack to iPhone 7 [VIDEO]


Scotty Allen, an American engineer and hacker who has previously worked at Google and several other prominent Silicon Valley startups, and is also known for making an iPhone 6s out of spare parts, has returned with another project where he unveils how to bring back the headphone jack on the iPhone 7. Allen has spent the past four months in Shenzhen, China, and has successfully modified an iPhone 7 to add a fully functional headphone jack.

Here’s what he writes:

“I went through a ton of iterations and debugging to get this to work. The hardest parts were the electrical design and getting everything to fit inside the phone. Specifically, because I was using the logic from an Apple headphone adapter and a headphone jack from an iPhone 5, I had to find space to put them without breaking anything else.

I feel like I got extremely lucky about finding space inside the phone. There was inexplicably a lot of extra room in the lower left hand corner, right where I wanted to put the headphone jack. And because I was connecting the headphone adapter to the lightning jack, I needed to figure out how to make the lightning jack still work for things like charging and syncing to a computer”.

Allen has also made a limited edition board which allows users to insert a 3.5mm headphone back and Lightning cable all at once. You can learn more about it at this link. In the meantime, check out the following video and share your thoughts in the comments section.

    “There was inexplicably a lot of extra room in the lower left hand corner, right where I wanted to put the headphone jack.” You know Apple, if you hadn’t filled that space with air instead of a headphone jack, I would have bought an iPhone 7 last month instead of a 6s.

    Yeah, that’s cool. But what about that barometric sensor…?

    So much for the water proofing.

    It was never waterproof – just water resistant. And it gets worse with time. So he didn’t lose much.

    “iPhone 7 and iPhone 7 Plus are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear.”

    No need for Headphone Jack unless your Djing on a mixer not on a phone so dumb.
