iPhone 7 Will Ditch 3.5mm Headphone Jack To Shed A Millimeter Of Fat
The standard 3.5mm headphone ports have been ubiquitous on almost all entertainment devices - from headphone and tablets to televisions. Apple's designers are likely to replace that port with one port that does it all - the Lightning port. It will allow the iPhone 7 to be the thinnest phone in the entire iPhone lineup. Expect the iPhone 7 to be a millimeter thinner than iPhone 6s.
The Japanese blog also informs that Apple will introduce new earpods that will use the Lightning port. Apple may launch adapters or dongles that will allow you to use your old headphones with the new iPhone. But as of now, it all stands in the rumor zone.
There are strong points favor of the rumor. First of all, Macotakara has a history of leaks that have proven to be true. It means there is a 'high chance' of iPhone 7 shipping without the headphone jack. Last year, Apple had introduced the new MFi (Made for iPhone) specifications to the audio gear manufacturers that make way for the Lightning based headphones to replace the regular 3.5mm headphone jacks.

The specifications hint at two possible configurations for the new headphones - 'Standard Lightning' is the one that requires minimum components when hooked to digital to analog converter. The 'Advance Lightning' headphones would offer richer round with active noise cancellation, a technique that allows real time filtering of surrounding noise to deliver pure sound.
Apple's been ditching ports from their machines since last few years. The latest 12" Retina Macbook ditched all the USB, Networking and memory slots in favor of a single <a href="https://www.crazyengineers.com/threads/usb-type-c-explained-along-with-its-significance-in-modern-electronics.78113">USB Type-C Explained Along With Its Significance In Modern Electronics</a> port that does it all.
That said, Apple isn't the industry leader in ditching the headphone jack from their smartphone. That credit goes to HTC, which dropped it from their G1, an Android phone. However, when Apple does it, the industry follows. This could just be the beginning of the end of the 3.5mms.
We'd like to know from our fellow engineers whether they support ditching of headphone jack from the next iPhone. Is the headphone jack worth the sacrifice in order to make the phone thinner? We look forward to your opinions.
