An Apple patent published in September 2010 revealed the company was working on a new headphone jack design that would allow to place significantly smaller headphone jacks in future iPhones and iPods. According to Kevin Fox at Fury.com, Apple might have implemented the new design in the iPad 2, which features a headphone jack to fit the iPad’s smaller form factor and it’s set “in to a steep curve”.
The original iPhone also placed the headphone jack on a curved exterior surface, but did so by insetting it, with the disastrous side-effect that only headphone plugs that strictly adhered to the spec would fit deep enough into the recessed space to complete the connection.
This time however it looks like there’s no recession at all. In fact, the opposite seems to be true: A plug fully inserted into the jack will have a surprisingly large portion of its ground ring (the outermost metal band) exposed to the elements.
