While a lot of this is fear-mongering nonsense, some of what Gordon Kelly puts forward with regard to Apple’s potential use of the Lightning connector for headphones actually makes some sense:
Of more relevance to most people, however, is the new functionality it will bring. Headphones with a Lightning connector would be able to do more than lower/increase volume, end calls and skip tracks. There could be specific app control or even the ability to set a specific app to start when they are connected. Since the Lightning jack can also receive power, not just send it, you could still charge a device by connecting it to your headphones while listening to music.
Imagine a pair of headphones, say, Beats, that used their bulky size to an advantage: as a backup battery for your phone.
Now look at the bottom of you iPhone. What is the most obvious thing stopping the device from getting even slimmer? That 3.5mm headphone jack. I’m not saying Apple will ditch it anytime soon, but I do believe they will eventually ditch it.
