Apple now sells an iPhone dongle with a headphone jack and charging port.
The new Belkin adapter is $35 and available at Apple retail stores
Apple took over year after the release of the iPhone 7 to start selling a dongle that lets you plug in headphones (or your car’s AUX cable) and charge at the same time. But now it’s here. Even if it’s not manufactured by Apple, I think it’s safe to say they are profiting from it.
