Both accessory-maker Belkin and Apple offer a solution to this problem, but neither provides users with a good experience.
Apple’s solution, according to an email response from Apple marketing exec Phil Schiller, is the company’s Lightning Dock. This flat, elongated platform connects to the Lightning port and offers both Lightning and 3.5mm audio ports on its back.
Aside from the fact that placing ports on the back makes them harder to use, this dock isn’t a full-time solution either. Using 3.5mm headphones and charging your phone at an airport or coffee shop can be complicated enough as is — do you really want to also have your phone on an upright stand where it can fall over, or worse, get snatched?
“Courage.”
