The Promate iHinge-LT aims to provide iPhones/iPads with a single Lightning port with the ability to charge, listen to music, or make calls simultaneously.

This compact 2-in-1 adapter splits the Lightning output into a dedicated charging port and a separate Lightning audio port.

Therefore, it allows you to connect the charging cable and headphones (with Lightning headphones) at the same time without having to choose one over the other.
