Chuck dealing with the removal of the 3.5mm input jack on new Apple products!  This adapter allows you to plug your headphones into a 3.5mm jack at the same time as plugging in your lightning cable to charge your device.  Unlike many other adapters that don’t sync or charge properly, this is MFI certified and meets Apple’s specifications.  Designed for products using lightning cables and that no longer have the 3.5mm AUX input.
