Attach the Lightning connector to your iPhone, and the 3.5 mm aux jack to your car stereo or a home speaker system for a simple, one-cable connection.
How do I connect my 3.5 mm jack to my iPhone 8?
Apple's Lightning to 3.5 mm Headphone Jack Adapter is all you need. Plug the adapter into the Lightning port on the bottom of the iPhone 8, and then plug any headphones with a standard headphone jack into the other end. Like with headphones connected to a standard headphone jack, you don't need to change any settings.Jun 18, 2021
