How to connect wired earphone with lightning connector to IPad Air with USB-C port?

Hey Ron!

Thank you for using Apple Support Communities! You'd like to connect your iPad Air with wired headphones. We know the adapter that you'll need.

To connect an iPad Air with USB-C to headphones you'll need a USB-C to 3.5 mm headphone adapter: USB-C to 3.5 mm Headphone Jack Adapter

Hoping that helps you out! Wishing you the best, be well!
