Question: how to use iphone x headphones on macbook?
Answer: A Lightning-to–3.5mm audio jack dongle is included in the iPhone 7 box, so you can use that to listen to audio on your new MacBook Pro with your new Lighting earphones. Apple's USB-C to USB adapter, which is what you can use to sync your iPhone 7 to your MacBook or new MacBook Pro, is $19.
