What are you talking about? No it didn't. It came with an adapter that has a female 3.5mm headphone jack on one and and a male Lightning adapter on the other end to allow you to connect headphones with a 3.5mm connector to your Lightning-only iPhone 7. To connect to a 2016 MBP, you would need the opposite—a cable which does not currently exist.
No no, cust0m is right, I didn't think it through. It comes with a 3.5mm female to lightning male adaptor, not a lightning female to 3.5mm male adaptor.
