You get an adapter when you buy an iphone 7 so you can still listen to music, but can you plug in non apple headphones in that adapter too?

Yes, It is just an adapter, the headphone brand makes no difference. All the headphones will send the same, if not similar, signal to the phone so if you have an adapter the phone can still receive these signals.
