Can you use lightening headphones on any iPhone?

[Jayson A]

I ask because I didn't know if the 7 had some sort of special lightening port for the new headphones/adapter.

 

[Macalway]

Yes. Just an adapter.

It converts irrational to rational.

I don't believe they will fit inside of an iPhone 4s or earlier.

Looks like the same old Lightning port. iPhone 5 or newer.
