Lightning Plug Earphones Into 3.5mm Plug (Earpods)

Hello,

I have a technical question:

I own an Ipod nano 7 generation on which you can listen to music with headphones that have an aux 3.5mm headphone jack connector. I have a few spare earpods from other apple products available at home, but newer earpods have lightning connector headphones.

I'm wondering what kind of adapter do I need to buy to be able to connect newer headphones to the Ipod nano 7 gen.?

Thanks

Simona
