Hello Geovision, iphones no longer have a 3.5 mm jack since iPhone 5 - i.e. since 2012. But since then there have also been the following accessories (https://www.digitec.ch/de/s1/product/apple-lightning-auf-35mm-kopfhoereranschluss-adapter-lightning-35mm-mobilgeraet-adapter-5897235) where you can still use any headphones with a 3.5 mm jack on your iPhone. If you want to charge and listen to music at the same time, there are also combination adapters.

that's over, but also with new phones from samsung.
