No, unfortunately not, as far as I can remember. I would generally advise against buying these headphones. I bought them several times because I liked the sound quality and the design-related shielding of external noise, but the headphones always broke after a few weeks. And this despite the fact that I was actually quite careful with them.

No, the Koss The Plug Colors headphones have a 3.5 mm jack plug. However, here you will find 4 headphones that have an iPhone connection.
