Hello, I do not know if the question is in a good section, please move in case of problems. I stumble on various topics related to it all the time, but I can't find a uniform and consistent answer. Can I play with a 3.5mm jack to listen to music, e.g. from a smartphone or mp3? from e.g. using: Gembird Jack Stereo 3.5mm audio adapter can someone explain it to me and write or explain how it can be done or bought? thank you greetings
