why do different parts of the song come out of the right and left headphone?

Question

I hope you understand what I mean. How is it possible that I hear the drums only in one ear and the trumpet in the other ear?

The other person explained it well. Just to add:

This is a comparison of mono vs stereo jack.

Mono = same sound on each speaker.

Stereo = possible different sounds on two speakers.

You can see that mono jack has one strip, and the stereo jack has two strips. The metallic part of the jack is conductive, and the strip separates different conductive parts that connect to different wires. That’s basically how you can send different signals to different speakers.
