As for iems they have there perticular quality as like being a microscope to music. But they lack the depth and and resolution thT the other two can give you. And speakers give you the best image as well as the most resolution of all. I too use to think like you until I got better cans and DAC. But it's all good as we just love this hobby and the enjoyment it gives us in both listening and interacting with others in it as well.
