Jack-supported speakers can also be connected to USB devices that
implement the USB Audio class specification, and there are USB speakers
that also have analog inputs, so your question is somewhat meaningless.

If you want to compare analog speakers with USB speakers, the main
difference is that analog speakers require the computer to have analog
output jacks, while USB speakers can be connected to any computer with
a free USB port.  This allows upgrading (with more outputs and/or better
quality) the existing sound output, if any, especially on laptops where
adding a sound card is not possible.

USB speakers have the disadvantage that they work only with a computer.

Why are you asking this question?
