Logitech S-100 BLACK 120V~60Hz Desktop Speaker System w/ Headphone Jack, same one selling on ebay for around $30 with tax and shipping, selling here for $10. Read below:
works sort of, may have a loose connection. Sound comes out from 1 speaker find, the 2nd speaker only has faint base sound. For example, I plug it with my laptop and play a fitness video. I hear the instructor talking and music from the speaker that has power/volumn control and headphone jack clearly, but I have to put my ear close to the other speaker to hear just the beats. Maybe an easy fix if you know how to open it ans check the connection.
