Since I have recently acquired a speaker-less monitor, I was looking for suitable small speakers, but occasionally I like ending the computer work listening to music. Based on the positive reviews I decided to order 2er Edifier R600 USB boxes. Delivery promptly as usual. The surprise came after unpacking and connecting. It's incredible what these two - do boxing on a simple USB port - admittedly not very small. Crystal-clear and spatial sound to a simple USB connection, no power adapter required, amazing volume. Equally amazing the run with a test CD - from 60 Hz clearly audible signal - unusual for relatively small boxes, as well as organ music is perfectly listenable. My compliments to the developers of these boxes at this price!
