Excerpt: Perfect little basic speakers dor portable or desktop. USB digital all the way so no "front and back" setup. For their size very good sound and they are built solid. Only thing that could be better is a bit more cable connecting the two so as to span two side-by-side monitors.
Summary: Volume buttons on the speak controls the system volume instead of the internal speaking like most others you would purchase. Doesn't really effect much, but it is something to mention. ALSO, DOES NOT WORK OUT OF THE BOX WITH LINUX. You will have to search the repositories for this one.
Pros: Had these things for years and still able to use them with an HTPC. A lot louder than you would expect, infact the lowest setting is still extremely loud - Easy fix is to lower the in-application-volume. USB powered makes it insanely great for cable management.
Cons: 1.2 W isn't enough for high end movies, but you should not expect much from a USB powered device.
