Very nice, compact speakers with good sound, very fast delivery. A couple of problems though. They don't switch off the PC speakers when you plug them in, as you might expect (e.g. with headphones in the audio jack). You have to restart the audio application. Even then they sometimes don't work (no sound, or no control via the multimedia buttons) and you have to switch audio preferences manually (and then switch back when you unplug them). The multimedia buttons themselves are unpleasant to use - hard and unyielding, with absolutely no tactile feedback - you can't tell if they are working or not. According to the manual only the mute button and volume controls work with all applications - the others may or may not be supported.
