This little sound bar is not what you might expect it to be as to my mind, a sound bar should provide a goodly amount of sound. This does not, hence the description above. It lacks something and that is volume and presence. The output is on a par with a portable radio. It should be better, especially as the monitors to which this attaches are of quite good quality and are not cheap. Having said that, you get what you pay for. This is a very cheap sound bar. Perhaps it should be cheaper, but that's down to Dell. It looks OK and it does the job up to a point. I would have preferred to spend more and get more, but that is not an option here. The power lead connect to the monitor power pass through and the audio lead connects either to your PC headphone socket, or to the monitor audio output if you are using HDMI as your connection method.
