Great speaker product
Though a bit dated now, these harman/kardon speakers are reasonable priced for the quality it brings. They are two speakers that fit on your desktop using the standard 5mm input. It does need its own power supply, and on the front provides a 5mm jack that allows you to put your headphones when you don't want to have speakers on. Testing a headphones through harman/kardon and directly connected to the computer shows no noticable difference, so they're good for anyone that wants to just plug in front of their computer without needing to go to the back of the computer case. They provide the traditional stereo sound, and a knob for finer control of volume. It lights up when the speakers are on, and can be turned off by turning the volume knob all the way down with a audable click. There is a tone knob, but I don't know what it does; it never really did anything for me when I fiddled around with it. Overall, this is a decent set of cheap speakers.
