Purchased following the sinking of a very very old PC. Logitech is a good brand, simple, not very expensive and sufficient quality for intensive use. Their predecessors lasted 9 years at home :) These speakers (white, cheaper and more original than black) allow sound to the PC (or any device 3.5 jack). Very nice sound, deep and enjoyable. Taken very useful for auxiliary and simple facade button. PC Connectivity and power supply. No complaints, a purchase for the long term.
