I ordered these speakers for my computer. The rest was pleasant to listen and not sizzling. These tiny Logitech Z 120 in terms of power is more than enough. The + they save an electrical outlet by feeding through a USB port, so no bulky transformer problem (they turn on and off with the computer). The've purchased for their price, design their very discreet size and USB connections. But I did not expect such a quality sound for such speakers. A very good product Logitech, well packaged and delivered quickly.
