solid piece of equipment for his desk, with clear sound and sound processing. only when you turn the sound up in music player and Windows on most volume is heard (of course), mainly in bass-heavy songs, a croak / noise. since you so a volume without hearing loss but only endures a short time, you will never use this in practice.
With the USB port of the speakers, this really can be used without problems for each system - infected and works, so must it be, and an unnecessary power cord for the power supply of the boxes is also absent. The USB cable is the way long enough, which is not visible on the product image.
In addition, the speakers are still delivered in a small black bag. A nice accessory to protect the speakers, if you want to transport them, otherwise the bag will disappear in the box.

EDIT: as some had to say reviewer before me, I also had the problem that the boxes too loud even at the lowest settings (eg background music) .. had the windows desktop knob all down here at 1% and the respective player ( Winamp, Media Player, or Flash videos on youtube), I had the regulator also almost to rotate at the bottom to achieve a not unpleasant loud volume - had returned the speakers, therefore,. I switched to the Philips spa2210 and very satisfied!
