When I ordered these speakers, I already owned on another pc. Suffice to say they give me complete satisfaction otherwise I would not have bought them. Plus: good bass present and that boost the sound. Beware though, in poor quality sound recordings (eg bootlegs or live video on the internet taken snatches of your favorite groups), saturation may appear, although rarely, however. Curiously, I got pregnant the second time start "standby" after an hour if there is no use (can be less than an hour, I have not rated), unlike the other speakers that I even if my computer goes to sleep. It is then renclencher the on / off button and you're off again. And here on this little flat button that is located rather badly since the subwoofer, which means we have to bend down to access what is impractical. This is the downside of it. Another little curiosity. Both my pc was one near the other, the speakers I recently bought react with a "pok" loud enough when I close my electric shutters or when I use my guitar amp beside. Not at all for others. Finally, I noticed at rare moments a blast on the left speaker but disappears when I fiddle with the bass button located on the right speaker. I think all these small anomalies that I did not with the same speakers are connected to the fact that this is a repackaged product thus "secondhand" (I paid obviously much cheaper these speakers) . In conclusion, I will say however that these speakers are excellent, however perfect but flat with the on / off button located on the box stupidly low.
