I bought these speakers for my laptop, because the built-in speakers are really useless, although they already belong to the better. I have to read through the previous reviews. Despite also poorer reviews I bought these speakers for a good price. For me, the boxes do exactly what I expected of them: they deliver for this price range a super sound. For a PC system also bass and treble are fine. The bad reviews in this direction, I would like to say the following: What do you expect from a complete sound system that just 35, - costs? If I want to enjoy my music and films in good sound, I do it myself on my couch in the living room comfortably and turn on my system, which precisely gives me this Super Sound. For that I got paid for it as well 20 times !! To times in between listening to music on a laptop, or even to enjoy a movie, these boxes are for me perfectly fine. People who expect more must grab hold deeper into their pockets.
