Generally, I am not a great connoisseur of sound, but (1 week of use) I find the speakers excellent! I use them on my PC, until now I had the Edifier S330D 2.1, and I find that they have excellent bass (very powerful even at moderate volume) and treble. I think that in order to increase the midrange, I need to adjust the equalizer, but even in the videos I played with the default EQ, the sound of the voice (mainly midrange) is clear. I haven't tried high volumes yet, but even at medium volume, I don't find any difference in sound quality. As for the design, needless to say, I love it (one of the main reasons I bought them), the construction is sturdy, they don't easily fall despite having a relatively small base. They are quite heavy compared to the previous ones I had.
