A satisfactory quality product. I plugged in my laptop and I listen ASUS, depending on the mood or the TV news, or classical music, rock, jazz or variety, or video published online (super-cars recordings steam trains, nature sounds ...). No complaints about that side. For an article at that price, I am fully satisfied. The small carrying case is more significant. A note however: The dimensions given on the site made me think before I decide: Height = 79 cm, width = 161 cm! OUPSSSS! Frankly, I feared for a moment that it does not fit in my office! The actual dimensions are as follows (in millimeters, I specified in advance): Height = 161 mm; Width = about 67 mm; Depth = about 65 mm ... There, I said it! Thank you!
