"Very good" describes these speakers quite perfect. I bought them as a replacement for an old couple in my office. They play excellent music at high volume, but just as good at lower volumes too, which is important in an environment with other people around. The headphone jack on the side is also perfect, easily accessible when you need to listen to something more private, or do not want to disturb anyone at all. Withdrawals also for headset had been an added plus, but may lie outside this product's main area.
Speakers are plastiga, yet awe-heavy and stable. The volume button as well, it glides with some resistance but without squeaking or crackling, just as it should be. No risk of accidental pulls at full volume, simply.
The design is well what one would expect for around 400kr, but the shiny, black finish blends still well into the environment.
Plus for good sound, stable feeling, steady volume control and headphone jack accessible on the page.
Minus ... Not much at all, actually. For this price exceeds the actual expectations. After all, PC speakers this, nothing else :)
