It's pretty good, obviously not as good as high end speakers, but for the price (I got mine for £200) it's really good value and effortless to use. Main feature is it can adjust to any room or place you put it.
I find it bit bass heavy, though I prefer more neutral sound.
I bought it just for listening of music while I work and I'm very happy with it. I want to get another one to pair them into stereo setup.
