plays quite good. loud enough to fill the space. I expected it to rumble, but it didn't. The Bose Soundlink Mini is shown here speaking inaudibly against a black background. However, prior to it, it appeared as though there was only a full-fledged, deep sound. Of course, the middle and treble are lacking. Although Sony plays more consistently, it still lacks the strength and weight of Bose for obvious reasons. It's 4 times less expensive, so I won't be surprised.
