I just picked up my Marshall Kilburn Bluetooth speaker today and all I can say is it is worth every penny and will fill up a room with amazing sound quality with zero distortion. I read lots of reviews on different bluetooth speakers under the $300 range and this one stood out in quality and looks. I picked it up in black.
