Great speaker.

Great speaker with great sound. It sounds much better than either of my Bose Bluetooth speakers with much better low end and sparkling highs. It isn't cordless and it needs to be plugged into a power source to work, but the sound quality makes up for it.

The external box is large and heavy at 15 x 9 x 8.5 inches. The quality of this product is apparent as soon as the lid of the box is raised.

Well built solid feel; Good sound across bass and midrange; Fast Bluetooth connectivity
