The speaker has a size for the good, albeit very bassy sound. The volume is also alright. The best thing however, is that you can use it not only as speakers but also as a Bluetooth receiver. I've got my foot facility connected with a jack cable to the Jukebar and can now from your iPhone music on this stream. This is not possible with many (too expensive Bluetooth speakers). The battery lasts very long. In addition, a mini-USB to Micro USB adapter is included. The constantly flashing blue LED is not optimal, but are not star deduction, because the product for this price is unbeatable.
