Pros excellent sound though im not what you would call an audiophile but i do find many lowerend speakers sound bad to my ears great price fairly easy setup great convenience and portability due to the battery perfect sound synchronization when used with other jongos as part of a wholehouse sound system i never detect any echolike sound and flexible as you can stream to it via bluetooth wifi and even wired with the purchase of a cheap about 10 usb to ethernet dongle
