Short version: These two battery-powered bluetooth speakers are the first modern boomboxes designed by the newly created subsidiary Logitech UE. Acquired in 2008, Ultimate Ears is well-known for its in-ear monitors used by many musicians in concert, not for its speakers. Even though the Logitech UE Mobile Boombox is limited, it is no surprise given the entry-level pricing. The real surprise comes from the big brother, the Logitech UE Boombox.
