Back at IFA 2012, Logitech unveiled its new series of Ultimate Ears accessories. Among those were a couple of portable speakers: the Boombox and Mobile Boombox. I've spent the last few weeks using both, and have been quite impressed for the most part. Without giving too much away right off the bat, both units sound surprisingly good compared to Logitech's previous Bluetooth speakers (and the competition), and are priced pretty aggressively for the features offered.
