The first ever portable speaker we reviewed from Sony, the SRS-X3, had some of the best sounding bass we've ever heard, but it also left us wanting a little more. The new SRS-X55 is the slightly larger cousin of the SRS-X3/X33 that is surprisingly inexpensive considering the fact that is sounds so good...although not perfect. It's one of Sony's smaller, compact portable wireless speakers to boast refined audio performance and a bunch of drivers that spit out powerfully loud 30W audio in a true 2.1 channel arrangement. It even rivals Bose's similarly sized Soundlink 3 at nearly half the cost. So is the SRS-X55 worth buying? Let's take a closer look!
