JBL Boombox 3 vs JBL Xtreme 4

The JBL Boombox 3 and the JBL Xtreme 4 share a similar look that's derived from their distant ancestor: the original boombox. For all intents and purposes, the Xtreme 4 is a paired-down version of the Boombox 3 that sacrifices a more balanced sound and dynamics performance for a smaller footprint and lighter construction. The Boombox 3 is three times heavier and takes up too much space to fit in most bags. However, opting for the larger speaker rewards you with richer bass and smoother highs, as well as a louder max volume with less compression. The two have a very similar battery life, though the Boombox 3 requires AC power to charge, as opposed to the Xtreme 4, which can charge via USB.
