Jabra's footwear-inspired wireless Bluetooth speaker now comes in a jumbo-size model, the Solemate Max, which retails for $400. While it could sound a little cleaner and more detailed for the money, it plays very loud for its size, pumps out a good helping of bass, and is very well-built, with a ruggedized design that's water-resistant. It also offers good battery life (around 14 hours) and has speakerphone capabilities.
