Earlier this month Ultimate Ears unveiled the WONDERBOOM 2, a second-generation model of its popular portable Bluetooth speaker. A host of notable upgrades over the original model set it up to contend as one of the best in the competitive outdoor summer speaker category. Along with various improvements, like increased battery life and better waterproofing, UE has dressed up WONDERBOOM 2 in a handful of fresh fabrics. With warm weather here and the latest from UE by my side, Im been enjoying some tunes while testing out this new speaker. Head below for my WONDERBOOM 2 review.
