Ultimate Ears Wonderboom 4

The small speaker to take on the water. The Wonderboom 4 floats, so a slip off the dock or out of a canoe ends with it bobbing on the surface rather than resting on the lake bed, and it is drop-tested from 5 feet as well. The Outdoor Boost button tunes it for open air, where sound spreads out with nothing to bounce off, and the rated battery is 14 hours over USB-C. Bass is modest at this size, which also keeps it friendly to the neighbors on the next site.
