Our Verdict

Ultimate Ears WONDERBOOM 2

Marshall Willen

The Ultimate Ears WONDERBOOM 2 is better than the Marshall Willen. The Ultimate Ears is another small, portable Bluetooth speaker, but its build feels more durable than the Marshall. It reproduces more low-bass, too, and its 360-design provides a better soundstage.
