Our take on the Ultimate Ears WONDERBOOM 4 Wireless Bluetooth Speaker

The WONDERBOOM 4 is Ultimate Ears' small, round Bluetooth speaker built for outdoor use. It is drop-tested, floats, and carries an IP67 dust and water rating, so it survives pool edges, showers and dusty campsites. Sound is bigger than its size suggests, with a single 40 mm driver and passive radiators, but it is mono and has no app EQ or speakerphone. It suits people who want a tough, pocketable speaker for casual listening rather than room-filling stereo.
