Should you buy it?
Buy the Wonderboom 4 if you want a small, durable speaker for travel: reviewers praised its surprisingly rich, clear 360-degree sound, IP67 protection, a light, travel-friendly design with a loop, solid battery life, USB-C charging and fun colors. Skip it if you own the Wonderboom 3, because it's a minor upgrade. There's no app support or microphone, and the sound breaks up at high volume.
Best for
Travelers and poolside listeners who want a tiny, tough speaker.
Not for
Wonderboom 3 owners and anyone who wants app controls.
