What reviewers say
Reviewers agree it sounds rich and full for its size and is tough, portable and long-lasting on battery. All three note it is a small update on the Wonderboom 3, and TechRadar and SoundGuys regret the lack of app support; Tom's Guide found the sound suffers and the speaker vibrates at high volume, and the strap cheap.
