    TechRadarRated 4.5/5 · Hands-on review

    A punchy, tough, long-lasting speaker called one of the best at its price, held back only by being a small upgrade over the cheaper Wonderboom 3.

    Tech AdvisorRated 4.5/5 · Hands-on review · 2024

    An excellent rugged speaker with strong sound and long battery life; only a minor update over the previous generation but still near the top of the class.

    Tom's GuideRated 3.5/5 · Hands-on review

    Recommended for big sound from a small body, but it distorts at high volume, the EQ modes are weak and it is a modest update.

    A durable, portable speaker that is a safe buy but offers few upgrades over the Wonderboom 3.

    TechGearLabHands-on review · 2026

    Very durable and long-lasting, but sound is only average, loud volumes distort and the testers call it overpriced against rivals.

    Picked as the most waterproof portable speaker because it floats, and the writer praises its loud, compact build.
