    A solid recommendation for a compact, rugged speaker with big bass, though changes from gen 1 are minor and features are basic.

    TechGearLabHands-on review · 2026

    Tested hands-on and ranked first of 14 Bluetooth speakers, it earns a clear recommendation for balanced, vocal-friendly sound in a tiny, tough body.

    Named the most versatile pick in a tested roundup, with adaptive sound and voice features, though it barely differs from the first generation and is not the overall winner.
