What reviewers say

Reviewers praise the portable design and punchy sound. SoundGuys finds clear vocals; TechRadar hears a muddled midrange. SoundGuys reaches the claimed battery life at moderate volume, but far less at maximum volume. Its editor also reports a sample failing after brief immersion, despite the IPX7 rating.
