Pros: A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. An exceptionally rugged 380g mini speaker with IP68 protection, a floating sound-forward design, app EQ, RGB lighting, a battery display, USB-C power-bank output and Auracast/TWS linking. It reaches about 92dB and independent testing finds it lasts nearly six hours at maximum volume with lights and BassUp enabled, matching its demanding claim.

Cons: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic. It is directional by design, so the sound changes off-axis, and independent reviews note it lacks a built-in microphone; it is far better for rugged outdoor background music than a large gathering.

Setup: Try out Oluv’s EQ which slightly improves the sound
