The BassUp 2.0 technology with DSP processing doubles the bass response compared to the industry benchmark, producing punchy lows and crisp highs that cut through outdoor noise at the beach, poolside, or on the water. The compact water-bottle-sized body fits comfortably in one hand, clips to a backpack, or sits on a kayak deck without taking up space.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIP68 waterproof with floating playback and saltwater resistance:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe Boom 3i carries a full IP68 rating for complete dust and water protection, and goes further with saltwater resistance tested to 240 hours of salt spray, five times the industry average. The speaker floats upright in water with the drivers facing forward, maintaining clear audio playback even in waves. Unlike most waterproof speakers that sink or float sideways with the sound facing down, the Boom 3i auto-corrects to keep sound projecting upward and forward. The rugged casing with rubber bumpers survives drops from up to 1 metre.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e16 hours battery life with Bluetooth 5.3 and 100m range:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe integrated battery provides 16 hours of continuous playback on a single charge via USB-C.
