Verdict

The Anker Soundcore Boom 3i is a compact, ultra-durable 50-watt portable outdoor speaker featuring Bluetooth 5.3 and BassUp 2.0 technology that delivers punchy lows down to 56 Hz. It boasts an exceptional IP68 waterproof and dustproof rating, advanced 5x saltwater corrosion resistance, and an industry-first floating playback design that keeps the speaker upright and sound-forward in water. Key advantages include a robust 16-hour battery life, integrated customizable RGB lighting, a detachable shoulder strap, and smart utility features via its companion app, such as a 96 dB emergency alarm and a Buzz Clean debris-clearing vibration mode. However, notable drawbacks include its tendency to downmix stereo audio into a directional mono soundstage, a loss of sub-bass impact under heavy low-frequency demand, and a lack of a built-in microphone for phone calls or voice assistants.
