Verdict

The Harman Kardon Go + Play 3 is a premium portable Bluetooth 5.2 speaker featuring a 160W RMS three-way audio system composed of two 20mm tweeters, two 2.75-inch mid-range drivers, a 5.2-inch downward-firing subwoofer, and dual passive radiators. Main characteristics and pros include its elegant design with a tempered glass touch panel and aluminum handle, a built-in battery delivering up to 8 hours of playtime, multi-device pairing, automatic room self-tuning, and dual far-field microphones for clear calls. However, notable cons include its lack of an IP rating for water or dust protection, the absence of a companion app for custom EQ adjustments, and its relatively heavy weight of 4.7 kg, which limits outdoor portability.
