Verdict

The Kygo B9/800 is a versatile 20W RMS portable smart speaker equipped with dual 1.75-inch full-range drivers, delivering 360-degree omnidirectional sound with a frequency response of 75Hz-20kHz. Its primary advantages include dual-band Wi-Fi (2.4/5 GHz) and Bluetooth 4.2 connectivity, integrated Google Assistant and Chromecast for multiroom configurations, and a 2600 mAh battery providing up to 8 hours of playback. Additionally, it features an IPX7 waterproof rating and floats in water, making it excellent for outdoor use. However, notable drawbacks include a poorly positioned charging port on the top of the unit, elevated audio distortion at maximum volumes, and an automatic sleep mode that requires regular manual re-activation if left unplugged.
