What to know before buying

The listing gives 180 Watts maximum output and a 20 Hz frequency response but provides no measurement conditions or response range. Treat these as unqualified listing figures, not a complete account of sound performance. Its 24-hour battery claim also has no stated playback conditions. The IP67 and other durability descriptions are manufacturer claims, not independently verified here.
