Verdict

The boAt Stone 650 is a portable wireless speaker equipped with dual 2-inch dynamic drivers delivering a 10W RMS audio output and an impedance of 4 Ohms. Encased in a protective silicon body with a diamond-gridded mesh, it features an IPX5 water and dust resistance rating, weighing approximately 655 grams. Key performance strengths include a dedicated passive bass radiator for enhanced sound depth, multi-connectivity options via Bluetooth, a 3.5mm AUX port, and an SD/TF card slot, alongside a built-in microphone for hands-free calls. Powered by an 1800mAh lithium-polymer battery, it delivers up to 7 hours of continuous playback on a 60% volume level, though it requires a relatively lengthy charging time of 3.5 hours via an older micro-USB port, and exhibits notable sound distortion at maximum volume thresholds.
