Short answer: the Soundcore Rave, mainly on price, though neither ranks well in its class. It claims a 20,000mAh battery for 24 hours at $220 against $429 for the Sony GTK-XB90, a $209 gap. Both are short on real bass: the Rave has a pretty big lack of deep bass and rolled-off treble, while the Sony’s EXTRA BASS is muddy and not deep, with a weird midrange peak and strange overall tuning. Both are rated below 3.0/5 among the 43 party speakers; for better sound, the JBL Partybox Stage 320 ranks #3 at $499.95.
Buy the Soundcore Rave or the Sony GTK-XB90, whichever you find used in better condition; both are discontinued. For a new speaker, start with the JBL Partybox Stage 320 instead.
