Short answer: the JBL Partybox Stage 320. It ranks #3 of 51 party speakers by sound quality (rated 4.6/5) at $499.95 and is still sold new; the Samsung MX-ST50B ranks #25 (rated 3.6/5) and is discontinued, so it is only an option used.
The JBL Partybox Stage 320 is the better-sounding pick. An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. The catch: Slightly sibilant in the treble at full blast.
The Samsung MX-ST50B is the lighter pick. A splash resistant party tower with two woofers, karaoke input, app EQ, and linking for up to ten speakers. At 26.2 lbs (11.9 kg) it weighs noticeably less than the JBL Partybox Stage 320 at 36.4 lbs (16.5 kg). It supports aptX Bluetooth, which the JBL Partybox Stage 320 lacks. Watch for: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
Buy the JBL Partybox Stage 320. It is rated higher for sound quality and still sold new, while the Samsung MX-ST50B is discontinued.
