Short answer: the Soundboks Mix, if you are buying new. The Samsung MX-ST50B ranks higher than it (#25 vs #34 of 51 party speakers, 3.6/5 vs 3.2/5) but is discontinued, so only consider it used; the Soundboks Mix is still sold new at $799.
The Soundboks Mix is the longer-running option. A rugged, weatherproof party speaker with a swappable battery that runs all day at mid volume and fast USB-C charging. It is rated for 40 hours of battery against 18 for the Samsung MX-ST50B. The catch: Doesn’t have as deep of bass as higher-ranked speakers, and can sound somewhat bright in the treble.
The Samsung MX-ST50B is the better-sounding option. A splash resistant party tower with two woofers, karaoke input, app EQ, and linking for up to ten speakers. It has an adjustable EQ, which the Soundboks Mix lacks. It plays in stereo from a single unit, unlike the Soundboks Mix. The catch: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
Buy the Soundboks Mix, since the Samsung MX-ST50B is discontinued and only worth hunting down used.
