Short answer: the Sony SRS-XV500. It ranks #16 of 44 party speakers by sound quality (rated 4.0/5) at $315 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 Sony SRS-XV500 is the better-sounding, longer-running choice. RTINGS measured a slightly warm sound with plenty of bass punch, and found it gets very loud for outdoor parties. It is rated for 25 hours of battery against 18 for the Samsung MX-ST50B. The catch: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides.
The case for the Samsung MX-ST50B: A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. The tradeoff: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
Buy the Sony SRS-XV500. It is rated higher for sound quality, and the Samsung MX-ST50B is discontinued, so it is only available used.

The Two Speakers In Full
Sony SRS-XV500: $315.00 Amazon eBay
Older model: the Sony SRS-XP500 (ranked higher, rated 4/5).
Pros: RTINGS measured a slightly warm sound with plenty of bass punch, and found it gets very loud for outdoor parties. Two 140mm woofers and two 60mm tweeters in a bass reflex cabinet, with a claimed 25 hours of battery life and a 10 minute quick charge for about 2.5 hours of play. Two 6.3mm inputs switch between microphone and guitar, with karaoke controls for key, echo and per-input volume, plus a 3.5mm aux input. IPX4 splash resistance and built-in lighting.
Cons: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides. Bass compresses and pumps as you approach maximum volume. At 11.2 kg it is heavy to carry, and IPX4 only covers splashes.

Samsung MX-ST50B: $300 Discontinued Amazon eBay
Pros: A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. Hands-on reviews find it capable of clear, punchy sound and impressive output for indoor parties, while its 18-hour claimed battery supports more casual use away from mains power.
Cons: Output drops sharply to 90W on battery, so it needs mains power for its full impact. Bass is not as deep as stronger dedicated party speakers, and at 11.9kg its tall enclosure is less convenient to carry. It lacks TWS stereo pairing, so the Group Play feature favors shared party coverage rather than a conventional stereo image. Discontinued.
