Short answer: the Sony ULT Tower 7 for better sound quality, the Samsung MX-ST50B for the lower price. The Sony ULT Tower 7 ranks #1 of 39 party speakers at $648. The Samsung MX-ST50B ranks #21 at $300, $348 cheaper.
What the Sony ULT Tower 7 offers: A compelling large-party value at $649.99: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. The full review praises its punchy, clean ULT1 bass, ULT2’s higher-output mode, simplified controls and unusually complete I/O: USB-C, USB-A, RCA, balanced XLR and mic input. Watch for: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers. IPX4 is splash resistance rather than full weatherproofing; the 30-hour claim requires lights off.
What the Samsung MX-ST50B offers: 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. Watch for: 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.
Buy the Sony ULT Tower 7 if sound quality matters more than the price. Buy the Samsung MX-ST50B if the price matters more than sound quality.
Battery life favors the Sony ULT Tower 7: rated for 30 hours against 18 hours for the Samsung MX-ST50B.
