Short answer: the Samsung MX-ST50B on measured sound quality, the W-King T9 Pro on price. The Samsung MX-ST50B ranks #21 of 39 party speakers at $300. The W-King T9 Pro ranks #26 at $171.49, $128.51 cheaper.
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.
What the W-King T9 Pro offers: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. The swappable battery is especially useful for long events, and its strong output gives it much more headroom than compact Bluetooth speakers. Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed. Its claimed output figures should not be mistaken for neutral sound quality, and a large cabinet with no stated water rating is a poor fit for wet outdoor use.
Buy the Samsung MX-ST50B when sound quality outweighs the price for you, and the W-King T9 Pro when the price outweighs sound quality instead.
There is a real battery-life gap here: the Samsung MX-ST50B is rated for 18 hours, the W-King T9 Pro only 12 hours.
Water resistance is not close: the Samsung MX-ST50B is rated at IPX5 (water jets), well ahead of the W-King T9 Pro at no water resistance.
