Short answer: the Soundcore Rave 3S. It ranks #19 of 49 party speakers by sound quality, rated 3.8/5, at $349.99. The W-King T9 Pro ranks #35, rated 3.0/5, at $171.49, $178.50 cheaper, which does not close the gap in sound quality.
The Soundcore Rave 3S is the better-sounding, tougher option. 2 AA battery Wireless Microphones and remote control included. It is rated IPX4, while the W-King T9 Pro has no water resistance. It links with other speakers (Auracast), which the W-King T9 Pro cannot. It has an adjustable EQ, which the W-King T9 Pro lacks. The tradeoff: Some upper bass and upper mids boost.
What the W-King T9 Pro does well: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. It plays in stereo from a single unit, unlike the Soundcore Rave 3S. Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the Soundcore Rave 3S. It is rated higher for sound quality, and saving $178.50 with the W-King T9 Pro does not make up for the sound-quality gap.
