Short answer: the Bose S1 Pro for better sound quality, the W-King T9 Pro for the lower price. The Bose S1 Pro ranks #16 of 50 party speakers at $699. The W-King T9 Pro ranks #35 at $171.49, $527.51 cheaper.
What the Bose S1 Pro offers: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 mic/line + 1 line/Bluetooth). Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Watch for: With full range music, it becomes distorted above ⅔ volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass.
What the W-King T9 Pro offers: 250W peak power, 120dB sound output with dual 6.5” woofers + dual 2.5” tweeters. Removable rechargeable battery allows continuous play via battery swapping. 12 custom bass settings for EQ adjustments by music genre. Music-synchronized LED lights (ambient to high-energy strobes). True Wireless Stereo for stereo pairing. Bluetooth 5.3, great customer service. Watch for: Sounds warm, somewhat gritty, not as detailed as higher ranked speakers
Buy the Bose S1 Pro if sound quality is the priority over the price, or the W-King T9 Pro if the price is the priority over sound quality.
