Short answer: the JBL Partybox 330 for better sound quality, the W-King T9 Pro for the lower price. The JBL Partybox 330 ranks #1 of 46 party speakers at $629.95. The W-King T9 Pro ranks #31 at $171.49, $458.46 cheaper.
What the JBL Partybox 330 gets right: The top-ranked party speaker here, with a removable battery, handle and wheels, and dual mic/guitar inputs for karaoke and live sets. The catch: it’s very large, and JBL’s PartyBoost/Auracast daisy-chain only works with other JBL speakers.
On the W-King T9 Pro side: Costs less than half as much, with a removable battery of its own. The tradeoff: sounds warm and somewhat gritty, well behind the 330 on detail.
Buy the JBL Partybox 330 if sound quality matters more than the price. Buy the W-King T9 Pro if the price matters more than sound quality.

The Two Speakers In Full
JBL Partybox 330: $629.95 Amazon Bhphotovideo
Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.
Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
