Short answer: the JBL Partybox 330, if you are buying new. The JBL Partybox 300 ranks higher than the W-King T12 (#10 vs #21 of 46 party speakers) but is discontinued; its replacement, the JBL Partybox 330, is rated 4.6/5 at $629.95 and is still sold new.
The JBL Partybox 300 is the better-sounding option. Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. Watch for: Hard to carry, too tall, drags on the ground.
The W-King T12 is the longer-running pick. A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. It is rated for 25 hours of battery against 18 for the JBL Partybox 300. It has an adjustable EQ, which the JBL Partybox 300 lacks. The catch: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound.
Buy the JBL Partybox 330, the replacement for the discontinued JBL Partybox 300; it is rated higher for sound quality than the W-King T12.

W-King T12: $439.00 Amazon $439.00 Lowest AliExpress $450.60 eBay
Pros: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. Its claimed 25-hour battery and trolley-style form make it practical where high output matters more than compact size.
Cons: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound. It is a 15kg, 75cm-tall speaker with no water rating and no app; the physical tone controls are its only meaningful way to adjust the sound.
