Short answer: the Sony ULT Tower 7 if sound quality matters most, the W-King T12 if price matters most. The Sony ULT Tower 7 ranks #1 of 39 party speakers at $648. The W-King T12 ranks #18 at $379.04, $268.96 cheaper.
What the Sony ULT Tower 7 offers: A compelling large-party value at $649.99: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. The full review praises its punchy, clean ULT1 bass, ULT2’s higher-output mode, simplified controls and unusually complete I/O: USB-C, USB-A, RCA, balanced XLR and mic input. Watch for: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers. IPX4 is splash resistance rather than full weatherproofing; the 30-hour claim requires lights off.
What the W-King T12 offers: 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. Watch for: 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.
Buy the Sony ULT Tower 7 if sound quality matters more than the price. Buy the W-King T12 if the price matters more than sound quality.
Water resistance is not close: the Sony ULT Tower 7 is rated at IPX4 (splashing), well ahead of the W-King T12 at no water resistance.
