Short answer: the Sony ULT Tower 7 on measured sound quality, the Sony SRS-XP700 on price. The Sony ULT Tower 7 ranks #1 of 53 party speakers at $649.99. The Sony SRS-XP700 ranks #19 at $448, $201.99 cheaper.
The Tower 7 is the new all-rounder in Sony’s party line. It has 420W output, a claimed 30-hour battery, wheels, 360-degree seven-driver sound, 10-band EQ, and RCA/XLR/USB-C/microphone connectivity.
Choose the Tower 7 for coverage, endurance and wired sources: Its rear tweeters, longer battery claim and current input set are meaningful advantages for larger parties.
Choose the XP700 only when its legacy form factor fits better: Review the weight, battery and connection comparison below, as the newer Tower 7 is designed to replace the old high-output Sony party-speaker role.
Buy the Sony ULT Tower 7 if sound quality matters more than the price. Buy the Sony SRS-XP700 if the price matters more than sound quality.

The Two Speakers In Full
Sony ULT Tower 7: $649.99 Amazon eBay
Pros: 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.
Cons: 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.
