Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 7 ranks #1 of 39 party speakers by sound quality at $649.99; the Audiocase S10 ranks #12 of 14 battery-powered PA speakers by sound quality at $892.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Audiocase S10, a performer-focused battery PA. The Tower 7 offers seven drivers for 360-degree sound, a claimed 30-hour battery, wheels, IPX4 splash resistance, 10-band EQ and a full RCA/XLR/USB-C/mic input section. The Audiocase S10 offers dual 10-inch woofers rated among the loudest in the category at 125dB max SPL, a removable 30-hour battery and XLR/instrument inputs, though it is now discontinued.
Choose the Tower 7 for wheels for easier transport, immersive 360-degree party sound and a lower price: Its wheels also make it easier to roll between rooms or events. Its 360-degree drivers and ULT1/ULT2/EQ modes suit a living-room-to-backyard party speaker better than a performer-focused PA cabinet. At $649.99 it also costs less.
Choose the Audiocase S10 for higher peak output, discontinued caveats aside: It is discontinued, so check current stock and condition before buying.
Buy the Sony ULT Tower 7 at $649.99 if you want a party speaker. Buy the Audiocase S10 at $892 if you want a battery-powered PA speaker instead.
If sound quality matters at all to you, skip the Audiocase S10. It ranks near the bottom of the 14 battery-powered PA speakers, so look higher up the list instead.
If water resistance matters to you, the Sony ULT Tower 7 at IPX4 (splashing) holds up far better than the Audiocase S10 at no water resistance.

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.

Audiocase S10: $892 Discontinued eBay
Pros: One of the loudest in category.
Cons: Not great sounding at low volumes. Better sounding at louder volumes. Weird peaks in the midrange. Competes against the Soundboks but doesn’t sound as good. Discontinued.
