Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox 710 ranks #7 of 13 large party speakers by sound quality at $699; the Sony ULT Tower 7 ranks #1 of 46 party speakers by sound quality at $648.
Why pick the JBL Partybox 710: At 61.7 lbs (28 kg), JBL Partybox 710 combines 2x 8” woofer, 2x 2.75” tweeter with Bluetooth and aux. The catch: Careful placement is still important for balanced bass.
The Sony ULT Tower 7 is the battery-powered option. A compelling large-party value at $648: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 50.3 lbs (22.8 kg). Its battery is rated for 30 hours, while the JBL Partybox 710 needs an outlet. It supports LDAC Bluetooth, which the JBL Partybox 710 lacks. 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.
Buy the JBL Partybox 710 ($699) for a large party speaker; the Sony ULT Tower 7 ($648) suits a party speaker instead.

Sony ULT Tower 7: $648.00 Amazon eBay
Older model: the Sony SRS-XV800 (ranked lower, rated 4.1/5). See every Sony XB and ULT generation.
Same family: the Sony ULT Field 1 (smaller model, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 3 (smaller model, rated 3.4/5), the Sony ULT Field 5 (smaller model, rated 3.5/5), the Sony ULT Tower 5 (smaller model, ranked lower, rated 4.5/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
Pros: A compelling large-party value at $648: 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.
