Short answer: the Sony ULT Tower 7 for better sound quality, the Sharp PS-929 for the lower price. The Sony ULT Tower 7 ranks #1 of 39 party speakers at $648. The Sharp PS-929 ranks #32 at $150, $498 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 Sharp PS-929 offers: 180W power with TWS capability to pair two units. 13-hour battery life. Rich, club-style bass, press Super Bass button for increased low-frequency power. LED flash lighting. Bluetooth wireless, auxiliary input, mic/guitar inputs, two USB ports. Wired microphone included. Vertical or horizontal positioning with built-in transport handle. Watch for: Not very deep bass
Buy the Sony ULT Tower 7 if sound quality is the priority over the price, or the Sharp PS-929 if the price is the priority over sound quality.
If sound quality matters at all to you, skip the Sharp PS-929. It ranks near the bottom of the 39 party speakers, so look higher up the list instead.
Battery life favors the Sony ULT Tower 7: rated for 30 hours against 13 hours for the Sharp PS-929.
If water resistance matters to you, the Sony ULT Tower 7 at IPX4 (splashing) holds up far better than the Sharp PS-929 at no water resistance.
