Our Verdict

JBL PartyBox 710

Sony ULT TOWER 9AC

Choosing between the JBL PartyBox 710 and Sony ULT TOWER 9AC comes down to preferences for most people because they're similarly large and hefty. If you want a balanced sound with less compression in the bass and better directivity, the JBL slightly wins out. It's also IPX4-rated, while the Sony's control panel is apparently splashproof-only. Connectivity is fairly similar: mic and guitar inputs, wired via an AUX cable, Bluetooth, and each supports stereo and party modes with compatible speakers. The Sony offers the LDAC Bluetooth codec, which is a step above the JBL, and an Optical port for TVs. Still, it may come down to something as simple as which one has a bassier tuning (the Sony) or which one's app interface you prefer.
