If you are looking for the ultimate portable party speaker in 2026, the JBL PartyBox series is easily one of the most popular choices out there—and now we have the brand-new JBL PartyBox 330. However, Sony is bringing serious competition with the Sony ULT Tower 7. In today's video, we put the Sony ULT Tower 7 and the JBL PartyBox 330 head-to-head to see which speaker is right for you!

We break down the retail pricing ($650 vs $500 on sale), portability, and design differences—evaluating the 50 lb Sony ULT Tower 7 against the lighter 38 lb JBL PartyBox 330 with its built-in wheels, telescopic handle, and new top screen. We also test their IPX4 water resistance, 18-hour battery life, swappable battery convenience, DJ/mic/guitar connectivity (XLR, RCA, USB, and AI vocal karaoke features), Auracast vs. Party Connect ecosystems, and most importantly, how the dual woofers and mid-range clarity stack up in a real-world sound test.
