Head to Head: Key Differences
The 320 and 520 serve completely different use cases based on how you plan to use them. Think of the 320 as your mobile companion and the 520 as your stationary powerhouse.
Power output separates these speakers dramatically. The 520 pumps out 400W compared to the 320’s 240W, giving you 67% more raw power for larger venues.
If you need serious volume and deep bass that fills a massive room, the 520 wins here.
Battery life favors the 320 with 18 hours versus the 520’s 15 hours. For outdoor events where you can’t access power outlets, the 320 keeps running longer without a charge.
The 520 relies heavily on AC power, making it less flexible for remote locations.
Portability heavily favors the 320. Wheels and a telescopic handle make moving this speaker quick and simple, even solo.
The 520 lacks wheels and feels more like a permanent installation piece for your venue.
Input options reflect different audiences. The 520 features dual XLR inputs perfect for DJs connecting professional mixers and equipment.
The 320 offers mic and guitar inputs with independent gain control, making it better for live performers and casual events.
Splash proof protection comes standard on the 320, keeping it safe during outdoor use and accidental spills. The 520’s protection level isn’t emphasized, suggesting it stays indoors or under cover.
Choose the 320 if you move between venues frequently and need portability. Pick the 520 if you host stationary parties and demand maximum volume and bass impact. Your event location and equipment setup should guide your decision.
Which One Should You Buy
The JBL PartyBox 520 stands out as the overall winner in this comparison. It offers 400W of power, far more than the 320’s 240W, and adds dual XLR inputs for professional use.
This makes the 520 a stronger all-around performer for serious sound needs. It does trade some portability and battery life to achieve this power boost.
Still, both speakers shine in different settings. Your choice depends on whether you value power or portability more.
