Our Take

Best for: Party hosts and outdoor event organizers who want loud, portable sound.

The JBL PartyBox 520 delivers thumping sound with AI Sound Boost, making it one of the loudest portable speakers in its class. The built-in light show adds atmosphere, and the 15-hour battery keeps the party going. It's splashproof (IPX4) and easy to move with its telescopic handle and wheels. Downside: it's heavy and the warranty is only 90 days from Woot. 95. If you need massive sound for outdoor parties, this is it.

Price Analysis

At $499.95, this is a 43% discount off the $879.95 list price. That's a significant saving for a premium party speaker. This is likely near the lowest price we've seen for this model.
