Our Take

Best for: Party hosts and outdoor entertainers.

The JBL PartyBox 520 delivers the biggest, boldest sound in the PartyBox lineup, thanks to AI Sound Boost that dynamically optimizes audio. With up to 15 hours of playtime, it keeps parties going all day and night. The built-in handle and wide wheels make it surprisingly easy to roll from backyard to poolside. Its lightshow is fully customizable via the JBL PartyBox app, and Auracast lets you link multiple JBL speakers for true stereo or larger setups. IPX4 splash resistance handles spills and splashes, but don't submerge it. 95 retail and matching the all-time low - this is an exceptional value for anyone wanting massive, portable party sound.

Price Analysis

At $529.95, this matches the all-time low price and is $19.23 below the 30-day average of $549.18. You save $350 off the original retail price - an exceptional deal for this speaker.
