So over the last few years, the JBL PartyBox 310 has been my favorite box speaker to use and to recommend. It sounds great and it has a ton of bass, its easy to transport thanks to its built in wheels and its has a dynamic looking light feature… but now we have the JBL PartyBox Stage 320 which has some major upgrades over the 310, and the design of this speaker has just be so refined, so today we’re going to checkout the JBL PartyBox 320, were going to see if its worth upgrading from the 310… and yes you can believe the hype.
