I’ve had the pleasure of using quite a few Bluetooth speakers over the years, with some of my recent favorites being the Marshall Kilburn II and Tribit StormBox Micro. So when JBL offered to let me review its new PartyBox 320, I was interested, but not necessarily ecstatic. That started to change once I began digging into the specifications and realized just how monstrous and powerful this speaker could wind up being. My suspicions were confirmed when this 36-pound monster arrived in the mail.

While unboxing the JBL PartyBox Stage 320, I couldn’t help but smile. Looking back, I think it’s because I knew that the size and heft meant that this thing was going to pack a punch. Seeing the actual speaker helped seal the deal too, with loads of easy-to-access controls, plenty of inputs around back, and wheels along the base paired with a handle up top that make it easier to roll it from one place to another. I couldn’t wait to start trying it out, so keep on reading to hear about my experience unboxing, pairing, and using this powerful speaker.
