JBL PartyBox Stage 320
JBL PartyBox 330
The JBL PartyBox 330 is a slight refinement of the JBL PartyBox Stage 320. They're similarly sized rolling party speakers, get to similar maximum volume levels, have replaceable batteries, and carry the same IPX4 rating. The Stage 320 actually lasts a little longer off a single charge, but the 330 adds USB-C audio playback and an optical input. The 330 also sounds somewhat more consistent as you move off to the side, although you'll still want to stay in front of either speaker for the best sound.
