Our Verdict

JBL PartyBox 300

JBL Boombox 2

The JBL PartyBox 300 and the JBL Boombox 2 are similar speakers with a few different features. The Boombox has a more open soundstage, and it's more portable thanks to its smaller size. It's also rated IPX7 for water resistance, though we don't currently test for this. However, the PartyBox can get louder and it has much less compression at max volume.
