Our Verdict

JBL PartyBox Stage 320

Sony ULT FIELD 7

The Sony ULT FIELD 7 offers some key advantages over the JBL PartyBox Stage 320. The Sony speaker's IP67 rating makes it a more durable, all-weather alternative to the JBL, and its switchable bass levels via the 'ULT' button help you tailor the low-end to your preferences. It's also quite a bit more portable and can be carried around over your shoulder using its carrying strap. That said, the JBL boasts a much longer battery life and slightly better directivity.
