JBL PartyBox Stage 320 vs Sony ULT FIELD 7

The Sony ULT FIELD 7 offers some key advantages over the JBL PartyBox Stage 320 when it comes to build quality and frequency response. The Sony's IP67 rating makes it a more durable, all-weather alternative to the JBL, and its switchable levels of bass via the 'ULT' button ensure there's plenty of low-end oomph available to call upon. 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, less compression at max volume (though both speakers have similar max volumes), and slightly better directivity.
