JBL PartyBox 710 vs Marshall Bromley 750

Unlike the battery-powered Marshall Bromley 750, the JBL PartyBox 710 only runs on A/C power. The JBL is also the larger and heavier speaker. If those aren't dealbreakers, the reward is a much fuller-sounding speaker with plenty of rumbly, deep bass on offer. On the other hand, if you need a slightly more portable option, the Marshall still puts out decently punchy bass. It also has decent directivity, so your audio sounds quite similar regardless of your listening option. Both speakers have mic and instrument inputs, but only the Marshall has XLR inputs.
