Same family: the Marshall Bromley 150 (smaller model, rated 3.8/5) and the Marshall Bromley 450 (smaller model, rated 3.7/5).

Pros: A stylish battery party speaker that spreads sound evenly in every direction, with a very long rated battery. Much wider, more consistent off-axis dispersion than the JBL Partybox 720, which only fires forward: the Marshall’s standout feature, sounding about the same from any angle.

Cons: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720. Not a great frequency response overall, with some midrange peaks. Only basic bass/treble controls, no full custom EQ like the JBL Partybox 720’s app. Default bass (dynamic mode) is overdone out of the box and needs trimming.

Is the Marshall Bromley 750 right for you?

Buy it if

  • you want the best value: the higher-rated JBL Partybox 710 costs about $351 less.
