Short answer: the Sony ULT Tower 5. It ranks #5 of 54 party speakers by sound quality, rated 4.5/5, at $448; the Marshall Bromley 450 ranks #26, rated 3.7/5, and costs $569.99, so there is little reason to consider the other one.
The Sony ULT Tower 5 is the better-sounding choice. A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It supports LDAC Bluetooth, which the Marshall Bromley 450 lacks. Watch for: It has a shorter 20-hour battery claim than the Sony ULT Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
The Marshall Bromley 450 is the longer-running pick. A rugged, weather resistant party speaker with drivers on every side, a swappable battery, and mic and guitar inputs. It is rated for 40 hours of battery against 20 for the Sony ULT Tower 5. Watch for: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed.
Buy the Sony ULT Tower 5. It is rated higher for sound quality than the Marshall Bromley 450 and costs less, which makes it the one to get unless you need something the other one does better.
