These sit in different size classes, so this is not a straight ranking comparison. The Sony ULT Tower 5 ranks #5 of 53 party speakers by sound quality at $448; the Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95.
The Sony ULT Tower 5 is the longer-running choice. A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It is rated for 20 hours of battery against 4 for the Zealot ZE41. 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.
What the Zealot ZE41 does well: A huge boombox with lots of bass, volume and play time for the money. Watch for: The heaviest and biggest boombox speaker around.
Buy the Sony ULT Tower 5 at $448 for a party speaker, or the Zealot ZE41 at $219.95 for a boombox speaker instead.
