Short answer: the Zealot ZE41 for bass, play time and max volume, the Monster Rockin’ Roller 270 for battery life. The ZE41 is called the absolute best value in the boombox class for bass performance, play time and max volume, though it is the heaviest and biggest boombox around. The Monster’s 100 hour battery is its main draw, with bass that is not as deep as competitors and a less neutral sound than ION speakers.
Buy the Zealot ZE41. It is rated higher for sound quality, and the $10.96 you would save on the Monster Rockin’ Roller 270 does not close the gap.
