Short answer: the JBL Boombox 3 Wifi. It ranks #25 of 89 boombox speakers by sound quality, rated 3.8/5, at $389.95. The Monster Rockin’ Roller 270 ranks #82, rated 2.1/5, at $249, $140.95 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the JBL Boombox 3 Wifi: Loudest speaker in the category. Watch for: Bass boosted.
Why pick the Monster Rockin’ Roller 270: 100 hour battery life. The tradeoff: Bass not as deep as competitors, less neutral than ION speakers.
