Short answer: the Monster Rockin’ Roller 270, if you are buying new. The JBL Boombox 2 ranks higher than it (#40 vs #84 of 91 boombox speakers, 3.5/5 vs 2.1/5) but is discontinued, so only consider it used; the Monster Rockin’ Roller 270 is still sold new at $249.
The JBL Boombox 2 is the better-sounding, deeper-bass option. 24 hour battery life (default volume); 20+ hours even at 60% volume. Its bass reaches about 46Hz before falling 10dB, against 53Hz for the Monster Rockin’ Roller 270. At 13 lbs (5.9 kg) it weighs much less than the Monster Rockin’ Roller 270 at 28.7 lbs (13 kg). It is rated IPX7 against IPX4 for the Monster Rockin’ Roller 270. Watch for: Somewhat bass heavy and boomy.
The Monster Rockin’ Roller 270 is the longer-running choice. 100 hour battery life. It is rated for 100 hours of battery against 24 for the JBL Boombox 2. It has an adjustable EQ, which the JBL Boombox 2 lacks. The catch: Bass not as deep as competitors, less neutral than ION speakers.
Buy the Monster Rockin’ Roller 270, since the JBL Boombox 2 is discontinued and only worth hunting down used.
