Short answer: the EcoXGear Defender, though neither ranks well in its class. It ranks #85 of 113 boombox speakers by sound quality, rated 2.5/5, at $299.99. The Monster Rockin’ Roller 270 ranks #104, rated 2.1/5, at $208.99, $91 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 113 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $199.99.
The EcoXGear Defender is the better-sounding, lighter option. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. At 10 lbs (4.54 kg) it weighs much less than the Monster Rockin’ Roller 270 at 28.7 lbs (13 kg). It is rated IP67 against IPX4 for the Monster Rockin’ Roller 270. The catch: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
The Monster Rockin’ Roller 270 is the longer-running option. A wheeled party speaker with an enormous battery, sound spread wide around it and a wireless phone charging pad. It is rated for 100 hours of battery against 25 for the EcoXGear Defender. Watch for: Bass not as deep as competitors, less neutral than ION speakers.
Buy the EcoXGear Defender. It is rated higher for sound quality, and saving $91 with the Monster Rockin’ Roller 270 does not make up for the sound-quality gap.
