Short answer: the Monster Rockin’ Roller 270, though neither ranks well in its class. It ranks #104 of 113 boombox speakers by sound quality, rated 2.1/5, at $208.99. The Pioneer PBM5 ranks #112, rated 2.0/5, at $149, $59.99 cheaper, a saving that is not big enough to make up the sound-quality gap. 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 Monster Rockin’ Roller 270 is the longer-running choice. 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 13 for the Pioneer PBM5. The tradeoff: Bass not as deep as competitors, less neutral than ION speakers.
The Pioneer PBM5 is the lighter pick. A loud karaoke boombox with two mic inputs, a guitar input, lights, a shoulder strap and a choice of USB-C or AC power. At 14.1 lbs (6.4 kg) it weighs much less than the Monster Rockin’ Roller 270 at 28.7 lbs (13 kg). It links with other speakers (Auracast), which the Monster Rockin’ Roller 270 cannot. Watch for: Williston Audio Labs was not impressed with its sound: there is very little bass below 100Hz, and the amplifier’s output has a big dip from 1.6kHz to 10kHz that leaves the upper mids and treble recessed.
Buy the Monster Rockin’ Roller 270. It is rated higher for sound quality, and saving $59.99 with the Pioneer PBM5 does not make up for the sound-quality gap.
