Short answer: the Monster Rockin’ Roller 270, though neither ranks well in its class. It ranks #82 of 89 boombox speakers by sound quality, rated 2.1/5, at $249. The Pioneer PBM5 ranks #89, rated 2.0/5, at $149, $100 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 89 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
Why pick the Monster Rockin’ Roller 270: 100 hour battery life. The catch: Bass not as deep as competitors, less neutral than ION speakers.
What the Pioneer PBM5 does well: Loud for its size: Williston Audio Labs measured about 105 dB at 2 meters, louder than the Turtlebox Original Gen3 and Kicker Bullfrog BF400 in the same test. 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 $100 with the Pioneer PBM5 does not make up for the sound-quality gap.

Pioneer PBM5: $149.00 Sam’s Club eBay
Pros: Loud for its size: Williston Audio Labs measured about 105 dB at 2 meters, louder than the Turtlebox Original Gen3 and Kicker Bullfrog BF400 in the same test. Two 5.25 inch woofers and two 2 inch tweeters with a port tuned to 48Hz, two microphone inputs plus a guitar input with bass, treble and reverb controls for the mics, aux and USB playback, IPX5 splash resistance, RGB lights, a shoulder strap, Bluetooth 5.4 with Auracast, and charging from either USB-C or the included AC cord. A rated 13 hours at 60% volume.
Cons: 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. None of the EQ presets fixed it, and a 1990 JVC boombox sounded cleaner. The amp measured about 90W in total, not the claimed 300W, and only about 23W per woofer channel on battery. USB playback is MP3 only, there is no audio output and no microphone in the box, and it is sold only at Sam’s Club.
