Short answer: the JBL Partybox On the Go. It ranks #47 of 76 boombox speakers by sound quality, rated 3.0/5, at $300. The Monster Rockin’ Roller 270 ranks #70, rated 2.1/5, at $249, $51 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the JBL Partybox On the Go: JBL Partybox On the Go uses 5.1” woofer + tweeters. The catch: Bass is limited by its 49Hz specification.
The case for the Monster Rockin’ Roller 270: 100 hour battery life. Watch for: Bass not as deep as competitors, less neutral than ION speakers.
Buy the JBL Partybox On the Go. It is rated higher for sound quality, and saving $51 with the Monster Rockin’ Roller 270 does not make up for the sound-quality gap.

A wireless microphone is included. Measured bass extension of 49Hz (-10dB).
