Short answer: the JBL Partybox On the Go. It ranks #67 of 113 boombox speakers by sound quality, rated 3.0/5, at $329.95. The Pioneer PBM5 ranks #112, rated 2.0/5, at $149, $180.95 cheaper, which does not close the gap in sound quality.
The JBL Partybox On the Go is the better-sounding pick. A battery party speaker with an included wireless microphone and a detachable shoulder strap. The tradeoff: Battery life is short, and its sound trails the rest of the Partybox line.
The Pioneer PBM5 is the longer-running 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. It is rated for 13 hours of battery against 6 for the JBL Partybox On the Go. It links with other speakers (Auracast), which the JBL Partybox On the Go cannot. It has an adjustable EQ, which the JBL Partybox On the Go lacks. 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 JBL Partybox On the Go. It is rated higher for sound quality, and the $180.95 saving on the Pioneer PBM5 is not enough to make up the difference.
