Short answer: the JBL Boombox 4. It ranks #20 of 113 boombox speakers by sound quality, rated 4.0/5, at $549.95. The Pioneer PBM5 ranks #112, rated 2.0/5, at $149, $400.95 cheaper, which does not close the gap in sound quality.
The JBL Boombox 4 is the better-sounding, longer-running option. An extremely loud boombox for its size with fully waterproof, dustproof build, a long battery and a flexible app EQ. It is rated for 28 hours of battery against 13 for the Pioneer PBM5. It is rated IP68 against IPX5 for the Pioneer PBM5. Watch for: Pretty overpriced for the category.
Why pick the Pioneer PBM5: 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 keeps a wired aux input, which the JBL Boombox 4 lacks. It has a microphone input for karaoke or announcements, which the JBL Boombox 4 lacks. The tradeoff: 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 Boombox 4. It is rated higher for sound quality, and the $400.95 saving on the Pioneer PBM5 is not enough to make up the difference.
