Short answer: the W-King X20. It ranks #43 of 113 boombox speakers by sound quality, rated 3.5/5, at $229.99. The Pioneer PBM5 ranks #112, rated 2.0/5, at $149, $80.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
The W-King X20 is the better-sounding, longer-running option. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated for 24 hours of battery against 13 for the Pioneer PBM5. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The case for 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 links with other speakers (Auracast), which the W-King X20 cannot. 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 W-King X20. It is rated higher for sound quality, and saving $80.99 with the Pioneer PBM5 does not make up for the sound-quality gap.
