Short answer: the W-King X20. It ranks #37 of 89 boombox speakers by sound quality, rated 3.5/5, at $219.98. The Pioneer PBM5 ranks #89, rated 2.0/5, at $149, $70.98 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the W-King X20: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof, EQ with app control and button modes, 7.5-inch subwoofer, Bluetooth 5.3, dual pairing, MicroSD and USB playback, AUX input, TWS stereo mode with 240W combined. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The case for the Pioneer PBM5: 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. The catch: 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 $70.98 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.
