Short answer: the ION Pathfinder 320, though neither ranks well in its class. It ranks #80 of 89 boombox speakers by sound quality, rated 2.2/5, at $129.99; the Pioneer PBM5 ranks #89, rated 2.0/5, and costs $149, so there is little reason to consider the other one. Both are rated below 3.0/5 among the 89 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
What the ION Pathfinder 320 does well: 100 hour battery at low-moderate volume. The tradeoff: Bass is not as deep as competitors.
Why pick 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 ION Pathfinder 320. It is rated higher for sound quality than the Pioneer PBM5 and costs less, which makes it the one to get unless you need something the other one does better.
Battery life favors the ION Pathfinder 320: rated for 100 hours against 13 hours for the Pioneer PBM5.

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.
