Short answer: the Turtlebox Gen 3 for better sound quality, the Pioneer PBM5 for the lower price, though neither ranks well in its class. The Turtlebox Gen 3 ranks #83 of 89 boombox speakers, rated 2.1/5, at $430. The Pioneer PBM5 ranks #89, rated 2.0/5, at $149, $281 cheaper. Both are rated below 3.0/5 among the 89 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
What the Turtlebox Gen 3 does well: Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. The tradeoff: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality.
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 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 Turtlebox Gen 3 if sound quality is the priority over the price, or the Pioneer PBM5 if the price is the priority over sound quality.
There is a real battery-life gap here: the Turtlebox Gen 3 is rated for 25 hours, the Pioneer PBM5 only 13 hours.

The Two Speakers In Full
Turtlebox Gen 3: $430.00 Amazon eBay
Older models: the Turtlebox Gen 2 (ranked lower, rated 2.1/5) and the Turtlebox (ranked lower, rated 2.1/5).
Pros: Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. Loud for its class: Williston Audio Labs measured 102 dB at max volume, well above a Kicker BF400’s 96 dB. A big 85Wh battery rated for 25+ hours, a USB-C output that charges other devices, aux and microphone inputs, and true multi-speaker Party Mode on top of stereo pairing, plus Bluetooth 5.4. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality. The amp is tuned to a V shape, with boosted lows and highs and a dip in the mids, but the boost can’t make up for shallow extension: the bass is only down 10dB at about 65Hz, so there’s little real low end despite the boomy upper bass. The amp delivers only about 12W RMS at 1% distortion. In Williston Audio Labs’ side by side test most listeners preferred the much smaller Kicker BF400 for its cleaner sound, and a Pioneer PBM5 played louder at 105 dB. Nowhere near its claimed 120dB at a reasonable measuring distance. Rattles at high volume. It charges only from its own 15V barrel plug brick, not USB-C, and has no app or EQ. Inside is essentially a car audio 6x9 two way speaker in a plastic box.

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.
