Short answer: the EcoXGear Defender, though neither ranks well in its class. It ranks #72 of 89 boombox speakers by sound quality, rated 2.5/5, at $299.99. The Pioneer PBM5 ranks #89, rated 2.0/5, at $149, $150.99 cheaper, a saving that is not big enough to make up the sound-quality gap. 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 EcoXGear Defender does well: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. The catch: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
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 EcoXGear Defender. It is rated higher for sound quality, and saving $150.99 with the Pioneer PBM5 does not make up for the sound-quality gap.
There is a real battery-life gap here: the EcoXGear Defender is rated for 25 hours, the Pioneer PBM5 only 13 hours.

The Two Speakers In Full
EcoXGear Defender: $299.99 Amazon eBay
Pros: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode.
Cons: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited. The default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode. Bass does not reach as deep as competitors.

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.
