Short answer: the JBL Boombox 3 Wifi. It ranks #26 of 112 boombox speakers by sound quality, rated 3.8/5, at $389.95. The EcoXGear Defender ranks #84, rated 2.5/5, at $299.99, $89.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The EcoXGear Defender is the lighter choice. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. At 10 lbs (4.54 kg) it weighs noticeably less than the JBL Boombox 3 Wifi at 14.6 lbs (6.6 kg). It has an adjustable EQ, which the JBL Boombox 3 Wifi lacks. The tradeoff: 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 JBL Boombox 3 Wifi is the better-sounding pick. A big, waterproof stereo boombox with Wi-Fi, a long battery and enough volume for any outdoor party. It plays in stereo from a single unit, unlike the EcoXGear Defender. The catch: Bass boosted.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality, and the $89.96 saving on the EcoXGear Defender is not enough to make up the difference.
