Short answer: the JBL Boombox 3 Wifi on measured sound quality, the EcoXGear Defender on price. The JBL Boombox 3 Wifi ranks #22 of 75 boombox speakers at $389.95. The EcoXGear Defender ranks #59 at $249.99, $139.96 cheaper.
What the EcoXGear Defender offers: 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. Watch for: 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.
What the JBL Boombox 3 Wifi offers: Loudest speaker in the category. Slightly better frequency response than the non-wifi version. Watch for: Bass boosted. Dip at 160hz
