Short answer: it depends on how much the Soundboks name and portability are worth to you. The Defender ranks #59 of 75 boombox speakers at $334.99; the Soundboks Go ranks #25 of 39 in the party class at $799, $464.01 more.
The Defender’s case is loud output for the money: 121dB at around $250, IP67 waterproofing that floats, and a 25-plus hour battery, with a built-in flashlight and bottle opener as genuine extras. Its cons are narrow: bass that doesn’t reach as deep as competitors.
The Soundboks Go leans on battery life and brand durability, an exceptional 40-hour rating at mid-volume and a swappable second battery, though it isn’t as loud, neutral, or bass-heavy as the JBL Partyboxes it’s compared against in our notes.
Buy the Defender for genuinely loud output at a fraction of the price. Buy the Soundboks Go if the brand and its portability-focused design specifically matter to you.
If sound quality matters at all to you, skip the EcoXGear Defender. It ranks near the bottom of the 75 boombox speakers, so look higher up the list instead.
Water resistance is not close: the EcoXGear Defender is rated at IP67 (brief submersion), well ahead of the Soundboks Go at no water resistance.

The Two Speakers In Full
EcoXGear Defender: $334.99 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.
