Short answer: it depends on how much the Soundboks name and portability are worth to you. The Defender ranks #85 of 113 boombox speakers at $299.99; the Soundboks Go ranks #37 of 53 in the party class at $799, $499.01 more. The Soundboks Go is discontinued; its replacement is the Soundboks Mix.
The Defender’s case is loud output for the money: 121dB at $299.99, 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.
Water resistance is not close: the EcoXGear Defender is rated at IP67 (brief submersion), well ahead of the Soundboks Go at no water resistance.
