Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Doss Soundbox is the better pick: it ranks #145 of 151 medium speakers by sound quality (rated 2.1/5), against #148 (rated 2.0/5) for the Zealot S61. Both are rated below 3.0/5 among the 151 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Buy the Doss Soundbox only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.
Water resistance is not close: the Zealot S61 is rated at IPX7 (brief submersion), well ahead of the Doss Soundbox at IPX4 (splashing).
