Short answer: the Doss Soundbox Pro, unless battery life is everything, though neither ranks well in its class. The Zealot S61 is cheaper at $20 and runs an exceptional 40 hours with IPX7, but it sounds like a soup can with no bass at all. The Doss Soundbox Pro costs $49.99 and has 20W, IPX6, 20-hour battery life, an extra bass button and dual woofer drivers, though it too has barely any bass. 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 Pro. It is rated higher for sound quality and still sold new, while the Zealot S61 is discontinued.
