Short answer: both are discontinued, so this only matters if you are buying used. Used, the Tribit Xsound Surf is the better pick: it ranks #104 of 175 medium speakers by sound quality (rated 3.0/5), against #172 (rated 2.0/5) for the Zealot S61. If you want one new, the Tronsmart Mirtune C3 ranks #103 at $29.99.
The Tribit Xsound Surf is the better-sounding, lighter choice. Rugged rubberized frame with a metal grille. At 1 lbs (440 g) it weighs noticeably less than the Zealot S61 at 1.5 lbs (665 g). It has an adjustable EQ, which the Zealot S61 lacks. It plays in stereo from a single unit, unlike the Zealot S61. The tradeoff: Bass doesn’t go as deep as others, strange midrange peaks.
The Zealot S61 is the longer-running pick. 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 1.5 lbs (665 g) design, single full-range driver, built-in microphone, AUX input, USB-C charging. It is rated for 40 hours of battery against 10 for the Tribit Xsound Surf. The tradeoff: Sounds like a soup can, no bass at all.
Buy the Tribit Xsound Surf 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 Tronsmart Mirtune C3 instead.
