Short answer: the Tribit Stormbox Flow on measured sound quality, the Zealot S61 on price. The Tribit Stormbox Flow ranks #49 of 136 medium speakers at $60. The Zealot S61 ranks #134 at $20, $40 cheaper.
What the Tribit Stormbox Flow offers: Up to 30 hours of battery life - roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Watch for: Not stereo. Midrange and bass are weirdly recessed about 4db below 700hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
What the Zealot S61 offers: 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 665g design, single full-range driver, built-in microphone, AUX input, USB-C charging Watch for: Sounds like a soup can, no bass at all. Weird frequency response all over.
Buy the Tribit Stormbox Flow when sound quality outweighs the price for you, and the Zealot S61 when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Zealot S61. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
